The Crazy 6-Year Mission to Save Winchester Cathedral

Summary

Building on Unstable Ground: The medieval Winchester Cathedral was constructed on peat, a poor foundation choice due to its proximity to the royal palace and river Itchen, which eased material transport. Builders used elm logs to create a raft-like base.

Rotten Foundations: Water fluctuations caused elm logs to rot over centuries, threatening structural collapse. Cracks appeared, making immediate intervention critical.

Diving Innovation: Engineer Francis Fox proposed underwater reconstruction, hiring diver William Walker, who worked in near-complete darkness for six years to stabilize the cathedral.

Monumental Effort: Walker placed 900,000 bricks, 114,900 concrete blocks, and 25,800 cement bags under the foundation while enduring harsh conditions.

Dedication Beyond Work: Walker commuted 65 miles weekly to see his family, showcasing unwavering commitment.

Recognition and Legacy: Despite heroic efforts, Walker’s contributions received limited recognition. A statue in his honour was misattributed initially, further highlighting his underappreciation.

Tourism and Pilgrimage: Cathedrals functioned as religious and economic hubs, attracting pilgrims with relics to fund maintenance. Winchester once stood as England’s capital and a pilgrimage site.

Fire Risks: Historical and modern threats, like fire hazards, emphasise the vigilance required to preserve such architectural marvels.

Should You Insulate Under a Suspended Wooden Floor?

Insulating under a suspended wooden floor is a practical solution to enhance the thermal efficiency of your home. While some argue against it due to concerns about ventilation and moisture, proper installation can deliver significant benefits without these drawbacks.

Benefits of Insulation

The most immediate advantage of underfloor insulation is the warmth it brings to your living space. Homeowners often notice a dramatic difference on the very day of installation. Floors feel noticeably warmer, drafts significantly reduce, and overall comfort improves. This is particularly important in older homes with wooden floors that can be prone to air leakage.

Materials and Techniques

There are various materials suitable for insulation, including rock wool and polystyrene. Rock wool is popular due to its fire-resistant properties and ease of use. It can be secured between floor joists using netting or straps. For homes with limited crawl space, insulation can be fed through gaps in the floorboards by removing a few boards and strategically placing the material.

Addressing Ventilation and Moisture

One common concern is that insulation might trap moisture, potentially causing dampness. However, as long as the underfloor area is well-ventilated, this is unlikely to be a problem. Air circulation ensures that any moisture passing through the insulation is removed naturally. It’s crucial to avoid adding vapour barriers under the insulation, as they can interfere with this process and may inadvertently cause more harm than good.

Long-Term Value

The initial investment in underfloor insulation is modest compared to the long-term benefits. Besides improving thermal comfort, it leads to energy savings year after year, making it a cost-effective upgrade with a lifespan of 20–40 years.

Insulating under a suspended wooden floor can transform your home’s comfort and energy efficiency with proper installation.

__________________________________

The Truth About Cavity Wall Ventilation

Let’s delve into the frequently misunderstood topic of cavity wall ventilation. Hosted by Roger Bisby from the Skill Builder channel, this discussion addresses one of the most common questions homeowners and builders face: Should cavity walls be ventilated, or is sealing them a better option?

Cavity walls are a crucial component of modern home construction, designed to prevent water penetration by creating a barrier that allows rainwater to drain harmlessly to the ground. However, adding insulation and air bricks has created confusion about whether cavities require ventilation to “breathe.”

Roger debunks misconceptions, such as the belief that air bricks ventilate the cavity. Instead, he clarifies their role in ventilating subfloor spaces or providing direct airflow into rooms. He also explains the importance of sealing the top of the cavity to prevent issues like loft condensation caused by evaporating dampness from open cavities.

The video highlights how a sealed cavity improves insulation performance. Eliminating air movement makes trapped air within the cavity a natural insulator, enhancing energy efficiency and reducing heat loss. Practical advice includes using mastic or silicone to seal gaps around windows, doors, and other openings, ensuring maximum insulation value—even without additional cavity wall insulation.

Whether you’re a homeowner looking to improve your property’s insulation or a professional seeking clarity on best practices, this video provides straightforward, actionable guidance on cavity wall ventilation. With over 1,000 home building and renovation videos, the Skill Builder channel is your go-to source for tackling common construction challenges.

__________________________________

Cavity Wall Ventilation – What You Need To Know
  • Purpose of Cavity Walls: The primary function of cavity walls is to stop water penetration by allowing rain to run down the cavity and soak into the ground.
  • Common Misconceptions: Air bricks are often misunderstood; they ventilate the subfloor space, not the cavity itself.

❌ Sealing Is Key: Open cavities can lead to condensation issues in the loft due to evaporation. Proper sealing prevents air movement, improving insulation.

  • Insulation Benefits: Trapped air within a sealed cavity acts as a natural insulator, enhancing energy efficiency.
  • Practical Advice: Seal gaps around windows, doors, and air bricks using mastic or silicone to optimize the cavity’s insulation.

How to Stop Damp in Your Home: A Comprehensive Guide

Damp issues can wreak havoc on homes, particularly in basements and below-ground areas where moisture is most persistent. Addressing dampness effectively requires careful preparation, the right materials, and a thorough application process. This article explores proven strategies to stop damp for good, based on techniques demonstrated in the video, The Easiest Way To Stop Damp For Good.

Step 1: Preparing the Wall Surface

The first step to stop damp is ensuring a smooth and stable surface. Applying a straightening coat of render is essential to create a flat base. This eliminates any unevenness that could compromise the adhesion of waterproofing materials. For walls with rough brickwork or paint, levelling out the surface is critical to prevent water ingress through gaps or weak points.

Step 2: Applying Polymer-Reinforced Waterproofing

A key innovation to stop damp, is using polymer-reinforced cementitious coatings, such as Safeguard TS+. These coatings are specially designed for below-ground applications. The polymer binds the cement, prevents micro-cracking, and creates a microporous layer that repels water, allowing the wall to “breathe.” This property is crucial for managing trapped moisture and reducing the risk of future damp issues.

The application involves two coats, with 2 to 4 hours of drying between each coat. The colour change from blue to brown indicates readiness for the second coat, ensuring complete coverage and long-term protection.

Step 3: Choosing Advanced Solutions for Severe Cases

In cases of significant water penetration, membrane systems offer an alternative to tanking slurries. These systems create a cavity behind the membrane for moisture to drain into a channel, which can be pumped out. This approach is ideal for basements facing persistent or high-volume water intrusion.

Step 4: Using Breathable Materials for Finishing

For finishing, high lime plaster is an excellent choice. Its breathability allows it to absorb and release condensation, acting as a buffer for moisture. This makes it particularly suitable for damp-prone areas. Additionally, it resists salt ingress, preventing surface deterioration.

Effective damp-proofing requires careful preparation, advanced materials, and the right techniques. Whether using tanking slurries, membrane systems, or breathable plasters, each method addresses specific challenges. Following these steps, homeowners can safeguard their properties and ensure a dry, durable living space.

Water features like fountains or small ponds introduce tranquil sounds and attract wildlife, creating a peaceful atmosphere. Consider installing a small pond with aquatic plants and fish, which can become a focal point in your garden.

Incorporating art—whether through sculptures, decorative stones, or even murals—adds a personal touch and sparks conversation. Each element brings a new dimension to your garden, inviting exploration and admiration.

Designing Functional Zones

When planning your outdoor space, consider creating functional zones that cater to various activities. Define areas for relaxation, dining, gardening, or play.

For instance, designate a comfortable seating area with outdoor furniture to unwind with a book or enjoy tea. Use outdoor rugs and cushions to define this space and make it feel inviting.

A dining area with a table and chairs can be a perfect gathering spot for those who love entertaining. Enhance this zone with a pergola or shade sails to provide cover and create an intimate atmosphere.

To further define these spaces, consider incorporating decorative fence panels. These panels can act as visual dividers, adding structure and style while helping delineate your garden’s different areas.

If you have children or pets, consider incorporating a play zone with safe, soft surfaces and engaging activities like a sandbox or a small climbing structure. Dividing your garden into functional zones improves usability and adds visual interest, making the space feel more dynamic and thoughtfully designed.

Harnessing the Power of Lighting

Lighting plays a crucial role in garden design, transforming the mood and usability of outdoor spaces. By thoughtfully integrating various lighting options, you can extend the usability of your garden into the evening hours.

String lights hung across seating areas create a whimsical ambience. Meanwhile, pathway lights can guide visitors safely through your outdoor space.

Consider using solar-powered lights for an eco-friendly option that requires minimal maintenance. These lights absorb sunlight during the day and illuminate your garden at night without increasing your electricity bill.

Additionally, incorporating spotlights on key features—such as trees, plants, or architectural elements—can enhance their beauty and draw attention to your garden’s unique aspects.

For a modern touch, consider installing smart lighting systems. These allow you to control the brightness and colour of your lights through an app. This flexibility can help set the perfect mood for any occasion, whether a quiet evening or a lively gathering.

Addressing Damp Problems with Practical Solutions

Damp problems are a common concern for homeowners, with many rushing to costly remedies without fully understanding the root cause. Surprisingly, most of these issues stem not from structural defects but from condensation—a manageable and often overlooked problem. By addressing the basics of humidity control, homeowners can save money and protect their property.

Understanding Condensation

Condensation occurs when warm air laden with moisture comes into contact with cooler surfaces, such as walls or windows, causing water to accumulate. This phenomenon is frequently mistaken for structural dampness, leading to unnecessary expenses on damp-proofing measures that fail to resolve the problem.

Monitoring Humidity Levels

A simple, affordable solution lies in measuring humidity levels within the home. For as little as £5, a small humidity sensor can provide valuable insights into whether a household is at risk. Ideally, relative humidity levels should stay below 60%. Prolonged exposure to higher levels encourages mould growth, damaging walls, furniture, and health.

Cost-Effective Solutions

Investing in a dehumidifier can provide immediate relief if high humidity is detected. These devices create a healthier indoor environment by removing excess moisture from the air. Additionally, improving ventilation—by opening windows or using extractor fans—can drastically reduce condensation buildup.

Observational Techniques

Homeowners are encouraged to check each room’s humidity levels, as conditions can vary significantly within the same property. For instance, seldom-used rooms may retain lower humidity due to natural drafts, as demonstrated with single-glazed sash windows. Contrary to modern practices, such ventilation can be beneficial.

Assess your home’s humidity before committing to expensive treatments. By addressing condensation with affordable tools and methods, you can resolve damp problems efficiently and sustainably, ensuring your home remains a comfortable and healthy space.

Guide: Fixing Dead Zones in Underfloor Heating

This guide provides a step-by-step approach to diagnosing and resolving dead zones in an underfloor heating system.

Step 1: Identifying the Problem

To detect cold spots in your underfloor heating system, walk barefoot over the flooring to sense any uneven warmth. For a more precise identification, use a thermal imaging camera, such as a plug-in device for phones, to map the pipe temperatures visually.

Step 2: Diagnosing Airlocks

Airlocks often cause inconsistent heating in one or more circuits. These issues are more likely to occur in systems with manifolds installed at uneven levels. To prevent airlocks, position the manifold higher than the underfloor circuits if possible, and ensure the system is vented properly during installation.

Step 3: Flushing the System

Locate the manifold valves to prepare for flushing. The fill valve, usually at the top, introduces water, while the drain valve at the bottom expels air or debris. Attach a garden hose to the fill valve for high-pressure water input and a drain hose to the bottom valve to flush out debris. One at a time, flush each circuit to clear any airlocks, sediment & fix any dead zones.

Step 4: Using Boiler Pressure

Open the boiler’s fill valve to pressurise the system as an efficient alternative to using hoses. Close off all circuits except one, and let the water flow through that circuit. Repeat the process for all circuits to ensure they are completely debris-free.

Step 5: Adjusting Flow Rates

After flushing, restore balance in your heating system by resetting the flow rates for each circuit. Consult your recorded flow rate settings and adjust the valves to achieve a consistent flow rate of approximately 2 litres per minute per circuit or as specified for your system.

Step 6: Maintenance Tips

To maintain your underfloor heating system, flush it every few years to remove buildup and sediment. After flushing, add an inhibitor solution to prevent corrosion and sludge formation. Regularly monitor the flow meters to ensure consistent heating across all circuits and avoid dead zones.

Why and When to Power Flush Your Heating System

A power flush is an essential maintenance procedure for central heating systems, designed to remove sludge, rust, and other debris from pipes, radiators, and boilers. Over time, these deposits can accumulate, reducing the efficiency of your heating system and potentially causing blockages or damage.

A power flush helps restore the system’s efficiency, improve heat distribution, and prolong the life of your boiler.

You should consider it if you notice cold spots on your radiators, noisy pipes, or an overall drop in heating performance. It’s also a good idea to install a new boiler to ensure the existing system is free from debris that could damage the new equipment.

In areas with hard water or systems prone to sludge buildup, regular flushing is recommended every 5-6 years.

Caution with DIY Power Flush

While attempting a DIY powerflush to save money may be tempting, it’s not as straightforward as it seems.

A proper power flush requires specialist equipment, such as a professional-grade pump, which can be expensive to hire.

Moreover, you’ll need to understand your heating system’s layout to avoid causing damage.

Improper techniques, excessive pressure, or leaving valves in the wrong position could lead to leaks, burst pipes, or damage to your boiler.

Older systems, in particular, are vulnerable, as the process can dislodge rust, which might create more problems.

For DIY enthusiasts, using a chemical flush or installing a magnetic filter may be safer alternatives. If you’re determined to do a full power flush yourself, research thoroughly and proceed cautiously.

However, hiring a professional ensures the job is done safely, efficiently, and with the right tools. In most cases, it’s worth the investment for peace of mind.

London’s Gas Streetlights: A Glimpse into the Past

Gas streetlights, iconic symbols of the city of London’s historic charm, have illuminated its streets since the early 19th century. Introduced in 1807 along Pall Mall, gas lighting revolutionised urban life, improving safety and extending activity after dark. By the mid-19th century, thousands of gas lamps lit up the city, becoming integral to London’s Victorian identity.

The gas lamps were initially powered by coal gas, a by-product of coal carbonisation. Lamplighters used long poles to manually light and extinguish each lamp, a task that required precision and routine. With their distinctive uniforms, these lamplighters became familiar figures in London’s streetscape. Over time, innovations such as clockwork mechanisms and pilot lights reduced the need for manual operation.

Today, an estimated 1,500 gas streetlights remain in London, preserved as functional monuments to a bygone era. These lamps, often found in areas like Covent Garden, Westminster, and the Royal Parks, continue to evoke the romance of Dickensian London. They are lovingly maintained by a small team of skilled engineers, ensuring they remain operational despite the encroachment of modern electric lighting.

Beyond their historical significance, London’s gas lamps are celebrated for their unique aesthetic. Their soft, warm glow creates a nostalgic ambience that contrasts sharply with the starkness of LED lighting. For residents and visitors alike, they serve as tangible links to a time when gaslight transformed the cityscape and brought new possibilities to nocturnal life.

Efforts to preserve these lamps highlight their cultural importance. Campaigns and heritage initiatives aim to protect these remnants of London’s industrial history, recognising them as symbols of the city’s resilience and innovation. The gas streetlights of London are not just functional objects but enduring artefacts of the city’s rich and layered past.

Ecological Building Systems, a leading supplier of natural building products for sustainable construction, has launched an exciting new flexible insulation product for roofs, walls, ceilings and floors called IndiBreathe Flex as part of an exclusive partnership with IndiNature.

IndiBreathe Flex is breathable, natural, high-performance thermal and acoustic insulation that helps regulate humidity within a building structure for better indoor air quality. The innovative insulation material has also received BBA Approval Inspection Testing Certification (24/7266) for Timber frame, pitched roof constructions, and suspended timber intermediate floors and ground floors.

Ideal for use in new builds and retrofits and particularly for timber frame constructions, IndiBreathe Flex provides superior thermal performance with a low thermal conductivity of 0.039 W/mK.  It also offers excellent overheating protection for buildings during summer, thanks to its combination of high density and exceptional specific heat capacity (2370 J/kgK), which helps keep indoor temperatures stable in warm and cold weather.  As part of a sustainable build, IndiBreathe Flex helps to reduce energy consumption and lower heating and cooling costs.

Niall Crosson, Technical Director at Ecological Building Systems, explains: “We’re delighted to be working in partnership with IndiNature to offer architects, builders, contractors and homeowners a truly sustainable solution for creating energy efficient, comfortable and healthy indoor environments.  The BBA Certificate provides reassurance to self-builders, architects and contractors that this natural insulation product will perform effectively over the long term when installed according to guidelines.  IndiBreathe Flex epitomises the resource-efficient use of raw materials like jute and locally sourced hemp, with a carbon negative footprint from cradle to gate, creating a thermal insulation material with unique characteristics that outperform many synthetic alternatives.”

As the sole UK and Ireland distributor of IndiBreathe Flex, Ecological Building Systems offers this exciting new insulation material in a range of standard sizes and thicknesses.

IndiNature Co-founder & CTO, Scott Simpson, who led the certification process, said: “At IndiNature we’re proud to supply healthy, low carbon products manufactured in the UK and made from natural hemp fibres grown on UK farms. The addition of jute fibres from recycled coffee bags in IndiBreathe Flex offers an option for a lighter flexi-batt insulation with excellent performance and is also part of our commitment to taking care of the environment by reducing waste.”

“This means customer’s build projects made with IndiBreathe Flex will not only continue to benefit from vapour-open, carbon capturing materials but also benefit from even more positive environmental impacts. A good story for the health of buildings and the health of our planet”.

As a result of its vapour open hygroscopic composition, IndiBreathe Flex can absorb excess moisture to effectively help regulate humidity and lower the risk of interstitial condensation and mould forming within the building envelope.  This ensures a drier and more durable building fabric with occupants benefiting from a healthier and more comfortable living environment.

IndiBreathe Flex has excellent environmental credentials as it is manufactured from UK grown industrial hemp and recycled jute fibres from repurposed coffee bean sacks.  The combination of its carbon negative production process combined with the resource efficient use of raw materials helps reduce embodied carbon emissions, making it a low impact choice for environmentally conscious projects.  The product is designed to last the lifetime of the building and can be reused at the end of its life, ensuring waste is minimised.

In addition to its thermal properties, IndiBreathe Flex also provides acoustic benefits by dampening external noise, with its dense natural fibre composition contributing to quieter and more private living and working spaces. 

IndiBreathe Flex insulation is light and soft to the touch and is therefore easy to handle and install, without the need for personal protective equipment. Although flexible, it is rigid enough to prevent settlement which ensures long term performance and eliminates the risk of gaps forming or it becoming compacted over time.

BBA IndiBreatheFlex

British Board of Agrément Sales & Marketing Director, Katy Roberts said: “We are delighted to have worked with IndiNature on their second BBA Agrément certificate for industrial hemp insulation, with this next generation blending recycled jute fibre content which helps support a more circular economy and effective resource use. Working with manufacturers like IndiNature as they move through the BBA’s rigorous and robust certification assessment process, we are encouraged by the commitment to quality and safety throughout the industry; especially in areas like bio-based construction materials in the UK.”

Plaster Patching Repair

Plaster patching repairs are common in UK homes, particularly in older properties where wear and tear or previous repairs have failed. Whether a small dent in the wall or a larger area of damaged plaster, using suitable materials ensures a lasting and professional finish. In this guide, we’re using Dryzone Hi-Lime Renovation Plaster from Safeguard Europe, a versatile and breathable plaster ideal for patchwork in traditional and modern homes.

Hi-Lime Renovation Plaster is particularly suitable for UK properties with solid walls that require a breathable repair material. Traditional gypsum plasters can trap moisture, causing damp issues in heritage buildings or walls that need to “breathe.” Hi-Lime, on the other hand, is a high-quality lime-based plaster that accommodates the needs of these walls while delivering a smooth finish.

Preparing for Plaster Patching
Start by removing loose or damaged plaster from the area, ensuring the repair edges are neat. Clean the substrate to remove any dust, grease, or contaminants. If the underlying surface is highly absorbent, dampen it slightly to prevent the plaster from drying too quickly.
Applying Hi-Lime Renovation Plaster

Mix the Hi-Lime Renovation Plaster according to the manufacturer’s instructions, ensuring a consistent, lump-free texture. Apply the plaster in thin layers using a plastering trowel, pressing firmly to achieve good adhesion. Build up the plaster in layers for deeper repairs, allowing each one to dry partially before adding the next.

Finishing Touches

Once the plaster has dried, it can be sanded lightly to blend seamlessly with the surrounding wall. Because Hi-Lime is breathable, it’s an excellent base for finishing with breathable paints or lime washes.
