Basement Tanking

While there are many different kinds of basement tanking, we here at London Damp Specialists mainly work we two types:

Cavity Drainage Sump and Pump:

This method involves fitting a textured membrane to the basement's walls, floor, and ceiling, and then covering the entire construction with specialist plasterboard, insulation, and screed. A hidden pump is installed to manage and direct water out of the system into the normal water table or wastewater source. This approach allows water to penetrate in a strictly managed and controlled way, leaving you with a completely dry inner room that can be finished and decorated as desired. The cavity drainage approach is noted for its excellent results and simplicity in maintenance and repair.

Cementitious Tanking:

This involves applying a cement-based waterproof coating to the interior surfaces of the basement. It creates a barrier that prevents water from penetrating the walls and floor.

Costs for basement tanking starts at £195 +vat per square metre

Ignoring a leaking basement can lead to several risks and problems, both in the short term and long term:

Structural Damage: Continuous water leakage can weaken the foundation and walls, leading to cracks and potential structural failure over time.

Mould and Mildew Growth: A damp environment is a breeding ground for mould and mildew, which can spread throughout the property, leading to unpleasant odours and potential health risks.

Damage to Property: Water can damage furniture, appliances, and stored items in the basement, leading to costly replacements and repairs.

Decreased Property Value: A leaking basement can significantly reduce the value of a property, making it less appealing to potential buyers.

Electrical Hazards: Water intrusion near electrical systems can create a risk of electrical shock or fire.

Poor Air Quality: The growth of mould and mildew can lead to poor indoor air quality, potentially causing respiratory issues and other health problems for occupants.

Increased Utility Costs: A damp basement may require more heating or cooling to maintain a comfortable temperature, leading to higher energy bills.

Pest Infestations: The damp environment may attract pests like insects and rodents, leading to infestations that can spread to other parts of the property.

Aesthetic Issues: Water stains, peeling paint, and other visible signs of water damage can create an unattractive appearance in the basement area.

Legal Issues: In some jurisdictions, failure to address known water leakage issues may lead to legal liabilities, especially if you're selling the property or renting it out.

When you contact us, you can schedule a free, no-obligation damp survey that takes just 15 to 30 minutes. Afterwards, we'll begin our specialised basement tanking process.

Based on our survey of your basement area, we will either do a cavity drainage sump and pump or a tanking and rendering system.

And to ensure your peace of mind, we offer a no-quibble 30-year guarantee at no extra cost. Trust us to handle your basement tanking with efficiency and expertise.

Yes, it can.

Well, that depends entirely on how well the basement tanking was done and the type of tanking as well. That said, we offer a 30-year guarantee with a 10-year insurance-backed guarantee.

Yes, basement tanking is generally considered a long-term solution for preventing moisture issues in basements. When done correctly, it creates a barrier that stops water from entering the basement, effectively keeping the space dry and free from damp-related problems. Here's why basement tanking is seen as a long-term solution:

Effective Barrier: Basement tanking methods create a waterproof barrier that blocks moisture from entering the space, addressing the root cause of the problem.

Durable Materials: Many tanking methods use materials specifically designed to withstand moisture and the pressures exerted by the surrounding soil, ensuring long-lasting protection.

Professional Installation: When installed by professionals with expertise in basement tanking, the system is more likely to be effective and long-lasting. The proper installation considers the unique characteristics of the property and ensures that the system is tailored to those needs.

Regular Maintenance: With regular inspections and maintenance, any minor issues can be identified and addressed before they become major problems, further extending the lifespan of the tanking system.

Warranties and Guarantees: Many professional installers offer extended warranties or guarantees, reflecting confidence in the long-term effectiveness of the system. For example, London Damp Specialists offer a 30-year guarantee on their Cavity Drainage Sump and Pump method.

Versatility: Different tanking methods can be used to suit various types of construction, soil conditions, and moisture levels, allowing for a customised approach that addresses the specific needs of the property.

Enhanced Property Value: By providing a long-term solution to moisture issues, basement tanking can enhance the value and usability of the property, turning a previously damp space into a functional and appealing part of the home.

While basement tanking is generally effective, it's essential to choose the right method and professional installer for the specific situation. Proper assessment, installation, and maintenance are key to ensuring that basement tanking serves as a long-term solution for preventing moisture issues in basements.

Well, sort of. All cellar tanking and basement waterproofing systems are created by removing all damaged plasterwork and damaged masonry, and stripping your basement back to its original building material. Then the foundation layer is cleaned and prepared for the tanking process. Following this we offer our clients the choice between cavity drainage sump and pump system or tanking and rendering system. But, having said that, we do make the necessary adjustments to the plan depending on the type of basement and the conditions of the project.

Detecting a leaky basement can often be done by observing specific signs and symptoms. Here's what to look for:

Water Puddles or Pooling: Finding standing water or puddles on the floor is a clear indication of a leak.

Damp or Wet Spots: Wet spots on the walls, floors, or ceiling can signal a leak, especially if they appear after rain or snowmelt.

Mould and Mildew Growth: The presence of mould or mildew, often accompanied by a musty odour, can indicate persistent dampness due to a leak.

Water Stains: Discoloration or water stains on walls, floors, or ceilings can be a sign of water seepage.

Peeling Paint or Wallpaper: If paint or wallpaper is peeling or bubbling, it may be due to moisture getting behind it.

Cracks in Walls or Floors: Cracks can allow water to enter the basement, especially if they widen over time.

Efflorescence: A white, chalky substance on walls or floors is a sign of mineral deposits left behind by evaporating water.

Rust on Metal Surfaces: Rust on metal objects or fixtures in the basement can indicate ongoing moisture issues.

Swollen or Warped Wood: Wooden doors, windows, or beams that appear swollen or warped may be absorbing moisture from a leak.

High Humidity: A consistently high level of humidity in the basement may be a sign of a slow or minor leak.

Increased Utility Bills: An unexpected increase in water bills might indicate a hidden leak.

Sounds of Running Water: Sometimes, you might hear the sound of running or dripping water, even if you can't see the source.
