How Tanking Protects a Basement from Unexpected Flooding Risks
For those who have a basement in their properties, they are naturally prone to the risk of water damage, due to their below ground location. Without proper waterproofing, basements are highly susceptible to flooding and water damage, as moisture can penetrate walls, causing damp, mould, and structural problems.
Basement tanking is an effective solution, creating a protective barrier to keep a basement dry and shielded from water ingress. At Kenwood PLC, we offer professional basement tanking treatments across London and the South East. In this post, we’ll explore what tanking is, how it protects a basement from unexpected water damage, and discuss the costs involved.
Understanding the Risks of Water Damage in Basements
Basements are at a high risk of water damage as they are located below ground level in properties. Surrounded by soil, they are constantly exposed to rainwater runoff, groundwater, and rising water tables, making them particularly vulnerable to damp and flooding. Cracks in the walls, poor drainage, and ineffective waterproofing can all contribute to moisture seeping in, leading to serious long-term issues.
If left untreated, water damage can compromise the structural integrity of your home, create an unhealthy living environment, and result in costly repairs. Understanding these risks is crucial to protecting a basement and maintaining a safe, dry home. Below we discuss three common water related issues in basements that have not had tanking systems installed.
Flooding – Basements are highly susceptible to flooding due to heavy rain, rising groundwater, and poor drainage. Water can enter through cracks in the walls or floor, causing significant damage to flooring, furniture, and stored items. Persistent flooding can weaken the building’s foundation, leading to costly structural repairs.
Damp and Mould Growth – Excess moisture in basements creates the perfect conditions for damp and mould growth. This can result in musty odours, unsightly black patches on walls, and even damage to plaster and paint. Mould spores can also affect indoor air quality, triggering allergies and respiratory issues for those living in the home.
Condensation and High Humidity – Poor ventilation and naturally cool temperatures also make basements prone to condensation and high humidity. This can lead to damp surfaces, peeling wallpaper, and warped wooden fixtures. Excessive moisture encourages mould and mildew, damaging stored belongings and creating an uncomfortable, unhealthy environment that affects the rest of the home.
Basement Tanking: What is it and How Can it Help?
Basement tanking is an effective waterproofing method that helps protect a basement from the risk of water damage. It creates a protective barrier that prevents water from seeping into basement walls and floors, offering a proven solution to keep basements dry and usable, even in high risk areas.
At Kenwood PLC, we offer a range of basement tanking systems that are highly effective for waterproofing below ground structures. These include our own Kenwood SWS tanking system, Kenwood Rapid, or a Cavity Drain Membrane System. We assess your basement to determine the most suitable method of tanking for their properties, providing tailored solutions to meet specific needs. Below we outline just some of the benefits of basement tanking systems:
Prevents Flooding and Damp
Basement tanking provides a strong waterproof barrier, stopping water from seeping through walls and floors. This prevents common moisture related issues such as damp patches, mould growth, and water ingress. By keeping a basement dry, it helps improve air quality, reduces maintenance costs, and protects belongings, ensuring your home remains safe and damp free.
Protects the Structural Integrity of a Home
Water damage can weaken foundations, leading to cracks, subsidence, and long term structural problems. Basement tanking prevents moisture from penetrating walls, helping to maintain the stability of your property. By keeping the structure dry, it reduces the risk of decay, damp related deterioration, and costly repairs, ultimately ensuring your home remains strong, secure, and structurally sound.
Adds Usable Space and Value to a Property
A waterproofed basement remains dry, making it suitable for extra storage or conversion into a usable living space. Whether transformed into an office, gym, or additional room, a tanked basement enhances your home’s functionality. It also increases property value, as buyers see it as a well-maintained, protected, and practical extension of the home.

How Much Does Basement Tanking Cost?
The cost of basement tanking varies depending on some key factors, including the size and condition of the basement, the extent of existing water damage, and the type of tanking system used.
