What is the Basement & Cellar Tanking Process?
1. Initial Survey
Every basement tanking project begins with a detailed survey of the property. Our specialists assess the structure, identify sources of damp and water ingress, and determine the most suitable waterproofing solution. This helps us recommend the right basement tanking system based on the property's condition and intended use.
2. Surface Preparation
Before tanking can be installed, basement walls and floors must be properly prepared. Any damaged plaster, loose materials or existing coatings are removed to create a suitable surface. Careful preparation is essential for achieving a strong bond and long-lasting waterproof protection.
3. Basement Tanking Installation
Once preparation is complete, the selected basement tanking system is applied to vulnerable walls and floors. This creates a waterproof barrier that helps prevent moisture from entering the space. The installation process is tailored to each property, helping deliver effective protection against damp and water ingress.
4. Long-Term Protection
After installation, the tanking system provides ongoing protection against moisture, helping keep the basement dry and usable throughout the year. Additional drainage or ventilation measures may be recommended where necessary. The result is a safer, healthier space that is better suited for storage, living accommodation or future basement conversion projects.
Professional Basement Tanking for Dry, Protected Spaces
Basements and cellars are naturally prone to damp, water ingress and condensation. Without the right protection, below-ground rooms can become cold, musty and difficult to use.
Home Energy Save GB provides professional basement tanking services to help protect walls, floors and below-ground spaces from moisture. Whether you are dealing with signs of damp or planning a full basement conversion, our experienced team can assess your property and recommend the right waterproofing solution.
Signs Your Basement May Need Tanking
Damp Patches
Persistent damp patches on basement walls or floors are often one of the first signs that moisture is entering the structure. These areas may appear darker, feel cold to the touch or worsen after periods of rainfall.
If left untreated, damp can damage plaster, decorations and stored belongings while creating conditions that allow moisture problems to spread throughout the space.
Mould & Musty Odours
Musty smells and visible mould growth are common indicators of excess moisture within a basement or cellar. These issues often develop when water ingress combines with poor ventilation and high humidity levels.
Over time, mould can affect air quality and damage surfaces, making the space less comfortable and suitable for everyday use or future conversion projects.

Frequently Asked Questions
How long does basement tanking last?
A professionally installed basement tanking system is designed to provide long-term protection against damp and water ingress. The lifespan of the system will depend on factors such as the type of waterproofing used, the condition of the property and whether any drainage measures are required. When installed correctly and maintained where necessary, basement tanking can help keep below-ground spaces dry and protected for many years.
Does basement tanking stop damp and mould?
Basement tanking is designed to prevent moisture from penetrating walls and floors, helping to tackle one of the main causes of damp and mould growth. By creating a waterproof barrier, tanking helps reduce excess moisture levels within the basement or cellar. This can result in a drier environment, fewer musty odours and a reduced risk of mould developing on surfaces and stored belongings.
Can a tanked basement be converted into a living space?
Yes, many homeowners choose to waterproof their basement before converting it into a usable room. A properly tanked basement provides a dry and protected environment that is more suitable for uses such as home offices, gyms, bedrooms, playrooms and entertainment spaces. Waterproofing is often one of the most important stages of preparing a basement for long-term occupation.
How do I know if my basement needs tanking?
There are several signs that may indicate a basement or cellar requires waterproofing. Common issues include damp patches, peeling paint, mould growth, musty smells, water stains and visible signs of water ingress after periods of rainfall. If you notice any of these problems, a professional survey can help identify the source of moisture and determine whether basement tanking is the most suitable solution.
Is basement tanking suitable for older properties?
Yes, basement tanking can be an effective waterproofing solution for both modern and older properties. Many older homes have cellars or basements that were not originally designed for regular use and may be more susceptible to damp and water ingress. Following a detailed assessment, the most appropriate tanking system can be selected to suit the property’s construction and condition.
