Identifying the Cause of Basement Leaks
Basements are particularly vulnerable to water ingress due to ground pressure and changing moisture levels. Water entering a basement can come from several sources, including groundwater pressure, poor drainage or structural defects. Identifying the cause is essential before selecting the right waterproofing system.
As experienced leaking basement specialists in Newcastle, we carry out detailed inspections to assess how water is entering the structure. This allows us to recommend a system that will perform effectively over the long term with a no-obligation quotation for any work we recommend.
Bespoke Basement Waterproofing Services in Newcastle
Every property is different, so basement waterproofing systems must be designed to suit the structure, the level of risk, and what you want to use the space for. The basement waterproofing services we offer in Newcastle include:
- Cementitious tanking systems to resist water ingress
- Cavity drainage membrane systems to manage and control water
- Sump pumps and drainage channels to safely remove water
- Combined waterproofing systems for enhanced protection
Each system is designed to be BS8102 compliant and in line with current best practice to ensure reliable performance.
Types of Basement Waterproofing Systems
Timberwise designs waterproofing systems in line with BS8102, selecting the right approach based on your property and risk of water ingress.
Type A systems, often called tanking, create a waterproof barrier on walls and floors to stop water from entering the structure. They can be effective where the building is sound and water pressure is controlled, but they rely on the barrier remaining intact.
Type C systems manage water rather than blocking it. A cavity membrane allows water to pass behind the system and be safely drained away via channels and sump pumps.
This is a flexible, maintainable solution and is commonly used where long-term reliability is essential.
Whilst we often have same-week availability in Newcastle, it can be dependent on demand. Call 0113 208 9146 to speak to us and find the earliest survey appointment that works for you.
Most surveys take between one and four hours, depending on the size of the property, the areas being inspected, and the extent of the damp problem.
Of course – no matter if you are in the dead centre of Newcastle, or outside the city entirely, our team are going to be able to help. We cover almost everywhere in the UK, so if you need a survey, just get in touch!

The best system depends on the structure and how water is entering the basement. In most cases, a combined system (for example, Type A and Type C waterproofing together) will be most effective. A professional survey ensures the correct system is selected for your property.
Sometimes. Tanking can be effective in some situations, but it is not always the most suitable solution. Alternative systems, such as cavity drainage, may be recommended as well as tanking to ensure your basement is protected properly.
A correctly designed and installed system can provide long-term protection, particularly when maintained appropriately. We offer a 10-year guarantee on completed basement waterproofing systems for added peace of mind.
