Basement Tanking Kent
Basement tanking is a Type A waterproofing solution that creates a barrier against water ingress. A waterproof slurry is applied directly to walls and floors to prevent moisture from entering the space. It is often used as part of a combined waterproofing system, alongside Type B or Type C waterproofing.
Basement waterproofing requires specialist knowledge to ensure lasting results. Our PCA-accredited team designs systems based on the structure, ground conditions and intended use of the space. We install basement tanking in Kent where appropriate, ensuring correct preparation and application to achieve a durable, watertight finish.
Type C Waterproofing Systems (Cavity Drainage)
For many properties, a cavity drainage system offers a more controlled and reliable solution. Type C waterproofing manages water ingress by directing it into a drainage system rather than holding it back. We install waterproof membranes to exterior walls and flooring, along with a sump pump to channel any water collected by the membrane system.
As trusted basement specialists in Kent, we provide clear recommendations and professionally installed solutions that meet industry standards. Our systems include cavity membranes, perimeter drainage channels and basement sump pump installation near Kent, safely removing water from the property and reducing pressure on the structure.
Choosing the Right Waterproofing System
Water ingress can lead to mould, damage to finishes and deterioration of structural elements. Addressing the issue early helps protect both your property and its value. The most effective solution depends on your property, the level of water ingress and how the space will be used. In some cases, a combination of systems may be recommended.
All designs follow BS8102 guidelines, ensuring your basement waterproofing in Kent is suitable for long-term use and compliant with industry best practice. Our approach focuses on long-term protection, ensuring your basement remains dry, safe and suitable for its intended use.
Whilst we often have same-week availability in Kent, it can be dependant on demand. Call 01233 356114 to speak to us and find the earliest survey appointment that works for you.
Yes. Proper diagnosis is essential to ensure the correct basement waterproofing course is applied and to avoid unnecessary work.
The best system depends on the property and level of water ingress. Type C cavity drainage systems are often preferred for their reliability, but tanking may be suitable in some cases.
Damp is usually caused by moisture entering the property or becoming trapped inside. Common causes of damp in basements include high groundwater levels (especially after heavy rain), high external water pressure, and leaks or other structural defects in your property.
REQUEST A SURVEY
If a cavity drainage system is installed, a sump pump is typically required to remove collected water safely from the property.
