Basement Waterproofing & Structural Waterproofing


If you are considering adding an extra room to your home through a basement or cellar conversion, it is crucial to ensure proper waterproofing. We have encountered numerous instances of poor waterproofing installations that can be extremely costly and disastrous if they fail. With our expertise in damp and water management, we can assess and specify the appropriate Type A barrier or Type C water collection system in accordance with levels 1, 2, or 3 of the British Standard BS8102, which governs the protection of below-ground structures against water ingress.

Basement and structural waterproofing is a comprehensive process designed to protect below-ground areas and critical structural elements of a property from water ingress, damp and potential flooding. The process begins with a thorough inspection to identify sources of moisture, leaks, rising damp and any weaknesses in walls, floors or foundations. Once assessed, we develop a tailored solution that may include the installation of waterproof membranes, application of specialist sealants or coatings and where necessary, the implementation of drainage systems or sump pumps to manage water effectively.

Effective waterproofing not only prevents water from penetrating the building fabric but also safeguards timber, plaster and concrete from decay, rot and structural damage. It also reduces the risk of mould and mildew, improving indoor air quality and creating a safe, dry environment for occupants. For clients, this means peace of mind knowing that their property is protected from both immediate water issues and potential long-term structural problems, preserving the building’s integrity, usability and overall value. Our approach combines expert assessment, high-quality materials, and proven techniques to provide lasting, reliable protection tailored to each property’s unique needs.
