Project Description


If you have an existing basement or are considering creating a new below-ground structure then the specialist design and installation team at APP can assist you with all aspects of the structural waterproofing. Working together with Architects, Engineers and Main Contractors to develop the project from inception through to installation. Basement projects that APP have been involved with in the past have been used for gyms, home cinemas, utility rooms, wine cellars, as well as commercial kitchens and server rooms.


The process for ensuring that below ground structures remain dry can be a complicated one – the British standard for waterproofing below ground structures, BS8102:2009, gives recommendations and provides guidance on methods of dealing with and preventing the entry of water from surrounding ground into a structure below ground level. 

At APP we are fully qualified to design, supply and install structural waterproofing systems in accordance with BS 8102:2009. Our surveyors are CSSW qualified and listed on the PCA Waterproofing Design Specialist Register and our operatives hold the PCA technicians qualifications. 


With the cost of housing and land increasing the conversion and construction of basements is becoming more fashionable, adding space and market value to properties. However, if things go wrong and projects fail then costs can be extremely high. Therefore, it is so important to get the correct expertise at the earliest point in the design stage of any project.

APP can work with Architects, Engineers and Main Contractors as part of the design team to provide a suitable waterproofing solution to these below ground areas, to suit individual requirements.


Our surveyors are qualified to Certificated Surveyor of Timber & Dampness in Buildings (CSTDB) and Certificated Surveyor in Structural Waterproofing (CSSW) standard. This is the industry standard accreditation administered by the Property Care Association.
