Code of practice for basement waterproofing

PCA issue new guidelines


Freephone :

A new code of practice relating to basement waterproofing systems has been drawn up by the Property Care Association (PCA).

The technical guide relates to drained cavity waterproofing systems - commonly known as type C waterproofing systems normally used within basement waterproofing.

When are type C basement waterproofing systems used

These waterproofing systems allow water to flow freely through a cavity between the exterior and interior walls of a basement, before it is channelled into a sump, from where it can safely be drained or pumped away.

Guidance for the Service and Maintenance of Drained Cavity Waterproofing systems (Type C) has been drawn up by the PCA's technical experts and highlights the need to undertake regular maintenance of these systems.

It also considers the need to design and install maintainable features and looks at the elements that should be examined and maintained.

Why the basement waterproofing guide has been created

The guide is a point of reference for PCA basement waterproofing contractors, as well as specific, homeowners, and property managers who install, control or own such waterproofing systems.

Steve Hodgson, deputy director of the PCA, said: "Type C basement waterproofing systems have developed rapidly over the last two decades and PCA contractors have access to some fantastic products.

"These include, high-density drainage membranes, advanced sealing and fixing systems, purpose designed perimeter drainage channels such as waterguard and state-of-the-art sump pumps.

Steve commented: "Most pumping systems now incorporate back-up pumps and batteries and an audible alarm - and it is even possible to install a system that will call people on their mobile phone if it detects a fault.

"However, the need to service and maintain the drainage elements of type C waterproofing systems is paramount to their long term success.

"This is already highlighted in BS8102, the Code of Practice for Protection of Structures Against Water From The Ground, and the PCA code of practice for ‘Remedial Waterproofing of Structures Below Ground' - as well as information from the distributors of products and equipment used to create waterproof basements.
