Introduction
The Secure System for Structural Waterproofing
RAWMAT® HDB is used on major projects all over the world to provide secure and high quality structural waterproofing.
This unique system of pre-hydrated natural sodium bentonite has been carefully developed to overcome the inherent disadvantages of dry bentonite and other waterproofing systems.
RAWMAT® HDB acts as a barrier to the passage of water, vapour and gases providing Grade 4 protection for Type A structures in line with BS8102:1990.

It is ideal for overcoming difficult ground conditions or arduous design criteria and has been extensively tested to guarantee waterproofing of the structure for the life of the building, benefits which are ideal for PFI and Design & Build projects.
This high quality solution ensures the best of both worlds. Specifiers can rely on simple detailing which is easy to specify into a variety of waterproofing applications, while contractors value the time and money saved in installation and the ability to self-heal minor puncturing due to the ‘active’ nature of the system.
The ultimate winner is the client who benefits from a most cost competitive and high performance design to satisfy their waterproofing needs.
