RAWMAT® HDB membranes offer unparalleled resistance to contamination and as such are suited to a wide variety of petrochemical lining applications. This unique system of pre-hydrated natural sodium bentonite gives truly long-term effectiveness and reliability, which is assured by Rawell's emphasis on rigourous, ongoing, life-time testing of its materials with a wide variety of permeants.
Tank farms are readily and securely bunded (concrete and earth) with RAWMAT® HDB, which can be installed in most weather conditions. Manufactured in a Quality-Assured, controlled environment, RAWMAT® HDB's pre-hydration means that it can be installed onto a formation which has been subject to a hydrocarbon spillage, and the costly removal of contaminated material prior to the installation of the membrane is not necessary if RAWMAT® HDB is used. Furthermore, contaminated material which may have been removed from the existing formation can be used to confine the membrane. RAWMAT® HDB's pre-hydration negates the need to hydrate on-site, further reducing the time required to install.
The advantages of RAWMAT® HDB do not end with its' installation, as RAWMAT® HDB's long-term performance means that periodic flooding of the bund (required by 'dry' bentonite systems) is not required.
This unique solution ensures the best of both worlds. Specifiers can rely on flexible and proven long-term solutions to range of petrochemical lining problems, while contractors value the time and money saved in transport and installation as well as the ability to self-heal minor puncturing.
The ultimate winner is the client, who benefits from the highest quality solution at a competitive price - and with shorter programmes than any other system, offering huge cost advantages.
