Used in conjunction with well compacted concrete, a bentonite membrane can provide a robust waterproofing protection system which is straight forward to install, self-repairing, and easy to repair or patch, prior to pouring concrete. They are cost-effective options and accepted by NHBC and other leading insurers as an acceptable line of waterproofing defence.
Bentonite membranes are simple to install and can be installed in most temperatures and weather conditions. If damaged during installation, for example by steel reinforcement piercing the membrane during steel installation, they can be patched and repaired using the same material that will already be on site. Punctures in bentonite membrane will often self-heal or can be enhanced by adding some bentonite powder (available as an accessory) with a little water added to form a repair paste.
