Continuing from my previous blog and the question of design, I look at considerations for ensuring an effective waterproofing solution. 

Combined meetings with architects, engineers, geo-technicians, contractors, and in the case of waterproofing — a good technical advisor, provide the knowledge to prevent excessive design alterations after construction has commenced.

There is no aspect of bentonite waterproofing that is as misunderstood as how it responds to wet/dry cycling.

Below-grade shoring wall construction often proves to be difficult to obtain and maintain along the project site perimeter. 

A detailed discussion of the water/soil compatibility test and its importance in the design of any below-grade waterproofing system.

This month I look at the provision of containment pressure to maintain the effectiveness of bentonite tanking membranes under both static and seismic conditions. 

Mitigating the risk of over-hydration is key to the success of a bentonite membrane — especially in wet conditions.
