ABSTRACT:
A waterproofing sheet used to waterproof structures above and below grade has a single layer of non-degradable, water impermeable polymeric membrane that has layers of particles of non-hydrated sodium montmorillonite (sodium bentonite) adhering to the membrane in a uniform layered thickness. The layers of particles of sodium montmorillonite spaced from the membrane adhere to each other, with a coating material (adhesive) that is designed to provide the necessary performance for waterproofing under a high water head (hydrostatic pressure). The material is in sectioned sheet or roll form and can be easily applied on the job.
