Containment Grid
The Exceptional “Peace of Mind” System
The Grid System offers a unique “containment grid” feature that reduces the risk of expensive removal and replacement of overburden. As the name implies, the area to be waterproofed is marked out in a grid pattern, with each section becoming its own individual containment field. This is accomplished by adhering strips of membrane around the perimeter of each grid section to act as a sub membrane waterstop. Should a leak occur in the future, the containment grid isolates the water, eliminating any potential spread from one section to another.

The Grid System was used to waterproof the plaza area of the John F. Kennedy Library in Boston, Massachusetts. Because of the irreplaceable artifacts and documents located directly beneath it, the owners wanted absolute system integrity and maximum watertight security. For this reason, the consulting engineers specified Sika Sarnafil’s high performance Grid System. |
