Paraseal Bentonite Membrane

Check up to five results to perform an action.

Paraseal is a sheet waterproofing membrane manufactured to controlled thicknesses of 150 mils to 200 mils of tough, high density polyethylene (HDPE) and expandable, quality granular Bentonite. The Bentonite, capable of expanding up to 8 times its thickness, is laminated at a rate of up to one pound per square foot to the impermeable HDPE sheet forming a superior Dual Waterproofing System for application to vertical and horizontal surfaces.

Basic Uses:
Paraseal is a waterproofing membrane designed for use on structures below grade or between slab. It is excellent for use on poured and block foundation walls, split slab parking and plaza decks. It has outstanding performance when used under conditions of high water head and installed prior to the concrete pour such as retaining walls, elevator pits, etc.


If groundwater is brackish, SALTWATER Grade Paraseal may be required. Paraseal products require compaction/confinement to be effective. A minimum 24 psf confinement is required. In lagging situations, Paraseal LG (Lagging-Grade) is required. In situations where methane or continual submersion may occur,
Paraseal W/GM (Waterproofing/Gas-Membrane) is required. Contact your local representative or technical services for more information.

Also available by Special Order:
  • Larger size rolls may be customized for a nominal cutting charge.
