Paraseal is a self-sealing sheet waterproofing membrane manufactured to controlled thicknesses of 150 mils to 200 mils of tough, high density polyethylene (HDPE) and expandable 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 your project is deep enough in the ground to get into the water-table we can help.

There are two approaches to solving water table issues on your project

• Mechanical pumping (Sump pump)
• Waterproofing Underslab

Mechanical pumping will be a maintenance cost and will only function if there is power to keep the motor running. It may be a less expensive approach up front but need to be maintained and replaced from time to time to ensure water free space in high water areas. Some pumps can be purchased with a backup battery and others with an alarm if pump needs to be replaced. TALK TO A PLUMBER OR EXCAVATOR NEAR YOU IF THIS IS THE SOLUTION YOU NEED.

Waterproofing underslab on the other had is a single purchase. If designed properly with the aid of an engineer, waterproofing can block water entry even in the most extreme cases from entering the home from under your floor. This does not mean you can stop maintaining the slope away from the home and route all water from the roof to the basement, but it does offer a manufacturer and installer warranty against water entry to keep your space free from water intrusion.
