Pressure Seal Waterproofing

Drainage Systems

Aggregate-Free Drainage System
An important yet often overlooked part of the complete waterproofing system is providing proper water drainage. This system offers eleven specific drainage solutions to meet virtually any project's requirements. These drains provide the channel for water migration, relieves hydrostatic pressure and protects the waterproofing system. This system also replaces the excessive weight of a traditional aggregate drainage system, reducing higher shipping weight and cost.

Typical Uses
Prefabricated drainage panels may be installed in a variety of construction applications, such as against retaining walls and foundation walls (both waterproofed and non-waterproofed). The panels can terminate at the top of the footing and are flexible enough to form right angles to cover the top of the footing. This system eliminates the need for a protective course over waterproofing systems.
