Polyguard's waterproofing products have been used for waterproofing ICF foundations since ICF first became popular. Most ICF manufacturers recommended Polyguard's waterproofing membranes as one of the most foolproof methods of protecting from below grade leakage.

A series of ICF waterproofing photos (residential construction and retaining wall construction) are shown on the ICF Builders' Network website (www.icfhomes.com/PhotoPages/photo_waterproof.htm)

Polyguard Products has developed several products specific to the needs of the ICF industry. The Underseal products were developed as a combination waterproofing membrane and termite barrier in response to requests by the ICF industry.

650 Waterproofing Membrane

Polyguard 650 Membrane is the most recommended waterproofing systems for ICF below grade applications.

The primary use of Polyguard Underseal Membranes are for concrete foundation waterproofing and/or for protection from termite intrusion. The membrane can be applied directly to concrete, or to insulated concrete form (ICF) foundations.

Other applications include mud slabs, related applications where waterproofing is critical, and termite remediation (protecting cracks and crevices from termite intrusion).

Polyguard Underseal Membranes are strong, pliable, self adhering sheet membranes consisting of a triple thickness polyethylene backing laminated to an extra thick layer of rubberized asphalt.Underseal Membranes adhere tightly and permanently to concrete. The polyethylene sheet forms a continuous barrier impervious to water. The adhered rubberized asphalt prevents lateral migration of any water which might find its way behind the sheet. Total membrane thickness is factory controlled.

Underseal Protected Wall Waterproofing Membrane with Built in Protection Board

Polyguard Waterproofing Membrane has the added feature of a 500% extra thickness backing. This extra thickness backing eliminates the need for a separate protection board system on flat vertical surfaces. Overall thickness is 65 mils.

Available in 39.36" x 61' rolls, 200 sq. ft. per carton.

Low Flow™

Polyguard LowFlow - Drainage and Protection Mat is a green (100% post industrial recycled content) which offers two attractive approaches to drainage. For a full description of the development of LowFlow™, click here.

1. Since Low Flow costs about the same as widely used protection systems, specifiers can have drainage capability for approximately the same cost as a vertical protection system alone.
2. Specifiers who have called for full-wall coverage of conventional drainage systems (such as Polyguard PolyFlow 15P shown below) can often value engineer by using a combination of PolyFlow 15P in staggered chimneys, and Low Flow between the chimneys. Few site soil conditions require complete coverage with PolyFlow 15P to obtain sufficient drainage.

PolyFlow 15-P and 18-H

Vertical Drainage System - PolyFlow 15P
Polyguard PolyFlow 15P Drainage and Protection System is a conventional "dimple board" drainage system with a built-in protection layer.

Horizontal Drainage System - PolyFlow 18H
Polyguard PolyFlow 18H Drainage and Protection System is a strong (18,000 lb/ft2 compressive strength) "Dimple board" system for normal horizontal applications.

Polyguard is ISO 9001 certified since 1996.
