Vertical Drainage Systems - LowFlow™

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 Flow 15P shown below) can often value engineer by using a combination of Flow 15P in staggered chimneys, and Low Flow™ between the chimneys. Few site soil conditions require complete coverage with Flow 15P to obtain sufficient drainage.

Vertical Drainage Systems - Flow 15P

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

Horizontal Drainage System - Flow 18H and Flow 10HV

Polyguard Flow 18H Drainage and Protection System is a strong (18,000 lb/ft² compressive strength) "Dimple board" system for normal horizontal applications. Where higher compressive strength is required (up to 30,000 lb/ft²) Polyguard Flow 10HV Drainage and Protection System should be used.
