Drainage Composites

Reed & Graham, Inc. stocks a wide variety of drainage composites.  We represent two main manufacturers that produce different types of composite products.

American Wick Drain

American Wick Drain produces a vacuum formed dimple board that is covered with a geotextile filter fabric.  This board is normally installed vertically with the fabric side towards the earth and the flat side attached to the foundation.  There are a wide variety of applications and products depending on application.  Typical applications are foundation wall drains, retaining wall drains, and planter drains.  For other applications, please click on the following link:

Subsurface Drainage

Multiflow

Multiflow is manufactured of high density polyethylene material. Designed to replace standard French drains and other edge drain materials due to ability to intercept and collect high volumes of water and move it efficiently to drainage outlets. Multiflow may be installed either vertically or horizontally. This gives the designer greater flexibility where space and gradient may be a problem. Multiflow is generally used in three primary applications:

1. Soil Interceptor drains. This application is sports fields, golf courses, parks, lawns and other area where drainage is necessary.

2. Sheet drains. This application is the collection and movement of water away from foundation walls.

3. Highway edge drains. This application is used to remove water quickly away from the subsurface structure of a roadway. The quicker the water is removed, the longer the road structure will retain its design strength.

EZ Flow
Preassembled, lightweight EZ Flow units can be transported and installed by a single worker. They easily join together with an internal coupling to fit installation specifications precisely. The EZ Flow units may be used in conjunction with additional 10-foot lengths of EPS aggregate, without pipe, when additional drainage is needed.

EZ-Flow

Akwadrain
AKWADRAIN Strip drain is used where a water collection system is needed or full area drainage coverage is not necessary or practical. It can replace traditional pipe and stone for drainage collection systems. Typical applications are golf courses, athletic fields, and residential yards.
