DrainGuard 400

DrainGuard 400 is a dimple board drainage composite.  It is a two part groundwater drainage material.  Dimpled high density polypropylene core with a non-woven geotextile filter fabric attached.  The non-woven filter fabric retains soil or sand particles, allowing water to pass to the drainage core.  The void allows groundwater to flow down vertically to the collection pipe.  Also protects waterproofing membranes from damage.
