Hydrodrain® - Drainage Solutions
Water management is a critical issue in the design and construction of a structure. Without proper drainage, severe structural damage could occur. In below grade structures, proper drainage will reduce hydrostatic pressure by channeling water away from the structure. For horizontal applications, in particular dead level or low slope structures, proper drainage can provide an avenue for the water to flow to the drains between the membrane and topping materials. For between slab applications, it can decrease the risk of possible freeze thaw damage to the wearing surface.
Millions of square feet of Hydrodrain and Thermaflo drainage composites have been specified by architects and engineers nationwide for over 25 years. Hydrotech offers a wide variety of cost effective, state-of-the-art drainage media. Typical uses include plaza decks, roof gardens, planters, retaining walls, and foundation walls.
Hydrodrain 300, 302, 1000 and AL are composite drainage products consisting of a three-dimensional geonet, crush-proof drainage core and a non-woven, needle punched filter fabric. There are several variations of this product to meet particular project requirements. These products are acceptable in both horizontal and vertical applications, but are considered ideal in horizontal installations where a high compressive strength is desired.
Hydrodrain 400, 420, 700 and 990 are composite drainage products consisting of three-dimensional "dimple" type polyethylene core with a non-woven, filter fabric (Hydrodrain 400 and 420 are needle punched). There are several variations of this product to meet particular project requirements. These products are acceptable in both horizontal and vertical applications, but are typically used in vertical installations (foundation walls, planters, etc.) where it's high flow rate is a plus.
