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 20 years. Hydrotech offers a wide variety of cost effective, state-of-the-art drainage mediums. 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 (Hydrodrain 300). 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 and 700 are composite drainage products consisting of three-dimensional "dimple" type polyethylene core with a non-woven, needle punched filter fabric (Hydrodrain 400). 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. |

Thermaflo combines the excellent thermal protection of STYROFOAM® insulation, superior drainage capability and protection to the waterproofing membrane - all in a single product. This 3 in 1, multi-purpose product is particularly well suited to below grade vertical foundation walls.
The advantage of Thermaflo on a foundation wall is that it cuts labor in half, when compared to the installation of a separate protection layer and drainage composite. The thermal protection is an added benefit. |
