Geocomposite Sheet Drain

In modern construction, effective waterproofing and subsurface drainage are critical to the structural longevity and safety of buildings. Among the most reliable materials for this purpose is the Dimpled Drainage Board Drainage Sheets—an innovative solution engineered to provide superior water diversion, air ventilation, and protection for underground structures and green roofs.

Whether used in residential basements, commercial foundations, or rooftop landscapes, Dimpled Drainage Board Drainage Sheets deliver unmatched performance and durability in moisture management systems.

What Are Dimpled Drainage Board Drainage Sheets?

Dimpled Drainage Board Drainage Sheets are high-density polyethylene (HDPE) or polypropylene (PP) panels featuring a raised dimple structure. These dimples create a continuous air and water drainage space between the waterproofing membrane and backfill soil, ensuring long-lasting protection from hydrostatic pressure and moisture buildup.

Available in rolls or sheet form, Dimpled Drainage Board Drainage Sheets are installed vertically or horizontally against retaining walls, under slabs, or beneath green roofs to facilitate free water flow and surface protection.

Top Benefits of Dimpled Drainage Board Drainage Sheets

1. Superior Subsurface Drainage

The primary function of Dimpled Drainage Board Drainage Sheets is to provide a dedicated drainage channel. Rainwater, groundwater, or irrigation runoff is quickly directed away from structural walls, preventing water seepage and erosion.

2. Protection of Waterproofing Layers

Acting as a protective barrier, Dimpled Drainage Board Drainage Sheets shield waterproof membranes from mechanical damage during backfilling and ground settlement. This extends the life of your waterproofing system significantly.

3. Ventilation and Pressure Relief

The air gap created by the dimples allows vapor to escape, reducing condensation risks and pressure buildup. This is particularly crucial in below-grade applications and planter boxes.

4. Easy Installation and High Load Capacity

These sheets are lightweight, flexible, and easy to install using adhesive or mechanical fasteners. Despite their low profile, Dimpled Drainage Board Drainage Sheets offer exceptional compressive strength, often exceeding 250 kN/m², making them suitable for high-load applications.

5. Environmental and Cost Efficiency

Made from recycled and recyclable HDPE, Dimpled Drainage Board Drainage Sheets are environmentally responsible and reduce long-term maintenance costs by preventing structural water damage.

Common Applications of Dimpled Drainage Board Drainage Sheets

Thanks to their versatility, Dimpled Drainage Board Drainage Sheets are widely used in:

• Basement walls and retaining walls

• Foundation slabs and underground garages

• Tunnel linings and bridge decks

• Green roofs and landscape drainage

• Podium decks and terrace gardens

• Elevator pits and wet areas

These sheets can be paired with geotextile fabric to create a composite drainage system that filters soil and debris while promoting water flow.
