Drainage Board/Dimple Drain Sheet

Drainage Sheets, also known as Sheet Drain, are made of HDPE or Polypropylene drainage board and heat bonded with needle-punched filament nonwoven geotextiles. Drainage Sheets are widely applied for the drainage and filtration of retaining walls, basement walls, garden roofs, and plaza decks. What’s more, the Sheet Drain definitely fits the drainage of large surface areas which can be covered to provide maximum drainage capacities. Many drainage sheets can also be used for the protection of waterproofing materials, which can save the total cost of separate drainage boards’ usage.

The installation of a composite drainage board is an important step in ensuring proper water management and protection of structures. Here’s a general guide on how to install a composite drainage board: Materials and Tools Needed: Composite drainage board Adhesive or fasteners (depending on the manufacturer’s recommendation) Utility knife or scissors Measuring tape Chalk line or marker Shovel (for excavation, if necessary) Waterproofing membrane (if required) Protective gloves and safety gear Steps for Installation: 1、Prepare the Surface: Ensure the surface where the drainage board will be installed is clean, dry, and free of debris. If installing against a foundation wall, check for any cracks or damage that needs to be repaired. 2、Excavate the Area: If installing the drainage board around a foundation, excavate the soil around the foundation to the required depth. Ensure the excavation is wide enough to allow for easy installation of the drainage board. Apply Waterproofing Membrane (if required): Apply a waterproofing membrane to the foundation wall according to the manufacturer’s instructions. This step is crucial for preventing water infiltration. 3、Measure and Cut the Drainage Board: Measure the area where the drainage board will be installed. Use a utility knife or scissors to cut the drainage board to the appropriate size. 4、Install the Drainage Board: Position the drainage board against the wall or surface, starting at the bottom. Secure the drainage board in place using adhesive or fasteners as recommended by the manufacturer. Make sure the board is flush against the surface. Overlap the edges of the drainage boards if multiple pieces are used, following the manufacturer’s guidelines for overlapping. 5、Backfill the Excavated Area: Carefully backfill the excavated area with soil, ensuring the drainage board remains in place. Compact the soil as you backfill to avoid settling and maintain proper drainage. 6、Inspect and Finalize: Inspect the installation to ensure there are no gaps or areas where the drainage board is not properly secured. Make any necessary adjustments to ensure a tight fit and proper drainage. 7、Additional Tips: Always follow the specific instructions provided by the manufacturer of the composite drainage board. Wear protective gloves and safety gear during installation. Consider consulting with a professional if you are unsure about any part of the installation process.
