The base plate of Shandong Tianhai composite drainage board is made of high-impact and high-compression resistant polyethylene (HIPS) and HDPE, capable of withstanding long-term high pressure without deformation. This long-term compressive strength can withstand the weight of the concrete base plate and its loads, as well as the unavoidable external pressures and impacts during construction, such as vehicles, pedestrian traffic, and the impact of concrete pouring. It maintains the base plate shape over time, thus preserving the original drainage capacity. The filter layer geotextile on the base plate is designed to ensure that the drainage channel does not become blocked by foreign materials, such as backfill soil particles or concrete.

Product Features:

  The composite drainage board integrates drainage and waterproofing, successfully resolving the relationship between waterproofing and drainage. In terms of drainage functionality and economic benefits, it is superior and more reliable than traditional stone and expanded clay drainage and other filter layers. The composite drainage board is a new product that combines waterproofing and drainage, increasing the durability of the project, with a performance aging period of up to 120 years. Durability is a crucial aspect of the drainage system in building structures, which raises new and higher requirements for drainage issues in construction. The waterproof system constructed with modern flexible waterproof materials can theoretically achieve complete impermeability; however, the waterproof system is often damaged, leading to leakage in the environment. The composite drainage board can channel and drain this portion of water, integrating the functions of drainage, blocking, and sealing within the engineering drainage, meeting the new requirements for modern building drainage systems.

Application Range:

  It is widely used in rooftop gardens, outdoor garage greening, retaining walls, basements, tunnels, subways, underground foundation projects, slope protection, and highway embankment drainage.
