The bottom plate of Shandong Tianhai composite drainage and waterproof board is made of high-impact and high-compressive polyethylene (HIPS) and HDPE, which can withstand long-term high pressure without deformation. This long-lasting compressive strength not only bears the weight of the concrete slab and its load but also withstands inevitable external pressures and shocks during construction, such as vehicles, worker foot traffic, and the impact of concrete pouring. It maintains the bottom plate's shape over time, thus preserving the original drainage capacity. The filter layer geotextile on the bottom plate is designed to ensure that the drainage channel is not blocked by foreign materials, such as backfill soil particles or concrete.

Product Features:

The composite drainage and waterproof board integrates drainage and waterproofing, successfully addressing the relationship between waterproofing and drainage. It is superior and more reliable in terms of drainage functionality and economic benefits compared to traditional gravel, expanded clay drainage, and other filter layers. The composite drainage board combines waterproofing and drainage, enhancing the durability of the project; its performance lifespan reaches 120 years. Durability is a crucial aspect of waterproofing in construction, raising new and higher requirements for waterproofing issues. Theoretically, a waterproof system built with modern flexible waterproof materials can achieve complete impermeability, but these systems often suffer damage and can still experience leakage in the environment. The composite drainage board can divert this water, integrating waterproofing, drainage, interception, and blockage in the project, thereby meeting the new requirements of modern building waterproofing systems.

Application Scope:

It is widely used in rooftop gardens, outdoor garage green roofs, retaining walls, basements, tunnels, subways, underground foundation engineering, slope protection, and highway subgrade drainage and waterproofing.
