Drainage Board

The base plate of the anti-drainage board is made of high-impact and high-pressure resistant polystyrene (HIPS) or HDPE that can resist long-term high pressure without deformation.

Product Overview

The base plate of the anti-drainage board is made of high-impact and high-pressure resistant polystyrene (HIPS) or HDPE that can resist long-term high pressure without deformation. This long-term compression resistance can not only withstand the weight of the concrete slab and its load, and can withstand the unavoidable external pressures and impacts during the construction period, such as vehicles, workers trampling and concrete filling force. Long-term maintenance of the bottom plate does not deform, and therefore can maintain the original drainage. The purpose of the filter geotextile on the sub-slab is to ensure that the drainage channels are not blocked by foreign objects, such as backfill particles or concrete.

Product Features

Anti-drainage board set anti-drainage in one, successfully solved the relationship between waterproofing and drainage, no matter in the drainage function, economic benefits than the traditional stone ceramic grain drainage and other filtration layer is superior and reliable. Anti-drainage board is a new product that combines waterproofing and drainage and increases the durability of the project. An important part of the building structure anti-drainage is durability, which puts forward new and higher requirements for the construction of anti-drainage problems, the use of modern flexible waterproofing materials constructed waterproofing system, theoretically able to do completely impermeable, but the waterproofing system will often be damaged, in the environment will still produce seepage, composite anti-drainage board can be part of the water channeling drainage, so that the project anti-drainage in the defense, drainage, interception, plugging combination, to achieve the modern construction of anti-drainage. The combination of prevention, discharge, interception, blocking, to achieve the new requirements of the modern building drainage prevention system.

The top surface of the conical protruding platform is glued with a layer of filtering geotextile to prevent soil particles from passing through, so as to avoid the blockage of the drainage channel to make the aperture drain smoothly. The traditional drainage method uses masonry tiles as the filtering layer, more cobbles or gravel as the water filtering layer, and drains the water to the designated place. Now the drainage board instead of cobblestone filter layer to drain the time, effort and energy saving, saving investment, but also can reduce the load of the building.

Good drainage system has an important role in the construction cycle of civil engineering and the normal use and life of the building. HW type drainage board and porous water seepage pipe form an effective drainage system, cylindrical multi-hollow drainage board and geotextile also form a drainage system, so as to form a system with seepage, water storage and drainage functions.

Application range of anti-drainage board

It is widely used in roof gardens, greening of outdoor garage roofs, retaining walls, basements, tunnels, subways, subway foundation works, slope protection, and anti-drainage of highway roadbeds.
