Polymer Waterproof Material Series-Drainage Board

Product Presentatio 
The drainage board is made of high-density polyethylene (HDPE) plastic board extruded into a conical protrusion (or hollow cylindrical porous), and the top surface of the conical protrusion is bonded with a layer of filtering geotextile to prevent soil particles from passing through, thereby avoiding blockage of the drainage channel and ensuring smooth drainage of the channel. The traditional drainage method uses bricks and tiles as the filter layer, and more pebbles or crushed stones as the filter layer to discharge water to designated locations. However, now using drainage boards instead of pebble filter layers for drainage saves time, effort, energy, investment, and can also reduce the load on buildings.
Drainage board, also known as drainage board, drainage board, plastic convex sheet, waterproof and drainage protection board, plastic drainage board, plastic drainage (storage) board, sandwich plastic board, plastic drainage convex sheet, etc.

Manufacturing Process
The drainage board is made of high-density polyethylene film produced by extrusion method, which is extruded and sealed with protruding circular, cylindrical, and spherical shells to form a continuous film and shell, with three-dimensional space and certain support stiffness. It is a board material in which liquids and gases can flow and be discharged.

Scope of Application
Landscape engineering: planting of underground garage roof, greening of floor roofs, football fields, golf courses, bathhouses, planting in saline alkali land, etc.
Construction engineering: anti-seepage at the basement floor level, anti-seepage at the upper and lower levels of the building foundation, and anti-seepage at the basement interior and exterior wall levels.
Transportation engineering: tunnels, highways, railway embankments, dams, slope protection and drainage.
Municipal engineering: subway, road subgrade, landfill.
Decoration project: moisture-proof, partition, shock absorption, wiring.

Product Advantages and Features
Environmental Protection: Using reliable HDPE environmentally friendly materials, it will not cause pollution to the ecological environment.
Drainage: The large clearance space and vertical design of the product's convex platform ensure the rapid outflow of water flow, and the drainage capacity is much better than traditional pebbles and ceramic particles, without stagnant water, thereby reducing leakage hazards.
Pressure resistance: patented reinforcement technology, advanced processes, and thickening of the convex top ensure the high load and compressive performance of the product.
Space: The product thickness is only 8-20mm, which greatly saves building space compared to traditional pebbles and ceramic particles.
Root blocking: HDPE material has the characteristics of high strength and high density. After double track hot melt welding, the plant roots cannot penetrate the drainage board, effectively protecting the waterproof layer.
Anti corrosion: Acid, alkali, and salt in natural and general industrial environments cannot react with HDPE material products to achieve anti-corrosion effect.
Durability: Made of stable HDPE material, the product has long-lasting and stable performance, with a service life of over a hundred years
Diversity: The material itself is an excellent waterproof material, which can achieve functions such as waterproofing, drainage, breathability, isolation, moisture retention, thermal insulation, shock absorption, and partition after reasonable design
Cost: It has unparalleled cost advantages due to its small space occupation, fast and convenient construction, reliable performance, mature technology, and significant effectiveness.
Construction: The drainage board is lightweight, easy to handle and lay, and is specially equipped with overlapping buckle straps or welding straps. The overlapping only requires simple overlapping, and the construction quality on the installation site is clear at a glance. With a little professional training, the construction quality can be supervised. Four people per group, with a daily construction volume of 2000 square meters.
