Plastic Drainage Board /Dimple Drainage Board

Technical standard: JC/T2112-2012

Product Introduction

A layer of filtering geotextile is glued to the top surface of the conical protrusion to prevent soil particles from passing through, thus avoiding blockage of the drainage channel and allowing the pore to drain smoothly. The traditional drainage method uses masonry tiles as the filter guide layer and more cobblestones or gravel as the filter layer to drain the water to the designated location. In contrast, the use of drainage boards instead of cobblestone filter layer saves time, energy and investment, and reduces the load on the building.

A good drainage system plays an important role in the construction cycle of civil engineering and the normal use and life of the structure. The drainage board and the porous percolation pipe form an effective drainage system, and the cylindrical porous drainage board and the geotextile also form a drainage system, thus forming a system with water percolation, water storage and drainage functions.

Product Categories

Plastic drainage board is divided into two series: rolls and sheets. The shape is made by a special process of pressing plastic sheets to form a closed and raised columnar shell, forming a concave and convex membrane with a continuous shell, three-dimensional space and a certain support height, with butyl rubber strips hot glued to the edges during processing and production, and the top of the shell is covered with a geotextile filter layer for water infiltration, hydrophobic, drainage and water storage. Also known as: lap bonded drainage board, drainage sheet, drainage protection board, water filter board, plastic concave and convex drainage board, plastic sandwich board. The product specifications are divided into square greening and basement, and there are H20 and H25 specifications for selection.

The drainage boards commonly used in construction are: plastic drainage board, storage drainage board, coil drainage board, impermeable drainage board, composite drainage board, three-dimensional drainage board, sheet drainage board, etc.

Main Functions

- Water conductivity and drainage

The concave-convex hollow standing rib structure that all the anti-drainage protection boards have can quickly and effectively export rainwater, greatly reducing or even eliminating the hydrostatic pressure of the waterproof layer, and through this active water conduction principle can achieve the effect of active waterproofing.

Waterproof performance: polyethylene (HDPE) polystyrene (PVC) drainage protection board material itself is a very good waterproof material. By using a reliable connection method, the drainage protection board becomes a good auxiliary waterproofing material.

- Protective shielding properties

Anti-drainage protection board can effectively protect the structure and waterproof layer, and resist all kinds of acids and bases in the soil and root thorns of plants. It can protect the building and waterproof layer from damage when backfilling the outer wall of the basement.

- Sound insulation and ventilation and moisture-proof function

Laboratory data shows that polyethylene (HDPE) polyvinyl chloride (PVC) anti-drainage protection board can effectively reduce indoor noise by 14 decibels at 500HZ, which has obvious noise reduction and sound insulation function. Waterproof water guide plate can also play a good role in ventilation and moisture control when used on the ground or wall.

Applications

Greening project: garage roof greening, roof garden, vertical greening, pitched roof greening, soccer field, golf course.

Municipal engineering: airports, road foundations, subways, tunnels, landfills.

Construction engineering: upper or lower layer of building foundation, inner and outer basement wall and bottom slab as well as top slab, roof impermeability and heat insulation layer, etc.

Water conservancy engineering: waterproof reservoirs, reservoirs, artificial lakes and waterproof seepage.

Traffic engineering: highway, railroad roadbed, embankment and slope protection layer

Construction specifications

1、Please store the drainage board in a dry and ventilated environment to prevent exposure to the sun and keep away from fire sources.

2、Please put the drainage protection board upright or flat, do not tilt or cross the horizontal pressure, do not stack the height of more than 3 layers, do not stack heavy objects.

3、Paving should be flat and natural, laid down the slope or according to the direction of water flow.

4, single laying geotextile lap to ensure that 150cm, lap with rubber or sand compaction to avoid movement, and then backfill, the first layer of backfill soil to ensure tamping before the next step, layered backfill must be tamped
