Product Details Introduction of block storage and drainage board The block drainage board is connected by welding or buckle connection during construction, which can make the drainage board a closed whole and has the best effect on preventing root thorns. In order to increase the compression resistance, it is generally used together with plastic grids and geotextiles to form a complete overhead layer, which is beneficial to promote drainage as a whole. One disadvantage is that because the bumps are supported upwards, it is inevitable that the covering soil or planting soil will be pressed into the parts without bump support, or the bumps will block the drainage after the bumps are damaged, which will cause poor water flow. However, as long as the drainage board is not damaged and the water is blocked on the plastic board, it will not cause damage to the waterproof layer, and the function of waterproof and drainage can still be guaranteed. Because it is made of sheet material, its construction speed is fast, it is convenient to lay, and the overall cost is low. It is the most used drainage board. Application of block storage and drainage board 134-6566-2851 Uses: Widely used in roof greening, underground garage roof greening, golf course, lawn course drainage, and a large amount of water can be stored in the pillar. Each piece can be buckled together, and a layer of geotextile is laid on the paved drainage board to form a combined drainage board.

Features of block storage and drainage board 134-6566-2851 A good drainage system plays an important role in the construction period of civil works and the normal use and life of structures. It prevents the high wind from disturbing the drainage board and affects the laying quality. The block drainage board can form a block with water seepage, water storage and drainage functions. system. The block drainage board and the flaky drainage board are overlapped with geotextile, and blind ditch block drainage boards and flaky drainage boards are left around to prevent underground water from coming. Raise the floor block drainage board and sheet drainage board above the foundation, that is, make a layer of drainage board block drainage board and sheet drainage board before making the floor.Building Materials factory website:http://www.geotechnicalmaterial.com/building-materials/
