Waterproof board is also called geomembrane. It is customary to call thick geomembrane waterproof board, and thicker geomembrane is called geomembrane. It is based on high molecular polymer. A kind of anti-seepage material made of, divided into homogeneous waterproof board and composite waterproof board.
Use of waterproof board
The waterproof board has a wide width, a weight of /square meter, and high physical and mechanical properties such as tensile strength, tear resistance, and burst resistance. The product has high strength, good elongation performance, and deformation modulus. It has the characteristics of large quantity, acid and alkali resistance, corrosion resistance, aging resistance, and good anti-seepage performance. It can meet the needs of civil engineering such as anti-seepage, isolation, reinforcement, and anti-crack reinforcement in water conservancy, municipal administration, construction, transportation, subways, tunnels, and engineering construction. Because it uses polymer materials and adds anti-aging agents in the production process, it can be used in unconventional temperature environments. This kind of waterproof board is often used for anti-seepage treatment of dams and drainage ditches, as well as anti-fouling treatment of scrapyards.
Characteristics of waterproof board
Strength: Under the same weight specifications, the tensile strength in all directions is higher than other needle-punched non-woven fabrics.
Anti-UV light has extremely high UV resistance.
Extreme high temperature resistance: It can withstand high temperatures up to ℃, and still maintains structural integrity and original physical properties under high temperatures.
Permeable and flat drainage waterproofing boards are thicker and needle-punched, with good flat drainage and vertical water permeability, and can still maintain this performance after many years.
The creep resistance of the creep-resistant waterproof board is better than that of other geotextiles, so it has good long-term performance. It can withstand the corrosion of common chemicals in the soil and the corrosion of gasoline, diesel, etc.
The ductile waterproof board has a good elongation rate under a certain stress, allowing it to adapt to uneven and irregular base surfaces.
Characteristics of waterproof board
, excellent flexibility, impermeability, elongation and wear resistance
, good isolation and puncture resistance
, no chemical pollution
, resistant to acid, alkali and various chemical substances, good dimensional stability, good adhesion, and easy construction.
Waterproof board
Laying method
Lay in a certain direction, and do not pull it too tightly. There should be a certain amount of expansion and contraction to adapt to the deformation of the matrix.
When laying the water board, the direction of each unit must be adjusted to facilitate the welding of the two units
After the water board is laid, it must be pressed with sand bags to prevent wind and sand from affecting the welding of the next edge.
Waterproof board welding
Seam treatment is a key procedure in construction. Thermal welding method is generally used. The surfaces where the membranes are connected are heated to melt the surface, and then fused into one through pressure.
For the laid waterproof boards, the edge joints are required to be free of oil, moisture, dust, etc.
Before joining, adjust the two sides of the single film at the seam so that they overlap to a certain width. The overlap width is generally ~cm and is flat and wrinkle-free.
Use a special welding machine for welding.
