The above specifications are common specifications, can be customized into grout stop strips. If the above specifications do not meet your needs, you can select others and then explain in the remarks.
Length and width are divided into 2000mm×1000mm
According to user needs, boards and strips of different thicknesses from 5-50mm can be arbitrarily processed and produced, with slicing errors within ±0.2 to ±1.
Closed-cell foam board has an independent closed-cell bubble structure, with honeycomb-like holes evenly distributed in appearance. It is firmly and tightly integrated with cement adhesives. It naturally adapts to expansion and contraction changes, enhancing the expansion water-stop effect.
The high density of closed-cell foam board has replaced traditional materials such as three-oil four-felt, asphalt and wood fir boards. Moreover, polyethylene foam board is environmentally friendly (using it responds to the slogan of everyone's environmental protection, green environmental protection), simple to construct, and its anti-seepage and anti-leakage effects cannot be underestimated. L-600 type density reaches 104Kg/cubic meter; L-1000 type density can reach 90104Kg/cubic meter. The density of closed-cell foam board also determines the level of its waterproof performance on the one hand. Because the foam board has low density, its waterproof and anti-seepage properties are greatly enhanced. The water absorption rate of foam board is extremely low, calculated in cm3.
In addition to its strong waterproof performance, closed-cell foam board also has other characteristics such as: cold resistance (no brittle cracking at low temperature), high temperature resistance (no flowing at high temperature), corrosion resistance (not afraid of hydrochloric acid, alkali substances), independent bubble structure, high recovery rate and aging resistance. Its various characteristics have promoted the increasingly wide application range of joint filling boards. Closed-cell foam board has been applied to joint boards for concrete highway expansion joints; bridge joint water-stop boards; expansion joint boards for water conservancy project dams, dam protection, stilling basins, slope protection, and retaining walls; water-stop joint boards at the bottom of hydropower, thermal power, engineering, and water towers; settlement joints for construction, joint filling boards for frame structures; water-stop joint filling boards for drinking water plants and sewage treatment plant pools; joint boards for airport runways; joint boards for ports, docks, and concrete; water-passing joint boards for water tunnels and tunnel concrete; water-stop joint boards for subway and underground passage concrete.
