Foundation pit support, also known as temporary slope protection engineering, commonly uses concrete as the material. However, concrete slope protection is costly, difficult to construct, takes a long time, and the later demolition work is also very troublesome. So is there a good material that can replace it?
The new type of slope protection material, cement blanket, is a composite material composed of cement, sand, non-woven fabric, and woven fabric. It uses a needle-punching process to combine concrete with the blanket, effectively turning concrete into a blanket form. It comes in rolls which are convenient for transportation. Before use, it is as soft as a blanket, and construction only requires laying the blanket and sprinkling water, without the need for skilled construction personnel or heavy machinery like mixers. After watering and curing, it becomes as solid as concrete. At the same time, the internal structure of the cement blanket is a fiber frame, effectively providing compression resistance and crack prevention. Guaranteed for ten years or more.
Cement blankets are custom products, with widths ranging from 1-4 meters and lengths as desired (commonly 5/10/15 meters). Thickness specifications range from 5mm to 16mm, and prices vary depending on thickness. For pond slope protection, 8-12mm is commonly used; for foundation pit support, 5-7mm is commonly used. Other common uses of cement blankets include roof protection, mountain and mine slope protection, fishing park slopes, ditch and riverbank protection, and road paving (but not for cars).
