Product Introduction:
Flexible Concrete Blanket, also known as concrete canvas, is a new type of flexible geosynthetic material composed of high-molecular fiber fabric, special fast-hardening cement, and aggregates. The finished product is in roll form, soft in texture, and can be bent, cut, and laid at will. After laying, it only requires sufficient watering for curing; no on-site concrete mixing, formwork erection, or professional mixing equipment is needed. It quickly hydrates and solidifies, forming a high-strength, high-density integral concrete protective layer after curing. It possesses excellent properties such as seepage prevention, erosion resistance, acid and alkali corrosion resistance, aging resistance, tensile and compressive strength, and strong integrity without cracking. Construction is time-saving, labor-saving, cost-effective, and environmentally friendly. It requires no large machinery and is suitable for various complex terrains. It is widely used in various water conservancy, municipal, landscaping, and geotechnical protection projects, including river and ditch slope lining, farmland irrigation canals, fishpond and reservoir seepage prevention and slope protection, roadbed slope reinforcement, mine ecological restoration, landfill closure, emergency slope protection, and temporary road surface hardening.

Product Applications:
Cement blankets are widely used in water conservancy and river management. Whether in rural streams, farmland irrigation ditches, urban waterways, or mountain torrent gullies, they can solve common problems such as riverbed erosion, canal leakage, and weak riverbanks. Construction is simple, requiring no complicated steps, and is more convenient than traditional river repair methods.
The most common application is for riverbank slope protection. Soil riverbanks are prone to collapse and soil erosion due to rainwater and floods. Cement blankets can be laid on uneven and winding slopes, quickly hardening into a protective shell after watering. This effectively resists the impact of water flow and waves, making it particularly suitable for river sections with many bends and loose soil, protecting riverbanks and surrounding farmland and houses.
Secondly, they are used for hardening and seepage prevention in irrigation canals. Traditional earthen canals are prone to leakage, collapse, and siltation. Cement blankets are laid on the bottom and sides of the canals, forming a smooth, hard shell after hardening. This prevents water leakage, improves water conveyance efficiency, and reduces siltation. Frequent cleaning and repairs are unnecessary, and construction is quick and does not disrupt irrigation or drainage.
It can also be used for riverbank reinforcement, laid on both the upstream and downstream sides of the embankment, acting like a "protective coat" to block rainwater seepage and erosion of the embankment base, thus improving flood control capabilities. It can be quickly laid and reinforced before the flood season, protecting surrounding villages and farmland.
Furthermore, in remote and complex scenarios such as mountain torrent gullies and the entrances and exits of water diversion tunnels, cement blankets are easy to transport, require no large machinery, and after hardening, are erosion-resistant, wear-resistant, and frost-resistant, enabling rapid protection. They are suitable for harsh outdoor environments and ideal for small river channel management and flash flood prevention.
In small river channel restoration, cement blankets can repair damaged slopes and solidify slope surfaces. If gaps are left for planting aquatic plants, both protection and ecological benefits can be achieved.
Cement blankets, with their advantages of flexibility, rapid hardening upon contact with water, high strength, impermeability, erosion resistance, corrosion resistance, and aging resistance, have a wide range of applications. They are widely used in water conservancy and river engineering for riverbank protection, ditch lining, drainage ditch reinforcement, and ecological slope protection of river channels, effectively preventing rainwater erosion and soil loss. In agriculture and aquaculture, they can be used for seepage prevention and slope protection of fish ponds, shrimp ponds, reservoirs, and farmland irrigation ditches, offering good seepage prevention and simple maintenance. They are also extensively used in municipal and landscaping projects, including drainage ditches in urban residential areas, pipeline trench protection, and parks. It can be used for landscape slope protection, artificial lake and landscape stream seepage prevention and landscaping; in highway and railway infrastructure, it is suitable for roadbed slope protection, roadside drainage ditches, culvert entrance and exit reinforcement and simple mountain slope support; it can also serve mine environmental protection and management, as a seepage prevention slope and dust solidification cover for mine revegetation slopes, tailings ponds and slag heaps; in addition, in flood control and emergency rescue, it can quickly complete the reinforcement of collapsed slopes, river embankment flood control slope protection, temporary water blocking and seepage prevention of breaches, and can also be used for hardening of sewage ditches in farms, temporary ground of factories, desert windbreak and sand fixation and other types of rock and soil protection and simple hardening projects.
