Tongfu is a specialized Chinese manufacturer and supplier of weed barrier fabrics, geomembrane liners, and concrete blanket mats. Unlike traditional slope protection and waterproofing methods—such as on-site concrete mixing, brick masonry, or the installation of rigid precast panels—our concrete blanket mat undergoes rapid hydration upon contact with water. It eliminates the need for on-site aggregate mixing or heavy mixing machinery; once hydrated and cured, it forms a high-strength, impact-resistant, impermeable, and crack-resistant concrete protective layer.
What is a Concrete Blanket Mat?
Also known as a concrete blanket or flexible cement protective blanket, this product is a novel composite material designed for waterproofing and protection in construction. It is manufactured by integrating high-density fiber fabric, specialized dry cement powder, and a polymer waterproofing layer into a single unit, representing a new class of inorganic, hardening construction material. It combines the installation flexibility of fabric with the robust protective qualities of concrete, allowing it to be easily bent and fitted to irregular slopes and trench contours with zero construction waste. Widely used in applications such as hydraulic slope protection, canal waterproofing, roadbed protection, slope reinforcement, fish pond lining, and temporary site surfacing, it has become a highly popular material for lightweight construction in infrastructure, water conservancy, and municipal projects.
How do you choose a high-quality cement blanket?
The quality of cement blankets on the market varies significantly. Inferior, low-cost products often suffer from critical flaws, such as insufficient cement content, weak fiber tensile strength, cracking and crumbling after curing, poor waterproofing performance, and failure to cure properly in low temperatures. Many such products fail shortly after installation, necessitating costly rework. To select a reliable, compliant concrete protective blanket, look for these four key criteria: First, examine the base fiber—it must be made of high-tenacity polyester filament to ensure it does not tear during installation. Second, check the cement content—there must be an adequate amount of high-grade dry cement powder to guarantee the required hardness after curing. Third, verify the waterproofing layer—it should feature an integrated, continuous polymer membrane to prevent water seepage. Fourth, consider curing adaptability—the material should perform well in diverse outdoor temperatures, cure rapidly upon hydration, and remain unaffected by minor weather-related temperature fluctuations.
Core Product Advantages
Our factory specializes in three main product lines: standard GB-compliant cement blankets, thickened high-strength cement blankets, and composite impermeable cement blankets. The entire product range has been certified by the National Geotechnical Construction Materials Testing Center; key metrics—including tensile strength, elongation at break, impermeability coefficient, and compressive strength—all meet construction standards for municipal and hydraulic engineering projects.
1
Rapid hardening upon contact with water; simple, low-barrier installation
No concrete mixers or manual aggregate proportioning are required. On-site installation involves simply unrolling the material and spraying it evenly with water. It sets initially within 12 hours and fully cures within 24 hours. Compared to traditional concrete construction, the project timeline is reduced by over 70%. Small-scale installations can be completed by a single person, significantly saving on labor and machinery costs.
2
Flexible contouring; adaptable to complex slopes and channels
Before curing, the cement blanket is as flexible as fabric; it can be bent and cut at will to perfectly fit irregular surfaces such as curves, steep slopes, uniquely shaped channels, and uneven subgrades. It avoids the poor fit, hollow spots, and cracking issues common with traditional concrete, offering far superior terrain adaptability compared to rigid concrete slabs.
3
High impact strength; resistant to compression, cracking, and abrasion
Once cured, the material achieves excellent compressive strength and outstanding resistance to bending, impact, and crushing loads. It withstands long-term rainfall erosion, river current impact, and occasional vehicle traffic. It does not crack, crumble, or spall during long-term outdoor use, offering a service life of over 10 years.
4
Integrated impermeable structure; eliminates leakage risks
Featuring an internal high-density impermeable composite layer, the product is formed as a seamless, integrated unit. With no joints or seams, it completely blocks water infiltration, preventing water loss from channels or fishponds while also protecting the underlying soil from groundwater erosion—serving the dual functions of slope protection and impermeability.
5
Weather-resistant and anti-aging for all-weather outdoor use
Formulated with specialized additives for anti-aging, freeze resistance, and acid/alkali resistance, the product withstands northern freeze-thaw cycles, southern high-temperature exposure, and corrosive river water. It is cold- and heat-resistant, corrosion-proof, and adaptable to diverse climatic environments across the country, requiring no additional anti-corrosion treatment.
6
Eco-friendly and pollution-free; no construction waste
Pre-filled with dry cement powder at the factory, the product generates no dust or excess construction waste during on-site installation. It releases no harmful substances after curing, ensuring no pollution to river water or surrounding soil, and complies with environmental standards for hydraulic engineering.
7
Easy to cut and customizable
Can be cut on-site using a standard utility knife to fit various ditch widths and slope dimensions. Factory customization is also available for specific thicknesses, widths, and lengths to meet diverse project requirements, ranging from small ditches to large-scale hydraulic slope protection and roadbed reinforcement.
8
Maintenance-free; reduced operational costs
The cured structure is stable, requiring no periodic repairs or anti-corrosion maintenance. A single installation ensures long-term use, effectively eliminating common issues associated with traditional slope protection—such as weed overgrowth, wall cracking, and water seepage—thereby significantly lowering long-term maintenance expenses.
Advantages of Direct Supply from the Manufacturer
As a manufacturer with over a decade of experience in the geotechnical engineering materials sector, we operate a fully integrated, automated production line for cement blankets. We handle the entire production process in-house—from fiber weaving and cement filling to composite lamination, slitting, and packaging—without any outsourcing. Compared to market intermediaries and traders, we offer the following advantages:
1. Strict raw material control; no inferior fillers
Low-priced cement blankets on the market often use low-grade cement and short, inferior fibers, resulting in insufficient hardness and a tendency to crumble or crack after curing. Our impermeable cement blankets utilize high-grade rapid-hardening cement and high-strength polyester filament fibers. Every batch of raw materials undergoes random testing for compressive and tensile strength, ensuring the hardness and toughness of the finished product at the source and preventing substandard materials from reaching the construction site.
2. Ample stock and rapid shipping for custom orders
Multiple fully automated production lines operate simultaneously at the factory. We maintain massive inventories of standard 4mm, 6mm, and 8mm thick cement blankets (compliant with national standards) and ship orders on the same day they are placed, ensuring no delays to construction schedules. We also support project-specific customization—producing blankets with special widths, increased thickness, or reinforcement ribs based on construction blueprints—and can rapidly fulfill orders of any size.
3. Triple quality inspection; zero-defect products for projects
We implement three independent quality control stages: first, testing fiber tensile strength to prevent breakage during installation; second, checking the uniformity of cement filling to avoid localized material shortages that could prevent proper curing; and third, conducting simulated outdoor aquatic environment tests for curing and impermeability. All outgoing products come with official inspection reports and certificates of conformity, fully meeting site inspection and acceptance requirements.
4. Factory-direct supply with no middlemen; lower project quotes
By eliminating markups from agents and wholesalers, we deal directly with project owners, construction teams, and distributors, offering factory-direct pricing. For products of equivalent national-standard quality, our quotes are 18%–25% lower than those of market intermediaries. Large-scale project orders qualify for special tiered pricing, effectively controlling overall project costs.
