A polymer-based elastic waterproofing material. Two components, cold spray-applied, wrapping the substrate completely to form a seamless, "skin-like" waterproof membrane. Trusted in high-speed rail, metro, nuclear power, new energy, aviation, environmental, and large public building projects.
The material contains no organic solvents, and its life‑cycle carbon emissions can be reduced by up to 86%.
The adhesion strength between the coating and the concrete substrate is ≥0.4 MPa at 7 days and ultimately reaches 0.7 Mpa (matching the material's own strength). This ultimately forms a continuous, dense, and seamless "skin‑type" protective layer, effectively eliminate the water channeling problem caused by lap joints or poor adhesion commonly found in traditional materials.
The elongation at break averages 1000%–1700%, with a recovery rate of over 85%. It has passed 2 million cycles of fatigue simulation tests for railway applications, offering resistance to tearing and puncturing, and exhibits self‑healing properties.
Tested in accordance with GB/T 1771‑2007, the material exhibits no blistering, rusting, cracking, or peeling after 1,500 hours under neutral salt spray conditions. With a water permeability of 0 mm, it is suitable for anti‑seepage and anti‑corrosion applications in hydraulic engineering, dam structures, and wastewater treatment.
According to GB/T 23457-2017, the peel strength with post‑cast concrete is required to be ≥1.5 N/mm. The actual tested value reaches 4.1 N/mm three times the requirement. When applied to basement floor slabs, sidewalls of underground structures without slope, or mined tunnels, it ensures full adhesion between the waterproofing layer and the water‑facing side of the structure, thereby guaranteeing effective waterproofing.
According to GB/T 16777-2008, the coating has a low-temperature flexibility of −50 °C and a high-temperature resistance of 160 °C, and is applicable to a wide range of temperature conditions.
The coating exhibits outstanding aging resistance. According to GB/T 18244‑2022, the accelerated weathering test result shows as high as 10,000 hours, which corresponds theoretically to a service life of more than 80 years.
Mechanical spraying is carried out at room temperature, producing no toxic or harmful gases and posing no fire safety hazards. The coating sets within 4 seconds of spraying, and the design thickness can be achieved in a single pass. Construction efficiency is 4-10 times that of traditional processes.
The material releases its own water as it cures. Construction can be carried out as long as the moisture content of the substrate is below 28% (damp, with no standing water). No downtime during the rainy season. This solves the pain point that traditional waterproofing materials cannot be applied on damp surfaces.
We have developed a patented winter‑construction product that overcomes the technical challenges of applying water‑based coatings in cold weather, enabling normal application at temperatures above -15°C.
Components A and B are sprayed through twin nozzles in fan patterns that intersect in the air. On contact with the substrate, an electrolyte reaction breaks the emulsion instantly, curing into a dense, continuous rubber membrane — true "skin-type" waterproofing.
