Polymer Waterproof Mortar | High Performance Cementitious Waterproofing Coating for Concrete & Masonry Surfaces

 G1 adopts inorganic-polymer composite formula to form dense hydration layers that fully block capillary water channels, reaching 1.5MPa 7-day anti-seepage pressure to bear long-term static water pressure. It delivers ≥1.2MPa tensile bonding strength for reliable backside waterproofing on concrete and brick substrates, with built-in polymer fiber to buffer slight base shrinkage and avoid waterproof layer cracking. The inorganic base material resists UV, corrosion and aging, with a service life consistent with buildings and stable performance through high temperature and 50 rounds of freeze-thaw cycles.

G1 is non-toxic, odor-free and fully compliant for drinking water tanks, safe for indoor and enclosed wet spaces including bathrooms, kitchens, swimming pools and underground tunnels. It integrates waterproof sealing and substrate leveling into one single material, simplifying construction workflows and lowering total labor & material costs. Easy mixing at a 4:1 powder-to-water ratio, it can be troweled or brushed directly, with layered application allowed for thickness over 10mm to eliminate hollowing defects.

G1 fits nearly all common wet construction projects such as basements, tunnels, pools and exterior walls, with simple base preparation and low construction requirements. It can withstand long-term soaking, alkali erosion and temperature fluctuations without peeling or cracking, reducing later maintenance costs drastically. Storable for 6–12 months in dry cool environments, it brings consistent batch quality for residential renovation and large industrial waterproof projects, a reliable one-stop solution for permanent building moisture protection.
