JTB-6683 Concrete Waterproofing Admixture provides reliable protection for reinforced concrete structures, ensuring long-term durability and safe normal operation. It does not adversely affect the inherent efficacy or mechanical properties of the construction materials.
• Long-lasting water-repellent
• Non-toxic, odorless
• Non-flammable, water-miscible
• Reliable waterproofing, weather & durability resistant
• Waterproof & wear-resistant, long service life
• Passivating effect
• Reduces material water absorption
• Protection for new concrete structures & repair/strengthening of existing concrete.
• Applications include ports, sea-crossing bridges, river bridges, dams, elevated roads, highways, railway bridges, tunnels, airport pavements, fair-faced concrete, thermal/nuclear power plants, sewage treatment plants.
• Protection of concrete structures against seawater, salt spray, de-icing chemicals, and freeze-thaw damage.
• Surface preparation: Before construction, repair the defects of the concrete structure first. Clean the loose dust, grease and loose substances on the surface of the base to ensure that the base surface is clean, tidy, solid and flat. Keep the surface dry for more than 3 days.
• Construction: When spraying liquid, continuous spraying should be carried out to ensure that the surface to be coated is saturated and overflows.
• Horizontal surface construction: Spray or brush until the base material surface is moist or mirror-like. On the vertical surface, the spray should be applied from the bottom up, with a vertical flow length of 15-20cm, keeping the surface to be coated moist for several minutes. The liquid concrete waterproofing agent needs to be sprayed twice.
• Maintenance: After construction, ensure that it is not exposed to rain for at least 24 hours and dries naturally in the air.
Packaging specification: Plastic drum, 50 kg or 20 kg per drum.
Storage: Store in a cool place.
Shelf life: 12 months in the original sealed packaging.

Setting a 40-tonne compressor on its foundation looks simple until you measure the gap: typically 25 to 80 millimetres between the underside of the steel baseplate and the top of the concrete. That gap carries the entire operating load, plus vibration, thermal movement and occas...
READ MOREA base plate sits 25 mm above a concrete foundation, and every tonne that presses, vibrates, or torques the equipment above it will pass through that gap. Fill it with ordinary mortar and the mix dries, shrinks, and pulls away from the steel. Leave it as-cast concrete and the co...
READ MOREA concrete patch usually fails where the new material meets the old one. Unmodified cement-sand mortars shrink as they dry, bond weakly to the prepared substrate, and open a hairline gap that admits water and chlorides — the very corrosion cycle you were trying to stop. Polymer-...
