CONCRETE PAVEMENTS APPLICATION FIELD SOLUTION

As we all know, most airport runways, highways, tunnels and bridges are paved with high-strength cement concrete. Concrete is a rigid material in nature

with low flexural strength made up of inorganic binder cement, sand, gravel and water. Usually, there are joints in concrete structures and joints should be

sealed in order to prevent passage of gases, liquids, solids or other undesired substances into the gaps or through them. Based on the long-term

practical experience, we can know that polyurethane sealants are the most proper sealant, and the reasons are as follows.

CONCRETE PAVEMENTS

——

First of all, polyurethane sealants can create strong bonds of concrete and seal joints to prevent fluids, wind, gases and other substances from passing through. Besides, concrete always changes its plane due to atmospheric conditions. Carbonation may take place and the overall effect may be contraction because of its drying and shrinkage. Expansion and contraction may occur due to change in cyclic effects or change in environmental conditions like humidity and temperature or the extra load on to cracking. Polyurethane sealants have high elasticity with a tough, durable, flexible consistency, which can adapt to the changes of concrete due to atmospheric conditions. Finally, polyurethane sealants are self-leveling, waterproof, weatherproof, available in colors and have good resistance to chemical corrosion. These properties can protect concrete pavements well and prolong their service life.

SELF LEVELING SEALANT

——

Self-leveling sealant plays a vital role in road and pavement construction. Roads, bridges, and airport runways are constantly exposed to heavy traffic, weathering, and structural movement, making joint sealing an essential step to ensure safety and durability. Without proper sealing, cracks and joints can allow water infiltration, accelerate surface damage, and compromise the overall performance of concrete structures.

Our self-leveling sealant provides a reliable solution with excellent adhesion to concrete, fast curing, and long-lasting flexibility. It ensures smooth joint filling, prevents pollution, and can even be painted for a clean finish. By sealing construction joints, road cracks, and runway surfaces, it effectively extends the service life of infrastructures and maintains structural integrity under demanding conditions.
