Concrete Sealer

Concrete Sealers

The strength and durability of concrete makes it an important structural material. However, concrete’s porous nature allows it to absorb water and soluble salts, which can be destructive. Further, when steel reinforcement is embedded in concrete to increase its strength, concrete’s absorption of salts, particularly chlorides, will eventually cause corrosion issues. Therefore, protection of concrete …
