What Is a Seal?
A seal is a building material commonly used in civil engineering and construction to instantly solidify and stop water leaks from cracks and joints in concrete structures.
Seals come in various types, including cement, asphalt, and synthetic resins like polyurethane and polyolefin. All these materials are designed to cure quickly, enabling rapid response to water leak issues.
There are also environmentally friendly water-based seals that do not contain organic solvents, and alkaline seals that help prevent corrosion in reinforcing steel and steel frames.
Uses of Seals
Seals are extensively used in various concrete structures, such as basements, water and sewage systems, reservoirs, swimming pools, water pipes in hydroelectric dams, tunnels, and underground passageways. They effectively stop water leakage in critical areas.
Additionally, seals are employed to prevent water leakage around electrical conduits, pipe and duct gaps, manholes, underground pits, sleeves, and bellmouths, and to prevent condensation inside electrical boxes.
Water sealing agents are also utilized in maritime construction, such as sealing water springs in breakwater seawalls. Moreover, they are widely used for concrete repair, anchoring bolts and reinforcing bars, and temporarily fixing stones, tiles, and blocks.
