Underwater Glass Fiber Sleeve Reinforcement system is mainly used to repair and strengthen the structural foundation, wharf pile foundation and pier column (including concrete pile, steel column and wood pile) with various diseases such as corrosion, scouring, concrete falling off and reinforcement leakage, as well as the pre protection of new pier column.
GENERAL
Scope of application
◆ Repair and reinforce concrete piles, steel pipe piles, H-shaped steel piles and wood piles that are scoured and concrete falls off in splash and tidal areas;
◆ Repair and reinforce concrete foundation of public facilities and equipment, electric poles, etc.
FEATURE
Underwater epoxy sealant still has super strong bonding force, self leveling and self compacting under water.
Fiberglass sleeve of underwater construction process is made of high-strength fiber composite material with excellent durability.
The fiberglass sleeve is made of unique material, and its properties remain unchanged for a long time.
Epoxy grouting material adopts high molecular polymer, which effect of anti-effect; The fiberglass sleeve is inert to chemical reaction and can resist various chemical agents.
