JL-322 water swelling water-proofing gel(the JL-322) is a type of water-swelling, single-fluid and elastic sealant.

With prepolymer of polyurethane as the base, it contains urethane produced by special technology.

It has dual-sealing water –stop of concrete construction joints and antiseep of various pre-embedded components.

JL-322 may solidify at humid environment. The curing time depends on environment temperature and humidity.

The higher of the temperature and humidity , the shorter of the curing time.

Carry out next concrete grouting after the surface hardened (tacky dry).

Buffer plumping property of JL-322 water-swelling water-proofing gel

JL-322 has buffer plumping property, its 7d expansion rate account for 39.3% of the final expansion. Before the next concrete grouting , it is rarely occurs expansion caused by various construction environment.
