Grouting Agent(HI-SERIES)
Hifoam
series based on MDI or TDI polyurethane is a highly
effective polyurethane grouting agent recommend for
use as repair, reinforcement and waterproofing agent
in concrete structure.
Upon
contact with water Hifoam reacts to a closed cell foam
while expanding its volume up to 10-30 times.
The
cured material is flexible or rigid foam and does not
shrink or swell. So Hifoam is extremely well suited
for the filling of large cavernous spaces and cracks
in stone or concrete structure as well as for cutting
off gushing water of high pressure and speed. Due to
low viscosity of the materials, Hifoam offers
superior penetration in hairline crack injection.
Hiagel series is an essentially nontoxic hydrophilic modified
poly acrylate product which cures to a gel.
Because
the cured gel has properties of excellent elasticity,
adhesive strength and durability, Hiagel series
get permanent effect as waterproofing agent in crack
and joint of tunnel, building basement etc. |
