 Our
line of Prime Flex polyurethane resin products are used to
stop leaks and to fill underground voids without digging.
These low viscosity injection resins are long-lasting solutions
to leaks in manholes, utility vaults, meter boxes, tunnels,
tanks, clarifiers, aeration basins, lift stations, pump stations,
catch basins, elevator pits, below-grade walls, equipment
pits, lateral connections, mainlines, dams, channels, flumes,
swimming pools, concrete basements, and many other areas requiring
waterproofing. Some chemical grouts cure to a rigid or flexible
foam, while others to a flexible gel.
We offer two major types of leak repair resins: hydrophilic
and hydrophobic. Hydrophilic grouts readily mix with
water and seek out water to get an excellent "bite"
into the pores of wet concrete. This is important when trying
to seal a crack in wet concrete. Hydrophilic grouts are used
to stop leaks through cracks and joints in underground structures.
When cracks or joints open and close with temperature changes,
a tight water seal and bond is maintained due to the flexibility
of a hydrophilic grout. Hydrophobic grouts are typically used
to fill voids and stabilize soils due to their low viscocity,
high expansion rate, and ability to set up under wet conditions
without diluting. A hydrophobic resin repels water. When injected
into loose soil or voids, it expands and replaces any water
present. Because rigid hydrophobic material is not affected
by fluctuation in the moisture content of soil, it is virtually
unaffected by water table. It retains its strength, size,
and impermeability under almost all soil conditions. |
