Sewer Rehabilitation
Chemical grouts do not stop leaks simply by filling
joints and cracks. Instead, grout is forced through joints and cracks and
into the surrounding soil where it solidifies with the soil to form a
waterproof mass which cannot be pushed back into the sewer system. |

Sealing Manholes with
Chemical Grout
Chemical grout can permanently stop
water infiltration and seepage into all types of manholes. Gel type
chemical grout is injected from the inside of the manhole to the outside
to form a gel curtain around the outside of the manhole. The gel curtain
prevents ground water from flowing into the manhole and also
stabilizes the soil. The stabilization of the soil helps to prevent ground
water from washing away the supporting soil. In pre-cast manholes,
urethane foam grouts are sometimes used to rebuild the gaskets in the
joints. |

Seal Leaking Joints with Chemical
Grout
Chemical grouts do not stop sewer
leaks simply by filling joints and cracks. Instead, grout is forced
through joints and cracks and into the surrounding soil where it
solidifies with the soil to form a waterproof mass which cannot be pushed
back into the sewer system.
This water-tight collar adheres to the outer surface of the pipe or
manhole where it will stay indefinitely unless removed by excavation or
exposed to sunlight for long periods of time. If groundwater pressures
increase, the collar will be pressed more tightly against the structure,
increasing its ability to stop leaks. |

Sealing Service Laterals with
Chemical Grout
Service laterals are often a source
of significant infiltration, but without chemical grout it is seldom
cost-effective to stop leaks. It usually costs less to treat the
groundwater than to dig up and repair or put a liner in these lines.
However, chemical grout is so economical and effective that a positive
return on investment can be realized immediately.
Studies have shown that most infiltration into service lines occurs within
a few feet of the main. The two primary reasons for this are that all
except the last few feet of service lines are usually above the water
table, and groundwater flows easily in the backfill of a mainline trench
because of the French drain effect. This means that a poorly constructed
lateral connection or mainline lateral connection can be a significant
source of inflow and infiltration that is easily addressed with chemical
grout.
Most mainline rehabilitation procedures do not solve the problem of
leakage into the main caused by a leaky connection at the service line.
Grouting the mainline or grouting service lines after lining will stop
these leaks and also stop water migrating through the annular space around
the liner. |

Concrete Rehabilitation
The use of chemical grout in crack
injection is a proven method of stopping leaks in dams, tunnels, parking
garages, tanks, vaults, mines or any structure where water is migrating
through the concrete. Crack injection with chemical grout can not only
stop the water, it can stop or slow the deterioration of rebar or other
internal features of the concrete. This success is due to the placement of
chemical grout throughout the depth of the crack, compared to only surface
sealing with epoxy. |

Stop Leaks in Mines
Water flow and associated
maintenance and power costs do not have to be an ongoing problem. Chemical
grout can permanently stop water flow, saving time and money. For 20
years, Avanti has been a leading supplier of chemical grouts that stop
leaks as small as drips and as large as gushers. |

Stabilize Soils
The use of chemical grouts
for soil stabilization includes, but is not limited to, preventing
contaminated plume migration, controlling water flow, and increasing
compressive strength. Generally, chemical grouts are used where longevity
and a high degree of impermeability are required. Chemical grout can also
be used with Ultrafine cementitious grouts to achieve extremely low
permeabilities at optimal costs |
