Over burdened treatment plants, increased treatment costs,
surcharged lines and environmental pollution are the results of
infiltration. For years, efforts to reduce or correct infiltration and its
associated problems have concentrated on rehabilitating the
mainlines, although manholes and other underground structures
commonly account for 30 to 50 percent of a system's infiltration.

•        Leaking manhole rings
•        Cycle loading from groundwater
•        Infiltration through loose mortar
•        Leaks around stub outs
•        Subsidence from traffic loading
•        Infiltration through precast joints
•        Cracks caused by shifting & expanding soil
•        Drainage from Micro-Biological corrosion
•        Hydrogen Sulfide formation

Our manhole rehabilitation specialists can solve your manhole
infiltration/inflow problems; restoring your structures to "better than new"
condition in less time than it would take to replace them — and for a
fraction of the cost.

Epoxy: Our technicians use a wide range of 100% solids, zero-VOC
epoxies to meet your exact requirements. These ultra high-build
products can be sprayed or troweled on. They are modifiable to meet
specific flexural modulus and strength, cure fast even under water, and
provide premium corrosion resistance where high concentrations of
hydrogen sulfide, sulfuric acid, sodium hydroxide, hydrocarbons and an
array of other chemicals are present.

Cementitious: We also perform cementitious manhole rehabilitation using
products that are blended specifically for the job at hand. These unique,
high-strength helps restore structural integrity to deteriorating manholes
and provide a permanent seal against corrosion, infiltration and

Manhole Chimney Sealing: A major source of infiltration/inflow in
manholes is the connection between the frame and the chimney.
Freeze/thaw cycles and heavy traffic constantly stresses the connection,
eventually creating an opening where surface water readily enters the
