Services
Manhole Rehabilitation
We specialize in spray-applied epoxy and cementitious rehabilitation for structurally compromised manholes. Our solutions stop infiltration, inflow, and hydrogen-sulfide corrosion while restoring integrity. Services include chimney sealing, lateral lining, and vacuum testing for municipal and industrial clients.
Casting Adjustments
Precision raising or lowering of manhole castings, valve boxes, and curb inlets to match road grades. Using brick, mortar, and concrete, we ensure seamless integration with paving projects while maintaining watertight seals and OSHA compliance.
Tunnel Rehabilitation
Structural reinforcement and leak prevention for large-diameter tunnels using epoxy, cementitious coatings, and chemical grouting. Our methods eliminate infiltration, prevent cave-ins, and extend service life for stormwater and wastewater systems.
Chemical Grouting
Hydrophilic and hydrophobic grout injection to seal cracks and voids in manholes, tunnels, and pipelines. This technique stops water intrusion, stabilizes surrounding soil, and prevents further structural degradation in critical infrastructure.
Lateral Lining
Cured-in-place lateral lining using LMK systems to repair sewer laterals without excavation. This trenchless solution restores pipe integrity, prevents root intrusion, and extends service life while minimizing surface disruption.
