Special Civil Services supports the field conditions that make infrastructure work successful. WCCL provides HDPE and fiberglass manhole welding, certified Predl repair services, GU-certified manhole modifications, saw cutting and new channel installation, channel modification, coring and channel rehabilitation, manhole vacuum testing, sewer-line testing, extrusion-welding testing, concrete coring under 24 inches, and concrete grouting—from a single manhole to dozens of manholes at a time. Our team also provides waterproofing and leak repair using injection and chemical grout; leak repair with hydrophobic grout or hydraulic cement; and installation of coalescent packs and filters in concrete structures. We coordinate access, sequencing, confined-space logistics, quality control, and clear communication around each project.
