McCorkendale Construction specializes in underground boring and tunneling for sanitary sewers, water mains, and storm sewers.  We can dig pits, provide shoring, and install carrier pipe with this service.  12” to 48” steel casing is available for these operations.  Larger size tunnels are also available, using hand-mining-tunnel liner methods.  These methods are usually applied to cross roads, highways, multiple cross-country pipelines.
