Since 1999, Midlands Contracting has been using trenchless technology to install and rehabilitate underground utilities. Since our first pipe bursting project in Sargent, Nebraska, we have filled our trenchless toolbox with all the latest rehab methods, including on-grade directional drilling and cured in place sewer liners. When a sewer or water main needs to be replaced or rehabilitated we can get the job done without digging up the neighborhood.

PIPE BURSTING PIPELINE REPLACEMENT:
Midlands Contracting has been performing pipe bursting since 1999. Pipe bursting is a "less trench" technology used to replace aging sewers and water mains with minimal excavation. If your sewer or water main is under paving or close to other utilities then pipe bursting can save you money. When compared to sewer liners, the advantages of pipe bursting are its ability to upsize the existing pipe diameter and the fact that you are completely replacing the sewer or water main with a new pipe. Pipe bursting is divided into two types; pneumatic and static.
Pneumatic Pipe Bursting:
Pneumatic bursting uses an air powered bursting tool that jackhammers its way through the existing pipe. The tool is attached to a winch that is located at the downstream manhole. The winch provides the force to keep the tool on line and moving forward. As the tool fractures the host pipe the fragments are forced into the surrounding soil while a new high density polyethylene (HDPE) pipe is pulled in at the same time. After the bursting is complete, small excavations are made at the service connections to connect them to the main.
Static Pipe Bursting:
Static bursting involves the same process without the air and percussion action. Instead, brute force is used to pull the bursting head through the host pipe. Static bursting is the only method available to burst ductile iron pipes since the bursting head can be fitted with rolling blades that cut the ductile iron before splitting it. We can also static burst water mains using pre-chlorinated HDPE pipe so water service to your customers is only shut down for a few hours.

Sewer lining is the most popular type of sewer repair system due to its low cost and trenchless installation. We can install a liner from manhole to manhole to restore its structural integrity and to limit root intrusion and groundwater infiltration.
The process involves the inversion of a felt and resin liner tube into a damaged sewer. Hot water or pressurized steam is introduced into the liner to form-fit and cure the resin. Service laterals are then restored internally with robotically controlled cutters and cameras.
