McLeRoy’s latest trenchless excavation capabilities are on the cutting edge of technology.

Every day, thousands of miles of roads are blocked by road work, millions of gallons of fuel are wasted, air is polluted, accidents occur, buildings are damaged and people suffer from loss time. This loss of time, fuel and damage can be drastically reduced through trenchless excavation.

Trenchless excavation is a new method used in the United States that allows new pipe to be installed without shutting down roads and sidewalks — ultimately creating very little effect on traffic flow and saving municipalities the cost of rebuilding infrastructure above the utility.

Pipe bursting is an environmentally friendly and cost-effective alternative.

Pipe Bursting offers an economical solution to repair damaged pipes. According to estimates, the pipe bursting method has become the most widely applied trenchless pipe replacement method with more than 31,000 miles rehabilitated worldwide. This technique allows the replacement of defective pipelines in the same path without any substantial influences on soil and groundwater.

When is replacement necessary?

In general, it has to be decided whether repair, renovation or pipe renewal (replacement) is required.

A pipe replacement is necessary:

  • When repair or renovation is technically or economically inappropriate;
  • When the hydraulic capacity needs to be improved by a greater pipe diameter;
  • When repair or renovation offers only a short term solution with a pipe replacement being inevitable;
  • When there is a request for a long-lasting pipe durability and/or a higher product life span; and
  • When the static loading capacity of the defective pipe would be otherwise negatively affected.

Trenchless Technology (Slip Lining)

Often, trenchless techniques are the only viable construction option. Trenchless techniques are also often the least costly option as well as the least disruptive.

Slip Lining involves the installation, replacement, or renewal of underground utilities with minimum excavation and surface disruption. These technologies are and have always been used successfully for underground storm pipes.

Slip Lining is an attractive option for crossing roadways, and other transportation corridors, and rivers and waterways — particularly for construction in urbanized area with heavy vehicular and pedestrian traffic as well as numerous existing underground utilities. Slip Lining also can be used to install, rehab or replace utilities located in environmentally sensitive locations where surface access may be restricted due to the existence of structures or vegetation.

Other benefits of Slip Lining an existing pipe is increased flow as well as a new more substantial structure. Once the new pipe is placed in the existing pipe we use a system to pressure grout all of the voids between the two pipes and voids in the ground to greatly increase the structure and life of the drainage system.

Always Keeping Safety in Mind

At McLeRoy, there is nothing of greater importance than safety and loss prevention. We believe accidents resulting in employee injury or illness and damage to property and equipment represent needless waste and loss. That’s why it is the policy of McLeRoy to conduct all operations safely to help prevent injuries and illness to employees and damage to property
