Underground Construction

Underground drilling is one of the leading methods of installation of an underground pipe. From installing new water lines, sewer lines, and gas lines to installing a new TV, Internet, or fiber optic lines, our Houston underground construction company can complete a wide variety of projects. The process begins when a directional drilling machine pushes a drilling head connected to a hollow pipe into the ground at an angle. As each joint of drill pipe is pushed into the ground a new one is added behind.

Pipe Bursting

Pipe Bursting is a trenchless rehabilitation method of installing High-Density Polyethylene (HDPE), PVC, or Ductile Iron pipe into damaged or deteriorated water and sewer lines. During the process, a bursting tool is guided into an existing pipe with a constant tension winch. The tool is equipped with an expander. As it travels through the host pipe, continuous percussion breaks the host pipe apart. The expander forces the fragments into the surrounding soil, while the new pipe is simultaneously pulled in place behind it.

CCTV (Pre and Post) Inspections

We offer CCTV inspections of Sewer Lines, Storm Drains, Culverts, Remote Lines, Manholes and Water Lines from 4” to 120". All of our video units are equipped with the latest technology to offer the finest picture quality available in the industry including the capabilities of digital capture in MPEG and JPEG format. Every camera has the ability to pan and tilt to provide the best view of defects and lateral connections.

Open Cut

Open cut is a method of pipeline installation that requires opening up the surface of the ground to the required depth for installing a pipeline. It is a traditional method that is still popular and is used widely for installation of sewer laterals and also for repair or replacement of main and lateral sewer lines.
Open cut excavations are cumbersome compared to open trenching methods, but in some cases, it becomes essential to open up the ground for repair as in the case of a line belly.
In the open cut method of pipeline installation, a trench has to be excavated for installing each piece of pipe. This method can be used for installation as well as the rehabilitation of pipeline and requires digging up the ground surface to the required depth (in case) of installation or digging up to pipeline depth (in case of rehabilitation) to expose the pipe. Once the work is complete, the dug out area is backfilled and the surface restored to the original condition as far as possible.
However, when the pipeline project is under a road or pavement, the open cut method can become a problem because the road will have to be cut open to gain access. This will, in turn, require closing the road to traffic and pedestrians until the work is complete.
Trenchless methods of construction such as directional drilling, pipe ramming, auger boring etc. and trenchless rehabilitation methods such as pipe bursting, thermoformed pipe, mechanical spot repair etc. do not require excavation except at the entry and exit points. This does not affect traffic and pedestrians because most of the work is carried out underground.

Point Repairs

Open cut trench excavation is the traditional and most popular method for sewer lateral sewer construction, repair, or replacement. Open cut trench excavation consists of excavating a trench for the manual installation of each “stick” or piece of pipe. This method is usually the least expensive method if the pipe is located under non‐pavement areas such as a front or back yard. The open cut trench method involves excavating down to and exposing the existing pipe so that it can be repaired or replaced and then backfilled. If the open cut trench excavation is located in a non‐pavement area the excavation can be backfilled with soil and surface vegetation restored by seed or sod. When the open cut trench excavation is located under pavement the existing pavement must be saw cut and removed, the excavation filled with granular backfill (compacted stone or sand to prevent settlement), and the pavement must be replaced and the end of the pipe repair or replacement. If a small section of pipe is being replaced a Fernco type coupling is used to provide a water‐tight connection to the existing pipe. A Fernco type coupling consists of a rubber sleeve that the pipe fits inside of and is fastened to the pipes using stainless steel bands that wrap around the outside of the sleeve.

Sliplining

Sliplining is a well-established method of trenchless rehabilitation. During the sliplining process, a new liner of a smaller diameter is placed inside the existing pipe. The annulur space, or the area between the existing pipe and the new pipe, is typically grouted to prevent leaks and to provide structural integrity. If the annulus between the sections is not epoxy, with each having distinct chemical resistance to domestic wastewater.
