Are you observing pipe deterioration caused by years of usage, increased line stress, or accidental strikes? Repair defective isolated sections of pipe without digging!
A clean sewer or sanitary line makes it easier to repair a pipe trenchlessly. The pipe liner will adhere to the wall without any issues in a clean pipe. Before trenchless pipe repair, our team will use hydro jetting to remove blockages, build up, and grease.
If the pipe is located within a roadway, traffic control services will can be provided by Trinity Subsurface, LLC for site safety.
A robotic crawler traverses the cleaned sewage/storm pipe to determine where the pipelining will be placed.
CCTV pipe inspection is an efficient way to find, pinpoint and mark pipe defects including cracks, corrosion, and infiltration.
Inspecting the pipe can determine the exact amount of materials needed for new trenchless pipe lining.
Trenchless pipe lining materials include polypropylene lining, felt, and fiberglass for a strong hold. A two-part epoxy is mixed and a generous coat is applied to the pipe liner to cure the material to the wall of the pipe.
The pipe liner is wrapped around a packer, which is an inflatable tool that can expand to the size of a pipe.
The pipe lining packer with the liner is positioned where in the section of pipe with defects. Once in the desired location, the packer is inflated to the size of the pipe.
The inflatable packer allows a 2 1/2 inch flow through for sewer system while the liner is inserted. This allows for the continued use of the system without major disruptions.
The trenchless pipe liner curing process takes between 3 and 4 hours. The packer remains inflated until the repair is complete.
Once the epoxy is cured to the pipe, the packer is removed. A water-tight and permanent seal is created from a sectional point repair.
The pipe is restored to its original integrity. The pipe is then flushed and televised a second time to confirm the repair is effective.
Our pre and post-pipe inspection report can examine damaged and repaired pipes. Need more information on your sewers and pipes? Reach out for a CCTV deliverable sample to see how user-friendly reporting can be helpful for contractors, engineers, and more.

Sectional point repair is a trenchless solution to fixing damaged pipes. There is no digging or excavation necessary as the pipe is repaired from the inside out with an interior lining. Trenchless pipe repairs restore structural integrity by sealing joints, cracks, or missing pipe sections and eliminates root intrusion.
A sectional point repair focuses on a single section of the pipe rather than the entire length of the pipe. This can help target specific areas or damages where a full-length CIPP pipe repair may not be necessary.
Determining the best option for your needs can involve inspecting the pipe prior to a repair.
Sectional point repair is the most cost-effective solution for municipalities and commercial facilities with isolated sewer line problems. Not only does sectional point repair prevent costly and unnecessary repairs, but it can also be completed as quickly as one day.
A trenchless point repair forms a structural, permanent waterproof repair that seals all types of pipe against infiltration and exfiltration.
A finished pipe point repair will end up stronger than the original pipe as reinforcing material for a long-lasting repair. The repair has a superior bond to the existing pipe equally in wet or dry conditions.
Pipe lining material is very thin, but strong. As a result, there is very little shrinkage compared to the original diameter of the repaired pipe to keep up with flow capacity.
Our trenchless point repair system can be used equally well in warm or cold climates.
