Trenchless Systems

While many businesses choose to trench their backyard and damage and foul the sewer line, our Trenchless Systems is the most economical, effective, safe and durable solution.

Our technicians trained with the Trenchless Systems technique guarantee the quality of service, peace of mind and less headache for you.

This method allows us to add new tubes at the same time as removing the old ones. Our technicians only have to dig an entrance and an exit for the passage of the equipment.

Understand the step by step of this technology, capable of reducing costs between 30 to 40%

Step 1: Video inspection of the sewer pipe.

With our camera inserted in the pipe through a cable, we carry out an inspection to assess problems if it is feasible to apply the Trenchless Systems technique.

Step 2: Cleaning.

Once we identify if applying Trenchless Systems is the right approach to make, our technicians will carry out the internal cleaning of the pipes with the hydroblaster and/or mechanical methods.

Step 3: Calibration tube.

After cleaning the pipes, our technicians will insert the new coating that will be inflated inside the pipes, and after the curing time this coating will be the new structure of the sewer pipes.

Step 4: Applying Epoxy.

Now our technicians will prepare the epoxy to be applied to the inner lining of the ceiling. Through the “Wet-Out” process, all felt fibers in the coating are saturated with epoxy.

Step 5: Charge Inversion Tank.

After the epoxy is cured then we will use the inversion tank to blow the coating into the tube.

Step 6: The tube is coated.

The Inversion Tank is filled with compressed air which forces the casing out of the tubes through the Inversion Head.
After a few hours, the coating was cured in place to form a new tube.

Step 7: Final inspection.

To ensure that the entire process was carried out satisfactorily, we will carry out an inspection with our camera inside the new pipes, and if any pipe meeting is obstructed by the Trenchless Systems technique, we use our robotic reintegration equipment to unclog any connection that may have been sealed. during the process.

Using the Trenchless Systems technique may save up to 40% of your budget!

1How long will a sewer line last?

How long a sewer will last depends on a number of factors including the pipe material, proximity to trees, etc. If your sewer line is more than 40 years old, it may need replacing. Even if the home is newer, its plumbing may be connected to an older sewer pipe. Even if your home is newer, regular video sewer line inspections are good insurance. By inspecting the pipes for bulges, joint failures, cracks and tree root intrusion, you can prevent a costly sewer line backup and extensive repairs.

2Does homeowners insurance cover sewer line damage and repair?

Most insurance policies do not cover repairs to sewer lines caused by gradual wear and tear. Before problems occur, check your homeowner’s insurance policy to see if it covers sewer pipe repair or replacement. Some insurance companies will add a sewer and drain endorsement to your policy to cover losses related to a sewer line backup, to cover damage to your home.

3What causes sewer line damage?

The most common problem with older homes built prior to 1980 is damage from tree roots that have invaded the joints of the pipes. Other causes include acts of nature, accidental damage from digging to close to the pipe, and inevitable deterioration to the pipes over time.

4Can I delay my sewer pipe replacement by cleaning out the pipe myself?

Cleaning out your own sewer line with drain cleaner or a snake or auger may make your sewer line problems worse.

If your sewer line has partially or completely collapsed, pouring drain cleaner down it will not improve the flow of wastewater. Instead, the caustic chemicals will sit in the pipe and dissolve it. This will result in the chemicals penetrating the ground beneath the pipe.

Also, if you turn on the water to flush the pipe after pouring the drain cleaner, the water along with the chemicals can back up, causing the potential for personal injury and additional damage.

If you try to use a commercially available snake or auger that you purchased from your local home improvement store, it may not be long enough to reach the clog. If the clog is being caused by heavy root infiltration or collapsed pipe sections, the auger will not be able to clear the sewer line.

Instead of trying to clear the pipe yourself, it is always best to consult with a professional plumber.

5 What is a traditional pipe replacement?

A traditional pipe replacement involves digging a trench along the entire length of the sewer line. If sidewalks, driveways or other structures are over the sewer line, they must also be excavated. Once the trench has been dug, the old sewer line is removed and a new sewer line is inserted into the trench and connected to the system.

The plumbing company will typically fill in the trench after the work is complete, but the homeowner or business owner is responsible for replacing any sidewalks, driveways and additional structures.
