TRENCH‑LESS SEWER REPLACEMENT (PIPE BURSTING)

Pipe bursting is the most advanced and affordable way to replace damaged sewer lines. Instead of digging up your entire yard, we pull a brand‑new pipe through the existing line using 30 tons of pulling force.


Why choose pipe bursting?

  • Brand new HDPE pipe installed without the mess of trenching
  • Saves money compared to traditional excavation
  • Preserves landscaping and property — trees, plants, concrete, and parking lots remain intact
  • Fast and efficient process with minimal disruption


How it works:

  1. We excavate a small pit in the street and another in the basement.
  2. HDPE pipe is fused together to the correct length.
  3. A cable is run through the old sewer and attached to our bursting machine.
  4. The machine pulls the new pipe through the old line.
  5. Connections are made and pits are backfilled.

We pulled a new sewer line through old orange berg and clay tile pipe using pipe bursting method. We dug a small hole and avoided most of the parking lot.

How it works?

We start with excavating a pit in the street and a pit in the basement. After both are safely excavated and the holes are ready, we fuse 4" HDPE pipe together until we have the right length. Next we run the cable through the sewer and hook it up to our bursting machine. Then the machine uses 30 ton of pulling force to pull the new HDPE pipe through the old sewer. Now we make our connections and backfill the holes.

Pipe Patch Repair (No Dig)

When excavation isn’t ideal, pipe patching offers a no‑dig solution. This resin‑based product is inserted into the damaged section of pipe and cured in place, forming a smooth, round patch that bonds to the existing pipe.

Advantages of pipe patch repair:

  • Non‑excavation method — ideal for sensitive areas
  • Durable resin patch that extends the life of your sewer line
  • Cost‑effective alternative to full replacement
