Small Diameter Trenchless Pipelining
Rehabilitate your building’s sewer pipeline network with our small-diameter trenchless pipelining method. Aqua Pro can quickly restore old failing sewer lines that are 2″ to 6″ in diameter on the same day in most cases. The trenchless pipelining process for small-diameter pipelines involves accessing the host sewer line through a cleanout or open pit. The repair is made to the host pipeline without digging or excavating the existing line. This repair process is completed without making a trench.
Benefits of small-diameter trenchless pipelining
- No treneching to remove the old sewer line
- No disruption to neighboring landscaping or concrete slabs
- No downtime in day to day operations at the facility
- Same day repair in most cases
- Longer liftime of CIPP liner than existing host pipe
- Completely sealed system from repair end to end
- Seamless, Jointless repair with CIPP liner
- Structural repair

Trenchless pipelining: Before and after a small-diameter trenchless pipe repair. Obstructions and defects are removed from the old host pipe prior to lining with a robotic cutter. Observe the new CIPP (cured in place) pipe liner on the right side of the illustration.
Small-Diameter Trenchless Pipe Repair (2" to 6") in Miami
Most residential drain and sewer lines in Miami homes fall in the 2-inch to 6-inch range. That covers branch drains under bathrooms and kitchens, vertical stacks, and the lateral line that runs from the house out to the city main. When any of those pipes fails — usually corroded cast iron in homes built before 1975 — the traditional fix was to dig up the floor or yard and replace the section. Trenchless lining solves the same problem without the excavation.
How Small-Diameter CIPP Lining Works
We feed an epoxy-saturated felt liner through your existing pipe using a small access point — typically a cleanout or a single break-in point at one end of the run. The liner is inverted into place, expanded against the host pipe walls, and cured. The result is a new structural pipe formed inside the old one, with no joints, smooth interior walls, and a 50-year design life.
For 2- to 6-inch lines we use felt or fiberglass liners cured with either hot water or ambient air, depending on the run length and bend geometry. Cure times for residential runs are typically two to four hours, after which the line is back in full service.
When Small-Diameter Trenchless Is the Right Call
We recommend small-diameter trenchless repair for: cast iron drain lines with channeling at the invert; clay lateral pipes with root intrusion at multiple joints; sections of pipe with cracks but otherwise intact alignment; situations where excavation would require breaking up floors, lifting tile, or removing landscaping. We do not recommend it for fully collapsed pipe, severely belly-shaped lines, or pipes that have deflected out of alignment — those need to be rebuilt.
What a Small-Diameter Trenchless Job Looks Like
Most residential jobs involve a sewer camera inspection to map the line, light hydrojet cleaning to remove buildup, the lining installation itself, a post-install camera inspection to confirm the new liner, and a flow test. From the time our crew arrives, an average single-family home job runs four to eight hours.
