Large Diameter Trenchless Pipelining
Rehabilitate your building’s sewer pipeline network with our large-diameter trenchless pipelining method. Aqua Pro can quickly restore old failing sewer lines that are 8″ to 24″ in diameter on the same day in most cases. The trenchless pipelining process for large-diameter pipelines involves accessing the host sewer line through a manhole or open pit. The repair is made to the host mainline without digging or excavating the existing line. This repair process is completed without making a trench or excavating a road.s
Benefits of large-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
Repair 8"-24" Sewer Pipes
Trenchless pipelining: Before and after a large-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.
Large-Diameter Trenchless Pipe Rehab (8" to 24") in Miami
Eight-inch to twenty-four-inch pipe usually means commercial property, multifamily building, HOA infrastructure, or city-side sewer main. The cost and disruption of trenching at this scale — closing parking lots, tearing up roadways, shutting down buildings — is what makes trenchless rehab the only practical option for most owners.
How Large-Diameter CIPP Lining Works
We use the same Cured-in-Place Pipe (CIPP) process as residential lining, scaled up for larger pipe. A resin-saturated liner is inverted or pulled into the host pipe, expanded with air or water pressure, and cured with ambient air, hot water, or UV light depending on the project. For 8″ through 24″ mains we typically run UV-cured lining because the cure is fast and the resulting pipe is dimensionally consistent across long runs.
On the largest diameters we also use pipe bursting where structural failure has gone too far for lining. Pipe bursting fragments the host pipe and pulls a new HDPE pipe through the same path. Useful when the existing pipe has lost its shape but the alignment is still serviceable.
Where Large-Diameter Rehab Comes Into Play
Common projects include: condo and apartment building sewer mains under the foundation; commercial property collector lines under parking lots; HOA shared sewer lines connecting multiple units to one city tap; restaurant grease line rehabilitation; and municipal sub-main repair where the city allows private contractors.
What a Large-Diameter Trenchless Project Involves
We start with a full CCTV survey to document the existing pipe condition and grade. Heavy hydrojetting clears scale, debris, and grease so the liner has clean substrate to bond against. The liner is then installed and cured under controlled conditions, with continuous video monitoring during cure. After cure we cut in any service connections from inside the lined pipe and do a final inspection.
