About Us
Trenchless Pipe Repairs That Last
Leaking underground assets cause ground movement, effluent discharge, sinkholes, and added pressure on wastewater treatment plants. Left unrepaired, a single point of ingress can escalate into a full structural failure.
Precision Pipe Technologies provides trenchless patch repair, grout injection, and leak sealing services across Perth and Western Australia. Using high-pressure grout pumps and cementitious plug products, PPT seals groundwater ingress without excavation — protecting roads, landscapes, and live infrastructure.
Whether the issue is a crack, hole, joint displacement, or root intrusion, our trenchless repair methods deliver a structurally sound, long-term result with minimal surface disruption.

The blockage keeps coming back
Repeat blockages mean something was missed the first time. We jet the full line and inspect with CCTV to find the root cause — not just the symptom.
I need the pipe cleared without shutting down the site
Our truck-mounted systems work from above ground through existing access points. Most commercial jetting jobs are done in hours, not days.
The last mob couldn't tell me what was actually wrong
Every job gets CCTV footage and a written report. You see exactly what was inside your pipe and what condition it is in.
I need documentation for council or insurance
We provide timestamped footage, condition reports, and compliance documentation. Council, body corporate, or insurance — covered.
Efficient drain and sewer cleaning for councils and commercial networks. Removes blockages and restores flow.
Accurate diagnosis before any pipe work — honest, documented assessments every time.

Trenchless pipe repair is a method of fixing damaged underground pipes without excavation. Techniques include CIPP patch lining, grout injection, and cementitious sealing — all performed through existing access points. This avoids digging up roads, footpaths, and landscaping while delivering a structural repair rated for 50+ years.
Trenchless patch repairs address cracks, holes, joint separations, root intrusion, and groundwater ingress. PPT repairs pipes from 50mm to 1200mm diameter across stormwater, sewer, and pressure main assets.
A high-pressure grout pump injects cementitious material into and around the pipe defect. The grout fills voids, seals cracks, and stops water ingress — stabilising the surrounding soil and preventing further erosion or sinkhole formation. The procedure is performed without excavation through existing access points.
Trenchless patch repairs and grout seals typically last 50+ years depending on host pipe condition and operating environment. The repair creates a bonded structural seal that prevents further ingress and root penetration.
