Manhole Rehabilitation
Polyurea manhole rehabilitation specialists in NSW – spray-applied protective coatings that extend manhole service life.
Manhole rehabilitation is an essential part of any council program and TriKing is here to help. With a system that covers all problems from tree roots to infiltration.
Our Process
Every access chamber rehabilitation follows a structured process: initial inspection and cleaning, infiltration repair where required, surface preparation, and final polyurea coating. Quality Assurance testing is conducted before handover.
Product
We use Tufflon-P80 pure polyurea – AS 4020 compliant for potable water contact, zero VOCs, and rated for continuous service at 120°C. This trenchless method avoids the cost and disruption of full manhole replacement.
Frequently Asked Questions
- How long does polyurea manhole rehabilitation last?
- Tufflon-P80 is rated for continuous service at 120°C and resists both H2S and microbial-induced corrosion. Specific service life depends on site conditions and coating thickness.
- Can manholes be rehabilitated without excavation?
- Yes. All work is done from inside the manhole or from the surface. No excavation or replacement of the existing structure is required.
- How does polyurea compare to epoxy for manhole coating?
- Polyurea cures in seconds and returns to service within hours. Epoxy typically requires 24-72 hours. Polyurea remains flexible and bridges cracks, whereas epoxy is rigid and can crack under stress.
- How quickly can a rehabilitated manhole return to service?
- Polyurea sets in seconds. In most cases a rehabilitated manhole can return to service within hours, the same day.
