Reconstruct a manhole without the hassle of excavation, traffic disruption, compaction, surface restoration and subsequent settling of the roadway, by using the Perma Form "manhole within a manhole" process. With Ameron's P.V.C. T-lock the Perma Form seamless concrete "manhole within a manhole" creates an impermeable barrier against chemical attack. The "new" manhole is then spark tested at 20,000 volts to ensure the impermeability of the plastic lining. We are so confident in this method of reconstruction that we provide a ten year guarantee.
