Manhole Mortar Sprayer: Reline 600–1800 mm Manholes from Inside, No Digging

Reliance Trenchless Technology · English · Oct 20, 2026

The mortar sprayer mixes mortar on site, pumps it down the hose and sprays it onto the manhole wall while the winch lifts the head from bottom to top.

The 600–1800 mm spraying diameter, 0.10 m/s winch speed and 40 bar delivery pressure come from the published specification table. Confirm the pump, spray head and material for each manhole.
