Manhole Rehabilitation Using Spray-In-Place Pipe Method
In contrast with the conventional Manhole Rehabilitation works of man-entry plastering and grouting works, we provide a non-man-entry alternative method of Manhole Rehabilitation – the Spray-In-Place pipe method, which does not require stopping of the existing flow within the pipes. Among its advantages is increased resistance to leakage, fully adhesive to concrete, masonry & metal texture, anti-corrosion, aging resistance, durable and fast curing.
