100mm
Our smaller robots are extremely proficient in traversing numerous bends where other equipment may struggle
Concrete Obstruction in Drain Requiring Removal
Our client called us urgently requesting attendance to a new build site (student accommodation). The site had experienced mass flooding as a result of concrete obstructing the base of the main SVP. The SVP was situated in the centre of the building and approximately 2 metres deep meaning an excavation would prove extremely costly and disruptive.
High pressure Concrete cutting within the drain
Concrete Removal - We attended with our Streicher CL50 unit which is best suited to small diameter pipework. Working from the internal chamber (this was no issue with our portable equipment), we successfully broke up the concrete before this was removed via high-pressure water jetting.
Concrete ingress extraction from inside the drain
Utilising a range of specialist grinding and milling heads, along with our specialist 225mm cradle, we managed to remove the protruding rebar and allow sufficient cleaning/surveying of the line. Minimal disruption was caused by employing our cutters to provide an effective solution. A lot cheaper than excavating!
We can deploy extremely high powered, 23,000 psi jetting if required for cutting and extracting large lumps of concrete found in drains. This is a precision process guided with a CCTV drain camera and fires out water at such high pressure, it breaks the concrete up and flushes it down the line and can be captured and removed from the drain. This system for reinforced concrete removal is far less intrusive than site excavation, a No Dig solution is also more cost effective with excavation often complicated, messy, and problematic.
