Introduction: Drainforce were tasked to rectify defective pipe UTX drain and headwall that was becoming unstable along a LUL banking. The pipe in question was a Surface Water Pipe 900mm long 25m in Length.
Drainforce completed Topographical Surveys and Designs to LUL standards for both the UV Lining and Structural Headwall taking into account bank Stabilisation.
After Pre-Site Meetings and planning a Method Statement and Safe Working System was confirmed and signed off.

Before Works commenced Pre Site Meetings and Briefing’s were completed Daily ensuring the details of the Method Statements were filtered through and that Daily Dynamic Risk Assessments were completed monitoring Weather and any variable conditions.

Drainforce arranged access to the site through land agents. We cleaned the culvert with recyclers which have a high volume of water ideal for removing large volumes of silt from the culverts without the requirement to pull off and fill up with water allowing for all works to be completed during tight time scales.

Once the lines had been cleaned Drainforce set up over pumping and delivered the 5t liner to site though specialised track cranes.

The Liner was winched into position and cured with our Mega UV Rig. The liner was manufactured with an additional outer back for free in Air Lining.

The purpose of this was to extend the liner past the existing head wall to allow the new head wall to be built around the Liner while keeping the old headwall in position and not effecting the stability of the bank.
