Case Study – Culvert cleaning, patch repairs and lining

Highways

Culvert cleaning, patch repairs and lining save traffic chaos!

A busy dual carriageway had major defects in its surface water and land drainage. UKDN Waterflow were asked to provide reinforcement/repair solutions that could be delivered within traffic management systems at night between 10:00 p.m. and 4:00 a.m. Repairs were required to 30 different pipe runs and cleaning needed within various culverts.

Technique: Ambient cured epoxy resin impregnated structural patches.

Installation: Careful programming enabled 30 sections to be repaired in 10 shifts, including the associated over-pumping, high pressure jetting and robotic cutting to remove roots & concrete found within the pipes.

Capability: Local defects can be cost effectively repaired with patch systems. A variety of materials and resins can be used for different scenarios.

Benefits: Fast installation, short lengths, can be installed without flow control.

“We didn’t have much time to get these repairs done due to the traffic management restrictions. UKDN Waterflow worked closely with us and were able to get the repairs done within our existing traffic management arrangements, and much faster than we expected, saving us time and money.”
