Kennet and Avon Canal Project Case Study
Resin injection used to control water ingress through a lock wall.
H2Ox were called in to control water ingress through a lock wall on the Kennet and Avon Canal.
Leakage had occurred through the canal wall and around an underground weir chamber adjacent to the lock. This manifested itself with flooding to a residential garden at the rear of the towpath, causing disruption to local residents.
Dye testing was used to identify the active flow paths using a green tracing dye.
H2Ox Engineers devised a method of drilling within the weir chamber and vertically through the canal wall to intercept the various flow paths. A fast reacting single component polyurethane was then systematically injected.
The flow paths to the gardens were sealed within days and within budget, preventing further leakage with minimal disruption.
