British Waterways
c/o Apex Construction
Foam injection of interstitial space between culvert and liner,
to prevent water loss from the canal.
The foam was modified for this project, so that its gelling time
was reduced, enabling the foam to go off before being flushed
out by the water pressure.
The foaming unit was taken across the canal, operating at a distance
of 30 metres from the compressor. See

Basingstoke Canal Authority
The Walls of Lock 20 on the Basingstoke
Canal were leaking badly, causing inconvenience to boaters and
costing the canal authority money in lost water.
GroundSafe loaded the foaming system onto a canal boat moved 7
locks down to Lock 20, inaccessible by other routes.
GroundSafe modified Uretek's Benefil RG30 foam reducing its gelling
time, then injected behind the lock wall using bespoke injection
needles. After locating a series of voids and foaming back to
the point of ingress, the leak was completely staunched. See

taken over by www.benefil.co.uk and are now branded under the
