    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.

    Aberdeen County Councel
    Badger sets beneath a stretch of the busy A97 through Aberchirder had been exacerbating subsidence problems and endangering the creatures.
    A lengthy campaign by locals and environmentalists had lead to the re-homing of the badgers in a purpose built set, nearby.
    GroundSafe injected RG30 Bacel® Hardfoam into the abandoned sets filling the voids completely , consolidating the soil and preventing further inhabitation.

    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 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.

    Perco Engineering c/o Barhale c/o Anglian Water
    The client had slip lined 660 metres of 450 mm sewer with 250 mm of HDPE pipe.
    The client had secured 63 mm HDPE pipes into the headwalls around the annulus created between the two pipes, creating injection and vent points at every inspection manhole.
    GroundSafe injected up to 100 metres from each manhole.
    Because Bacel® Hardfoam does not cause pipe floatation the sewer remained live throughout the operation, with no need for spiders.
    650 metres were grouted in one day.
