    Case Study
    • Benefil®
      British Waterways c/o Apex Construction
      Benefil injection of interstitial space between culvert and liner, to prevent water loss from the canal. The Benefil was modified for this project, so that its gelling time was reduced, enabling the Benefil to go off before being flushed out by the water pressure.
      The Benefil Polymer unit was taken across the canal, operating at a distance of 30 metres from the compressor. Canals - Benefil case studies


    Case Study
    • Benefil®
      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 polymer unit onto a canal boat moved 7 locks down to Lock 20, inaccessible by other routes.
      GroundSafe modified Uretek's Benefil RG30 /Benefil 3000 reducing its gelling time, then injected behind the lock wall using bespoke injection needles. After locating a series of voids and working back to the point of ingress, the leak was completely staunched.

Suter Pier, the central hub of the Port, had been founded on mixed hardcore fill, retained by a high perimeter seawall. By 2004 time and tide appeared to have washed out significant volumes of the fines from between the rocks.

        This had caused extensive voiding and had developed the risk of possible slab failure or collapse due to the very heavy storage loads put on the shed floor.

        The Construction Manager and Project Engineer for the Port accepted the tender of Grouting Plus Solutions to restore the support base for this enormous (over 5,000 m2) storage facility. Benefil® was the product selected to fill large interconnected voids under the floor slabs adjacent to the seawall.
        The Suter Pier project saw Grouting Plus Solutions inject Benefil® under approximately 1,000 m2 around the shed perimeter and the work was completed over a period of ten days in mid-2004. 210 m2 of Benefil® were injected, while the shed remained fully operational with various contents piled high. That included mountains of stock feed.
        All the time ships were berthing, unloading and loading at the cargo wharves that run along each side of Suter Pier Shed. There was virtually no interruption to the workings of the Port.
        For this work Benefil® was produced at a relative gravity of 50 kg/m3 to suit the high floor-loading requirement. (The density can be varied to suit other tasks: relative gravity of 22 kg/m3 suits the filling of fuel tanks that are to be made safe for abandonment and relative gravity of up to 70 kg/m3 may be produced to support heavier structures.)
        Combining economy, ease of application, lack of disruption and engineering strength, Benefil® was the right answer to the demands of this Townsville Port work.
