Void filling

Mineshafts, tunnels and caves are all suitable applications for Benefil

Shafts, tunnels and caves are all readily filled. Benefil requires pushing and does not flow, therefore only simple forms of containment or shuttering are required. Completeness and lightness of fill can also be important. Benefil is simple to remove and recyclable, so, If later required, access can easily be reopened.

Benefil can fill any size of void. It is ideal for filling pipelines and conduits. Residual fluids are forced ahead and expelled. An abandoned pipeline can be filled completely, either uphill or downhill, even if only one end is accessible. When used to fill the interstitial (annular) space formed by relining, the new ‘slipline’ will not collapse or float when being installed. Soil loss due to infiltration can be corrected by filling resultant voids from above.
