A safer, environmentally friendly alternative with minimal disruption.
Grouting Plus Solutions provide lightweight, engineering filler grout that can be used to safely fill large voids and disused underground tanks and pipes.
It is economical, environmentally friendly, lightweight and versatile and can be poured, pumped or injected into holes, voids and interstitial spaces – upwards, downwards or laterally over long distances.

Recognised as the preferred method by the industry for decommissioning of petrol, chemical, LPG underground storage tanks.
A safer, environmentally friendly alternative with minimal disruption.
Benefil absorbs any residual hydro-carbons, making tanks safe from explosion. Benefil doesn’t generate heat during production and curing.
Benefil is extremely lightweight compared to concrete slurry and sand
2,300kg m3 vs 20kgs m3
Expanded Benefil can be induced to travel up to 100 metres. It is unique for filling pipelines and conduits.
Residual fluids are forced ahead and expelled. Soil loss due to infiltration can be corrected by filling resultant voids from above. And an abandoned pipeline can be filled completely, even if only one end is accessible. Uphill or downhill, it makes no difference – Benefil won’t run out!
When Benefil is used to fill the interstitial (annular) space formed by relining, the new ‘slipline’ will not collapse nor float when being installed.
Shafts, access tunnels and wash-aways are readily filled. Benefil requires pushing and does not flow, therefore only simple forms of containment are required.
Completeness and lightness of fill can also be important. It can be removed and recycled to re-open access, if later required.
Floors and other structures threatened by erosion (e.g. flood damage or large washout caused by a broken water pipe) can be quickly stabilized, re-supported and or re-leveled.
