Injected under sunken concrete floors or driveways, Benefil firstly fills any voids and then, with even pressure, raises the concrete back to its correct position.
The process is carefully controlled and guided by laser. Floors and other structures threatened by erosion (eg flood damage or large washout caused by a broken water pipe) can be quickly stabilised, re-supported and/or re-levelled. Lost soils are replaced by Benefil. There is usually no need to vacate premises. Most jobs can be done in one day.
