Supermarket Raised 180mm & Re-levelled

JOG integrated computer grouting was employed beneath the load bearing elements from outside the building in daytime.

Uretek engineered expanding structural resins were injected beneath the internal floor slabs and footings, outside of the normal trading hours.

The building’s construction, distribution and degree of lift required, and mitigation against any new stresses being imposed on the structure throughout lifting, were all considerations in the design of the injection array.

Injection locations were installed via 40mm Ø penetrations through the footings.

During each sequence of hydraulic lift, only a relatively small amount of material was injected at each pass, at each of the locations, for gentle, even lifting of the whole structure. The greatest lift in a single area was180mm.

Uretek Resin Injection

Expanding engineered resins were injected beneath the internal floor slabs first to fill voids and then to raise them. This was done outside of the store trading hours through 16mm Ø holes to minimise impact on the client’s business. The supermarket maintained normal trading throughout the lifting works. The project was entirely successful in restoring levels and eliminating structural stresses.
