The last thing a warehouse operator wants is for the facility to have to close while repairs are carried out to settled floor slabs, with all the costs associated with such disruption. Yet the use of resin injection processes from specialist contractor Uretek UK Ltd allows the strengthening of floors with minimal disruption.
Repair is carried out by the injection of liquid resin through 15-20mm diameter holes drilled through the floor slab. The material immediately expands to fill any voids, and then exerts force in an upwards direction to gently lift the flooring. Because of the rapid set-off time of the resin, the slab lifting method is highly accurate and controllable, with movement being carefully monitored by laser level to avoid overlift.
With the Uretek method, it is possible to either lift the flooring, or to simply strengthen the sub-base. The geopolymer resin offers the benefits of significantly increasing load bearing properties of the fill and sub base, long-term stability, thermal insulation and impermeability.
Only 10% of the weight of concrete, the material does not add weight or stress to the surrounding soil.
While the ground strengthening is carried out, work can continue in the facility, with the process being applied to one small area at a time and the rest of the commercial operations proceeding normally. No dust or mess is created, and there are no excavations. The Uretek material achieves 90% of its strength within 15 minutes, enabling areas to be re-used immediately following treatment.
Mezzanine floors are seen as an attractive option in an economically constrained climate, as they allow additional commercial space without the expense of building a new facility. By the same principle, strengthening the ground for mezzanine columns without having to sacrifice time or retail opportunity makes polymer injection an attractive option.
Uretek’s Slab Lifting, Deep Injection and PowerPile systems are available for the optimum results, offering the best and fastest strengthening options for different ground conditions.
Even warehouse racking doesn’t need to be taken down while polymer injections are carried out.
Work is backed by a standard 10-year materials guarantee, and the Uretek method is now widely accepted by insurers, local authorities and consulting engineers.
