Advantages of Resin Injection in Ground Stabilisation
HBT are proven specialist in resin injection technology. By careful injection under low pressure, the resin flows into the ground via lances, the resin then reacts to a pre-determined set and expansion rate, then further permeates the soil throughout the reaction process. The resins deployed are ideal for use in sensitive environmental areas such as canal embankments due to their European drinking water approval . Once the resin has reached its maximum expansion the resins will continue to cure, forming a uniformed stabilised subbase. The cohesive nature of the ground improvement controls water and fines within the soil allowing for the installation of underpins and foundations where required.
Injection lances are driven using our specialist lance installation technique up to a depth of 12 metres where required.
Assurance of placement of the injection resin is achieved by the latest lance extraction technology ensuring a uniform fill is achieved forming a stabilised load bearing and an increase in cohesive properties.
As part of our quality assurance process HBT provide Ground penetrating radar surveys, or alternatively a ground stiffness surveys using the latest technology.
Throughout the ground stabilisation process installation we ensure our strict quality assurance procedures is adhered to with temperature, volume of fill, product batch numbers all being recorded throughout the process.
For further information please request our ground stabilisation case studies on how we have used our resin techniques on live projects and how they can help you.
A ground floor slab is designed to distribute loads to the immediate sub-base and fill. If the material is inappropriate or is poorly compacted it will consolidate, resulting in the formation of voids, usually immediately below the slab. Consolidation of the fill material is an essential first step in repairing and reinstating the flooring. HBT Floor and slab Lifting method acts directly on the foundation by filling voids and re-compacting the more superficial layers of fill, and finally by applying thrust to the underside of the floor slab, lifting the floor slab to the original or desired level.
In some cases, it is necessary to complete the job with the HBT deep injection process if there is poorly consolidated fill material at depth.
