Subsidence & foundation repairs

Our Geotechnical Division provides clients with innovative solutions for subsidence and foundation problems. We specialise in non-disruptive ground repair options, Subsidence, containment, wash-out, low bearing capacity, solution features, clay shrinkage and heave. From our patented permeation grouting – injecting strengthening polymer into weak soil, remedial retaining wall schemes to traditional mass concrete underpinning, piled rafts, screw piles and ground anchors.

Subsidence repair and remediation

Our deep understanding of soil mechanics and building behaviour allows us to choose practical and cost-effective methods of repairing compromised foundations.

As long-standing members of ASUC (Association of Specialist Underpinning Contractors) we provide insurance backed defects guarantees on all underpinning and structural repairs. 12 years – Defects Insurance Guarantee (DIG) covering structural and underpinning works.

Polymer injection for ground strengthening – Permeation Grouting using our world-wide patented ReFORCE system – a polymer injection system for ground strengthening. It is currently the only polymer ground injection system that carries a defects guarantee with the designed and installed system. We provide a Nationwide, fast, economic, safe and sustainable service for ReFORCE piling and ground stabilisation.
Traditional underpinning whether for subsidence, basement construction, increased load bearing or for structural alterations to buildings STRESS’s hugely experienced and qualified underpinners work safely, efficiently and neatly and always in accordance with ASUC guidelines.
Screw piling often due to awkward access issues with remedial underpinning schemes screw piling offers a sensible, safe and low impact solution to foundation support.

Retaining wall problems STRESS’s geotechnical engineering capability allows us to find and design innovative and economic solutions to failing retaining structures. Ground anchors and wall stiffening can obviate the need for expensive and disruptive wall renewal.
Solution features a common occurrence in chalk sub-strata which can dramatically affect buildings, roads and structures. We design and install sustainable capping systems which negate the standard methods of filling with cement-based materials which are carbon heavy.
Ground stabilisation For safe, economic basement construction using the GEOInnovations ReFORCE system. Reduce risks of party wall movement and ground water problems
