The Structural Problem

The building was found to be deficient from the one that had been designed and remedial works were instigated by NHBC warranty. Consulting structural engineers were engaged to design the required compliant remediation works and Action Wall Ties were engaged to undertake the works.

The Structural Repair Solution

The remedial works involved the introduction of stainless steel support angles with horizontal soft joints and Sika CarboDur strengthening carbon fibre plates to concrete beam, together with remedial wall ties and bed joint reinforcement.

We removed the external brickwork skin exposing the concrete beam and prepared the concrete surface removing any ridges with a concrete planer, cleaned and primed ready for and applied Sika CarboDur structural strengthening system 80mm strips bonded with Sikadur 30 in accordance with manufactures and AWT methods. Thereafter, we installed stainless steel support angles and reinstated the brickwork.
