Cavity wall stabilisation

Technitherm^® is for use in restoring the structural stability of existing external cavity walls with masonry inner and outer leaves in which the conventional wall ties have corroded. This includes clay and calcium silicate bricks, concrete blocks, natural and reconstituted stone blocks. When injected in liquid form into a cavity wall, the foam expands, fills and bonds to the internal wall surfaces, stabilising the wall across the entire area. It is also suitable for walls constructed with defective mortar as well as tie failure. Injection grades are available with Board of Trade approval for marine and buoyancy applications.

The system is BBA certified, Certificate no. 97/3426. MPI is Building Register and CHAS accredited.
