Structural cracking, horizontal cracking of bed joints, bowing brickwork, and cracked lintels are all signs that a building is undergoing movement of some description. Causes can include wall tie failures, lintel failures and even natural causes such as tree roots affecting the foundation. Correctly diagnosing the exact cause is essential for suitable remedial work to be carried out.

Helibeam

Preservation Treatments is an approved installer of the Helibeam System. The Helibeam System uses pairs of long HeliBars bonded into mortar to form deep masonry beams that reinforce and stabilise existing masonry while redistributing the structural loads.

It provides a rapid, cost-effective means of restoring structural integrity to buildings and structures where the masonry has failed and lost its load bearing capabilities. In combination with other Helifix ties and fixings it provides a comprehensive, reliable and economic system of repair and stabilisation for many commonly occurring structural faults.

Crack Stitching

Helifix Crack Stitching repairs and stabilises cracked masonry using stainless steel HeliBars bonded into cut slots with HeliBond grout for a quick, simple, effective and permanent solution. Cracked masonry is best stabilised by bonding HeliBar stainless steel bars into suitable bed joints or cut slots. Tensile loads are redistributed along the masonry to minimise further developments of the crack which may occur with simple injection methods.
