SIGNS OF DAMAGED WALLS FROM SUBSIDENCE FOUNDATION CRACKS

Movement of foundations is hard to detect at its early stages because the movement starts below ground level which means you cannot see it happening until the initial shift of the foundation has taken place and then you will start to see the signs of subsidence which are:

• Cracks in walls and floors
• Cracks in bricks and masonry
• Walls bulging outward
• Gaps between floors, walls and ceiling
• Cracks above openings doors and windows
• Cracked moulding or architectural features
• Sticking of doors and windows
• Uneven floors

WHAT IS THE SOLUTION TO THE PROBLEM

To strengthen the masonry, high grade stainless helical bars are inserted into the bed joints. These act as new beams in the case of lintel reinforcement. Additional helical bars may also be installed vertically up through the soldier coursing to tie the bricks to the newly created beam.

• Wall stabilisation can be used to repair:
• Horizontal cracks
• Cracks to render coats
• Bowing walls

FEATURES AND BENEFITS:

• Easily fixed, even in weak materials
• Invisible when installed
• Very cost effective, saves having to install traditional lintels
• Versatile applications, designed for the job
• Cementitious based and therefore sympathetic to the original structure

THE PROCESS:

• A 65mm deep chase is made into the mortar joint to remove the bed joint
• After the chase has been cleaned out, a bead of grout or two-part epoxy resin is inserted
• Helical stainless steel bars are then cut to the precise length of the cut - to provide strength to the joint.
• The bars are then set into the chase and pushed into the grout. A second bead of grout is then applied.
