Wall Stabilisation

In addition to remedial wall ties Peter Cox now has a range of additional services for repairing structural faults in walling masonry.

Replacement Cavity Wall Ties

Horizontal cracking along mortar joints is a typical sign of underlying wall tie corrosion, a problem resulting from factors such as inadequate or sub-standard galvanising, chemical corrosion (e.g. by black ash mortar) or extreme exposure ( e.g. marine locations).

Peter Cox surveyors use specialist equipment including metal detectors and endoscopes to examine and determine the condition of the ties. Where needed high quality austenitic stainless steel replacement ties are installed, fixed either mechanically or with resin.

Where applicable, treatments carry our 20 year long term guarantee.

Structural Anchors

Peter Cox technicians are approved installers of the
Cintec system of cementitious grout masonry anchors. This technique can be used for stabilising masonry walls, whether of solid, cavity, hollow pot or rubble filled construction.

It is particularly effective in weak substrates, is largely invisible after installation and is sympathetic to the original structure, making it acceptable to heritage authorities.
 

Brick Stitching

To stabilise cracked brickwork helical stainless steel
rods are installed in the mortar bed joints.

This redistributes tensile loading to minimise further
crack development.

Lateral Restraints

To counteract movement in external walls stainless
steel bolts are installed from the outside to tie them
back to the internal floor joists.

Resin, mechanical or cementitious systems can be utilised for this.
