Specialist Helifix crack stitching and wall tie replacement for period properties and listed buildings throughout London. Minimally invasive. Over 35 years of experience.
London Brickwork Repointing provides specialist Helifix remedial works for cracked masonry, failing wall ties and structurally compromised brickwork throughout London and the Home Counties. With over 35 years of experience working on period and heritage properties, our team carries out Helifix crack stitching and wall tie replacement using approved stainless steel systems that stabilise masonry while preserving the original appearance of the building.
Helifix systems offer a minimally invasive solution for a wide range of structural masonry problems. Rather than resorting to disruptive or expensive rebuilding, Helifix reinforcement can stabilise and repair cracked or failing brickwork from within the wall — leaving the external appearance largely undisturbed.
Helifix is a system of helically wound stainless steel bars and fixings designed for the repair and reinforcement of masonry structures. The bars are inserted into small-diameter holes drilled into the mortar joints and bonded in place with specialist resin or grout. Once installed, they are largely invisible from the exterior of the building.
The system is widely specified by structural engineers, conservation architects and local authorities for remedial works on period and listed buildings because it is effective, durable and minimally invasive.
Cracks caused by settlement, subsidence or thermal movement can be stabilised using Helifix crack stitching bars installed across the crack line.
Corroded or failed wall ties in cavity wall construction can be replaced with stainless steel Helifix remedial ties without removing the external brickwork.
Walls that have begun to bow or bulge due to wall tie failure or loss of structural integrity can be restrained using Helifix fixing systems.
Cracking above doors and windows caused by failed or corroded lintels can be addressed using Helifix reinforcement systems.
Leaning or cracked chimneys can be reinforced and stabilised using Helifix systems to avoid full rebuilding.
Helifix is widely approved for use on listed and conservation area buildings where invasive repair methods are not permitted.
We inspect and assess the cracking, identify the cause and determine the appropriate Helifix specification.
Working from our assessment and any structural engineer’s reports, we specify the correct Helifix products and fixing pattern.
Small-diameter holes are drilled into the mortar joints at the specified positions — bricks are not cut or removed.
Helifix stainless steel bars are inserted and bonded in place using specialist resin or grout.
Drilled holes and disturbed mortar joints are repointed to match the surrounding brickwork.
