Our Arch & Lintel Repair Solutions

More often than not, builders will dismantle broken arches or tear out entire walls to repair lintels. This turns the arch and lintel repair process into a long-winded, disruptive and expensive one. It’s a process that leaves huge, gaping holes in your home’s structure AND wallet. Worst of all, you’ll probably need to leave the house for an extended period of time.

Rather than turn your life upside down, our technicians and structural engineers look for the true cause of your home’s broken arches and lintels before doing anything. By diagnosing issues properly, they’ll implement a cost-effective, permanent arch and lintel repair solution utilising our proprietary, HelicalBar™. This process usually doesn’t take more than a day and you can even stay at home while we work.

Arch Repair Method

Repairing and reinforcing brick arch structures

We begin this arch repair method by removing old or even corroded mortar from the arch’s bed joint. We flush out any leftover debris with clean water, then place a single 6mm HelicalBar™ into each slot on both sides of the arch. Using GroutSet, we make the HelicalBar™ follow the complete curve of the arch for extra support.

To stabilise the first course of brick further, we install a 6mm brick perp anchor or Fast-Fix at 220mm on the underside of the arch to catch any loose brickwork. To finalise the arch repair process, we point these sections with fresh but similar looking mortar to leave the arch appear as if untouched.

Lintel Repair Method

Repairing Failed Concrete Lintels

Using power cutting tools, we cut slots through the concrete to a specified depth, vertically and horizontally. The tools feature vacuum attachments which suck up concrete powders as we cut to keep your home tidy and clean.

After cutting, we bond a single 6mm HelicalBar™ into each slot using GroutSet. For any crack that’s within 300mm of a corner, we pre-bend the HelicalBar™ to form a 90-degree elbow and extend the bar around the corner.

To finalise the lintel repair process, we point these sections with fresh but similar looking mortar to leave the lintels looking as if repairs never happened.

Repairing Failed Angle Iron Lintels In Cavity Walls

We begin this lintel repair method by removing old or even corroded steel and mortar from selected bed joints. We flush out any leftover debris with clean water, then place a single 6mm HelicalBar™ into each slot on both sides of the arch using GroutSet.

For any crack within 300mm of a corner, we pre-bend the HelicalBar™ to form a 90-degree elbow and extend the bar around the corner.

To finalise this lintel repair process, we point these sections with fresh but similar looking mortar. This leaves your lintels looking like they’ve never been touched.
