Our Services

Remedial Building Services We Provide

Crack Stitching

Structural cracks in brick walls are stitched back together using Thor helical ties, restoring the wall's structural integrity across the crack.

Mortar Repointing

Deteriorated mortar joints are ground out and replaced with fresh sand-cement mix, restoring the brickwork and sealing the wall against water ingress.

Re-Rendering

Damaged render is removed, expanded mesh is pinned across the repair, and the wall is re-rendered and finished to match the surrounding surface.

Wall Reinforcement

Remedial wall ties and bed joint reinforcement are installed where masonry walls have separated, lost structural integrity, or started to lean.

What is Remedial Building?

Remedial building is the process of repairing the structural and cosmetic damage left behind by foundation movement, water damage, or general structural deterioration. It covers crack stitching, mortar repointing, masonry reinforcement, expanded mesh installation, re-rendering and finishing works.

At AllenCo Construction, remedial building is the second half of every underpinning job. Once the foundation has been stabilised with reinforced concrete bored piers, the structural cracks in your walls, the loose mortar joints, and the damaged render are repaired permanently. Because the foundation is stable, the repairs hold.

The remedial works are carried out by the same licensed builder who performed the underpinning. One team. One warranty. One point of accountability from the first crack inspection through to the final coat of paint.

I had a fantastic experience with Allenco. I own St Canice Catholic Church in Snowtown, which I purchased two years ago, and unfortunately the building required significant underpinning due to major cracks opening up in the brickwork. From start to finish, the team at Allenco were professional, knowledgeable, and extremely thorough. Underpinning a historic building is no small task, but they approached the job with care, precision, and clear communication throughout the entire process. Their workmanship and attention to detail gave me real confidence that the structure is now secure for the long term. I truly appreciate the quality of their work and would highly recommend Allenco to anyone needing structural or underpinning services. A very professional outfit and well deserving of 5 stars.

Cody was very thorough and careful to explain everything during his initial visit to quote for underpinning at our house. When his workmen arrived to begin on the first day I was impressed that they all took time to introduce themselves to me and answer any questions. The team varied across the time of the works, but they always kept us updated on what was happening. They were neat and tidy and made sure everything was tidy and safe at the end of the day. They consulted with us and took care with our gardens and lawns. Cam, Liam, Kyle, Mark, Jersey, Leo and the others were a delight to have doing the work and I would highly recommend them.

We Fix the Cause, Not Just the Symptom

There’s no point patching a cracked wall if the foundation underneath it is still moving. AllenCo Construction, every remedial repairs project begins with diagnosis, so the repair holds long term. We run 3 checks before any repair work starts.

CCTV Drainage Inspection

A licensed plumber runs a camera through your drainage to rule out cracked drains, sewer leaks, or stormwater faults as the cause of the foundation movement.

Engineer's Assessment

A structural engineer assesses the cause and severity of the movement, and confirms whether the foundation needs underpinning before the remedial works begin.

Underpinning Where Needed

Where foundation movement is the cause, the home is underpinned and stabilised first. Only once the foundation is stable do the remedial repairs begin.

If your walls are cracking and you’re not sure whether you need underpinning or just a wall repair, see our wall crack repair page for the signs to look for.

FAQs

Remedial Building FAQs

Crack stitching is a structural repair method where helical ties are installed horizontally across a crack in a brick wall to bind the masonry back together. Thor helical ties are grouted into the mortar joints and covered with expanded mesh and render. The result is a wall that’s structurally tied back together across the crack.

You need underpinning before remedial works if the cause of the cracking is ongoing foundation movement. Repairing cracks while the foundation is still moving means the cracks will reopen. AllenCo inspects the cause of the damage first, performs the underpinning if needed, and then completes the remedial works once the foundation is stable.

The main difference between a remedial builder and a regular builder is that a remedial builder specialises in repairing and restoring existing structures, whereas a regular builder focuses on new construction. Remedial builders are trained in structural repair methods like crack stitching, underpinning, and masonry reinforcement.

All remedial building work is backed by our 10-year guarantee. Because we stabilise the foundation before completing the repairs, the cracks stay closed and the work holds. We’re a licensed builder with $10M public liability cover.
