Structural Repair Solutions

Every structural repair we do — from wall cracks to underpinning — is non-invasive and most jobs done in a day or two.

Underpinning — GeoPoly™ resin injection lifting and stabilising a brick home foundation

Underpinning

Stop your foundation sinking. Underpinning lifts and stabilises the ground beneath your home — no digging, no mess, done in 1–2 days.

Wall crack repair — HelicalBar™ stainless steel reinforcement bonded into a brick wall

Wall Crack Repair

Fix structural cracks in your walls — permanently. Wall crack repair strengthens the masonry without knocking walls down or rebuilding.

Damp proofing — DampBlock™ silicone injection forming a new damp proof course in mortar

Damp Proofing

Stop rising damp in your home. Damp proofing blocks moisture rising through the mortar — permanent, non-invasive, no digging.

Floor pier repairs — GeoPoly™ resin stabilising sub-floor piers and levelling timber floors

Floor Pier Repairs

Stop your floors sinking and bouncing. Floor pier repairs lift and stabilise the ground beneath your floor piers — no floorboards removed.

Concrete relevelling — GeoPoly™ resin lifting a sunken concrete slab back to level

Concrete Relevelling

Lift sunken slabs back to level. Concrete relevelling raises driveways, paths, floors and pool surrounds from below — walk or drive on it the same day.

Remedial wall ties — HelicalBar™ stainless steel ties securing a leaning external brick wall

Remedial Wall Ties

Pull leaning and bowing walls back into line. Remedial wall ties permanently reconnect cavity walls — no rebuild required.

Salt damp repair — DampBlock™ injection stopping salt-laden moisture rising through a brick wall

Salt Damp Repair

Stop salt damp destroying your brickwork. Salt damp repair blocks the moisture that carries the salt at its source — permanent and non-invasive.

Stump lifting — GeoPoly™ resin raising and stabilising sub-floor stumps under a timber floor

Stump Lifting

An alternative to restumping. Stump lifting raises and stabilises the stumps beneath your home — no floorboards removed, no relocation.

Plaster wall repair — HelicalBar™ reinforcement behind the wall, then skim and paint-ready finish

Plaster Wall Repair

Fix cracked plaster permanently. Plaster wall repair strengthens the wall behind the plaster first — clean skim, paint-ready finish.

It matters when your home breaks. It matters to fix it right.

Fixing your home right doesn't mean digging holes or knocking down sections of floors and walls. It has to be right for you, right for the longevity of your home, and — importantly — right for your budget.

Structurally repairing the wall crack that keeps getting wider. Underpinning your home when it starts heading south. Blocking rising damp at the source before it takes over your life. That's exactly what Buildfix does.

For nearly 15 years, Buildfix has been delivering non-invasive structural repairs — saving homeowners the upheaval and rebuild costs of traditional methods. What used to take weeks now takes 1–2 days.

How does Buildfix do it all? Every part of the structural repair stays in-house. Buildfix is the licensed builder. Our structural engineers assess and oversee the job. Our technicians carry out the repair. Even the technology — like GeoPoly™ injection resin — is made in-house. One team, assessment to warranty.
