For general questions regarding subsidence, sinking floor pier and sunken concrete repairs

1. How many years will GeoPoly last?
  • To ensure repairs stand the test of time, GeoPoly has been engineered to retain its closed-cell density and last for over 50 years.
2. Are GeoPoly repairs guaranteed?
  • Yes, all GeoPoly repairs come with an industry-leading 10-year warranty.
  • Our comprehensive warranties cover both labour and materials. In the rare case your home moves again, we will be back to underpin your foundation at no additional cost.
3. Does my home require wall crack repair after underpinning work?
  • If your home has noticeable cracks, repairs above ground could be essential to return the structural integrity.
  • Uniquely, Buildfix can repair foundations below ground, structures above ground and cosmetic problems too – saving customers the hassle of organising multiple trades, and the high costs this involves.
4. How far under the structure can GeoPoly be injected?
  • Up to 5 meters below ground level if required. Average injection depth is between 500mm and 1500mm.
5. Can GeoPoly level my house?
  • Yes, if conditions are suitable. However, our priority is to underpin the structure by consolidating foundation soils and increasing the load-bearing capacity.
  • A lift of 1 – 5mm demonstrates a successful outcome. After it has been underpinned, our technicians will then continue to lift the structure until the required level is reached, or until further injection is not possible.
6. How do you monitor the amount of lift?
  • We use the latest laser levelling equipment to ensure millimetre accuracy.
7. How long do I have to wait until carrying out cosmetic repairs?
  • After treatment, the structure will take several weeks to settle.
  • Structural works can begin soon after; however, cosmetic work should not start for at least four weeks unless specified by Buildfix.
8. Can GeoPoly injections cause additional issues?
  • As the structure lifts and returns to normal, GeoPoly may cause issues such as; slight cracking, sticking doors and windows and gaps on surfaces.
  • These issues are generally regarded as a positive outcome as it shows the GeoPoly has countered the subsidence problem.
  • Although these issues may seem alarming, they are regarded as a normal part of the process when underpinning structures and can be easily repaired.
9. Can GeoPoly stop clay reacting?
  • Reactive clay is a natural phenomenon that can cause structures to heave (lift) and subside (sink) within a cyclic time period.
  • GeoPoly works to significantly reduce the effect of reactive clay by compacting aerated and damaged soil under footings.
  • Due to the unpredictable nature of reactive clay, stand-alone underpinning solutions may not offer full support to a structure in the event of heave. Additional remediation works, such as HelicalBar installation, and articulation joints above ground is always considered by Buildfix to ensure a permanent fix.
10. How long does it take for GeoPoly to take effect?
  • During foundation repairs, GeoPoly sets 95% within two minutes and takes 24 hours to cure.
11. Is GeoPoly safe for the environment?
  • Yes, it is environmentally friendly. GeoPoly belongs to the polyurethane family of chemicals – which are classed as non-hazardous.


For general questions regarding wall crack, arch lintel failure and leaning wall repairs

1. How many years will the HelicalBar last?
  • Our HelicalBars are made from 316 marine grade stainless steel, designed to resist optimal lateral loads and lasts without corrosion for up to 50 years, which meet the Australian standard AS 3700 masonry structure requirements.
2. Are HelicalBar repairs guaranteed?
  • Yes, all repairs come with an industry-leading 10-year warranty.
  • Our comprehensive warranties cover both labour and materials. In the rare case, structural cracks reappear, we will be back to fix at no additional cost.
3. Can you see evidence of the repair?
  • Our HelicalBar solutions are non-disruptive.
  • HelicalBars are installed deep within walls and cannot be seen from the surface.
  • Repairs are covered over with our mortar matching system to blend in with the original. Some colour variations may occur.
4. Will there be dust or mess?
  • Dust and mess from structural repairs are inevitable. To combat this problem, Buildfix only use the latest equipment to reduce dust to a minimum and all work areas are sheeted and covered. Our technicians pride themselves on their cleanliness
  • We’ll treat your home as if it’s ours.
5. Should HelicalBars be installed at the same time as GeoPoly injections?
  • This will depend on the cause of the problem. If subsidence has occurred and wall cracks are evident, HelicalBar installation is often required to ensure a permanent fix.


For general questions regarding rising damp repairs

1. How many years will the DampBlock last?
  • DampBlock has been designed to resist rising damp in walls for at least 20 years.
2. Can you see evidence of the repair?
  • DampBlock is invisible after 24 hours.
3. Does the plaster need to be removed before or after treatment?
  • Removing plaster from walls is rarely required and only recommend if it is loose.
4. Can salt cause problems after treatment?
  • As walls dry overtime, salts can crystallise and cause issues with plaster.
  • However, these problems are rare and very costly, and therefore should only be rectified as and when.
