Technical - GeoPoly™

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

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

1. What is GeoPoly?
  • GeoPoly is a highly advanced geo-polymer resin developed by Buildfix.
  • There are two variants; GR60 and GR90.
  • GR60 is a fast reacting resin, design specially to underpin and lift residential buildings.
  • GR90 is a slow reacting resin, and utilised for large void filling projects and civil applications, such as slab lifting.
  • GeoPoly is made in Australian from local and imported materials.
2. How does GeoPoly work?
  • GeoPoly is injected directly below subsided structures to seek-out voids and weakness in the foundation soils.
  • Within seconds, it expands many times it’s the original volume.
  • The force generated by expansion is more than enough to completely fill any voids and counter the compressional load from above.
3. How long does it take for GeoPoly to start working?
  • During most residential repairs, GeoPoly GR60 can set within 33 seconds (cream time), and takes 8 minutes to fully cure.
  • In civil applications, GeoPoly GR90 sets within 45 seconds (cream time), and takes 20 minutes to fully cure.
  • After curing, concrete driveways, floors and walkways can be used. This includes pedestrians and vehicles.
4. Can I stay home during repairs?
  • Yes, there might be some noise from drilling, but you should be able to go about your daily business.
  • For safety reasons, we recommend that children and animals are supervised and kept away from the work areas.
5. How far under the structure can GeoPoly be injected?
  • Up to 3 meters below ground if required.
  • Average injection depth is between 100mm and 1000mm.
6. Can GeoPoly re-level my house?
  • Yes, if conditions are suitable.
  • However, our first priority is to underpin the structure, and stop further subsidence.
  • A lift of 1 – 5mm demonstrates a successful outcome. After it has been underpinned, our technicians will then continue to lift the structure to the required level, or until further injection and lifting is not possible.
7. Will my wall cracks close?
  • In most cases, cracks will reduce in width, or close completely.
  • In some instances, cracks may not close.
8. How do you monitor the lift?
  • We utilise the latest laser levelling equipment to ensure millimetre accuracy when lifting structures.
9. How long do I wait until decorating?
  • After treatment, the structure will take several weeks to settle.
  • Structural repairs can begin soon after; however, cosmetic work should not start for at least four weeks, unless specified by Buildfix.
10. Can GeoPoly cause additional issues?
  • As the structure lifts and returns to normal, GeoPoly may cause issues such as; slight cracking, sticking doors and gaps on surfaces. Existing cracks that have been filled may reopen.
  • These issues are positive outcomes and demonstrate a structural lift, and that GeoPoly has countered the subsidence problem.
  • Although these issues may seem alarming, they are regarded as a normal part of the process when underpinning and lifting structures, and can be easily repaired.
11. Can GeoPoly stop clay from reacting?
  • Reactive clay is a natural phenomenon that can cause structures to heave (lift) and subside (sink) depending on the moisture content.
  • Under treated areas, GeoPoly can limit the effects of heave by reducing the permeability of clay.
  • Due to the unpredictable nature of reactive clay, and locations underneath, stand-alone underpinning solutions may not offer full support to a structure.
  • Additional remediation works, such as HelicalBar installation, and movement control joints in walls is always considered by Buildfix to ensure a permanent fix.
12. Can my building move after GeoPoly repairs?
  • Yes, all structures move as they’re exposed to a variety of natural forces.
  • Thermal expansion and contraction of building materials, wind pressure, and changes in ground conditions can all impact a structure.
  • Buildfix have developed many repair methods to mitigate natural structural movement.
13. Will I need to fix the cracks above ground too?
  • If your building has structural cracks, we always recommend fixing them as standard practice.
  • Standalone underpinning may not offer full support to a structure.
14. What will my warranty cover?
  • Our GeoPoly warranty covers all areas that have been detailed in the quote to repair subsidence for up to 10 years.
  • In the rare case your structure sinks again in the areas detailed, we will return to re-inject at no cost to you.
15. Is GeoPoly safe for the environment?
  • GeoPoly belongs to the polyurethane family, a widely used material found in many household items.
  • It is classed as a non-hazardous product.

Technical - HelicalBar™

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

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

1. What are HelicalBars?
  • HelicalBars are non-disruptive stainless steel bars design to strengthen cracked walls and failed masonry buildings.
  • HelicalBar comes in two different widths, 6mm for crack stitching, and 8mm for lateral wall ties. Lengths are cut onsite to suit individual job requirements.
2. How many years will HelicalBars last?
  • Our HelicalBars are made from grade 316 stainless steel.
  • They are manufactured to resist corrosion for up to 50 years, which meet Australian Standards.
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. Does the wall require rebuilding before HelicalBar is installed?
  • HelicalBar installation removes the need to knockdown and rebuild. Bricks and other masonry units, always stay in place.
  • This can save customers 1000’s of dollars.
5. Do HelicalBars have enough strength to reconnect my wall??
  • Yes, they are very strong. Much stronger than normal building materials, such as concrete.
  • Under tension (tensile stress), HelicalBar on average are 120 times stronger than unreinforced concrete, and 90 times stronger than bricks.
  • HelicalBar exceed all performance requirements set by Australian Standards for lateral load ties.
  • 6mm HelicalBars are 1200 MPa and 8mm HelicalBar are 1250 MPa.
  • When bars are coupled with grout and set in the wall, the tensile strength can be as much as 2000 MPa. That’s almost 200 times strong than brickwork.
6. Will there be dust or mess?
  • Dust and mess from structural repairs are inevitable. To combat this problem, Buildfix use the latest vacuum 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.
7. Should HelicalBars be installed before or after GeoPoly injections?
  • This will depend on the structural problem and location.
  • If subsidence has occurred, and structural wall cracks are evident, HelicalBar installation is often required to ensure a permanent fix.
8. Can I stay home during repairs?
  • Yes, there will be noise from cutting and drilling, but you should be able to go about your daily business.
  • For safety reasons, we recommend that children and animals are supervised and kept away from the work areas.
9. Should I remove anything out of the way?
  • Yes, all furniture and valuables should be removed from the repair area before our technicians arrive.
  • This will save time on the day, ensuring the job will be finished on schedule.
10. What will my warranty cover?
  • Our HelicalBar warranty covers areas that have been detailed in the quote to repair wall cracks for up to 10 years.
  • In the rare case, your structural problems return, in the areas detailed and repaired by us, we will return to repair at no cost to you.

Technical - DampBlock™

For general questions regarding rising damp repairs

For general questions regarding rising damp repairs

1. What is DampBlock?
  • DampBlock is our damp proofing injection fluid designed specifically to stop rising damp in masonry walls.
2. How does DampBlock work?
  • It blocks the tiny capillaries in walls to combat capillary action – the natural process that causes rising damp.
3. Can DampBlock stop lateral damp?
  • DampBlock is designed to repair naturally occurring rising damp, it’s not a solution for lateral damp.
  • Lateral damp is always caused by a fault externally with drainage or plumbing. In these cases, a plumber should be sought to fix the damp.
4. How many years will the DampBlock last?
  • DampBlock has been developed to resist rising damp in walls for at least 20 years.
5. Can you see evidence of the repair?
  • DampBlock is invisible after 24 hours.
6. Can salt cause problems after treatment?
  • After rising damp treatment, salts can crystalise near the surface as the wall dries, and expand on the surface, causing issues with plaster and mortar joints
  • Salts can increase moisture levels on the surface due to it’s hygroscopic nature, which can allow fungal growths to form, and render transfer moisture meters to be redundant.
7. Is DampBlock odourless?
  • While injecting DampBlock there will be a slight odour present. After it is set, you will not smell a thing.
8. How long will it take for my wall to dry?
  • The exact length of time will depend on wall thickness, porosity of the bricks, amount of moisture within the wall, and climate conditions.
  • Walls can take up to 1 year to dry.
