  • I just wanted to say the whole process of underpinning my house was conducted in a most pleasant and efficient manner from first inspection and quoting through to the work done. During the day of the work I was kept fully informed of progress and at the end of the day you would not know they had been! We are very pleased with the result.

  • We have a 2 storey house with solid brick walls outside and some brick/stud walls inside. Ground floor is concrete slab and upper floor timber. It sits on a sloping embankment which has subsided over the years, causing some cracks, but only on the outside walls facing the embankment. That is, the slab has tilted about 25 mm along the length of the house. Concrete pier underpinning was going to be very expensive and disruptive, so I canvassed 3 ground injection firms. One didn’t reply (after a number of calls), the other talked of a scary price. By chance I found Resinject who gave me a quote with a professional plan of injection points (about 24 in all, some with double tubes, and many over 2 metres deep.)

    The project was explained in detail, and we were consulted about contingencies in the event of unknown void pockets in the embankment. I was on site witnessing all the work, and the read-outs on the injection pumps. I only paid for the labour, travel and fuel once and was happy to pay for additional material as was necessary. They came to the site 3 times. The team, Glenn, Julio and Keyan (and later the boss Andy) were very friendly, explaining each step, and worked virtually non-stop. They even spent an hour each time to clean up. My house is very heavy, the site is difficult and I got a ten year guarantee. I certainly recommend this company.

  • Glenn and the guys were really wonderful! They are a tight, friendly team and just worked relentlessly through the day and just so diligent –  but also got on so well with one another. Lovely and respectful and kept me up to date the whole time – I will be recommending them to anyone that has had the same problems with their buildings.

  • As the crew stayed onsite in our B&B accommodation, we were able to observe them first-hand. We noted that they were very punctual, and worked very efficiently and tirelessly throughout the day. They were very conscious of workplace health and safety at all times and were very good at verbally communicating how the work was progressing throughout the day in relation to our budget and the amount of resin used. As we have very little understanding of the building industry, they were particularly patient when explaining to us about their work and any issues arising during the course of their work. They left the area very neat and clean after completion of the job.

    Irons,C&T – Thorneside, QLD

  • From initial consultation through to completion of my slab lift, the team @ Resinject were of a very professional manner and showed great care being in someone else’s home. The approach of each team member on the job whilst the lift was happening and setting up was second to none. Having been taken to the truck to explain how the process works, and being able to witness and have the works explained to me – made the whole process a lot clearer and very appreciative of what this resin can achieve with precise calculations and decision making.

    Thank you Resinject for completing the works and I will most certainly pass on your name to promote your services.
