Concrete Resin Injection

Resin Injection

Advanced Concrete Resin Injection Solution

Concrete resin injection is a highly effective and efficient technique for addressing subsidence in structures. This innovative technique involves injecting a specially formulated resin into cracks or voids within the concrete. As the injected material solidifies, it creates a strong bond between the affected sections, thereby restoring the structural integrity and strength of the concrete.

Ideal for various applications, from residential to commercial structures and infrastructure, concrete resin injection is a minimally invasive solution.

  • 50 year product warranty
  • 30+ years experience in Australia
  • Non-invasive and surgical method
  • Modern underpinning alternative
  • Cost-effective compared to traditional methods

Highly Recommended!

Highly recommended! We noticed a crack appear in one of the walls in our house and wanted to have our concrete slab checked to see if it was sinking before it got worse. We called Mainmark Ground Engineering and they sent out Connor and Philip to do an assessment and quote. We were a bit nervous about what they would say because we had no idea about what could be wrong or what it could cost to fix. They were super friendly and professional and did a detailed level check of the entire floor with some high tech looking devices and came to the conclusion it was nothing to worry about, it was just sessional movements from the weather getting hotter and the house expanding a little. They also gave us advice on what to look out for with concrete slabs in the future. We really appreciate the effort and attention to detail they showed. It’s refreshing to deal with people like this, I’d recommend these guys to anyone!

Communications with head office (lovely Sandy) were faultless!

Martin came out to inspect my property and from the get-go – I knew I would end up choosing Mainmark. Martin took the time to review the property and also spent time discussing the issues with me. A clear scope of work & a quote came quickly. Once I accepted the quote, communications with head office (lovely Sandy) were faultless! I was considered in all plans. On the day of the job, 3 top blokes (Kevin & crew) turned up on time and were not only focused, but super friendly. They left the work area clean & tidy. The end result – incredible! My driveway and concrete pathway is no longer sinking with unsightly gaps. I’m thrilled! Within a day of final payment, I was given my 50 year warranty certificate. Thanks Mainmark! Can’t recommend you guys enough!

The best solution to fix this problem was obviously resin injection

It was in March 2023 that a subsidence issue was found in my property in Ballarat as part of a building inspection report. The best solution to fix this problem was obviously resin injection. I got a number of quotes and consulted a number of experts to finally appoint the best ground engineering service for this purpose. Sam Hassan from Mainmark was able to gain my trust. He is very good at supporting the customer throughout the entire work process from the initial property inspection, to contract and price negotiations and finally the project completion. His careful assessment of the issue did make us organizing a drain inspection and helped us with discovering few drainage issues at the property as well which got addressed and fixed afterwards. Mainmark were really efficient and completed the Teretek injection in less than 4 hours. Polyurethane resin injection is an expensive service but when it becomes a necessity, it’d be better to be applied sooner than later and surely I highly recommend Mainmark Australia for this purpose.

Understanding the Causes of Concrete Cracks

The Underlying Reasons for Concrete Subsidence

Concrete, despite its robustness, is susceptible to cracking, which can compromise the structural integrity and aesthetics of buildings and infrastructure. Understanding the root causes of these cracks is crucial in selecting the right repair method, such as Teretek® for concrete injection.

Moreover, the impact varies depending on the type of ground involved. When the ground undergoes changes, building subsidence becomes a prevalent concern. In such cases, foundations or footings lose their support and sink due to the weakened ground.

Soil Types

Moisture levels in the soil affect reactive clays as they expand and contract.

Oversaturated clays lose their strength resulting in footing subsidence. In loosely packed soils, such as sand and silt, the fine particales in the soil can wash away causing the footing to settle.

Tree Roots

Neighbouring trees and shrubs absorb water using their roots causing movement in the soil as it soaks up moisture in the ground.

Footing Systems

Poor foundation design or inadequate compaction of soil during construction results in movement of the structure as it settles.

Excess Water

Burst or cracked water pipes including blocked sewage and rain gutters  can oversaturate clay soils or wash fine particles from sand and silt soils and cause footings to subside.

Extreme or Seasonal Weather

Natural disasters such as flooding, drought and earthquakes affect soil moisture levels in particular clay resulting in excessive foundation movement.

Renovation or Construction

Vibration caused by nearby construction activity such as drilling or piling, or heavy road traffic causes soil particles to shift and settle, resulting in ground subsidence.

What is concrete injection?

Concrete injection, often employed by Mainmark, involves injecting a specially formulated resin or grout into cracks or voids within subsided concrete structures. This resin injection processs strengthens and re-levels the compromised areas, restoring the structural integrity of the concrete. Mainmark’s unique product, Teretek®, is a notable example, offering a non-invasive, efficient solution for sinking concrete repair.

How long does concrete injection last?

The longevity of concrete injection repairs, especially when using Mainmark’s Teretek® technology, is significant. These repairs are designed to be durable and long-lasting. The exact lifespan can vary based on the environment and the specific conditions of the site, but they typically offer a long-term solution, often lasting several decades.

How much does concrete injection cost?

The cost of concrete injection varies depending on several factors, such as the extent of the damage, accessibility of the crack, the type of resin used, and the size of the project. Mainmark provides customised solutions, and costs are typically calculated after a thorough assessment of the specific needs of each project. Generally, it is a cost-effective alternative to more extensive repair methods.
