The quality of work was outstanding

I recently had the pleasure of working with Mainmark for a driveway repair project in Kiama. Their team’s approach to lifting and repairing the sunken concrete driveway at one of our sites was nothing short of professional and efficient. The quality of work was outstanding, and their attention to detail was commendable. As a builder specialising in bespoke renovations, it’s crucial for me to collaborate with teams that maintain high standards, and Mainmark did just that. I highly recommend their services for their expertise and professionalism. Looking forward to our next project together!

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!

I saved $60K+ with Mainmark!
Exceptional!! I had a quote for $60k+ from one company to lift my slab because they said it was sinking. Sam from Mainmark turned up, took measurements and advised me that my slab was actually lifting because of water issue. Where the other mob wanted to lift my slab the measurements taken showed that there was no issue in that area but the lift was in fact on the other side of the house. Sam provided advice and didn’t take a cent from me. Thank you for your honesty you could have tried to rip me off like the other mob and left me in a worse position but you didn’t. Highly recommended!!

Causes of Driveway Concrete Cracks

The Underlying Reasons for Driveway Subsidence

Driveway concrete cracks commonly arise from a variety of factors. Environmental stress, such as extreme temperature fluctuations and moisture changes, can cause the concrete to expand and contract, leading to cracks. Subsidence, where the underlying soil shifts or settles, often results in uneven support and cracking.

Additionally, the natural aging of concrete, alongside wear and tear, contributes to its deterioration over time. Inadequate construction practices, including improper curing and poor-quality materials, can also predispose a driveway to cracking. Understanding these causes is crucial for effective and long-lasting repair solutions.

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.

Frequently Asked Questions

We’ve compiled answers to some of our customers’ most common questions.

However, we understand that your situation may be unique, and you might have specific questions not covered here.

If you’re worried about subsiding concrete, call Mainmark for an obligation free expert opinion.

Is it normal for concrete driveways to crack?

Yes, it is relatively normal for concrete driveways to develop cracks over time due to factors like environmental stress, ground movement, and natural aging of the material. Regular maintenance and timely repairs can help manage and minimise these cracks.

How do you know if concrete crack is serious?

A concrete driveway crack is considered serious if it’s wider than 0.3 mm, indicating potential structural concerns. Cracks that widen enough to create tripping hazards or allow water seepage should be addressed promptly.

Cracks wider than 3.2 mm in the driveway are particularly concerning and require attention. While small hairline cracks may not immediately signal a structural issue, larger, more noticeable cracks, especially those that change over time, should be professionally evaluated and repaired to maintain the driveway’s integrity and safety.

How much does concrete driveway repair cost?

The cost of concrete driveway repair varies widely depending on several factors, such as the extent of the damage, the repair method used, and the size of the driveway. For minor crack repairs using methods like sealing, costs can be relatively low. However, more extensive repairs involving resin injection technologies like Teretek® or complete driveway resurfacing can be more costly. On average, repair costs can range from a few hundred to several thousand dollars. It’s best to get a customised quote from a professional service like Mainmark for an accurate estimate based on your specific driveway’s condition.
