What Is Resin Injection?

Resin Injection is a modern ground improvement and re-levelling method that replaces the need for traditional underpinning or concrete replacement.

The process involves injecting a specialised engineered resin beneath a home’s foundations or concrete slabs. The resin expands, compacting weak soils, filling voids, and lifting the structure back to level, often within just a few hours.

At Mainmark, we use our proprietary Teretek® engineered resin, proven across thousands of residential and commercial projects worldwide and trusted by homeowners throughout Melbourne and Greater Victoria.

How much does resin injection cost?

Residential resin injection costs depend on property size and soil conditions, but most home repairs range from $4,000 to $15,000. Mainmark provides free, no-obligation quotes.

Is resin injection permanent?

Yes. Once the resin expands and hardens, it creates a durable, stable base that will not shrink or deteriorate over time.

How long does resin injection take?

Most residential jobs are completed within a few hours, allowing you to stay in your home during the process.

Is resin injection safe for my family and the environment?

Yes, Teretek® resin is inert, non-toxic, and environmentally safe once cured.

What’s the difference between resin injection and concrete underpinning?

Resin injection is cleaner, faster, more cost-effective and far less disruptive, without the need for excavation or structural digging.

How does resin injection work for foundation repair?

Resin injection works by placing a two-part expanding resin beneath your foundation. As it expands, it compacts weak soil, fills gaps, and lifts the structure to level. The process is monitored with laser precision to ensure accurate results.

Does resin injection fix cracked walls and uneven floors?

Yes. Once your home is stabilised and re-levelled with resin injection, many cracks close naturally, and uneven or sloping floors are brought back to level. Remaining cosmetic cracks can then be permanently repaired.

What problems does resin injection fix?

Resin injection repairs and stabilises:

subsidence
sinking floors
cracked walls
uneven slabs
voiding beneath foundations
sunken driveways and patios

It’s a versatile solution for most home settlement issues.

Does resin injection help prevent future subsidence?

Yes. By densifying and strengthening the ground beneath the foundation, resin injection helps prevent further movement and reduces future subsidence risks.
