UNDERPINNING VS. RESIN INJECTION

The Truth About Protecting Your Home’s Foundation

Choose the Solution That Lasts
Underpinning: The Proven Way to Stabilize Your Home
Don’t risk your biggest investment on quick fixes.
Discover why underpinning remains the gold standard for long‑term foundation stability.

What Is Underpinning?

Underpinning is a structural engineering method that strengthens and stabilizes your home by extending the foundation down to stronger, more stable soil.

Why Homeowners Trust Underpinning

Reaches stable load‑bearing soil
Permanently strengthens the foundation
Engineered and certified to Australian standards
Suitable for all soil types, including reactive clay
Ideal for homes with significant or ongoing movement
Provides long‑term peace of mind

Underpinning doesn’t just lift your home — it rebuilds its strength from the ground up.

What Is Resin Injection?

Resin injection pumps expanding polyurethane resin into the ground to fill voids and lift sections of the slab. It is often marketed as a fast, low‑cost alternative — but it rarely addresses the real cause of subsidence.

Limitations of Resin Injection

Does not reach deep, stable soil layers
Does not strengthen the foundation
Can mask symptoms without fixing the cause
Resin can shift, shrink, or break down over time
Not suitable for major structural movement
Higher risk of future sinking

Resin Injection is a Temporary Lift and Not a structural repair. It is a BAND-AID Only.

Takeaway Note:

Why Underpinning Is the Best Investment

Fixes the cause, not the symptoms
Protects your property value
Engineered, certified, and guaranteed
Long‑term savings
Subsidence happens because the soil beneath your home can no longer support its weight.
Underpinning rebuilds the foundation on stable ground.
A properly underpinned home is far more attractive to buyers and insurers than one with resin‑filled soil.
Underpinning is carried out under strict engineering supervision, ensuring long‑term structural integrity.
A one‑time underpinning job prevents repeated repairs, cosmetic patching, and future structural damage.

Choose the Solution That Lasts a Lifetime

Resin injection may look like a quick fix — but underpinning is the only method that truly stabilizes your home for decades to come. Protect your home. Protect your investment. Choose underpinning.
