FAQs
Frequently Asked Questions
UNDERPINNING VS. RESIN INJECTION
The Truth About Protecting Your Home’s Foundation
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, not a structural repair.

Why Underpinning Is the Best Investment
-

-
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.
