Get an indicative estimate for your foundation stabilisation project
Estimate the cost of stabilising your foundation
Use our estimator to calculate an indicative cost range based on your property's foundation type, movement severity and project scope. Every Rectify project is engineered to suit the structure and ground conditions, so your final quotation is confirmed after a professional assessment.
Before You Estimate
- Built using typical Rectify project data
- Helps you understand likely investment before requesting a quotation
- Engineered solutions tailored to your property's conditions
- Final pricing confirmed after professional site assessment
Project Cost Estimator
Estimated range (ex GST)
This is an order-of-cost guide only. Final pricing depends on site conditions, required lift, resin volume and engineering design.
Typical Investment by Solution
Explore the typical investment ranges for Rectify's most common residential structural stabilisation solutions. These figures are indicative only and will vary depending on the size of the project, site conditions and engineering requirements.
Foundation Stabilisation
$600–$1,200 per linear metre

- Foundation movement
- Structural re-levelling
Best for: Homes experiencing cracks, sinking foundations or uneven floors.
Slab Re-levelling & Void Filling
$150–$320 per m²
Typical applications
- Void filling beneath slabs
- Sunken concrete slabs
- Pavements and hardstands
- Localised settlement correction
Best for: Restoring support beneath settled concrete without replacement.
Engineering & Assessment
$750–$1,400 per assessment
May include
- Site assessment
- Engineering review
- Structural recommendations
- Scope of works
Best for: Confirming the most appropriate remediation solution before works commence.

Why are these shown as ranges?
Every home is different. Foundation type, soil conditions, structural movement, site access and engineering requirements all influence the final project cost. Our estimator and assessment provide a more accurate indication based on your property's specific conditions.
Cost Influence:
- Foundation size and depth
- Severity of settlement
- Ground conditions
- Access around the property
- Required lift and stabilisation
- Engineering and council requirements where applicable
What's included:
- Engineered treatment design
- Precision resin injection
- Specialist equipment
- Qualified technicians
- Quality assurance throughout the works
Additional engineering, permits or structural repairs may be quoted separately where required.
Typical project examples
Every home is different, but these examples provide a realistic indication of common Rectify projects.
Minor Foundation Movement
- 8 lm Strip Footing
- Suitable for homes with minor cracking and localised settlement.
$7,500–$12,500*
Slab Settlement
- 50 m² Concrete Slab
- Ideal where voids beneath the slab have caused uneven settlement.
$7,500–$16,000*
Moderate Foundation Movement
- 18 lm Waffle Slab Edge Beams
- For homes requiring foundation stabilisation with moderate structural movement.
$13,000–$27,000*
*These examples are indicative only. Actual project costs vary depending on site conditions, access, engineering requirements and the extent of structural movement. Final pricing is confirmed following a professional assessment.
Frequently Asked Questions
Is this a fixed quotation?
The estimator provides an indicative project range. Your final quotation is prepared following a professional assessment.
Why can similar homes cost different amounts?
Every property has different soil conditions, foundation designs, access constraints and movement characteristics.
What happens after I submit my details?
One of our specialists reviews your information and contacts you to arrange the next steps.
Can most homes be stabilised without rebuilding?
In many cases, yes. Rectify's engineered chemical underpinning solutions stabilise foundations with minimal disruption compared with traditional underpinning methods.
How accurate is the estimator?
The estimator uses typical Rectify project data to provide an informed guide. Final pricing is confirmed following assessment.
How long do most projects take?
Most residential stabilisation projects are completed within a few days, depending on the size and complexity of the works.
