Looking for expert underpinning in Melbourne? Tactics Reblocking and Underpinning specialises in foundation stabilisation and concrete slab repair for modern homes across Melbourne. When slab foundations sink, crack, or shift due to soil movement, we restore structural integrity using proven underpinning methods — all backed by a written 15-year guarantee and supervised by a Registered Building Practitioner (Licence DB-L 54524).
What Is Underpinning — and How Does It Differ from Reblocking/Restumping?
The terms are frequently confused, but they apply to completely different foundation types:
- Reblocking / Restumping: For raised timber-framed homes sitting on timber stumps. Involves replacing wood with concrete stumps.
- Underpinning: For homes built on concrete slabs (modern brick-veneer construction). Involves stabilising, lifting, or reinforcing the existing slab foundation.
If your home has a flat concrete floor (no subfloor space), you need underpinning — not restumping. Unsure which applies to you? Call 0455 888 899 and we'll advise you honestly at no charge.

Underpinning Methods We Use in Melbourne
We select the most effective stabilisation technique based on your soil type, access, and structural requirements:
We assess your property and recommend the most cost-effective, structurally sound method. No single approach fits every Melbourne foundation.
Our Melbourne Underpinning Process — Step by Step
We visit your Melbourne property, assess slab movement, identify soil issues, and provide a free written quote — no obligation, no pressure.
We evaluate soil classification, moisture patterns, and load-bearing requirements to select the optimal underpinning method per AS 2870 standards.
We clear work zones, protect landscaping, and set up temporary supports if required. Most Melbourne homes allow perimeter access without major disruption.
Piers or resin are installed to transfer foundation loads to stable soil strata. We monitor lift levels in real-time to ensure precise re-levelling.
Using hydraulic jacking, we carefully lift settled sections back to level. We verify door/window operation, crack alignment, and overall structural stability.
Comprehensive check before sign-off. All work performed by Registered Building Practitioner (Licence DB-L 54524) with written 15-year guarantee.

Frequently Asked Questions — Underpinning Melbourne
Underpinning is for homes built on concrete slabs (typically modern brick-veneer construction) where the slab has cracked, sunk, or become uneven. Reblocking/restumping is for raised timber-framed homes on timber stumps. If you're unsure which applies to your property, call us for a free assessment.
Underpinning costs in Melbourne vary based on the extent of slab settlement, soil conditions, access, and the method used (mass concrete, screw piers, or polyurethane injection). We provide free, written quotes with no obligation. Call 0455 888 899 to arrange an on-site assessment.
Common causes include Melbourne's reactive clay soils (expansion/contraction), poor initial soil compaction (common in newer Western/South-Eastern estates), leaking plumbing washing away subsoil, tree root moisture extraction, and coastal subsidence in bayside areas.
Most underpinning projects in Melbourne take between 3 and 10 days, depending on the size of the affected area, access constraints, and the stabilisation method chosen. We provide a detailed timeline during your free quote.
Modern underpinning methods are designed to minimise disruption. We work from the perimeter or through small access points. Most homeowners can remain in their property during the process, though we may advise temporary relocation if extensive structural jacking is required.
