Underpinning Sydney Inner West
Understanding the ground beneath your home is the first step to a lasting, compliant repair. We assess how local soil and heritage fabric affect foundations and building movement. That gives you a clear plan that protects structure and value.
Why local ground conditions and heritage fabrics matter
Inner West soils vary street to street. Soil compaction, moisture change and nearby excavation drive subsidence and cracks near openings.
Heritage brickwork and lime mortar need gentle staging and methods that avoid damage. Terraces share party walls, so we plan load paths to protect adjoining property.
Tailored solutions for terraces, federation homes and modern builds
We assess soil conditions, drainage and trees to target root causes. Then we choose techniques that match access, fabric and your needs.
- Resin injection improves ground with minimal interior disruption.
- Screw piles bridge weak ground to deeper bearing layers.
- Traditional underpins transfer load where excavation is possible.
We document foundations and ground data and provide tailored engineering documentation to support approvals and warranties. That reassures homeowners and investors alike.
Clear signs your foundations need attention
Look for early symptoms around doors, windows and floor lines to spot structural movement.
Cracks, sticking doors and uneven floors
New or widening cracks in plaster and brickwork often mean movement under the building. Cracks near openings are especially telling.
Doors and windows that stick or jam usually show frame distortion from settlement. Uneven floors or sloping rooms point to localised subsidence or failing timber support.
Gaps, sinking corners and visible movement
Gaps at skirting boards and benchtops reveal differential settlement. Sinking corners and stepped brick cracks indicate load path changes.
- Plaster ripples and stepped bricks may mean load redistribution.
- Moisture swings in reactive clay can speed up damage.
- Early assessment limits cost and disruption later.
| Symptom | Likely cause | Immediate action |
|---|---|---|
| New cracks near doors | Foundation movement or differential settlement | Send photos for quick review and book assessment |
| Sticking doors or windows | Frame distortion from settlement | Document timing and call for inspection |
| Uneven floors / sinking corners | Localised subsidence or support failure | Arrange early structural diagnosis |
| Gaps at skirtings | Differential settlement | Limit heavy loads and get a site check |
We speak calmly and clearly about symptoms. If you suspect foundation issues, send photos for a free, no‑obligation assessment. We confirm the cause and propose safe, compliant repairs that protect your home and property.
Our core services for stability and structural integrity
We deliver a clear set of services that target root causes and limit disruption. Our work pairs engineering oversight with certified methods so you get lasting, council‑ready outcomes.
Concrete underpins and screw piles for deeper bearing strata
Concrete underpinning transfers load to stronger layers below your foundation. Screw piles extend footings to verified, competent strata with precise installation and testing.
Resin injection for ground improvement and house re‑levelling
Resin injection strengthens weak ground and can re‑level a home with small access points and fast cure times. It often reduces program time and interior disruption.
Crack repairs, subfloor ventilation and retaining wall support
We stitch masonry, reinstate finishes and upgrade subfloor ventilation to manage moisture and timber health. We also stabilise retaining walls where soil pressure affects structures.
Engineering reports and council‑ready documentation
- Independent structural reports, drawings and certifications to support approvals.
- Solutions focused on permanence, not quick fixes.
- We scope work fairly and do not upsell—just the right repairs for your property.
Methods and techniques explained: choosing the right solution for your home
Selecting techniques is about matching site constraints to safety and long‑term performance. We start with a simple diagnosis of ground and soil so you know which method suits your property.
Traditional mass concrete underpinning
This method uses staged excavation and concrete pours to transfer load to deeper strata. It suits accessible areas with predictable soils.
Curing takes several days before reloading the foundations, and staged work controls movement and safety.
Resin injection
Resin uses tiny keyholes. It expands in the ground and cures quickly—often in about 30 minutes—so you can use the building during works.
Real‑time lift monitoring limits movement under sensitive fabric and reduces disruption and program time.
Screw piles
Screw piles extend footings to competent layers with minimal vibration. Installation is measured by shaft length and torque to meet design loads.
Combining methods for complex sites
Where reactive clays, trees or adjacent structures complicate works, we combine techniques to protect services and neighbours. We select the safest, most efficient solution for your home.
| Method | Access | Disruption | Time to strength |
|---|---|---|---|
| Mass concrete | Good access required | Higher (excavation) | Days (curing) |
| Resin injection | Small access holes | Low | Minutes (rapid cure) |
| Screw piles | Compact access | Low‑medium (installation) | Immediate measured capacity |
Costs, timeframes and disruption: what to expect
We provide transparent expectations on budget, program and disruption. That helps you plan and keeps stress low when arranging a repair to your foundation or house.
Typical cost ranges by method
Shallow traditional concrete underpins typically range from $1,000 to $4,500 per underpin depending on depth and access. Resin injection is usually quoted per linear metre and often falls between $1,100 and $1,400 per metre.
Program duration
Resin work can be completed in a single day with about 30 minutes cure per injection stage. Traditional underpins can take from a few days to several weeks, based on depth, shoring and site access.
Site access, gardens and hardscape
We plan around driveways, decks and gardens to reduce restoration needs. Limited access may increase handling time and reinstatement costs.
Fixed-price quotes and honest assessments
We provide fixed-price quotes that include reinstatement and disposal allowances. We outline risks and contingencies up front and do not upsell unnecessary works.
| Type | Indicative cost | Typical time |
|---|---|---|
| Concrete underpin | $1,000–$4,500 per underpin | Days–weeks |
| Resin injection | $1,100–$1,400 per linear metre | Same day |
| Screw piles | Varies by depth and load | Short program, measured installation |
We start by outlining costs by method and site complexity. That way you receive a clear quote and realistic time estimate before any work begins.
