Trusted Underpinning Specialists Servicing Modbury

Adelaide Underpinning Group provides specialised underpinning services in Modbury. Modbury has a population of 5,593. A well-established north-eastern suburb within the City of Tea Tree Gully, Modbury was developed from the 1960s through to the 1980s and features brick veneer and double-brick family homes on generous blocks alongside more recent infill townhouses.

Modbury is located at 34°50′S 138°41′E. Sitting at the edge of the Adelaide foothills, the terrain rises and falls across rolling ground with clay-rich subsoils throughout. Homes along North East Road and Wright Road sit on ground that responds strongly to seasonal moisture change, causing slab heave, footing movement, and differential settlement.

Adelaide Underpinning Group addresses footing failure, floor unevenness, and wall cracking across Modbury’s established housing stock. Brick veneer homes near Reservoir Road and Smart Road show stepped cracking, sticking doors, and sloping floor lines. Adelaide Underpinning Group restores foundations to a stable, dependable condition that meets current building standards.

Our 6-Step Underpinning Process

Below are the steps in our underpinning process:

Step 1: Initial Site Assessment

Our builders inspect foundation conditions, floor levels, soil type, subfloor access, and visible structural movement. We identify the cause and determine the most appropriate repair method before any work is scoped.

Step 2: Detailed Quotation

We provide a fixed quote covering materials, labour, permits, and inspection stages. The full scope is outlined clearly so clients know exactly what is included before committing to the job.

Step 3: Permits and Approvals

Our team handles all council permits and building approvals on the client's behalf. Inspection points are confirmed with the relevant authority and work is scheduled around those requirements.

Step 4: Site Preparation

Temporary supports are installed where required and safe access is established. Surrounding landscaping, pathways, and internal finishes are protected throughout the preparation phase.

Step 5: Underpinning and Repairs

The approved method of mass concrete, screw piles, slab lifting, or structural repairs is carried out in controlled stages. Load distribution is maintained across the structure throughout the entire process.

Step 6: Final Inspection and Handover

Foundation levels are verified, compliance with building standards is confirmed, and the site is cleaned before handover. Permits, inspection certificates, and a full record of works are supplied to the client.
