Trusted Underpinning Specialists Servicing Mitcham
Adelaide Underpinning Group is a trusted provider of underpinning services in Mitcham. Mitcham has a population of 1,832. Formerly known as Mitcham Village and established in the 1840s, the suburb carries a mix of older character homes on large blocks, post-war brick dwellings, and recent infill development within the City of Mitcham.
Mitcham is located at 34°59′13″S 138°37′30″E. Sitting at the foot of the Adelaide Hills escarpment, the soil profile transitions from flat clay plains to sloping, variable ground conditions closer to Fullarton Road and Brown Hill Creek. Older homes in this corridor are affected by reactive clay movement, poor subfloor drainage, and footing deterioration.
Adelaide Underpinning Group addresses wall cracking, floor movement, and footing failure across Mitcham’s established housing stock. Homes near Brown Hill Creek and along Fullarton Road show differential settlement linked to variable fill depth and ageing original footings. 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.
