Trusted Underpinning Specialists Servicing Mawson Lakes
Adelaide Underpinning Group is a trusted provider of underpinning services in Mawson Lakes. Mawson Lakes has a population of 13,794. Developed from the late 1990s on former wetlands known as The Levels, the suburb features contemporary family homes, townhouses, apartments, and commercial buildings across a master-planned grid layout.
Mawson Lakes is located at 34°48′50″S 138°36′43″E. Built on low-lying land with a high water table and expansive clay soils, many properties are susceptible to slab heave, subsidence, and seasonal soil movement. Streets around Mawson Lakes Boulevard and Garden Terrace sit on formerly wetland ground, increasing foundation risk beneath slab-on-ground construction throughout the estate.
Adelaide Underpinning Group addresses slab movement, footing settlement, and floor unevenness across Mawson Lakes’ newer housing stock. Properties near The Promenade and Main Street show differential settlement tied to variable fill compaction and reactive subsoil conditions. 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.
