Our Expertise
Building on Strong Ground
Every great structure begins with a solid foundation. Our foundation and earthworks services cover the full spectrum of ground engineering — from soil assessment and footing design through to deep excavation support and retaining wall solutions.
We specialise in advanced slab systems, excavation support, and retaining structures, ensuring solid, long-lasting foundations for any project. Our engineering team assesses site-specific conditions and delivers designs optimised for safety, durability, and cost-efficiency.
- Soil classification and geotechnical assessment
- Reactive soil management for all site classes
- Full compliance with AS 2870 and NCC requirements

Australian Soil Classification Guide
Understanding your site's soil classification under AS 2870 is the first step to a properly engineered foundation. Each soil class determines the type of footing system required.
Stable, non-reactive soils with minimal ground movement. Typically sand, gravel, or rock — ideal for standard strip or pad footings with minimal depth requirements.
Mild seasonal moisture variation causing slight ground movement (0–20mm). Common in many Australian suburbs — standard waffle pod or stiffened raft slabs are usually sufficient.
Moderate ground movement (20–40mm) due to seasonal moisture changes. Requires engineered slab design with increased stiffening beams and deeper edge beams.
Significant ground movement (40–60mm). Demands robust slab design with deep beams, additional reinforcement, and careful moisture management strategies.
Extreme ground movement (60–75mm). Requires heavily engineered foundation systems — often pier-and-beam or deep bored piles to reach stable bearing strata.
Sites with fill, soft clays, landslip risk, mine subsidence, or other abnormal conditions. Requires site-specific investigation and bespoke foundation engineering solutions.
How We Work
Our process.
A structured, transparent approach from site investigation through to construction certification.
Site Investigation
Geotechnical assessment and soil classification to determine site conditions, bearing capacity, and reactivity — the foundation of every design.
Design & Analysis
Structural modelling of footing systems, slab designs, or retaining structures using industry-standard software and Australian Standards.
Documentation
Complete engineering drawings, calculations, and specifications — ready for council submission and builder construction.
Construction Support
On-site inspections, reinforcement checks, and certification to ensure the built foundation matches the engineered design.
AS 2870 Compliant
All footing and slab designs comply with AS 2870 residential slabs and footings standard, plus AS 3600 for concrete structures.
Council-Ready Docs
Complete engineering calculations, construction drawings, and specifications ready for council submission and builder use.
RPE Engineers
All designs prepared and certified by Registered Professional Engineers with extensive foundation engineering experience.
Every Structure Starts with the Ground Beneath It
