Ground stabilisation solution involving bulk fill modification and subbase stabilisation to improve material usability, enhance strength and support construction access.

6 weeks July 2025

Project Overview

This project involved bulk fill modification and subbase stabilisation to improve the engineering performance of site materials and enable their reuse within a commercial development scheme.

Engineering Approach

The works focused on reducing moisture content in unsuitable materials and stabilising soils using hydraulic binders, transforming them into a durable and load-bearing construction layer.

Why It Mattered

By improving existing materials rather than replacing them, the project achieved a more efficient, economical and sustainable earthworks solution while ensuring long-term performance.

Project Highlights

Category Ground Stabilisation
Application Earthworks / Subbase Stabilisation
Sector Commercial Development
Benefit Improved material usability and long-term durability

The Challenge

Cut and Fill Earthworks – 20,000m3
Bulk Fill Treatment of placed material to achieve >5.0% CBR (50Mpa) – 15,000m3
Capping and Subbase Replacement Stabilisation to achieve >30% CBR (150Mpa) – 22,000m2

The Solution

Moisture conditioning of unsuitable materials to reduce water content and enable reuse as engineered fill.
Mixing in hydraulic binders to alter soil properties and improve strength and durability.
Controlled stabilisation process to produce a consistent, long-term structural layer suitable for construction loading.
