Recycled on-site foundations, civil and earthworks slash construction costs


[Earthmoving Equipment Magazine, October 2018]

On-site crushing and recycling of native materials is a win-win for cost cutting and the environment.

The latest in mobile crushing technology is being used as part of an efficient, innovative and environmentally friendly process that has demonstrated significant
cost savings for residential building, commercial structures and wide applications for infrastructure engineering.
An MB C50 crusher bucket fitted to an 8 tonne Kubota hydraulic excavator has been deployed on a steep and challenging residential building site to crush demolition spoil for recycling into by a revolutionary recycling process.
The MB Crusher processed tiles, bricks, mortar and foundation concrete that was recycled in-situ on a steep double block in Sylvania. The site presented challenges in terms of gradient and need for stabilisation. The result is massive and super-stable foundations on which two new homes are being built. Soilstone™ technology uses mechanical and natural chemical processes to treat native spoil to produce the properties of rock that can be formed into a structure. The process has been tested, evaluated and approved by the New South Wales building regulator.



Instead of building foundations from purchased concrete, the natural site material is crushed together with additive chemicals that recycle the spoil into an extremely durable and progressively hardening rocklike mass.
A major benefit of the site drainage design is the ability to form multiple drainage lines while retaining structural mass and stability.
The material is moisture impervious and allows you to use it to form drainage and
other structures in a way that would be difficult or more expensive than if using poured concrete.
The Soilstone process has been used successfully for mitigation of soil erosion, improved bearing capacity or subgrade reaction, improved resistance to water permeability, improved resistance to ground movement and vibration forces. The environmentally sustainable recycled material is not prone to corrosion like steel.


Alternative to unwanted or excess soil material, demolished concrete or brick material; materials can now be engineered to form mass engineered soil structure for particular use and function on site.
