Recovered stone
Stone and coarse aggregate recovered from hydrovac slurry, washed and screened at our Toronto facility. It's the first material to come out of the process.

What it is
Hydrovac slurry from the GTA carries a lot of stone: gravel, cobbles and crushed material from the same ground that pits and quarries work. It arrives suspended in water and leaves the first screening stage as a washed coarse aggregate, separated before the sand and fines.

How it's produced
Coarse screening
The load is tipped into the receiving hopper and runs across the first screens, which lift out stone and coarse gravel while everything finer passes through.
Washing
Retained stone is washed on the screen so silt and clay are carried into the water stream instead of coating the aggregate.
Stockpiling
The stacker conveyor builds a dedicated stone stockpile beside the receiving bays, where it drains to a handleable state.
Typical applications
Depending on project requirements and applicable specifications, recovered stone can be considered for:
- Construction backfill
- General and structural fill
- Sub-base and base preparation under slabs, pads and yards
- Concrete and mortar production
- Drainage layers
- Site access and temporary roads
Quality and documentation
Stone is supplied as a washed, screened recovered aggregate. Gradation and other properties vary with the source ground, so confirm the material against your project specification before ordering.
Our approval sets conditions on the sampling and analysis of recovered material. We keep the technical detail off the website and share it directly with buyers.

Common questions
Is recovered stone the same as quarried aggregate?
It's the same kind of material, gravel and rock that was already in the ground, recovered and washed rather than newly quarried. Its gradation depends on the source sites, so it's supplied as a recovered product and matched to suitable applications.
Can it go under a slab or pavement?
Recovered stone is commonly used in base and sub-base layers. Whether it meets a specific base specification depends on the project and the material's current documentation, so ask us for it.
