Pathway Technologies | Stabilizer Solutions

Aggregates such as decomposed granite, crushed granite, limestone, or other types of crushed stone are considered “soils.” These aggregates contain the soil particles sand, silt and clay, along with gravel or rock particles. Soil particles are like the DNA of the pathway. They decide how your pathway will perform.

High Performance Bedding | HPB | Mississauga | Oakville

2021-11-24 · HPB (High Performance Bedding) is a crushed, washed limestone that is about 1/4″ in size. This product is a self-compacting base material that can be used as a replacement for crushed gravel and screening in patios and walkways. HPB is particulary good for areas with poor drainage as it allows for water to pass through it back into the ground.
