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.

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.
2021-10-28 · These two materials (limestone and shale) were extracted in the form of large blocks. The latter are crushed using a hammer for large diameters and a jaw crusher for small diameters. The grains thus obtained are of irregular shape. The samples were made in such a way that each sample consists of a single grain shape.
High Performance Bedding (HBD) This material is an angular, washed limestone that is free draining and deters soil migration. It is an alternative to screenings as a base material that does not need compaction; however it must be used in an enclosed space.
