The soil is the topmost layer of the earth's crust mainly composed of organic minerals and rock particles that support life. A soil profile is a vertical cross-section of the soil, made of layers running parallel to the surface. These layers are known as soil horizons. The soil is arranged in layers or horizons during its formation.

1. stabilize the stone foundation by replacing the lost mortar. 2. diagnose the cause of mortar loss (such as a gutter spill-over or improper downspout nearby) and fix it. 3. inspect the basement or crawl space and structure for signs of additional foundation movement, damage, or need for repair.

sized. The sand is then carried by a screw, which separates the sand from the water, to a conveyor belt, which carries it to a storage area. Water that is used in the plant is pumped from a freshwater pond. The discharged water is then pumped into a settling pond. A crushed stone plant differs somewhat from a sand and gravel plant. Raw material is
