5/8″ Minus – Black
DESCRIPTION:
This graded mix includes mechanically crushed dark rock, up to 5/8" and all fine pieces. Given its rough edges and angular pieces, this material works great as a binder, since it packs down tightly and stays in place, making it ideal for unpaved parking areas or to fill behind retaining walls. This is also commonly referred to as crushed rock or driveway rock.
USAGE:
Provides a clean look and weed suppression in landscape borders or rock garden beds. Often used as a top layer for residential driveways.
1 1/4″ Minus – Black
DESCRIPTION:
This is mechanically crushed rock, screened to 1 1/4" in size and including fines. Darker in color and with more variation than natural grey rock. The larger rock pieces, as well as the presence of fines, allows for deeper compaction, making this useful in road bases, heavy equipment parking and storage, and erosion control.
USAGE:
Use as a base material for concrete or asphalt. Works well as a parking base for RV's or trailers. Stays in place better than smaller rock for erosion control on slopes or in ditches.
1 1/4″ Clean – Black
DESCRIPTION:
This is a mechanically crushed rock product, graded to 1 1/4"pieces and washed to remove fines. The lack of fines and angular edges allow for stability without compaction, making this material a good choice in small to medium drainage applications, such as around septic systems and foundation drains.
USAGE:
Use as a top layer for muddy driveways or parking areas. Useful as a foundation material, particularly to improve drainage. Large angular pieces present well in landscape applications.
2″x4″ Quarry Spalls
DESCRIPTION:
This is an angular, natural rock material, cleaned to minimize fines, and ranging in size from 2" to 4". Since fines are minimal, this product is especially useful in areas that are soft and wet, due to the large pieces and superior drainage. Use this in construction entry points, large-scale erosion control, and utility access roads.
USAGE:
Perfect for adding drainage and stabilizing soft, wet ground. The angular pieces work well for erosion control. Provides a rugged attractive look in landscaped gardens. Used for check dams for erosion control
1 ½” Clean – Black
DESCRIPTION:
This is a mechanically crushed rock, naturally dark in color, graded to 1 1/2" and washed to remove fines. The large angular pieces provide a stable layer that does not compact. This material is especially useful in large areas where moisture control is necessary, such as septic fields, heavy drainage areas and erosion prone slopes.
USAGE:
Use in septic fields for superior drainage. Often used as a landscape rock.
3/4” Minus – Black
DESCRIPTION:
3/4" crushed rock with fines. Dark aggregate that has been crushed. Fines work as a binder for compaction. Does not pack as tight as the 5/8" Minus.
USAGE:
Better for a softer area than 5/8" Minus. Can be used as a pavement sub-base or road base. Typically used for commercial driveways or parking spaces for big trucks and RV's
Fine Sand
DESCRIPTION:
This Fine Sand material is a grey sand product. It functions well as the stabilizing layer for pavers and pathway stones, once the ground is leveled and prepped and stones are laid. Sweep this into the gaps between finished stones, once level, to help lock pavers in place. Since this product is also suitable for play area applications, it is commonly referred to as Play Sand.
USAGE:
Often used for stabilizing pavers, stepping stones or flagstones. Suitable for sandbox use. Can be used for lawn top-dressing and to improve soil drainage.
5/8″ Clean
DESCRIPTION:
This is a mechanically crushed, light grey rock with no fine material, allowing it to function well in areas that need better drainage. Containing pieces 3/8"-5/8" in size. Lack of fines prevents compaction, making this is good choice for drainage purposes. Commonly referred to as 5/8" washed.
USAGE:
Presents well in rugged pathways. Use to backfill retaining walls to prevent hydrostatic pressure.
