Gravel is a loose aggregate composed of rock fragments. It can be formed naturally through weathering and erosion or produced by quarrying and crushing rocks such as limestone, sandstone and basalt.
There is a wide variety of types of gravel including pea gravel, crushed stone, marble chips, quarry process, Jersey Shore gravel and river rock. Available in a range of sizes and colors, gravel has numerous commercial uses. Most commonly, gravel is used for driveways, road surfaces and concrete manufacturing. Gravel is also used for landscaping, railroad ballast, construction fill, water filtration, roofing shingles and winter road treatments.
Fill dirt is a natural, unscreened, earthy material that may contain a mixture of rocks, sand and stones. Typically a subsoil, fill dirt is nearly free of organic material to minimize settling.
Fill dirt is primarily associated with filling depressions or holes in the ground, but it has a wide range of uses. Fill dirt is used for highway shoulders, low-lying construction sites, landscaping projects and pool installations. From building runways to creating islands, fill dirt is essential for numerous construction and renovation applications.
Rebar is a reinforcing bar made from alloys and steel and used to help concrete withstand tension forces. When used with poured concrete, rebar can increase strength, reduce thickness and help reduce cracking and breaking.
Rebar is rust resistant and manufactured with ridges to help poured concrete adhere easily to the steel surface. It is often used in construction projects including buildings, roofing and driveways.
Sand is a loose, granular material. It is naturally formed through the erosion of siliceous and other rocks. Sand is found at beaches, riverbeds and deserts. It is one of the most widely consumed natural resources, second only to fresh water.
Available as a natural material or washed and screened, sand is a versatile material. Sand is ideal for base leveling and necessary for mixing concrete. It can also be used in landscaping projects, as fill for volleyball courts and playgrounds or to embed pipes underground.
Made from cast concrete, concrete blocks are a common building material. They are comprised of cement and aggregates such as sand or gravel. Cinder blocks may also contain fly ash or bottom ash.
Concrete blocks provide insulation from sound, heat and cold and are unaffected by termites and extreme temperatures. They are often found in load bearing walls, house foundations and basement walls, fire-rated partition walls, security barriers and landscaping.
Crushed Recycled Concrete
Crushed recycled concrete is concrete aggregate from demolition sites that is processed through a crushing machine then sorted by size. Using crushed recycled concrete helps keep construction costs down and minimizes waste dumped in landfills.
Smaller pieces of crushed recycled concrete are commonly used as sub-base gravel or as a base layer for asphalt pavement. If it is free from contaminants, the crushed recycled concrete can be used to mix new concrete. Crushed recycled concrete can be used for riprap revetments to prevent erosion, as a substitute for landscaping stone and mulch or as retaining walls.
