Belly Dump Trailers

Belly Dump Trailers

Belly dump trailers, otherwise known as bottom dump trailers, are aggregate trailers with a clamshell gate located on the bottom of the trailer. In most cases, the driver is able to open and close the clamshell gate to release the material out of the bottom of the trailer. The trailer is very efficient and does not require the operator to stop in order to dump. Additionally, because the trailer remains planted firmly on the ground, there are very few dangers associated with dumping a belly dump trailer. These types of trailers are most commonly used in stockpiling, material transport, and asphalt paving.

Belly dump trailers will release their full payload in a uniform line approximately 25’ long. The material is partially spread, making it easy for a bulldozer or loader to manipulate.

While belly dump trailers are praised for their safety and efficiency, they do have their limitations. Belly dump trailers typically utilize construction materials focused on reducing weight, making carrying rough or large aggregates difficult or impossible; because belly dump trailers have to drive over the materials they dump, they are best used to transport fine aggregates.

End Dump Trailers

End Dump Trailers

An end dump is a trailer that stands up and delivers its payload through a rear gate. Because end dump trailers must stand their trailer up, they are notoriously unstable and require level ground for safe dumping. The trailers usually feature a box or rounded design, depending on the trailer’s intended use. End dump trailers are best used in hauling both road and building construction materials, agricultural products, and aggregate stockpiling.

End dump trailers feature a heavy-sided design, allowing the carrier to transport larger loads than other aggregate trailers. Depending on the trailer’s construction material, they also offer more flexibility. Steel end dump trailers are great for demolition haul off, but their heavyweight doesn’t allow for as large of a payload. Aluminum end dumps cannot handle rough or overly large materials, but due to their lightweight design are excellent at transporting fine to small loose aggregates with maximum payloads.

Tandem and Super dump Trucks

Tandem and Super dump Trucks

Tandem trucks and super dump trucks do not require a trailer. These units are extremely flexible and can carry a wide range of payloads, from fine aggregates to demolition haul off. Tandem and super dump trucks are what the layman likely thinks about when thinking about a traditional dump truck. The truck will feature a cap where the driver sits and, directly behind the driver, will be the truck bed. When dumping, the truck bed will raise and release the payload out of a rear gate.

Tandem, aka Dump Truck

Tandems are used for transporting loose material such as sand, gravel, or demolition waste. The typical dump truck has an open-box bed, which is hinged at the rear and equipped with hydraulic rams to lift the front, allowing the material in the bed to be dumped on the ground behind the truck.

Tandem trucks are excellent options for construction projects, residential deliveries, or any aggregate delivery require the shorter wheelbase and flexibility the truck provides due to its lack of trailer. Tandem trucks have one disadvantage: they have low payload capacities. While an end dump tractor-trailer combination has an average payload of 25 tons, the typical tandem will carry between 15-17 tons.

Super dumps provide the flexibility of a tandem but with the payload of a traditional tractor-trailer. These trucks use an additional load-bearing axle at the rear of the truck to evenly distribute weight according to the legal requirements. While a tandem is limited to 52,500 lbs, a super dump can have a total weight of 64,500 lbs. While empty and in transit the trailing axle stores above the vehicle and can be raised during the dumping process. Super dump trucks can be outfitted with up to 3 additional axles, for a total of 7, increasing their payload capacity to 80,000 lbs.

Select Fill

Select Fill

Select fill is similar to common fill but is a more even mixture of clay and sand. Select fill typically provides more predictable results due to the extra processing it undergoes before being sold to customers. Select fill is most often used when constructing building pads, but can also be used as backfill. While often cheaper than top soil, select fill is best used on construction sites or where heavy equipment is available.

Common Fill

Common Fill

Common fill is a cost-effective way to fill large holes, low spots, or to bring upgrades. The material is generally rocky but is cheaper than the alternative select fill. This product is mostly used in very large projects. The material typically has a high flay content, is dug straight from the ground, and loaded directly into a belly dump, end dump, or tandem dump truck. It is best used on construction sites or where heavy equipment is available to manipulate and break down the material.

Top Soil

Top Soil

Top Soil is the clay, silt, sand, and other material that is removed from the top 12” of earth. Top soil has the highest concentration of organic matter and is typically used to reshape the landscape in areas where plant growth. Top soil is excellent for improving gardens and lawns but is also used for surface grading near buildings.

Silica Sand

Silica Sand

Silica sand is exceedingly rare in central Texas and is the most expensive. The material is available in a very pretty white coloring but is mostly used in industrial applications due to its high cost. Silica sand is quartz that has been broken down through erosion. Silica sand is a primary ingredient in glass manufacturing, metal casting, metal production, chemical production, filtration, and has many other construction applications.

Manufactured Sand

Manufactured Sand

Manufactured sand is produced by reducing larger pieces of aggregate into sand-sized pieces. Manufactured sand is neutral in color, coming in a range from tan to gray, and is used in areas where natural sand is not available or when transportation is not cost-effective. Unlike washed sand, manufactured sand tends to come in irregular shapes as a result of the pulverizing process. While manufactured sand can be cost-effective, it is generally considered to be an inferior product when compared to washed sand.

Washed Sand, aka Concrete Sand

Washed Sand, aka Concrete Sand

Washed sand, otherwise known as washed concrete sand, is a light off-white color material which is screened and washed to remove any impurities. Used often as a building material, it is popular with golf courses, as a construction base, in pool construction, and is mixed with cement and aggregate for concrete work.

Sand & Soil We Carry

Sand & Soil We Carry

We sell manufactured sand, washed sand, and can source silica sand for customers in Waco, Bryan, and Austin, Texas. While the majority of our sand products are used in ready mix operations, they have many different applications.

RipRap

RipRap

Riprap is a large category of rocky material typically placed along shorelines, bridge foundations, steep slopes, and is an excellent choice for protecting landscapes and structures from erosion. Riprap ranges from 6 inches to over 2 feet in diameter and is known for being an excellent way to armor, stabilize, and protect the area it is applied.

River Rock

River Rock

River rock is a washed gravel known for its smooth, rounded texture and wide range of applications. The rocks will come in a mixture of sizes, but will typically be between 1” and 2” in diameter. River rock is multicolored and contains a mixture of gray, tan, white, and deep reds. The material is excellent for use in gardens, as a walkway, around patios, in residential construction, and as decoration. Due to the rounded nature of the rock, they tend to sit very loosely, providing an excellent drainage solution.

Pea Gravel

Pea Gravel

Pea gravel comes in sizes from ⅛” to ⅜” and in a wide range of colors from brown, to gray, to white, and even translucent. The material is best used for walking paths, patios, driveways, and playgrounds, but can also be used in gardens to suppress weed growth. Pea gravel is rounded and smooth, thanks to natural erosion, and lacks the jagged edges required to hold the material in place. As a result, projects using pea gravel often need some type of edging material to keep the aggregate locked in place. Pea gravel is not recommended for roadways or driveways and is best used in decorative applications or in low-impact areas.

Flex Base

Flex Base

Flex base is a coarse material most often used for driveways and temporary roadways. Also referred to as base and caliche, the material is excellent for use under concrete and asphalt pavement projects. Although primarily meant to be used temporarily, the material plays an important role in the longevity of our roads, operating as the foundation upon which our roads and driveways are built.

Road Base

Road Base

Road base is used as the foundation of a road or driveway. It is typically used on projects where asphalt is not cost-effective or prohibited. The material is a mixture of coarse and fine aggregate and packs down very hard in the first few weeks. Road base is a very cost-effective solution for rural driveways and parking lots.

Utility Rock

Utility Rock

Utility rock is a flexible material used in pipeline construction, embedment, backfill, parking lot construction, pathways, decorative landscapes, and driveways. The material is typically tan to gray in color and approximately 1” in diameter. The material has sharp edges and is excellent in areas requiring drainage.

#57 Rock

#57 Rock

57 rock is a crushed stone aggregate used in a variety of construction and landscaping applications. The material is very gravel-like and will have a uniform size throughout. The material is sourced from natural rock deposits and typically has jagged edges resulting from the crushing process. The number 57 refers to the size sieve used to process the stone after crushing, producing aggregate between 1” and 1.5”. The stone may consist of granite, limestone, or washed gravel depending on the source location. The material is typically used in concrete applications but is often also found in sidewalks, driveways, and on many roads. Because of the stone’s angular shape, it holds formation and provides excellent drainage for retaining walls, underground pipes, sewers and utility lines.
