Multiply the area by the depth of the excavation to obtain its volume: 36 * 0.5 = 18 cu yd . The volume of sand required is equal to the volume of excavation.

How much dirt does it take to fill a trench?
Length in feet x Width in feet x Depth in feet (inches divided by 12). Take the total and divide by 27 (the amount of cubic feet in a yard). The final figure will be the estimated amount of cubic yards required.
How much fill sand do I need?
To determine how much sand topdressing you need to cover an area: Measure number of square feet in the area. # of square feet x depth of application in inches x 0.0031 = cubic yards of topdressing needed for surface coverage. # of cubic yards x 1.35 = # of tons of sand needed.
How do you calculate backfill on a trench?
The volume of a rectangular cubed shape is found by the formula v = l x w x d, where v represents volume, l is the length of the trench, w is the width and d is the depth. Applying the numbers to this formula (8x 50x 6) the cubic footage of the example area is 2400 cubic feet.
How do you calculate sand backfill?
To fill a backfill of 10 ft length by 5 ft width to the 2 ft depth, for sand calculation in cubic yards, multiply the three dimensions length, width and depth together to find the number of cubic feet, then divide by 27 to find the number of cubic yards, such as 5 ft x 10 ft x 2 ft = 100 ft3 (cubic feet) ÷ 27 = 3.7
How do you settle dirt in a trench?
Place the flat end of a hand tamper tool on top of the soil in the trench. Pick up the tamper and hit the surface of the soil with it using firm pressure to pack the soil down. Repeat the process over the length of the trench until all of the soil is compacted.
How do you compact soil in a trench?
- After soil is backfilled into a trench, the loose material is compacted using some mechanical means, such as a compactor, an excavator, or a “jumping jack”-type compactor.
- With the jetting technique, you pump the water under pressure and use the force of the jetted water to move the bedding or backfill material around.
How much does a ton of sand cover?
A ton of sand yields around 0.75 cubic yard or 20 cubic feet volume, which will cover approximately 120 square feet area for a standard 2 inch depth, or 240 square feet with 1 inch deep, or 80 square feet with 3 inches deep, or 60 square feet at 4 inches deep.
How many yards are in a ton of fill sand?
There are 0.75 cubic yards in a ton of sand. For estimating purpose a yard of sand weighs approximately 2700 pounds, and 1 ton of sand weighs is equal to 2000 pounds, so number of cubic yards in a ton of sand = 2000/ 2700 = 0.75 cubic yard, so, there are 0.75 cubic yards in a ton of sand.
How much sand is in a dump truck?
While there is room for variance, most full-size dump trucks have a capacity of between 10 and 16 cubic yards.
How much does a sand backfill trench cost?
Includes planning, equipment and material acquisition, area preparation and protection, setup and cleanup. For a basic project in zip code 47474 with 25 linear feet, the cost to Backfill a Trench starts at $2.76 – $11.64 per linear foot. Actual costs will depend on job size, conditions, and options.
What is the thickness of the backfill layer?
Cohesive backfill shall be deposited in horizontal layers not exceeding 200 mm in thickness. Every layer shall be tamped in place and well compacted by means of mechanical tampers before the next layer is deposited.
What is the best material that can be used for backfilling?
Backfill refers to the material used to refill an excavated hole, and it is typically used to strengthen and support a structure’s foundation while also promoting better water drainage. Stone is a great choice for backfill because it’s durable and offers great drainage; however, some stones work better than others.
How do you calculate fill?
You can calculate fill rate by counting the number of orders that you were able to fulfill at one time. Then divide the number by the total number of orders you received and multiply the sum by 100.
How long does it take to trench 100 feet?
The short answer is a good working trencher of 100 linear feet will take roughly 12 hours to dig. You can calculate the work period by multiplying the linear feet you need to dig by 0.12. However, how fast you finish depends largely on the trencher power and the soil environment.
How do you compact sand without a compactor?
A lawn roller or hand tamper can be used to compact the moist soil, or you can walk over it.
How long does it take for trenches to settle?
If left dry, clay and silt will settle rather quickly, i.e., 1-2 years. If they come in contact with water, they can settle in just a few months. However, we don’t recommend using these soils around your foundation for structures or your lawn.
Can sand be used as backfill?
You can use sand or gravel for backfill, as both are easy to use. They both discourage weeds from growing there, and they don’t take a lot of maintenance to look great. Backfilling is the technique of filling those holes all the way in, and you can use sand, gravel, or other materials for it.
Can you backfill a trench with water in it?
While backfilling in the rain can moisten the soil to help with compaction, it’s not a good idea to backfill if the rain is heavy. Hard rain will put your safety at risk and make for a muddy mess. Backfilling a small project like a pond or small trench can be accomplished in light rain.
How much is a truck bed of sand?
A dump truck load of sand costs $300 to $700 on average, which includes delivery. Prices depend on the size of the truckload (typically 8 to 17.5 tons) and the type of sand such as river sand, arena sand, play sand, fill sand, or all-purpose construction sand.
What does 1 ton of sand weigh?
According to US customary measurement system, weight of 1 ton sand is about 2000lb and a cubic yard of sand weigh around 2700lb, regarding this, how many cubic yards are in a ton of sand, generally there are 0.74 cubic yards in a ton of sand (2000 ÷ 2700 = 0.74).
