CAS Slingers Backfill Retaining Walls 15x Faster
A CAS Slinger uses its conveyor system to rapidly and accurately spread gravel up to 15x faster than conventional equipment. It can place material from a distance in a wide range of patterns, making it ideal for construction and landscaping projects of any size and scope. With a minimal crew required to operate a CAS Slinger, it saves time and money by delivering and placing material faster, further, and more efficiently than traditional labor.
Frequently Asked Questions
How do you backfill a retaining wall?
Lay your base of compacted native soil.
Compact the soil to ensure that it is secure and firm.
Fill the next six to twelve inches with aggregate or gravel.
Tamp the gravel or aggregate to ensure a sturdy base.
Fill the remaining six or so inches with the compacted native soil to allow grass and plant growth around the base of your retaining wall.
Many sites utilize a CAS Slinger, which is the fastest and most accurate way backfill a retaining wall, capable of placing material up to 15 times faster than other methods.
What do I use to backfill a retaining wall?
A CAS Slinger is optimized for backfilling a retaining wall as it can place aggregate material many times faster than other construction methods. The best materials for backfill are native soil for the base and top, with gravel or aggregate forming the body of the backfill between the native soil.
Can you backfill a retaining wall with dirt?
The best material to backfill a retaining wall is a combination of gravel and native soil, with soil on the base and top and gravel forming the body of the backfill. A CAS Slinger is the ideal piece of equipment to quickly and accurately place aggregate and soil material.
How long should you wait before backfilling concrete retaining wall?
Concrete should cure minimum of seven days.
ASTM C 150 Type I cement - seven days
ASTM C 150 Type II cement - ten days
ASTM C 150 Type III cement - three days
ASTM C 150 Type IV or V cement - 14 days
ASTM C 595, C 845, C 1157 cements - variable
How do you calculate backfill on a retaining wall?
Multiply the length of the wall by the desired height, then divide this number by 81 to determine the amount of backfill gravel needed. Add the backfill amount to the base amount to determine the total cubic yards of gravel necessary for completing the wall.
What do you backfill a retaining wall with?
A CAS Slinger is optimized for backfilling a retaining wall as it can place aggregate material and soil quickly and accurately. The best materials for backfill are native soil for the base and top, with gravel or aggregate forming the body of the backfill between the native soil.
What is backfill?
Backfill refers to the dirt behind the wall. In order to provide proper drainage, at least 12 inches of granular backfill (gravel or a similar aggregate) should be installed directly behind the wall. Compacted native soil can be used to backfill the rest of the space behind the wall.
A CAS Slinger is able to easily place gravel and soil quickly and accurately, making it the ideal equipment to use when backfilling a retaining wall.
What type of backfill should you use?
Our experts prefer crushed stone for the base rather than naturally occurring gravel dug from a pit. Crushed stone is a little more expensive. However, it provides better drainage, and because of the sharper angles on the stone, it requires less compacting, and once it's compacted, it stays that way.
