Crushed concrete backfill Earthwork/grading engineering

Jan 27, 2007· Clay backfill would be a no no in this instance as the walls aren't filled solid and I'm afraid the pressures would be too great. The slab will be 5"-6" thick and be reinforced to account for loads and the eventual settling of the fill below. The crushed concrete pieces are roughly golf ball to tennis ball in size and VERY VERY irregular in shape.

backfilling a foundation Ask the Builder

Walls = Wide Beams. Backfilling a poured concrete wall or even a masonry concrete block wall can be very risky if two other tradespeople are not finished with their work. The basement slab and the first floor that sits on top of the foundation should be complete before backfilling proceeds.

Effects of Backfill Soil on Excessive Movement of MSE Wall

Dec 06, 2012· The construction of MSE walls is cost effective, requires less site preparation, and is technically more feasible compared with conventional concrete retaining walls. However, use of backfill with high fine content and poor drainage behavior can cause excessive wall movement or even failure. The current paper presents the case study of a MSE

Retaining Wall Basics Landscaping Network

The taller a wall is, the further below ground level it should be set. Crucial for supporting the rest of the wall, a good base is made of compacted soil and at least a six inch layer of compacted sand and gravel. Backfill; Second, a retaining wall must have properly compacted backfill. Backfill refers to the dirt behind the wall.

What Size Gravel Behind Retaining Wall? CR4 Discussion

Dec 14, 2010· What I bought was crushed concrete as it is just for drainage between the wall and retained earth with no crushed concrete (stone) showing. I put about 6 to 8 inches thick between wall and earth with a good commercial grade weed barrier separating the stone and earth, this keeps the earth from filling the stone (crushed concrete).
