 · Foundations start at the angle of repose. This enormously affects excavation costs and the costs of concrete for foundations and/or retaining walls. Not every block will have easements, but more often than not, there is a rear easement. Blocks back onto each other generally, so the easements will most often run along the back of one property.

Concrete angle of repose

Angle of repose - Wikipedia. The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0° to 90°.

Friction angle of crushed rock

 · If so, a quick way to guesstimate a friction angle is to pile the crushed stone on top of eachother and then measure the angle of repose. A true crushed stone slopes would fail by sliding parallel to the slope. When the slope angle exceeds the angle of internal friction, the stone grains should slide down the slope.
