Excavation trenches might seem simple but if you arent using a trench box or shoring then your trench must be excavated to the proper angles of repose (the angle made between the sides of your trench and the level ground around it) for the type of soil you are excavating.
Sound complicated? Dont worry, Trench Right makes these calculations super easy! Just enter in some information about your trenchs dimensions, the soil type, and your penetrometer reading (in TSF) and well do the rest.
