Angle brackets are the fastest and easiest way to level differences in height. Please note, that grown soil or frost-proof material that has to be integrated, must be sufficiently compacted according to the static requirements. Grown or filled up soil is to be checked by the site manager for soil properties and load-bearing capacity, which is defined by statics.
The standard calculation of the angle brackets is based on the assumption that the foundation is laid on grown soil: backfilling: γ(gamma)=19kN/m3, ϕ´k(phi)=35°. Should this not be the case, the soil conditions have to be analysed by the responsible site manager.
