On the off chance that a
bedrock or rocklike material is available at a site inside a sensible
profundity, heaps can be reached out to the stone surface. For this situation,
a definitive bearing limit of the heap depends altogether on the fundamental
material; therefore the heaps are called end or point bearing heaps. In the
majority of these cases the important length of the heap can be genuinely
entrenched.
ArrowInstead of bedrock,
if a genuinely minimal and hard stratum of soil is experienced at a sensible
profundity, heaps can be amplified a couple meters into the hard stratum.
