Prepare for this activity by stretching well and always lift using your arms and legs, not your back Shims (shown far right), or smaller stones, help level unsteady larger pieces. Map out the design by digging a trench about 6" deep and as wide as

It is the least pressure which would cause shear failure if the supporting soil immediately below and adjacent to a foundation. The ultimate bearing capacity is defined as the maximum gross pressure intensity at the base of the foundation at which the soil does not fail in shear. When the term bearing capacity is used, it may be understood to be the Universal Building Code

Rock structure includes joints, beding planes, folds, fractures, and faults. Rocks containing these structures will be easily subjected to weathering. There are certain elements which are included in rock composition. Some rocks will weather quickly and some slowly e.g. acidic rocks weather more quickly than basic ones. It includes the meteorological elements effect on rocks

It is the process of weakening rock and producing a rock waste or soil cover. Weathering occurs when rocks and minerals comes in contact with the atmosphere, organic life and suicidal water. Essential feature of weathering is that it affects rocks in-situ (in place) and no transportation of material is involved. A part of rainfall always snips into the soil on the covered rocks
