Isolated footings, strip footings, combined footings, etc. How far is it from the center of the interference pattern?(b). The first minimum in the electron count occurs at detector X. The greater the bearing capacity of the soil the lower the width of the strip footing needs to be. The purpose of providing a foundation to a structure is to distribute the load to the soil in such a way that the maximum pressure on the soil does not exceed its permissible bearing value and at the same time settlement is within the permissible limit. Pros Sometimes piles are pushed into the weakened level of the soil to increase the bearing capacity of the soil. Strip- disadvantages. The advantage of a deep system is that it is a more permanent foundation repair because the piles are bearing in the more stabile soils.

Trench fill foundations should be greater than 500mm thick. It is structurally a reinforced concrete slab spread over a whole This can be overcome by using suitable trench supports. Generally speaking, foundations are classed as either deep foundations or shallow foundations, and the choice of what type of foundation to use on any construction project is dependent on a number of factors, including the building itself, ground conditions, access, budgets and timeframes.
