Pier Foundations

Pier foundations are used while the loads to be transmitted are heavier than loads those could be accomplished through piles. They are essentially bearing in nature and are not slender. They are constructed through making large shafts. In large sized piers, it might also be possible to inspect the strata before concreting the shaft. Drilled piers are constructed through drilling large diameter holes and are particularly suited in dry soils whereas a firm stratum of rock could be met along with reasonable depths (Figure 18).
