Pile Foundations Types of Piles Cassions - Understand

Pile foundations are used in the following situations When there is a layer of weak soil at the surface.This layer cannot support the weight of the building,so the loads of the building have to bypass this layer and be transferred to the layer of stronger soil or rock that is below the weak layer.How Long After a Foundation Is Poured Can You Build?Poured concrete foundations are an alternative to block or treated wood foundations.The process involves building a form to hold the concrete in place,installing reinforcing rods and then pouring the concrete.Once cured the concrete provides a secure and stable foundationGuide to Foundation Footings Building CodeNobody can deny the need for a good house foundation.Improperly built foundation footingsunlike poorly installed gutters or gapped hardwood flooringcan eventually bring down the house.Building codes have a few things to say about foundation footings.Like any code recommendations,these are not how-to guides to building footings so much as parameters you need to observe,based on local
