What is the difference between mass concrete and piled underpinning?
In essence, mass concrete underpinning involves men digging under the house foundation and then filling up the hole with concrete. As the depth increases so do the difficulties and the risks. Mass concrete is not suitable in some ground conditions where it is only safe to use piling options. Piling is a much more economical and safe method of providing deep foundations. In very basic terms piling is like banging a big nail into the ground and then attaching the house foundation to it. The methods for piling structures does vary and can be quite complicated. If your house is to be piled and you are unsure what this means you should speak with your engineer.
