I am currently building a new home and have heard that I can have the builders put pvc pipe or some kind of soaker hose in or around the new foundation as it is being poured to keep the soil moist and keep the foundation from shifting later. Does anyone have any ideas or suggestions or information regarding this?

I've heard of people using soaker hoses as part of some remedial action, but if your foundation has been designed with the correct reinforcement and depth (and the subgrade has been tested for bearing capacity and plasticity etc), it should not be necessary.

I've heard of this before, but it is not to prevent the foundation from shifting. This is done afte the foundation has been backfilled. The backfilled soil is usually not compacted very well and is very loose. It will have a tendency to settle over time. By soaking this area with a hose, you are helping speed up that settling process. This should eliminate the need to add dirt around the foundation later after the landscape beds and other areas around the house have sunk.

The problem with expansive clay soil is it shrinks when it becomes dry. During extremely dry periods a foundation to a structure can very well settle and even crack or fail. The soaker hose can be used and is being used by quite a few people to solve this problem but this is not the best solution. An underground irrigation system that controls the moisture content in the soil around the foundation by adding water only when the moisture content is too low can be very useful when dealing with this type soil.

Using a soaker hose to help compact the soil could help over an extended period of time to some extent but this is not the norm for compacting soil around the house and far from being adequate for this purpose.
