Drought condition impact on new slab
Drought condition impact on new slab
(OP)
We are experiencing a drought condition in Dallas that has left the area without rain for 60+ days. I am about start construction on a large home that will be on a "engineered" post tensioned slab on piers. The soil is black clay and I am concerned about the possibility of heaving once the water returns to the soil. Comments?

One method of preparing the site during dry weather is to build a small bund wall around the building perimeter and soak the area of the building foundation for a period of time to boost the soil water content and hence reducing the impact of heave. To be fully effective we generally need to have a damp follow up period after construction. If this is unlikely then try wetting the perimeter of the new building to help retain some moisture in the soil.
