Dealing with Wet, Clay Soils

When you dig in the dirt like we do, you occasionally find some unexpected things underground.  This patio project started as a routine excavation.  We removed the old concrete patio and found a spongy, clay subsoil that would not dry out.

If we were to build directly on this soil, our patio would settle and shift. Owner and Project Manager Corey Koch determined that we needed to reinforce the base material to stabilize the patio.  Corey is a Certified Paver Installer through the International Concrete Paver Institute training, the international authority on paver patio construction.

Corey’s training and experience told him that the answer to the problem was to add both lateral support and vertical support to the crushed rock patio base.  Our team installed Geo-grid to provide lateral support that keeps the patio from shifting from side to side. 

Then they enclosed the area with a woven landscape fabric to keep the base rock from sinking into soil, stopping any settlement.  This combination will allow us to bridge the wet clay and provide a stable base for the client’s paver patio.  We will show you more photos after the project is complete.
