Dealing With Wet, Clay Soils
 |
| Kevin and Shawn prepare the base for a new paver patio. |
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.
