Folks, we are currently doing a design in a newly constructed development. The bid is $15,000 to give you an idea on the sincerity from the customer. They have ZERO grass-they want ZERO grass. The yard is approximately 10,000 sq. ft. The condition of the soil is clay and sand. (Terrible.) Since nothing grew there initially, we graded the slope to 4 degrees for water drainage to the front of the property towards city drainage. We place River Surge (1-6") down in place of the grass. All is well at this point...so we thought. Then it rains after 10 days of no water at all. The soil turns to 'muck' and the rock is slowly sinking in to the soil. Prior to that rain,you couldn't get a shovel in the soil so my thought was it was compacted. Well, without adding more rock to stabilize the base, is there another alternative to limit the movement of the base layer and limit the 'muck' in the future? The customer has been great so we want to do the right thing. We have done this last year and didn't have these problems rain or shine. What can correct this? Thanks alot in advance.
