Concrete Patio Base
I don't think this is the right forum but thought I ask in case anyone has any experience with this.
Most sources recommend 4" of compacted gravel for a concrete patio base. I've seen recommendations up to 12", which is certainly overkill.
I have a friend that is pouring a concrete patio as a side job for me. He does this for a living so I trust his experitise. However I checked the base he put in and its only 1" of compacted gravel.
Before I say anything I wanted to get some opinions about the situation.
The house was cut into a slope so this soil under the gravel base is a sandly clay like soil with alot of rock. Figure I share that as it may impact the required depth of crushed gravel.
