About this tool.
Is the simulator accurate?
It uses simple, realistic ratios for soil absorption and drain capacity to show how the pieces interact. Real yards vary, which is why we visit.
Why does clay flood faster?
Clay absorbs water very slowly, so most of a heavy rain runs off or sits on top.
Can I send my setup to you?
Yes. Use the form below the tool and we will take a look.
