“When getting a quote it’s important to know what you’re getting.
What’s under the concrete? What’s the re-bar like in the concrete? What kind of concrete is used?
We use road-base foundation under the concrete (crushed concrete and gravel).
Many other companies use cushion sand, because it’s cheaper. The problem is that in time it will wash away.
We use 3/8 inch rebar on 16 inch centers. Most other companies put it at 24 inches.
The concrete we use is 3500 psi (standard is 3000).”
