Frequently Asked Questions

QuickCreteWhat size rock do we use?

Our standard rock is ¾” minus. We also ofer ⅜” pea gravel.

How long does it take for concrete to set up?

It depends on several different factors but normally you can walk on carefully (no twisting) in 12 hours. In 48 hours you can remove forms. In 7 days you can park a car on, you will have 70% of strength. In 28 days concrete reaches its full strength.

How thick does it need to be?

We recommend a minimum 4 inches on driveways, patios, sidewalks, and most slabs.

Do we need to use rebar or fiber mesh?

It depends on the use. It is usually recommended for driveways or other heavy-use areas to reduce cracking.

Do we need to have a gravel base? If so, how deep should it be?

We do recommend it. A compacted gravel base of equal depth to your slab is best.

What tools do I need? And where can I get them?

You should have a screed board, bull float, edger, and hand trowel. You can buy these tools at any of the building supply stores or you may rent them at most rental stores.
