How to Set a Concrete Foundation Form

Concrete foundation forms are necessary for making sure the concrete slab is poured straight. The form keeps the patio or house foundation plumb and square, providing the form is plumb and square. A concrete foundation form is laid and secured prior to pouring concrete. It is a simple process and requires very little skill. If you are considering adding a concrete slab or patio to your property, and you need a few informational tips, read through the following steps.

Things You'll Need

• 1-by-6 form boards Shovel Bundle 12-inch wood stakes Hammer Double headed nails

Instructions

1. Purchase 1-by-6 boards, one for each side of your foundation form. Slabs are usually 8, 10, or 12 feet so purchase your boards accordingly.

2. Dig out 6 inches of dirt where you will pour your concrete (4 inches is for the concrete and 2 inches is for sand). Sand is moistened and compacted under the concrete to provide stability.

3. Stand the boards on their sides along each side of the layout. The form will create either a square or a rectangle. It is possible that your house wall will be one side of the form.

4. Purchase a bundle of 12-inch wood stakes. Place them behind the boards a foot apart and hammer them into the ground. These stakes support the foundation boards and keep them from falling over.

5. Hammer a double-headed nail through each stake into the foundation form boards. This adds extra support. The nails are easy to remove once the concrete is poured.

6. Use a tape measure and a plumb line to make sure your form is square at each corner.

Tips & Warnings

• Never pour your concrete until all the forms are square and secure. Once the concrete is poured, it's to late to make changes.

• When securing your stakes to the form boards make sure to use double headed nails. Single head nails hammer flush with the wood and are difficult to remove.
