How To Build Concrete Forms With Plywood

Plywood is a material with many different uses and this is just one. At the end of this article you will know how to construct concrete forms from plywood, in order to put in a garage. Building concrete forms is a very important part of the home building process. Concrete forms are used to build walls, remove protruding objects and create space for plumbing and other appliances. To build your own forms you need plywood as material, a saw to cut the plywood, wood screws and blocks.

A simple method of building forms, called the plywood form, can be used to build large retaining walls, swimming pools and other structures that require a rounded or curved shape. With plywood edging and some construction equipment, you can build any shape quickly and easily.

Concrete forms are used to hold freshly poured concrete while it dries. If you’re planning a home improvement project that involves pouring concrete, then you will also need to use forms. You can build your own concrete forms on the job site with 2x4s and sheets of plywood, but doing so is often time consuming and labor intensive. It’s usually easier to rent premade forms from a tool rental company or purchase them at a local home improvement centre. There are many different ways that you can build your own concrete form, so it’s important to ensure that your method is appropriate for the size and scope of your project. A small form for a 4-inch by 4-inch post doesn’t require much in terms of materials, but large projects will benefit from more heavy duty supplies like exterior grade lumber and nails rather than screws.

Determine the dimensions of the footing.

Determine the dimensions of your footing. Subtract the thickness of your plywood sheets from the dimensions of your footing to determine its actual surface area. For example, if your form has an outside dimension of 10 feet by 12 feet, and you are using 1/2 inch thick plywood sheets, subtracting 2 inches from each length would give you a surface area for this form of 9 feet by 11 feet 6 inches. Cut four pieces of plywood to these dimensions.

After measuring your footing, subtract the thickness of your plywood sheets from its length and width. This will give you the actual surface area that you can use to cut the plywood sheets.

Cut four pieces of plywood to the dimensions of your form.

To make your form, you’ll need to cut some plywood to the dimensions of your footing. Use a circular saw for all cuts, as it can cut through multiple layers of plywood easily. If you don’t have access to one of these tools, however, you can use a jigsaw or miter saw instead. Finally, if you have access to a table saw at home or work then feel free to use that instead.

Fit the plywood panels together.

Once you’ve built the forms, it’s time to fit them together. Fitting plywood panels together can be tricky, so there are a few things to keep in mind when working with this material:

  • Make sure each panel is flush at the corners.
  • Make sure each panel is straight (there shouldn’t be any noticeable “bowing” or “twisting”).
  • Make sure all of your panels are level with one another and parallel with each other (i.e., they sit flat on the ground).
  • Make sure all of your corners match up perfectly, as well as everything else that needs to get lined up perfectly like the front edge of one form meeting the back edge of another form.

Level and brace your forms, then nail them into place.

  • Level and brace your forms, then nail them into place. When you’re using plywood to build concrete forms, it’s important to get them in the right position before nailing them down. To do this, you should use a level and a framing square (or a framing hammer) to make sure they’re level and square.

Once your forms are properly positioned on their bases, use either a framing nailer or regular nails to secure them together along edges where they meet at right angles.

Build a form for the concrete footing, using 2-by-4 lumber and dimentional lumber for straight boards.

Once you have your form built, use screws or nails to secure it together. Use a level as a guide to make sure that the form is evenly spaced and at the right height.

Nail a series of 2-inch by 4-inch boards around the perimeter of your framing to hold it together.

  • Set the 2x4s in place and level them with one another by marking a line on each board and then using a level to make sure they are all even. Use a nail gun to secure them together in 4-inch increments around the perimeter of your framing.
  • If you’re using plywood, do not attach it yet you will be attaching it later, after you’ve built your forms around the 2x4s and have secured them in place.

Building concrete forms is relatively easy; all you need are several sheets of ¾” CDX plywood, some 2”x4”s to use as boarders, and some screws or nails.

If you’re covering a large area with a slab or patio, it’s best if you build the form around the perimeter first and then fill in the middle with smaller pieces. This way, when you’re ready to pour your concrete, it will be easier to get all of those small edges filled in evenly without having any overlap that could cause uneven surfaces later on.

Final words

Hopefully, these steps have been helpful to you in your quest for the perfect concrete form.
