A square concrete form is a building tool that’s both simple and versatile. It is easy to use, so you can finish your project faster. With it, you can quickly create a square foundation or wall corners and use that foundation to build your entire structure.
Building a concrete form is the first part of this project. To create the square shape, you’ll use four pieces of wood to make guide lines for your form. Attach them together with screws. Drill holes in the bottoms of two boards, and insert PVC pipe into those holes. Cement is used to fill in the gaps between the boards and PVC pipes to completely seal off any gaps where water can leak through during rainstorms.
This is about how to build a square concrete form for a foundation. You should have some experience doing this before trying your first time. I’ve built hundreds of these so I know what works and what doesn’t work. There are many different ways to do this, but the most efficient way is to just follow instructions exactly as they are written here. Here we go.
Decide on the size of the form you want to build.
First, decide on the size of the form you want to build. The size of the form will be determined by the size of concrete you want to pour. The form should be a little bigger than the concrete itself. For example, if you want to pour a 10’x10′ slab foundation and have 3″ thick walls, then your square concrete forms will need to be 12″ longer and wider than 10’x10′. This will leave enough room for expansion as well as contraction due to temperature changes during construction.
- Solid footings should be at least 2 feet wider than their actual dimension (e.g., footings measuring 8″ x 12″ should actually measure 10″).
The wood studs should be placed along the outside of your form, not as a center support.
The wood studs should be placed along the outside of your form, not as a center support. The studs are used to support the form, not to hold it up. The form will be held up by metal stakes placed directly over where the studs are located. Once you have built your square concrete form and finished pouring your concrete in it, you can remove all of these supports except for one stake in each corner that will be used to lift the form up once it has been completed.
Place metal stakes at each corner and nail them to your form boards.
Now you’re ready to build your form. The first step is to place metal stakes at each corner of your square form, and nail them securely into the ground.
You’ll need a hammer for this job—you can use any old hammer, but if you want to do it right you might want to invest in a special stake-driving hammer (available at most hardware stores). These hammers have handles that are shaped so that when you drive a stake into the ground with them, they create an indentation or dimple in the earth around the stake on all sides—this helps keep it from moving around as much when things get busy later on.
A good rule of thumb is that your stakes should be higher than the top of your form so that it can be moved easily without damaging them—and make sure they stay securely planted in place until after pouring concrete has been completed so nothing gets damaged during construction process.
Make sure the metal stakes are higher than the top of your form so that it can be moved.
The stakes should be at least as high as the top of the form, so that you can move it with ease when you’re done. The stakes should also be long enough to go through all your form boards and at least an inch above them (depending on how thick they are).
When you’re done pouring your concrete, remove each board one at a time so that they don’t stick together when moving them.
Use 2 x 4s to make the bracing for your form. Use nails to attach them to the inside of your form boards.
It’s important to use 2 x 4s to make the bracing for your form. Use nails to attach them to the inside of your form boards. The top two pieces should be nailed into place at each corner, and then the bottom piece should be placed in between them, making sure it is centered with equal space on either side of it. Make sure that you have enough bracing so that you can move your square concrete forms around without worrying about them falling apart or breaking apart while they are being moved around during construction processes like pouring concrete or placing rebar in place before pouring concrete.
If you’re using multiple sheets of plywood, use a screw gun to secure them together. Make sure your screws are long enough to go all the way through 2 pieces of plywood.
Screw the sheets together with a screw gun, making sure that your screws are long enough to go all the way through two pieces of plywood. If you’re not sure how long they need to be, use the same size as some of those used in step 1 (typically 1.5 inches).
Don’t forget—if your concrete form is going to have cross-pieces (or other structural support), make sure they’re in place before you attach any pieces of plywood together.
Once you’ve secured all the pieces of plywood, place them onto your frame and nail them in place.
You’ll want to make sure your plywood is level, straight and perpendicular to the floor. If you have a bubble level handy, that will help ensure accuracy.
If you don’t have one of these handy, you can make an accurate square by using a chalk line or string line (both available at most home improvement stores).
Lay out your string line up against two opposite corners of the plywood so that it makes an X across your surface. Then take another piece of string line and tie it around one end of each piece so they meet in the middle and form a cross (like an X) with the two pieces coming together in the middle where they intersect at right angles. Next, use nails or screws to secure each piece along its outer edges down onto your frame—the cross formed by these pieces should be exactly perpendicular to them both vertically when looking from above as well as horizontally as seen from either side or below (if possible).
Add an additional layer of support by placing a 2 x 4 along either side of the bottom layer of plywood and nailing it into place.
Add an additional layer of support by placing a 2 x 4 along either side of the bottom layer of plywood and nailing it into place. These 2 x 4s should be placed at the same height as the plywood, and they should also be placed on the outside of your frame. Make sure you have enough space between them so that your form will fit snugly within them once it’s laid out flat.
Once you’ve added these pieces in, continue by building up another layer from scratch following steps 1-5 above until you reach your desired height.
