Concrete is one of the most durable materials that can be used for home construction. It’s extremely strong, and it can easily withstand harsh weather conditions. Concrete walls are also very versatile, being used for both retaining walls and as a base material for poured concrete foundations. While concrete wall forms can look relatively straightforward, there are a number of things you need to keep in mind when working with this material to ensure your finished project is strong and stable. In this guide, we’ll cover the basics of how to make concrete forms by reviewing some of the necessary steps involved in building a concrete wall form:
The first thing you need to do is to prepare a flat, level surface for your concrete wall.
The first thing you need to do is to prepare a flat, level surface for your concrete wall. For example, if you were making a concrete wall in your backyard and wanted it to be 12 feet tall, choose the ground where it will sit. Then use stakes and string lines to mark off an area that is 9 ft by 12 ft (or whatever size wall you want).
After marking off an area with stakes and string lines, dig out enough dirt so that there will be 6 inches of space between the bottom of the soil and top of the ground when you are done digging. Next, tamp down this area until it is perfectly level using either a tamper or tamping tool.
Once tamped down, create a slope from one side of this area toward another by pouring water over one side; this will cause all loose material at one end of your site for forming concrete walls to slide toward other end where water was poured onto ground surface during preparation process above.
You will then build the forms to give your wall its shape.
To make sure the forms are properly aligned, use a laser level or a plumb bob and tape measure.
If you don’t have access to these devices, install stakes in each corner of the form. You can then measure from those stakes to ensure your wall has proper squareness and levelness.
To make your rebar grid, cut pieces of rebar to size using bolt cutters.

- Use a plumb bob to find the depth of the footing and mark it on the ground with stakes and string by driving them into the ground at right angles to each other at both ends of your form area.
- Check that your form’s alignment is level by using a bubble level on top of it (use two if necessary), making sure that all four sides are parallel with each other; adjust as necessary until they’re level.
- Check that you have a flat surface by using a 4-foot carpenter’s level lengthwise across all four walls; adjust as necessary until they’re flat or use shims under low spots if you won’t be able to use concrete for those areas (since it will cure).
To find the depth of the footing, set the bottom rail in place and use a plumb bob to establish where the ground is.
To find the depth of the footing, set the bottom rail in place and use a plumb bob to establish where the ground is. Mark the ground with stakes and add rebar to each stake. Add these stakes to your bottom rail, making sure that everything is level.
Once the footing is complete, you can start building your formwork.
Once the footing is complete, you can start building your formwork. This is a temporary structure made from wood or steel that supports the concrete during construction. The formwork should be at least as wide as the wall and at least as deep as it will be high once it’s finished. It may also need to be supported by horizontal beams called girders if there isn’t enough room for the length of your wall.
Once you have built your forms for walls, you can lay concrete on top of them in layers. For each layer, mix together a batch of ready-mix concrete with water according to the instructions on the bag until it has reached a consistency that allows drywall screws to sink into it without much effort (about ¼ inch). Place this mixture between two strips of wood called “gunnite pans” or “gunnite boards” that are connected together on top with cross bracing so they stay upright when filled with wet cement; these strips should be placed so they are flush against each other when stacked together vertically like bricks would be stacked inside an actual brick wall! If possible do not use metal braces because they could rust over time causing damage beneath where they were installed originally—this practice will make sure nothing deteriorates due to age either while under construction or afterward once finished being used regularly throughout life span.
Place a series of stakes along the entire length of your wall, making sure they are spaced correctly to allow room for all forms.
To start, you will want to make sure that you have enough stakes. The best option for this is to use a stake every 8 feet, or two meters. This will allow plenty of room for the forms as well as any rebar that needs to go in the wall. The stakes should be spaced evenly along your entire length of wall, with at least 2 feet between each one so they don’t interfere with each other when placing or adjusting them during construction.
You also need strong materials for these stakes. If possible, use metal so they can help support any weight on top of them without bending or breaking off easily like plastic ones might do if overloaded with large blocks falling onto them while building up walls over time (this also helps prevent cracking along surfaces where tension exists).
Make sure that each stake is plumb and level before setting it in place, as any mistakes here will transfer directly into your concrete wall.
Make sure that each stake is plumb and level before setting it in place, as any mistakes here will transfer directly into your concrete wall. This is a critical step! If you don’t get it right, you’re looking at an uneven wooden footing that could topple over and crush someone.
If the stakes are not level or plumb, the entire wall will be off-kilter from top to bottom—and if you don’t want an uneven surface on top of your concrete foundation (or worse yet: walls!), you’ll need to re-level everything before proceeding with pouring the concrete.
Treat your framing individually, leaving space between each one for rebar placement when required.
Treat your framing individually, leaving space between each one for rebar placement when required. The space around the form is where you’ll place your reinforced steel bars or rods to reinforce the concrete. Reinforcing the walls will give them more strength and stability as well as making them structurally sound.
For interior walls, it’s good practice in general to use 1/2” rebar spaced at a distance of every 8 feet along vertical lines and every 4 feet along horizontal lines (3). For exterior walls, use 1/4” rebar spaced at a distance of every 10 feet along vertical lines and every 6 feet along horizontal lines (1).
Place vertical framing at each end of the structure and vertical studs on either side of each window or door opening.
Place vertical framing at each end of the structure and vertical studs on either side of each window or door opening. The vertical framing and studs will provide the strength for the wall. Attach the tops of the studs to the 2x4s that run horizontally, making sure all posts are plumb and level. Cut poles to length if needed, placing them at an equal distance apart.
Once you have placed all necessary studs, add horizontal 2 x 4 boards to connect each pair of adjacent studs.

- Next, fill in the gaps at the corners by adding more 2 x 4s to form a box shape. Be sure that all boards are level and plumb before installing them.
Add two braces at each corner and one in the middle by fixing 2 x 4 cross bracing between two stakes that are parallel to each other and perpendicular to the wall being built.
The stakes should be laid out in a square, with each stake being perpendicular to the last. The cross-bracing should be nailed between the two parallel stakes and against each of the corners. Once you’ve finished laying down your stakes, you can measure for accuracy if needed. Make sure that all of your measurements are accurate by using a tape measure and marking off where each piece will go on top of one another before nailing anything in place so that there is no confusion later on when it comes time to build up your forms (which we will talk about next).
Concrete walls are stronger if they are reinforced with rebar or wire mesh.
To make a concrete wall more durable, you should use rebar or wire mesh. Rebar is a steel reinforcing bar that’s used to reinforce concrete. It can be placed in the bottom of the form or embedded into the wet concrete. A half-inch diameter rebar is recommended for most home projects, but check with your local building department because they may have different requirements. You may also want to consider using wire mesh if you need to build an extremely sturdy wall; this material helps prevent cracking and keeps the concrete from shifting while it dries.
Conclusion
Building concrete forms is a very simple process that requires only basic tools and a little bit of skill. You don’t need to be an expert or have any special equipment to build strong and stable concrete forms. Once you’ve built your first set of forms, it will become much easier as time goes on because the process becomes second nature. Keep reading this post for more details on how to make concrete forms
