Building your own formwork for a blind area can be a satisfying do-it-yourself project if you’re taking on a home improvement project and need to take care of the surrounding area. Formwork serves as a solid barrier that keeps water away from your foundation and stops erosion by shaping concrete like a mold.
Formwork construction for a blind area isn’t as difficult as it might seem. A few simple supplies and tools will allow you to build a form that is both strong and protective of the foundation of your house. From material selection to formwork assembly, this guide will lead you through each step so you can produce a neat and polished end product.
Regardless of your level of experience doing do-it-yourself work, this project is a fantastic way to increase the longevity of your house while cutting costs. Let’s get started and see how you can approach this task effectively and efficiently.
| Step | Description |
| 1. Planning | Measure the area around the house where the blind area will be installed and decide on the dimensions. |
| 2. Materials | Gather necessary materials such as boards, nails, stakes, and concrete mix. |
| 3. Marking | Mark the outline of the blind area with stakes and string to ensure straight edges. |
| 4. Excavation | Dig a trench along the marked lines, ensuring it is level and at the required depth. |
| 5. Formwork Assembly | Assemble the formwork by attaching boards to the stakes along the trench edges. |
| 6. Reinforcement | Place a layer of gravel in the trench for drainage and add rebar if needed for extra strength. |
| 7. Concrete Pouring | Pour concrete into the formwork, level it, and smooth the surface with a trowel. |
| 8. Curing | Allow the concrete to cure properly, keeping it moist to prevent cracks. |
| 9. Removal | Once the concrete has cured, carefully remove the formwork. |
| 10. Finishing | Backfill around the edges and clean up the area to complete the project. |

Purpose of the blind area
The width and height of the rear panel are taken into consideration when creating the formwork. The back wall needs to be installed as soon as the construction is finished.
The blind area is a waterproof covering that slopes away from the building and encircles the entire building’s perimeter. Preventing soil erosion around the house and shielding the foundation from precipitation, snowmelt, and roof-flowing water are the primary objectives. The building’s overall service life is greatly increased by using the element.
Furthermore, the blind area’s surface serves a decorative purpose, giving any building—even ones made of concrete—a polished appearance. Additionally, this will make the transition throughout the building incredibly convenient.
Regardless of the kind of foundation that is used during construction, waterproofing is required. It should be done as soon as the work is finished, rather than being put off for a long time. It is necessary to perform shrinkage regardless of the kind of foundation.
Sizing
Building codes state that, depending on the soil’s quality, the blind area’s width should range from 0.7 to 2 meters. One meter or so should be the recommended width for soils with average standard values. The width ought to be 20–30 cm greater than the overhanging roof.
To find it for a particular house, follow these steps:
- Attach a plumb line to the edge of the roof (in a convenient place).
- Drive the hammer into the peg where the weight touches the ground.
- Measure the distance from the peg to the wall of the building.
- Add 20-30 cm to this value and get the width you need.
As an illustration, let’s say the roof angle is 90 cm. We then add 30 cm to get a 120 cm strip width.
Preparatory stage
Preparation is the first step in doing formwork for a blind area around the house on your own. The marking procedure is straightforward: drive a peg into each corner of the house, then extend a string between them so that the distance from the base to the point where the blind area begins (in our case, 120 cm) equals the width of the entire perimeter of the blind area.
A few more steps must be taken before you start installing the formwork:
- In accordance with the markings, using a shovel, dig the ground to a depth of about 25-30 cm (which corresponds to the length of the bayonet of a standard construction shovel).
- Carefully remove the roots of all plants so that future shoots do not damage the strength of the structure.
- Fill the bottom of the resulting trench with a layer of sand 10-15 cm thick.
- Level the sand and moisten it with water.
- Compact the sand with a vibrator or hand tamper (this operation should be repeated 2-3 times, periodically wetting the sand).
- Now you can start formwork.
Formwork installation
Concrete foundation formwork establishes the concrete’s geometry and stops the solution from spreading.
There is no need for specific expertise to handle the formwork for the blind area with your hands:
- Drive wooden pegs-rods vertically from the outside of the twine at a distance of 1.5-2 m from each other.
- We lay the boards on edge along the perimeter (we fasten them to the studs with self-tapping screws).
- Using screws and pieces of the same board about 40 cm long, connect the boards from the outside (an overlap of about 20 cm on each side).
- Place the upper ends of the formwork boards flush with the height of the set.
- Place the boards around the perimeter of the building in relation to the edge.
It is simple to determine how many boards are needed because an inch board, which is 2.5 cm thick, has a standard length of 6 meters. Using the measurements you took, determine the perimeter of the sidewalk’s length. To determine the number of complete boards, divide the result by 6. In order to connect every board, add one more board as well (this is sufficient because it is unlikely that there will be more than 15 connections).
Building your own formwork for a blind area around your home is a useful and satisfying project that improves the appearance and usability of your house. You don’t need to hire pricey contractors to accomplish professional-looking results if you have the correct supplies and equipment and put in some preparation and work. You can approach this project with confidence and create a long-lasting, well-constructed blind area that shields the foundation of your house from water damage by being aware of the fundamental procedures and concepts involved.
A meticulous approach is essential at every stage of the procedure. Make careful to measure precisely, to properly fasten the formwork, and to mix the concrete. These actions will assist you in avoiding typical pitfalls and are essential to the project’s success. A sturdy and long-lasting blind area can also be achieved by properly compacting and leveling the soil before pouring the concrete.
You’ll save money and feel accomplished as well as gain useful skills by adhering to these recommendations. When you finish a formwork project by yourself, it can be a very fulfilling experience and a demonstration of your ability to upkeep and modify your house. Never forget that meticulous planning and precise execution are essential for success. You can build a high-quality blind area that will benefit your house for many years to come with perseverance and dedication.
Making your own formwork for a blind area around your home can be a fun do-it-yourself project that improves the aesthetics and security of your house. This tutorial will lead you through every step of the process, from material selection to formwork construction and installation, guaranteeing that you can accomplish expert results at a reasonable cost. Whether your goal is to prevent water damage, enhance drainage, or simply give your house a more polished appearance, anyone can confidently take on this task thanks to the simple approach.
