How to make a recessed strip foundation with your own hands: step-by-step instructions

Although it may seem difficult, you can build a recessed strip foundation for your house or garden structure on your own with the correct instructions. This kind of foundation, which is frequently utilized for larger buildings, entails digging a trench into which concrete is poured to create a sturdy base. It’s an essential component of building that guarantees longevity and stability.

You will need to gather some basic supplies and tools, like shovels, concrete mix, rebar, and a level, before you begin. To decide on the size and design of your foundation, you’ll also need to plan ahead. A successful build requires careful planning, so give your site a thorough measurement and marking out process.

Excavating the trench is the first step in building a recessed strip foundation. This entails excavating to the proper depth, which varies based on the building’s weight and the type of soil. After your trench is prepared, the next step is to install the formwork and insert the reinforcing rebar. These actions give the foundation more strength and form.

It’s time to mix and pour the concrete after your formwork and rebar are in place. To guarantee that the concrete is dispersed uniformly and is free of air pockets, this step of the process needs to be done precisely. You will need to keep the concrete moist as it sets in order to avoid cracks. Ultimately, you can take down the formwork and backfill the trench once the concrete has dried.

Although creating a recessed strip foundation on your own is a complex procedure, you can build a solid and dependable foundation for your building project by following these detailed instructions. If you are patient and pay close attention to details, you will produce results that are polished and long-lasting.

Advantages of a recessed strip foundation

The benefits of a recessed strip foundation influence the customer’s decision in a positive way.

1. Popular technology time-tested.
2. Allows to lay the foundation for the construction of powerful buildings.
3. Ease of execution.
4. Does not react to deformation.
5. Strong construction.
6. The construction is used for basements, garages. Concrete fills are walls in this case.
7. Durability.

Precast concrete lasts 80 years, brick foundations 35 years, and monolithic (buried, strip, reinforced foundations) 200 years.

When it is used

The depth of a strip foundation can vary. Lightweight constructions and one-story buildings require shallow foundations.

It is employed when building heavy materials, a house with a basement, or both.

For rocky rocks, heaving soil, and coarse-grained soil, it is essential.

Building a sturdy base for your structure while saving money and achieving a satisfying project can be achieved by doing your own recessed strip foundation. You will be guided through every step of the process, from organizing and trench excavation to pouring concrete and completing the foundation, with this comprehensive guide. Even individuals who are unfamiliar with do-it-yourself construction can confidently construct a sturdy and dependable foundation with the right guidance and advice. This guide will help to make the task of building a shed, garage, or small house easy and manageable.

Deepening requirements

In order to ascertain the tape’s height, consider the following factors:

• soil composition;
• distance to groundwater;
• soil freezing depth is taken from SNiP;
• total mass of the house;
• relief of the site for the foundation.

It will be unclear what the average freezing depth is in Russia’s various regions. Middle zone: 1.5, south: 1, and north: 2 meters.

Because of this, the tape’s height ranges from 1.3 to 2.3 meters. There is a 30-cm reserve when the tape is laid.

Preparatory stage

Clear the area of trash and the growing layer to prepare the area. It is essential to bring supplies, equipment, and an inventory.

Draw a mark in the desired location.

Marking of the site

Apply every aspect of the building site on paper. You will require the assistance of a theodolite in order to convert dimensions to the surface of the earth.

Place loop-shaped pegs at the corners where partitions and load-bearing walls meet. Extend a rope or cable. Verify the squareness of the corners, indicate the formwork’s width, and account for the panel thickness.

The closest building is three meters away, and there are five roads.

The trench’s laid size has been expanded by 1.1 meters. to lay a cushion there that will ease pressure should the earth heave.

Calculation of the depth of the foundation

The depth of the strip foundation is not inexpensive. As a result, an exact computation is performed.

Here are some prerequisites that must be met:

• the mass of the house with furniture, people, facing material;
• each region has its own soil resistance. The data is taken from the table.

The following formula is used when the data is gathered: the computed load is divided by the soil resistance. Consequently, we obtain the area of the foundation’s base, which we will refer to as S base.

Next, we multiply the soil’s bearing capacity by the foundation’s area to obtain (S base).

The larger of the two values should be the comparison value. In the event that a fractional number is received, the strip foundation base value is rounded up.

At that point, the upper load—the house—will be perfectly supported.

Necessary tool

You will need a concrete mixer to quickly fill formwork with concrete.

Theodolite device, level.

Material (metal or wood) for the formwork.

Shovels with various functions, such as a bayonet or scoop.

Nails, saw, and trowel.

A device that vibrates to eliminate bubbles.

For marking the perimeter, use rope or cable.

Reinforcement needed to build the framework.

Wire or a welding machine to tie the frame together.

Step	Description
1. Plan and Design	Determine the foundation size and depth. Check local building codes and soil conditions.
2. Excavate the Trench	Dig a trench to the required depth and width, ensuring it"s level and straight.
3. Build the Formwork	Construct wooden forms to shape the concrete and hold it in place.
4. Install Reinforcement	Place steel rebar in the trench for added strength, keeping it off the ground.
5. Pour the Concrete	Mix and pour concrete into the formwork, filling the trench completely.
6. Cure the Concrete	Keep the concrete moist for several days to ensure proper curing.
7. Remove Formwork	Once the concrete is fully cured, carefully remove the wooden forms.

It can be difficult but rewarding to build a recessed strip foundation on your own. It can save you money and give you a sense of accomplishment. You can make sure that the foundation of your structure is sturdy and dependable by adhering to these detailed instructions.

Careful planning, accurate measurements, and meticulous site preparation are the essential steps. The construction of formwork, rebar reinforcement, and excavation are essential for guaranteeing the longevity and steadiness of your foundation. By taking the time to complete each step accurately, problems can be avoided later on.

A crucial step in the procedure is pouring the concrete. To prevent any weak spots, make sure the concrete is mixed to the proper consistency and poured evenly. For the concrete to reach its maximum strength after it has set, proper curing is necessary. Correct curing of the concrete can be achieved by covering it and keeping it moist.

Recall that your greatest assets for this project are perseverance and meticulousness. You can lay a solid foundation for your building that will last for many years by devoting time and energy to it. Your DIY recessed strip foundation project will be successful if you take your time and carefully follow the instructions. Don’t rush through the steps.
