Advantages and disadvantages
A classic solution with many benefits is to pour a slab over a strip foundation. Nevertheless, this kind of project necessitates large financial outlays. In an attempt to cut costs without compromising the strength and functionality of the foundation, builders started utilizing inverted, monolithic cup-shaped structures that are set on stiffeners.
- Increased strength. It provides reliable stability and immobility of load-bearing walls.
- Reduced consumption due to the absence of unnecessary material consumption.
- A wide range of tape options that allow you to find a high-quality solution for different conditions.
- Possibility of arranging a basement.
- Compatibility with different types of soil, including weak-bearing.
The benefits of a strip foundation also include quick turnaround times and simplicity of installation. However, the technology also has some serious drawbacks in addition to its advantages. Several challenges arise during the installation of engineering system units, necessitating the arrangement of extra space for their placement.
Installed directly under the slab, redundant water supply and sewer systems are used in the event that the primary water supply becomes clogged and can be utilized to solve the issue.
Construction technology of a house without a basement
In the "house without a basement" project, the strip foundation slabs rest entirely on the earth, adding to the building’s structural integrity. The process of pouring concrete mixture into a pit and then laying a heat insulator over it is used to build such a structure.
Building a strip foundation that is 40 cm wide and 40–70 cm deep is the first step. The type of soil and local climate have an impact on the precise depth values.
Every 40–50 centimeters, there must be multiple vertical ends of reinforcement, measuring 12–14 mm in thickness, along the entire length of the foundation if a reinforcement mesh is to be installed. Connecting the strip to the monolithic slab with reliability is their task.
The outside formwork is positioned 20–25 cm above the foundation. It will take one to two weeks for the foundation to harden before you can remove the formwork and make the necessary preparations for the slab. You must excavate a pit that is 50–60 cm deep using an excavator or hand tool. The depression’s bottom is leveled as much as feasible.
The next step is to add a layer of sand. It ranges in thickness from 15 to 20 cm. It’s crucial to use a vibrating plate to compact the sand mixture after pre-wetting it with water.
The sand is then covered with geotextile, which keeps the sand from combining with crushed stone while the foundation is being used. The geotextile extends 40–50 cm around the pit’s edge and is sewed together with specialized equipment.
These layers are covered with crushed stone. At least 20 centimeters should be its thickness. To eliminate voids and irregularities, the layer must first be leveled and tamped before being poured with cement milk.
After hardening, a waterproofing layer is applied to the formed pie. Sheets that block heat are then placed. Dense grade penoplex works better as a heat insulator.
The next step involves pouring the slab and laying a reinforced frame. The concrete mixture may take a month to crystallize. Following this period, you can start the most important task, which is installing the house.
Backfilling under the slab
On a strip foundation, a monolithic slab allows for homogenous backfilling. This could be sand from a river that doesn’t contain clay or other materials that hold water.
There are two types of backfill: sand alone or sand mixed with crushed stone. The latter technique results in a bottom layer with a higher compaction density because the sharp edges help to effectively compact the sand. Sand that is five centimeters thick is used to level the surface.
Formwork
Formwork assembly is a step in the process of pouring a slab on a strip foundation by hand. It is a wooden box set 10–15 cm above the sidewalk’s concrete surface. To avoid gaps, it’s critical to install the formwork as precisely as possible. Support bars and angled stops are used to secure the outer portion, preventing the panels from being forced out.
A deck is built before work begins if formwork is required for a slab with a base. In order to ensure high fixation reliability, a system of support beams, crossbars, and other reinforcing elements is installed.
The deck has a polyethylene film attached to it in order to seal the structure and prevent concrete mixture leaks.
Reinforcement
A wide range of materials must be ready in order to reinforce foundations built on monolithic slabs. Working rods are fixed up to 20 centimeters apart from one another. Two layers of reinforced lattice, spaced 10–15 cm apart, are required in total. Fixing the supports is required to ensure that the rods are monitored for proper geometry.
Do I need to insulate the floor
One practical and crucial step in resolving the issue of moisture buildup and concrete surface soaking is the insulation of the floor covering. On the other hand, because the entire coating will need to be insulated with a waterproof material, carrying out this task will cost a significant amount of money. It is a unique penoplex that has a 20 cm thickness.
Extruded polystyrene foam cannot be replaced with simple materials because they will not withstand large loads and will shrink too quickly, lowering the slab’s dependability.
Pouring the slab
The slab is poured consistently. It is imperative to set up a moveable tray for feeding concrete to avoid any issues. It can be applied in an even layer and connected to a mixer.
Encouraging equipment to approach from multiple directions is crucial for streamlining the concrete feeding process. The level of the uppermost layer of reinforcement bars needs to be considered when pouring.
The height of the concrete layer above the remainder of the structure should be 5 cm. Securing a system of drains is necessary to make pouring and related tasks easier.
Following the pouring process, a polyethylene sheet is put on top of the coating to offer dependable UV protection. Watering the concrete is essential in the early stages to keep it from cracking when the material’s humidity changes.
28 days are needed for the concrete mixture to solidify.
For any do-it-yourself home builder, pouring monolithic slabs for a strip foundation is an easy but essential task. We’ll walk you through every step of the procedure in this post, from preparing the site and erecting the formwork to mixing and pouring the concrete. Even without expert assistance, you can guarantee a strong and long-lasting foundation for your structure by adhering to these useful pointers and methods.
Technology for a house with a basement
The installation technology will differ if a house with a basement is built on a strip foundation on a monolithic slab. Although the project will require more work, the cost of the materials will go down.
First, builders are applying similar principles to the manufacturing of strip foundations. A deck, consisting of a single horizontal panel constructed of wooden boards, is mounted at the level of the upper border.
Bars with a cross section of 5×5 cm and a pitch of 0.7–0.8 m are chosen for the lower portion of the deck. Installing beams on the bars and fastening the purlins on top are necessary. The deck structure is opened up, and communication components are positioned. Installation of the hatch is still ongoing.
Polyethylene covering the entire area will help prevent dehydration and the development of cracks.
In accordance with the previously mentioned technology, the floor slab is additionally reinforced. The concrete solution is then poured, and vibration equipment is used to level the surface. Insulation is done in the base or during the installation process.
Building a strong foundation for your house is essential to its longevity and stability. It’s crucial to carefully follow the correct procedures when pouring monolithic slabs for a strip foundation. Making sure the site is ready, erecting the formwork, and properly mixing the concrete will guarantee a sturdy and long-lasting foundation.
Take your time leveling and compacting the soil, positioning the reinforcement correctly, and evenly pouring the concrete throughout the process. By taking these precautions, you can help avoid common problems that over time can weaken the structure, like settling and cracking. Recall that the secret to a solid building is a well-executed foundation.
In terms of financial savings and personal fulfillment, taking on this project on your own can be very satisfying. You can get results that are on par with professionals if you plan carefully and pay close attention to detail. Always put safety first, make use of the appropriate tools, and
