Choosing the right foundation type is extremely important to build a solid structure. The strip footings are one of the most commonly used types of foundations in the construction of houses, factories, and 2-story houses. The 2-story house's strip footings have a simple structure, easy construction and reasonable cost, suitable for many projects.
The 2-story house's strip footings are of interest to many people because this is a common house model commonly built in Vietnam. Let's learn about this model to get an overview.
A strip footing is a foundation located under pillars, columns, and walls to increase the load-bearing capacity of the project. They have the shape of long strips, long parallel rows or intersecting in a cross shape.
The 2-storey house's strip footing can be classified into the following types:
Independent strip footing: Each strip footing can only bear the load of one column or group of columns. Independent strip footings can be classified into 2 types:
Continuous strip footing: The strip footings are connected into a long strip, bearing the load of the entire project. Continuous strip footings can be classified into two types:
The structure of a 2-story house's strip footing has many great advantages such as:
Designing a 2-story house’s strip footing is an important work before starting construction. It is necessary to calculate which type of strip foundation is most suitable. Some important information below you need to note.
Strip foundations have a simple structure and construction costs are not too high. Therefore, it is often suitable for projects with average loads. For projects with large loads, pile footings should be given priority.
Strip footings are often suitable for projects in the form of townhouses, villas or garden villas... In addition, it is also suitable for other small-sized projects.
Two-story house strip footings are often commonly built in residential projects in Vietnam. This type is considered to have low cost because of its simple and quick construction process.
Calculating the size of the strip footing will help you understand the cost of materials. From there, there are more proactive plans for construction.
Minimum foundation width = 1/2 column width
Maximum foundation width = 1/2 column length
Minimum foundation width = 1/2 column width
Maximum foundation width = 1/2 column length
Commonly used materials for foundations today are concrete, steel, brick, stone... Depending on the size, load, and foundation soil properties, the number of materials used will vary. Therefore, you can contact BMB Steel if you want to learn more details.
After consulting the information about the overview and size of the strip foundation, understanding the process, experience and risks that may be encountered during construction will help the contractors be more proactive in their project.
The strip footing construction process goes through the following basic steps:
First, when constructing a strip footing, you need to clear the site. In this step, it is necessary to clean and tidy the premises. Determine the location to drive piles or dig foundation holes using specialized tools.
After clearing the site cleanly and neatly, it is necessary to dig foundation holes according to the previously marked locations. In this step, you need to strictly follow the drawing, do not dig too shallow or too deep. Normally the depth of the foundation only ranges from 2 to 2.5m and the width is 1.5m.
Next, depending on the type of soft or good soil, add a layer of reinforced sand. Make sure the hole has a neat, flat foundation for ease of the next construction steps.
In this step, we need to pour a concrete lining layer at the pit foundation with a height of 10cm. The purpose is to create a flat surface for the bottom and limit the loss of water from the upper concrete layer during the foundation pouring process.
This is an extremely important step and needs to comply with the pre-calculated design from the beginning. In particular, it is necessary to comply with the correct spacing between steel layers and between steel layers. At the same time, it is necessary to position the steel carefully so that the moving process does not cause the steel to move.
Next, it is necessary to assemble the foundation formwork. This step also needs to be careful to avoid unnecessary mistakes that will cause the concrete pouring process to not be as effective as desired.
Pouring concrete for the foundation is an extremely important step when building a cement foundation. The concrete pouring process needs to be carried out according to the design in the drawing. At the same time, the pouring process needs to be even and continuous.
Note that when pouring concrete for strip foundations, you need to pour from far to near, absolutely do not stand on formwork, distorting their structure.
After pouring the concrete foundation, you need to avoid physical collisions to avoid cracking or breaking. In addition, it is also necessary to ensure that the concrete is always moist by spreading a tarpaulin and continuously watering it for the first 7 days.
To construct strip footings with optimal efficiency, contractors need to grasp the following notes:
Strip footings are known as a popular type of foundation widely used in construction. The design and construction of strip footings need to be carefully calculated before proceeding. However, if this work cannot be guaranteed when building the foundation, you may face several risks such as:
Currently, the need to build houses, offices... is increasing. Therefore, there are many units providing strip footing construction services. However, to ensure the quality of the strip footings as well as construction costs, the contractor wants to find a reputable unit.
One of the units most trusted by business owners, contractors, and homeowners today is BMB STEEL. This is a company specializing in the design and construction of large tonnage factories. Therefore, they can construct strip footings for houses and offices extremely well and bring optimal efficiency.
Currently, BMB STEEL is being selected by Cheng Loong Co., Ltd. as a construction partner with 4 main items. Which includes BM2 powder-making plant, grinding room, main power plant, packaging workshop. The project has a total area of up to 63,000 m2 and uses nearly 1,500 tons of steel.
This is a project with extremely large loads, so the foundation design and construction stage are extremely important. However, with a team of professional engineers, all problems will be handled quickly and optimally by BMB STEEL. Therefore, if you need to design a strip footing or any pre-engineered steel construction project, you can immediately contact BMB STEEL for quick support.

During the construction of strip footings, many problems can occur if not carefully calculated. Therefore, you will need to refer to quick and thorough solutions.
The reason this situation occurs is due to not carefully studying the ground or generating loads that exceed the originally designed level. If you want to fix it, you must reinforce the house's foundation by expanding the bottom of the foundation.
This means we need to fabricate additional support structures under the old foundation. The simplest way is to add a reinforced concrete slab under the old foundation. Thus, the ice foundation will be firmly reinforced and can withstand greater force.
During the construction of the strip foundation, if standards are not followed, it can lead to cracked and collapsed strip footings. The cause may be due to a change in ground structure. However, it is mostly due to:
When cracks and corks appear, they can put your project in danger during use. Fixing this problem is also quite complicated. We need to have a realistic observation to see what level of subsidence and collapse is at, what is the cause, to have timely remedial measures:
It can be said that repairing and overcoming strip footing errors is extremely complicated. Not only is it unsightly and time-consuming, but it also costs a lot of money.
To avoid these situations from the beginning, you should find reputable construction units. These units often have a team of professional workers who design accurate drawings. The materials provided are of good quality and have a warranty after construction. Thus, the new project can be sustainable and stable with a long lifespan even after a long period of use.
