What Is Monolithic Slab?
The word monolithic meaning is used to concrete the whole structure at a time. In this article, we will discuss the importance of using a monolithic slab foundation for a high-rise building.
Smooth surfaces, proper alignment, and good quality work can be provided using modular formwork in monolithic formate. The use of modular formwork results in faster construction than the conventional method.
Monolithic foundation work is effectively suitable for durable structures and good quality. To build a monolithic structure we need formwork for construction.
Slabs, walls, stairs and door and window openings, etc. in a monolithic system are specially designed to be operated in one place. Monolithic slab foundation systems require less labour and the equipment can be used easily.
The monolithic slab system uses a modular formwork made of aluminium formwork. The system consists of a concrete wall and a reinforced concrete slab to transfer the gravitational load.
A monolithic slab foundation is the only pouring process in a single monolithic pour. In which the concrete floor is made with thick sections under the structural members above the base and on both sides of the perimeter. Its monolithic concrete pour construction is easy and maintains production costs.
Monolithic slab foundations are smooth and suitable for flat soils. In its process concrete is monolithically poured all at once. Therefore, monolithic slab for garage floor slabs is fast and cost-effective.
Only a single monolithic concrete is poured into the structure of the monolithic foundation. In which monolithic footing is made with dense sections in the part with load-bearing structural members and under the perimeter of the sides of the building.
For monolithic footing, the load-bearing wall part of the building is usually 12 to 18 inches thick and the non-load-bearing wall part is 4 to 6 inches thick for the slab. The main reinforcement and distribution reinforcement is made of a monolithic foundation by increasing the strength of the concrete by suitable wire.
It helps to keep the price cheaper than other types of foundation. Because this type of monolithic powder slab is poured together. The construction of monolithic foundations is a very simple and time-saving method
Monolithic Slab Foundation
Since the monolithic pour foundation is built in a single pour, the concrete slab is made 12 inches in the area under the load-bearing walls and 4 inches in all other areas. And a separate space is created to replace the flowers. This way the labour cost is reduced and quality is maintained as monolithic concrete pour has to be done together.
The monolithic slab foundation would last almost 50 years if constructed correctly. Because of the lack of complex components, there is nothing wrong with the slab itself.
This method especially plays a part in climate. Where the temperature is very low and the soil is not dry the benefits factor.
For this, the soil should be levelled and the soil should be well compacted. If there is debris in the soil, the space should be cleaned.
Application of Monolithic Slab
- This type of foundation has a flat bottom
- These concrete foundation types can save labour costs.
- This concrete foundation type can save time and reduce costs
- This type of foundation can be done fast and profit can also be made This type of foundation can be a quality, proper line.
Procedure of Monolithic Foundation
Step:1 Prepare Soil
The soil beneath the slab needs to be properly compacted and verified that it does not contain any organic matter. The soil should be well compacted and levelled.
Giving slope to the ground is an important factor. It is important to calculate the flow of water and then proper management should be done.
Step:2 Trench Height
In a monolithic concrete slab, it is important to keep in mind that the thickness of the slab should be 12 inches where the load-bearing walls are located. The thickness of the monolithic slab is kept to 4 inches.
The part that enters the frosting and the trench needs a depth of 2 feet in those areas to prevent frost.
Step:3 Placing of Reinforcement
Monolithic slabs use 16 mm, 12 mm, and 8 mm diameter bars for wall reinforcement. Bars are used as required to carry the load. In addition, additional reinforcement is used to open doors and windows. A cover block is provided to maintain the distance from the bar.
Formwork for monolithic slab construction should be easily removable and reusable. This is called true formwork. Shuttering of formwork is done by a skilled carpenter.
The formwork should be as strong as the concrete pour.
A grade of M- 25 should be used in a monolithic pour foundation and coarse aggregate should be used as 20 mm in it. The cover block is kept from 25 mm thick to 50 mm thick.
Monolithic slabs of walls and wall slabs are opened to the wall formwork after 12 hours Slab – Central support is kept after 36 hours of slab concrete. After three days all supports are removed and further construction activity is carried out on the slab.
It should be cured for seven days. Water is sprinkled for curing. Curing plays an important role in affecting strength. Development and durability of concrete placing. The final stage is considered. Concrete should meet the required amount of moisture.
Advantages of Monolithic Slab
There are many benefits to single-base work. We will understand the following
1. Fast Work
A significant advantage of a monolithic slab is that it can be laid much faster than other foundations. Because it has to be poured all at once, this foundation can be poured down faster than other common methods, including stem walls.
2. Most Efficiency
We know that time is money in almost every industry. Given the ease with which concreting is done simultaneously in this method, this makes the construction project more affordable and faster.
Suitable for monolithic slab for garage. Its use is usually the most cost-effective method for making a garage floor. In this, from the very beginning, labour costs are reduced, saving on some of the financial amount required for a large house building project.
3. The Strength of the Need Can Be Obtained
Under the quality of this monolithic slab is possible to make it as tough as any other type of foundation. A single level is also obtained from this type of foundation.
4. Low Maintenance
A conventional system requires periodic regular maintenance of a pier and beam while you do not need to take special care for a monolithic pour foundation. A mono slab foundation can save you money in a long time.
Disadvantage of Monolithic Slab
- The convention foundation can give you space to put plumbing, electrical panels, and wiring.The monolithic slab foundation does not have crawl space. To solve this you need to leave space for electrical panels and wiring before the foundation.
- When a monolithic slab foundation cracks for any reason, its repairing cost is expensive.
- Your home stands just 6 inches or so above the ground on a monolithic slab foundation. Monolithic foundations are not effective in flood-prone areas. Some parts of the country are troubled by the flood situation.
Monolithic construction technology is used especially in the construction of monolithic foundations for high-rise buildings and skyscrapers. Monolithic construction resists high loads without destruction in the elevated seismic zone. And gives safety to the entire building.
The use of aluminium formwork in monolithic construction systems improves the quality of residential and commercial buildings. It is a disaster-resistant and cost-effective construction in modern times. Its methodology is fast and reduces large project costs.
