What Is a Slab?
Slabs are structural elements manufactured from concrete constructed to produce flat surfaces, usually horizontal, in building floors, roofs, and bridges.
The slab is usually several inches hefty & is additionally supported by walls, concrete beams are usually cast monolithically with the slab, by steel beams, by columns, or anchored by the bottom.
If reinforcement is required, slabs could also be pre-stressed or the concrete will be spilled over rebar positioned within the framework.
Types of Slabs
19 Different types of slabs in construction are as follows.
1. Flat Slab
A flat slab doesn’t possess beams, & is supported by concrete columns or caps itself, & hence it is additionally known as a beam-less slab. Loads are directly conveyed to columns. The flat slab is effortless to develop & requires smaller formwork.
The thickness of the Flat Slab = is 8″ or 0.2 m.
Where Flat Slabs are Used?

- The auto sprinkler is less complicated.
- Less construction time is required.
- It surges the shear strength of the slab.
- It helps to diminish the instant within the slab by diminishing the clear or effective time span.
Disadvantages of Flat Slab
- Utilized during a flat plate system, it’s impossible to possess a sizeable span.
- Not suitable to hold up fragile partitions.
- Higher slab bulkiness.
2. Conventional Slab
These square-shaped slabs which are held up on beams & columns are termed traditional slabs. The soupiness of this slab is bijou but the depth of the beam is sizeable & load is conveyed from beams to columns. It requires greater formwork when with respect to the flat slab.
Main Reinforcement Bars– Horizontal
Distribution bars– Vertical
Based on the length and breadth it’s categorized into 2 types:
- One-way: Supported by beams on opposite sides, carrying a load in one direction.
- Longer Span / Short Span ≥
- Two-way: Supported by beams on four sides, carrying the load in both directions.
-
- Longer Span / Short Span =< 2
The thickness of the Conventional Slab: 4″ or 10” & Length- 4m.

Disadvantages of Conventional Slab
Conventional concrete slabs are limited in length and thickness. They require a specific level of thickness to maintain their strength – usually at least 4 inches for a slab-on-grade foundation. Long concrete slabs elevated above the ground are limited in length due to the danger of cracking.
3. Hollow Core Ribbed Slab or Hollow Core Slab
Hollowcore ribbed slabs gain their name from the longitudinal voids or barren cores which run through the modules.
The cores can act as service ducts & can conveniently diminish the self-weight of the slabs, bumping up the structural efficiency. The cores have satisfaction in sustainability terms diminishing the amount of concrete utilized.
Width: 1200 mm
Depth: 110mm to 400 mm.
Where Hollow Core Ribbed Slab are Used?
Using a hollow-core ribbed slab not only reduces building costs it also reduces the overall weight of the structure.

- The casting forms or molds required for precast modules are very expensive & hence only economical when large-scale production of indistinguishable units is desired.
- Construction requires strict supervision and skilled workers.
6. Dome Slab
This is developed in Temples, Mosques, Palaces, etc. Domes are in a semi-circle shape and shuttering is done on a conventional slab in a dome shape and concrete is filled in shuttering forming dome shapes. This is one of the types of concrete slabs.
Thickness- 0.15m.
Where Dome Slabs Used?
One major benefit of the dome-shaped system is the ability to provide structural carrying capacities equivalent to conventional slabs but requires less concrete to do so (up to a 20% reduction in concrete consumption).
Advantages of Dome Slab
Domes are extremely durable and strong. While the average building life is measured in decades, the Monolithic Dome can be measured in centuries. They are fire, water, and wind-resistant, making them impervious to hurricanes, tornadoes, fires, and other threatening natural disasters.
Disadvantages of Dome Slab
- Unsustainable Materials. The three materials used in monolithic domes are not the most environmental products.
- Vulnerability of the Air Form. The airform is a delicate membrane that can easily become damaged by falling trees.

- Permits and Property Value. Building a monolithic dome may require special permits depending on the type of structure.
7. Pitch Roof Slab
A Pitch roof is a particularly lightweight inclined slab, generally developed on resorts for a natural look. A pitched roof is a roof that slopes downwards, typically in two parts at an angle from a central ridge, but sometimes in one part, from one edge to another.
The ‘pitch‘ of a roof is its vertical rise divided by its horizontal span and is a measure of its steepness
Thickness: 2″-8″.
Where Pitch Roof Slab are Used?
Pitched roofs allow natural ventilation between the outer layer and the building, preserving energy
Advantages of Pitched Roof Slab

9. Post Tension Slab
Post–tensioned (PT) slabs are typically flat slabs, band beams, slabs, or ribbed slabs. Post–tensioned slabs use high-strength tensioned steel strands to compress the slabs, keeping the majority of the concrete in compression.
The slab, tensioned after developing a slab is referred to as Post tension slab. Reinforcement is provided to check the compression force.
Where Post Tension Slab are Used?
Post–tensioning, which is a form of prestressing, has several advantages over standard reinforcing steel (rebars): It reduces or eliminates shrinkage cracking-therefore no joints, or fewer joints, are needed. Cracks that do form are held tightly together. It allows slabs and other structural members to be thinner.
Advantages of Post-Tension Slab
- It gives permission for slabs to be skinnier.
- It allows the creation of slabs on soft soils.
- Cracks are packed tightly.
- Post-tension slabs are eximious ways to construct stronger structures at a reasonable price.

- The thickness of the projected slab is greater than that of the typical RCC two-way slab.
14. Grounds Slab
Ground slabs are those slabs that are poured directly into excavated trenches in the ground. They rely entirely on the existing ground for support. The ground (more correctly known in the industry as the foundation) must be strong enough to support the concrete slab.
Where Ground Slabs are Used?
Ground-bearing slabs, also known as “on-ground” or “slab-on-grade”, are commonly used for ground floors on domestic and some commercial applications. It is an economical and quick construction method for sites that have non-reactive soil and little slope.
Advantages of Ground Slab
Concrete slab foundations are more common in states with warm climates where the ground is less likely to freeze and cause the foundation to crack. There are good reasons for building or buying a house on a slab, such as cost savings and less risk of damage in certain instances.
Disadvantages of Ground Slab
There are good reasons for building or buying a house on a slab, such as cost savings and less risk of damage in certain instances. The disadvantages include that heating and cooling units may have to be installed on the ground floor, which takes up living space. There is also a potential for cracks.
15. Sunken Slab
sunken slabs are slabs that are cast at a certain depth (200 or 300 mm or any other depending on design) below normal floor level. This extra depth is used for placing pipes and utility ducts.
Where Sunken Slab Used?
This type of slab is used in bathrooms, toilets, washing places, or water closets. The purpose of providing a sunk slab is to prevent water from spilling over from the sunk slab area towards the surrounding slabs.

- Decrease the height of the slab.
- Slabs, waterproofing, and brickbat take more time to construct as compared to Sunken Slabs.
16. Ribbed Slab
Ribbed slabs are made up of wide band beams running between columns with narrow ribs spanning the orthogonal direction. Normally the ribs and the beams are the same depth. A thin topping slab completes the system. Waffle slabs tend to be deeper than the equivalent ribbed slab.
Where Ribbed Slabs Are Used?
Ribbed provide a lighter and stiffer slab than an equivalent flat slab, reducing the extent of foundations. They provide a very good form of construction where slab vibration is an issue, such as in laboratories and hospitals
Advantages of Ribbed Slab
- In this type of slab, the tension stress is eliminated on the tension side of the slab. The strength of concrete in tension is very small and so the elimination of much of the tension concrete is done by the use of pan forms.
- Economical where the live loads are fairly small such as apartment houses, and hotels.
- Long slab spans can be constructed through ribbed and waffle Slabs. In many cases, long spans are desirable in the building. Ribbed or waffle slabs.
- Provide architectural advantages. All the Electrical appliances can be installed easily in the gap of the ribs which can be architecturally aesthetic.
Disadvantages of Ribbed Slab
- Not suitable where the live loads are huge as heavy manufacturing buildings, or warehouses.
