Monolithic Definition. 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 ...
Does a monolithic slab need footings?
A footing is placed below the frost line. Blocks are laid in place to form a wall once the footing has cured. After constructing the walls, a slab floor is poured between them and on top of the footing. Monolithic: This foundation is created by pouring a single layer of concrete to form a slab and footing.

What is the difference between a slab and a monolithic slab?
So, a monolithic slab is a giant block of cement that's poured in one, fell swoop. While it may be poured all at once, it's not necessarily a uniform slab. It's made to be thicker in areas where there will be a load-bearing wall and in all perimeter areas (in place of footers).
What is a monolithic floor?
Merriam-Webster defines monolithic as “cast as a single piece” and “formed or composed of material without joints or seams.” Here's how other flooring-focused professionals think of the term monolithic: Carpet and tile professionals—Monolithic is a type of pattern for modular carpet tile and hard-surface tiles.
What is the strongest foundation for a house?
Foundations are mostly constructed from strong material so they can hold the house in place even during earthquakes and cyclones. Therefore, they are generally made up of concrete which is the strongest construction material.
Do monolithic slabs crack?
They tend to crack along the thickened perimeter when significant weight loads are used, like block exterior walls.
How deep is a monolithic slab?
A monolithic slab has a thickness of just 12 inches (1 foot) to 18 inches. These are base structures constructed with a single concrete pour, usually containing a 4-inch thick concrete slab with thickened internal sections beneath load-bearing walls and always thickened at the edges of the perimeter.

Does a concrete slab need footings?
A concrete slab foundation needs footings in order to: Provide support to the walls of the building built on the foundation. Resist heaving and shifting due to freeze/thaw cycles. Prevent water runoff from undermining the slab.
What does monolithic mean in construction?
all in one pourMonolithic means “all in one pour” so the foundation is constructed in one single pour that is made up of a concrete slab with thicker areas under load bearing walls and all perimeter edges to take the place of footers. Because this Slab is poured all at once, it is much faster and keeps labor costs low.
What is difference between floating and monolithic slab?
Floating slabs are sometimes called monolithic slabs because they have no contact with the foundation. In some construction floating slab is used as support and only after the foundation has been constructed that we throw the floating slab. Usually monolithic slab is less expensive than Floating slabs.
What are the three types of foundation?
Foundation types vary, but likely your house or home's addition does or will have one of these three foundations: full or daylight basement, crawlspace, or concrete slab-on-grade.
How can you tell what kind of foundation you have?
One of the best ways to find out is to check if there is a crawl space beneath your home. While concrete slab foundation rests directly on the ground, the other types of foundations will have space between the ground and floor joists.
How do I know my foundation type?
The topography, geology, and pedology (the study of soil) on your construction site in addition to the size of your building and other factors, like the type of construction, will determine the type of foundation that is appropriate for your building.
How do I know what foundation to build?
General factors to be considered for determining depth of foundation are:Load applied from structure to the foundation.Bearing capacity of soil.Depth of water level below the ground surface.Types of soil and depth of layers in case of layered soil.Depth of adjacent foundation.
How do you find the foundation of a building?
Check the foundation walls by sighting down from one end. Look for areas that bulge or lean which can indicate uneven load on the foundation. Both the foundation walls and home walls should be flush and level. Also look for any potential water damage or cracks in concrete.
What is monolithic footing?
Monolithic Footing: A monolithic foundation provides only one pour, such that the foundation is built to replace the footers with a sole pour made of a concrete floor with thicker sections under structural members and both sides of the circumference.
What is a monolithic slab foundation?
Monolithic Slab Foundation: To aid with the load-bearing of walls, the concrete slab that is poured is smoother on the outside, and there are no footers on the outside. For flat ground, monolithic slab foundations are ideally suited.
How deep should a monolithic slab be?
The thickened edge of a monolithic slab is formed by a trench along the circumference of the slab. The trench can only need to be a foot deep and a foot wide in warm climates. The trench will need to be as deep as 2 feet in areas that get penetrating frosts and may be insulated to stop frost heaving under the slab. #3.
What are the advantages of monolithic slabs?
Among the benefits of monolithic slabs are: 1 Faster average building time. 2 Higher price. 3 Very strong, particularly with the addition of reinforcement of steel and fiber-mesh. 4 It can be further improved by the addition of post-tensioning on weak soil lots.
What is monolithic construction?
Monolithic construction is a process where, using a homogeneous mixture, a building is monolithically constructed. It is a structure formed from a sole material, assembled as well as excavated. Both walls, slabs, stairs, along with door and window openings, are cast in place in the Monolithic Method. The on-site process by using specially made, ...
Why is monolithic construction important?
The monolithic construction is important for minimizing the thickness of the wall, minim izing the width of the base , and minimizing the seismic impact.
How thick is a monolithic foundation?
Building monolithic foundations is truly easy. It is possible to do each of these in one day. A monolithic structure has a thickness of just 12 inches. Through suitable reinforcement, this is the base for value, rate, and design of preference. It is also the greatest to express, too.
What is monolithic slab?
Monolithic slab. Stem wall. Monolithic Slab Foundation. Monolithic literally means ‘single pour,’ which highlights the key point of difference with this type of foundation – it’s poured all in one go. The fact that it is poured in one go makes it a quicker process, which helps to keep labor costs low. The concrete slab that is poured is thicker on ...
How long does a slab foundation last?
Despite the simplicity, a monolithic slab foundation will last around 50 years if properly constructed. Because of the absence of complex elements, there’s little to go wrong with the slab itself.
Why are slabs poured in one go?
The fact that they are poured in one go means that they are efficient to make, and they also provide a solid foundation. The absence of seams and cold joints (plus the addition of some steel reinforcements) gives monolithic slab foundations a rigidity and stability that makes them extremely strong.
How far is a concrete slab foundation from the ground?
With concrete slab foundations, your home is only raised 6 inches or so from the ground, meaning that the rest of your house is susceptible to flooding. In some parts of the country, this is a major weakness.
Is a monolithic slab foundation energy efficient?
ENERGY EFFICIENT. Monolithic slab foundations don’t have a space between the ground and the home, meaning that you don’t have to waste as much energy in your home heating the air below it. With a basement or crawl space, energy is being constantly wasted.
Do you need to do upkeep on a monolithic slab?
Unlike a pier and beam system, which requires fairly regular maintenance, a monolithic slab doesn’t require you to do any upkeep. As long as you give it an inspection at regular intervals to ensure there aren’t cracks in the foundation, there’s nothing you need to do on a month-by-month basis to keep it in good shape.
Can a monolithic slab foundation be flat?
Monolithic slab foundations are best suited to flat ground. If the ground is not flat, then a lot of fill dirt is used to level off the ground; in time, this can lead to problems with cracking if the ground is not properly compacted. With a stem wall foundation, the concrete is poured in multiple stages.
What is a Footer, and Why Do You Need One?
A footer (or a footing) is a large piece of concrete- sometimes reinforced with iron rebar- that is poured around the outside perimeter of a home. Once it’s completely set, the foundation is built on top of that footer.
What Happens When a Typical Slab Foundation Settles?
Settling is our industry’s term for sinking into the ground. As we covered at the beginning, all homes settle. The problems begin when a home settles unevenly. Maybe the ground is eroded along one side of the house, or the soil density isn’t consistent across the entire property.
How Are Repairs Different for a Monolithic Slab Foundation?
To summarize: when we repair settling in a typical slab foundation, we have to determine first if you need piers to raise the outside of the foundation OR if you need the inside foundation slabjacked.

What is monolithic slab?
What is a Monolithic Slab? A monolithic slab is a concrete foundation that is completed in one pour. In my design, the concrete is 12” thick around the perimeter to support the load-bearing walls with a 4” thick slab in the middle. Traditional foundations, often referred to as stem-wall, typically take 3 pours – the footing, ...
Why is monolithic slab not a good option?
Here are some of the reasons that people shy away from monolithic slabs: If your ground is not even, a monolithic slab is not a great option. Too much concrete is required to compensate for the slope of the ground. If your home needs to be built high off the ground due to being in a flood zone, a monolithic slab doesn’t allow for this elevation. ...
How many pours does a foundation take?
Traditional foundations, often referred to as stem-wall, typically take 3 pours – the footing, foundation walls and then slab. Monolithic slabs combine those all into one piece, and act as part of the structure of the house. For those nerdy building science guys and gals (like me), here is a detailed diagram of my foundation:
Why can't I use a monolithic slab?
They can not be used when a lot of fill dirt is required because the concrete is more likely to crack if the ground isn’t compacted well enough.
What type of foundation is used for a new home?
There are two types of foundations predominantly used during the construction of a new home; Stem-Walls and Monolithic slabs. Both carry specific benefits and challenges during construction and it is important to know these before breaking ground during a new home building project.
Can monoslabs be used as stem wall slabs?
When used under the right conditions, Monoslabs can be just as sound as Stem-Wall slabs. In most sub division community builds, the ground is level throughout the entire property and more densely compacted with very little fill dirt required.
What is monolithic foundation?
Monolithic means “all in one pour” so the foundation is constructed in one single pour that is made up of a concrete slab with thicker areas under load bearing walls and all perimeter edges to take the place of footers. Because this Slab is poured all at once, it is much faster and keeps labor costs low.
Why can't you use monolithic slab?
Monolithic Slab cannot be used when more fill dirt is needed because the concrete is more likely to crack if the ground is not compacted sufficiently. This is a problem for homes that need to be built to rise above the flood plane provided by civil engineers (as most buildings in Florida should).
Why is a floating slab costing more?
The cost of a Floating Slab is higher because there is a lot of excavation, concrete, and labor required for the construction of strip footing and the frost wall. Floating Slab is the best option for construction of sheds but for construction of house there are some disadvantages to think about. When Floating Slabs are constructed in ...
Why is a floating slab called a floating slab?
Floating Slab are called “ floating ” because they are allowed to move over the ice line as a monolithic unit. Insulation can also be added to reduce movement due to frost, depending on the needs of the project. Building a floating slab is one of the most economical ways to build a foundation. Traditional foundations include a strip footing on ...
What is a floating slab?
Floating slabs are used as the basis of the foundation for a variety of civil structures like sheds, car garages, additions, cottages, drive sheds, accessory buildings, and barns. In Floating Slab, the Slabs have a perimeter of thickened reinforced but no frost footings. Floating Slab are called “ floating ” because they are allowed to move ...
What is mono pour?
Mono pour which means the way it is built and poured, rather than the kind of the foundation of a building. If there is a large structure or unstable soil, you definitely want a deep foundation, but with a basic garage in good soil, a floating slab is good and attractive.
Is a floating slab monolithic or monolithic?
In some construction floating slab is used as support and only after the foundation has been constructed that we throw the floating slab. Usually monolithic slab is less expensive than Floating slabs. Floating slabs also happens to be a monolithic slab-shaped as an upside-down U, where concrete is to be applied monolithically or in 2/3 steps.
