Concrete Slab Foundation Cost & Installation Process

A concrete slab foundation is a large, heavy lair, or slab of concrete that is ordinarily 4-6 inches wide in the innermost and cascades directly on the ground all at one time. However, the concrete slab is commonly located on a slab of sand to develop drainage quality and to act as a buffer. A concrete slab does not have a channel beneath a building. This type of foundation differs from house foundations, quality of land condition, and basement requirements. The soil must be qualified because if it’s not, the foundation could sink or settle due to poor soil compilation.

Concrete Slab Foundation Cost?

Dependable concrete slabs are used for almost every foundation project, indoor or outdoor. The average concrete slab foundation cost is $3,600 to $7,200, with a national average of $5,400.

Typical Range: $3,600 to $7,200

National Average: $5,400

Types of Concrete Slab Foundation

The concrete slab foundation is a crucial structural element and is used to provide flat surfaces like floors and ceilings in buildings. However, there are different concrete slab foundation types which are depending on the span, length, and strength of a building.

There are mainly 3 types of Concrete Slab foundation in building constructional work. Such as:

T- Shaped
Slab on grade foundation
Frost Protected

The cost factors of surveillance cameras include indoor versus outdoor placement, resolution, field of view, motion detection, night vision, monitored services, remote viewing, connectivity, video storage, the number of cameras, and other features.

Prepare formwork

The formwork is the frame for the concrete slab. For measurements, consult the approved building plans to ensure the formwork is setup correctly. Following the process of laying the formwork correctly, reduces the likelihood that the concrete slab is compromised. Preparation of formwork must also follow established building standards and guidelines.
Excavate earth

The site is cut to near level with excavation machinery. Once the excavation is complete, the surveyor sets pins in the ground to mark out floor area and give tradesmen points to measure from. Electricians and Plumbers trench and run access for services. Footings and piers are dug to the Engineers specifications and the site is made level using laser level. Formwork is constructed around the perimeter of the slab to be poured. This will form the shape of the slab and hold the concrete while it sets hard.
Prepare slab bedding

It is important to prepare the slab bedding correctly. This will ensure that the concrete slab rests on a firm base and that the concrete slab does not start cracking. To prepare the slab bedding, use road base or crusher dust of a reasonable thickness based on building codes. Ensure that the surface is level and flat and compacted firmly. A well-drained base and compacted bed prevents the concrete slab cracking.
Install reinforcement

Reinforcement prevents the concrete from cracking, buckling and caving in when a load is placed on it by improving the tensile strength of the concrete and making it more durable. Ensure the reinforcement bars, spacers and ties are installed in accordance with the approved building plans.
Pour, compact and finish concrete

A professional should be engaged to pour the concrete from a reputable pre-mix company. This will ensure that the concrete is at the specified strength. Prior to pouring, soak the slab bed with water to prevent moisture loss. Once the concrete is poured, add control joints where required. As the concrete dries, it will shrink. To avoid cracks forming randomly, control / expansion joints ensure cracks to not develop.
Cure concrete and remove formwork

Curing a concrete slab involves the application of water over an approximate 7 day period. Applying moisture to the concrete helps it to seal. Spraying twice daily is ideal – use light mist sprays with complete coverage. After 24 hours of the concrete being poured, the formwork can be removed. Take care removing the formwork to avoid any damage to the concrete slab. The slab can be walked on after 3 days, but avoid heavy loads for at least 7 days

Concrete vs. Cement Slab

They’re commonly mistaken as the same material, but cement is actually the dry binder that makes up part of the concrete material. While cement could be used on its own to create a cement slab, it’s not advised. Cement slabs are prone to cracking and breaking since they don’t undergo the same curing process that concrete slabs do. The cost of a cement slab is $1 to $5 per square foot.

Concrete is made of a mixture of water, cement, and aggregate material like gravel or sand.
