Costs To Install Concrete Slab

Concrete slab installation costs a minimum of $5.35 per square foot for a 4" thickness, and as high as $10.55 per sq. ft. for a 6" slab with thicker edges, styrofoam beneath the slab, and wire mesh. Adding radiant heat, extra dirt work, or grading to the sub-base costs extra. If you want to add additional reinforcement due to poor soil conditions, or if you're worried about big cracks, put some structural reinforcing metal in the concrete foundation with either wire mesh or rebar. Also, if your going to go with 4" thick slab, reinforcing metal is highly recommended to make your slab structurally sound. Costs To Install Concrete Slab Item Average Cost Per Square Foot 4" Slab Base Price $5.35 Increase to 6" Slab + $0.50 – $0.85 Thicker Edges (From 12" - 2') + $1.00 – $1.50 Vapor Barrier + $0.50 2" Styrofoam + $2.00 Wire Mesh + $0.35 Pump Truck (If Concrete Truck Can't Reach) + $900 flat Total Range $5.35 – $10.55

Labor Cost For Concrete Slab

The cost of labor to pour concrete is $45 per hour. There can also be a delivery fee of $60. To have concrete poured and finished, it will cost $2.52 to $2.60 per square foot for the labor, and $2.83 to $3.57 per square foot for the concrete itself. Concrete slabs are poured either off or on the job site. Smaller slabs, such as the hot tub base can easily be poured offsite and then delivered to your home. Larger slabs, such as a driveway, are poured onsite.

Cost To Pour Concrete Patio Slab

A concrete patio is generally 4” thick and costs $5.53–$10.25 per square foot to install. For a typical 12x12 patio slab costs ranges from $796 to $1,476. Always reinforce slabs that are 4” thick with rebar for strength. Your final cost may be affected by many design factors. [9]

A simple square or rectangular patio will be the most economical.

Curves, although attractive, cost more due to the mold that needs to be constructed. Walkways can add a nice aspect to a yard, especially if you have different kinds of flower beds. Site prep – The ground needs to be level, and any rocks or branches will need removing.

Concrete Slab Foundation Cost

Most homeowners spend between $5.40 to $6.40 per square foot for a 4” thick foundation, and $6.40 to $8.20 per square foot for a 6” reinforced slab on grade. A 1,600 square foot reinforced concrete slab foundation costs $11,680 on average. The cost includes “fine grading, slab base, forms, vapor barrier, wire mesh, 3,000 PSI concrete, finishing, and curing. For thickened edge slabs, add the area of the thickened edge. Use 500 square feet as the minimum job size.” [4]

Concrete Foundation Types

The three main types of concrete foundations are T-shaped, slab on grade, and frost protected. T-Shaped – Slab with footing below the frost line that’s poured after the walls are constructed. – Slab with footing below the frost line that’s poured after the walls are constructed. Slab on Grade – Slab poured over internal reinforcement of rebar and wire mesh. – Slab poured over internal reinforcement of rebar and wire mesh. Frost Protected – Slab poured over polystyrene insulation, with additional polystyrene insulation outside the foundation wall

Concrete Slab On Grade

Slab on grade refers to a concrete slab that's used as a foundation for a structure. The slab is created from a mold built into the ground that’s reinforced with rebar and wire mesh. The frame is constructed from wood, and the concrete and aggregate are poured into the mold to harden.

The three types of concrete slab on grade are: [3]

Slab on the ground – slab with concrete beams around the perimeter

– slab with concrete beams around the perimeter Stiffened raft slab – slab with concrete beams set in a grid throughout the slab – slab with concrete beams set in a grid throughout the slab Waffle raft slab – above ground slab poured over polystyrene “void forms.”

Concrete Slab Thickness

Most residential concrete slabs are between 4” and 6” inches thick with the minimum recommended being at least 4”. This thickness is recommended for walkways, driveways, patios, and garages. Commercial driveways can be 6” to 8” inches thick to bear up under traffic from heavier delivery vehicles. Check local building codes to find out how thick your concrete slab needs to be. Another factor impacting the thickness of the slab is the type of soil that is underneath. In prepping for the concrete, the soil must be tamped down well and covered with a layer of gravel or sand. A licensed concrete contractor will know how much gravel to lay and how to properly prep the soil. Concrete Slab Cost By Thickness Slab Size 4” Thick 6” Thick 20x20 $2,122 – $3,324 $2,732 – $4,128 30x20 $2,655 – $4,155 $3,415 – $5,160

Grades of Concrete

Concrete grades are based on the strength of the concrete after 28 days. Different grades of concrete are required for different uses. A residential grade is different from commercial grade, especially where a several story building is concerned. Numbers followed by the letter M indicates the different grades. The letter M refers to Mix, and the number relates to ratio amounts of cement, sand, and loose aggregate all mixed with water. Grades of Concrete Concrete Grade Uses M15–M25 For most residential uses. M15 is 1:5:10 (cement:sand:loose aggregate) M25–M45 For commercial uses. M25 is 1:1:2. M50–M70 For commercial uses requiring greater strength* *Everything over M25 is considered a design mix, and lab tests are necessary to determine those ratios. Ratios above M25 are used for extensive construction projects requiring high strength. [5]

Concrete Slab Cost Calculator

The average cost of concrete is $3.50–$5.50 per square foot for a 6” slab. The price can go up based on further requirements for the job. Factors that can influence prices are grading, base, forms, thickness, finishing, and concrete mix characteristics.

Wire Mesh For Concrete Slabs

If you need to add additional reinforcement to your slab, an excellent choice for smaller slabs is adding wire mesh. The typical cost of concrete installation includes the use of fiber mesh in your slab, but if you need wire mesh instead, add $0.35 cents per square foot.

Rebar For Concrete Slabs

To ensure your slab or foundation structurally sound, its highly recommended to add steel rebar, especially if you go with a 4” thickness. This thickness is particularly helpful if you have poor soil conditions, or want to prevent big cracks. Reduce the thickness of your slab from 6” to 4” and save $0.50 cents per sq. ft. per sq. ft. A vapor barrier underneath the slab will add $0.50 cents per sq. ft. per sq. ft. If your slab is in a hard-to-reach area and the concrete truck can’t reach it, you’ll need the services of a pump truck, adding approx. $900 to the cost estimate. to the cost estimate. Some slabs will require thicker edges, costing an additional $1–$2 per sq. ft. [7]

Pros and Cons of Concrete Slab Foundation

Pros

Less expensive than wooden floor joists and wood construction.

Fast – a floor can be poured in a day or less.

With no crawl space under the house to allow hot/cold air through the floors, utility bills are lower.

No problems with mold, mildew, rodents, or insects.

Cons

The lack of a crawl space means all furnace parts and ductwork must be installed above the floor. Plumbing is under the slab, and leaks are not always noticeable until you receive a very high water bill.

Concrete slabs can crack due to variations in moisture and the weather.

Concrete Slab Repair Costs

Concrete can crack and ruin the look of a patio or driveway. Depending on the size of the crack, it costs from $500 to $2,500 to repair one. Sometimes drainage will cause problems, and that moisture can be directed away from the concrete slab. Correcting drainage problems can cost $1,100 to $5,500. [16]

Concrete Slab Crack Repair

Concrete expands and contracts with the temperature. In hot weather, it can expand, and if it meets with an unmovable object, it will crack. The growth of tree roots underneath the concrete slab can cause cracks as they grow larger, pushing the dirt up under the concrete.

The settling of soil as time goes on can cause cracks.

Water can get under the slab and cause some erosion. Anything shifting under the concrete slab can cause cracking. Excessive weight on the concrete slab can crack it. Know how much weight a concrete slab can safely bear.
