Basic costs:

Grading: Before any work begins, you’ll need to make sure the area where you plan to pour your concrete is level and ready for work. That means grading the area. The necessity of this step varies depending on your worksite and the size of your project, but if it is necessary to level things out you can expect to be charged about $45/hour to get it done.

Laying A Foundation: Any large concrete project is going to require you to put down a base to pour the concrete onto. Usually this means laying a gravel base before the pour. Expect gravel to run about $12 per cubic yard delivered to the work site.

Labor: Unless you’re a sucker for back pain and sore muscles, and have a handful of very dedicated friends, you’re going to have to pay someone to build the forms, work the pour, and perform the finishing work. Typical labor costs will run in the neighborhood of $1 per square foot

Reinforcement: In order to ensure the longevity of your new concrete project, you’ll need to install some reinforcement after the forms are built to prevent cracking and other damage later on when your concrete expands and contracts with the weather. Wire mesh, plastic mesh, and steel re-bar are all commonly used materials that cost about 10 cents per square foot. Your contractor will be able to advise you as to what is the best material for your particular project

Concrete: Concrete prices will make up the bulk of your cost for any large concrete project. A good ballpark figure is $70 per cubic yard of concrete (But as stated in a previous blog, concrete can vary from state to state, even within a state. Here $70 seems really low for a cost, probably because the site was updated sometime ago. but the prices ranged from $86 dollars a cubic yard up to $150 a cubic yard) Check with manufactures in the area of your site location to acurately estimate costs.

 Spray coating:

The benefits of concrete construction are shared by spray-applied concrete, including strength, impact and fire resistance, insect and rot protection, longevity, and durability. A characteristic of sprayed concrete is low permeability. Also, spray-applied concrete allows the application of concrete in difficult locations that may be impossible using conventional formed poured-in-place methods.

Spray-applied concrete requires less formwork than poured-in-place (or no formwork if applied against a suitable excavated surface), thereby lowering material costs and form set-up time. Forms do not need to withstand the great pressures that develop with poured concrete. Savings in forms may be offset by higher labor and equipment costs

Pre Cast Concrete:

Priced in the $55 – $65 range per linear foot of wall, precast systems are competitive with other foundation walls, particularly when costs are examined as an assembly that includes footings and sub-slab drainage. Precast walls can be installed quickly in any weather. Because the concrete is cured in the factory, precast foundations can be backfilled as soon as the slab is placed and first floor bracing is in place, enhancing jobsite safety and site accessibility. Door and window openings, steel beam pockets, and brick ledges must be cast into the panels, so orders must be customized. The wall sub-base must be compacted and leveled, similar to precision required of footings. Use of precast panels should be submitted for approval by the building official at time of building permit application.

Foundation walls are relatively maintenance free. Regular maintenance of eave gutters and grade and plantings around foundation to assure that water is not ponding adjacent to the wall is required of any foundation system.
Installers should be experienced with assembling prefabricated foundation panels. In fact, some companies only allow certified installers to deliver and erect their systems. Once panels are erected, sealed, and bolted together, the basement slab can be poured. Floor joists above the foundation are conventionally installed and provide some of the bracing for the foundation walls. Once braced by the slab and floor system, backfilling against the walls can take place.
