    Concrete mix would be what is used when pouring a foundation. PSI will be the main concern you have on a foundation application as the weight of what is being built on top of that foundation will determine what PSI mix you will need as well as how deep or thick the foundation needs to be. Contact your contractor or engineer for their recommendation for those answers.

    Exterior expansion joints are added every 8 to10 feet in all directions. This will be the maximum area one should go before adding a joint. Interior joints are normally added every 18 to 20 ft in all directions. Expansion joints are critical when doing concrete work and greatly reduces concrete cracking. Concrete will create its own expansion joint in the form of a crack if these guidelines aren’t followed. Other ways to help prevent cracks in concrete is to be sure the mix is not to wet. Whereas wetter concrete is easier to mix it will most certainly create cracks when the water leaves the mix during the curing period. Dryer mix is better.

    Most professionals would call their local concrete company and get their concrete premixed and delivered. It makes it much easier and is pretty price competitive compared to that many bags of sakrete

    Thank you admiral001 for your post. There are many jobs that will justify a pre-mix concrete truck but there are just as many jobs that can and are being done with bagged material with superior results. Many of those jobs are even large jobs being poured in areas that the large pre-mix trucks can’t get to. We post these video's to assist those individuals who wish or need to do their own concrete projects

    Your example is 4' x 4'. How big can I reasonably go with your technique and materials? I would like to add 8' more length to a 24' wide slab. Is that in the realm of a do-it-yourselfer like me?

    First thing is we would ask about your comfort level with working with concrete. If you do not have any experience working with this type of material we would urge you to seek professional help for your project. The area you are describing will require around 50 - 55 bags of material...That is a lot of mixing and pouring even for a professional. We do not mean to discourage you from trying this project but would encourage you to call our 866-Sakrete number where a trained tech can help evaluate your project and answer any questions you might have and also offer you some assistance and suggestions.
