When To Choose A Concrete Foundation

There is one main scenario when you should choose a concrete foundation for your shed: When your shed or garage doesn’t have a pre-built floor.

If you shed or garage comes with a floor built in, then a gravel shed pad is your best choice. A gravel shed pad helps to keep the bottom of your shed dry and it reduces the amount of water that splashes up against the sides of the shed. It is the preferred foundation for sheds with wood floors. We have an entire article detailing the differences between gravel vs. concrete shed bases! 

If you purchase a shed without a floor, we’d be happy to install a concrete slab for you. Many larger prefab garages will also need concrete footers and concrete floors installed.

The process was very stress free and the crew that did the job was great. The 24’x30’ foundation was prepped, blocked and the concrete poured in one week. We could not be happier with the job. I don’t think we will be building my more sheds but if we do, we will use this company again.Read moreALV UjWWRW JnMf2lYdtPgCzh5IkvhLtRSJ 3FIIWsIpJA uqfyKfr4=w80 h80 pMark ReedSite Preparations LLC installed the concrete block foundation and concrete floor for my new garage and the breezeway that will connect the garage to my house.

We had a new concrete pad for a garage with 4' deep footers installed- and the work was so professional, and so meticulous that I was simply blown away by what ONE PERSON can do with the right tools, experience and organizational skills. I spent 18 years building towers for communications systems, I have worked with hundreds of contractors. This is at another level. It may sound too good to be true- but trust me, I had a true five star experience- and I could not be happier with the work. Frankly I wish other trades would pay attention and have a similar work ethic!!!!!Read moreALV UjV7qwZTTBfl kOnC yebCgCnBYxmwFk tk71Q9leS9KaTFaAMJ 5Q=w80 h80 pMark LalumiaJay and his team of Stephen and Jesus were excellent. My shed site was about 11 inches off level and they did a fantastic job with all aspects of the crushed stone foundation. Despite some pretty significant tree roots, stumps, and even some concrete that was found while digging, they did a phenomenal job and made sure everything was cleaned up when they left. I would absolutely use them again if I ever need this type of foundation built. Thanks fellas.Read moreALV UjXKMOd92wCrdX3 rB5z2p9J2k7Q7x BegIqEDwvS1dHNHw2uSY=w80 h80 pTerri BGideon and Josh did a great job on our 10x16 shed pad, which I purchased from Stolzfus Structures.

They were super courteous, did a great job and had it done in a couple of hours at a reasonable price. You couldn't pay me to drive a truck down those steep Pennsylvania hills on the Lincoln highway, I guess they I do it every day so it's no big deal for them. The thing is this is all they do, so don't ask them to do a driveway or other cement work if it's not a foundation for a shed or building. If I need one again I'll know who to call.Read moreALV UjXDD4mZZzfiQYRBfSD6REkuX7lwEiOkyEpgnsQjRGVdTrsjI7Oltw=w80 h80 pChuanting YouJohn and his team (Dave, Chris and Mike) did an excellent work building a concrete shed foundation for me for a reasonable price.Read moreACg8ocLH4Ef x59XBX45M2WLOtlRRZ4J0sLc6RqgRbCDjXS nqvizQ=w80 h80 pPhilip OlivieriSite Prep did an amazing job grading my property to setup the absolute best foundation for my new shed.

FAQs

The best type of concrete foundation depends on the type of project you’re looking to complete. There are several different concrete strengths, and the best one to use for your foundation will depend on what you’re looking to build.

The depth of a concrete foundation depends on a number of factors such as frost line considerations, soil type, the load the foundation will bear, and your local building regulations. Typically, the minimum depth of your concrete foundation should be 12” below the ground and below the frost line in colder climates. 

The lifespan of concrete foundations depends on soil conditions, foundation quality, maintenance, materials used, and other factors. Generally, most concrete foundations last 50 to 100 or more years as long as they’re well-constructed and properly maintained.

For an average size foundation of 16×24, the typical cost is $4,000. However, the exact cost will depend on your project’s size and scope. You can request a price sheet from us that includes different foundation sizes. 

Concrete foundations typically take 28 days to cure when the concrete reaches its highest strength. The curing process at minimum should last 7 days. 

A concrete slab foundation is a single layer of concrete that’s typically 4 to 6” thick while a concrete pier foundation consists of multiple columns spaced at intervals to support the structure’s weight. The main difference is that concrete slabs distribute weight evenly and concrete piers transfer the load across designated points. Also, slabs are better in areas with even soil distribution while piers are better suited for uneven terrain.
