Drainage

This floor drain will increase the cost and a lot of extra work is needed to be done to the foundation. For laying of pipe, excavation is required to be done to drain to a curb or drainage area.

For rainwater, gravel is much better. Through the gravel foundation, heavy water will easily run but it requires to run around concrete.

Additional work is to be done since grading is required to be done in order to divert water away and around a concrete just similar to the way in which water is diverted away from a house.

Concrete when gets wet will remain in that state for some amount of time and will dry as fast as that of gravel. Since water stays on concrete for some amount of time, it will rot the wood that touches the concrete. For gravel, this problem is not a big problem as the standing water easily drains away.

Splashing

As soon as water hits gravel a gravel foundation will diffuse it easily. The presence of rough, porous, and uneven surfaces on gravel, will prevent water and other liquids from splashing up and entering the wall.

Strength

For larger structures that will require more strength and support, it is previously mentioned concrete shed foundation will be a great choice for it. In addition to the floor, just concrete can be present there for many needs.

For tying the structure to the ground footing can also be installed along with anchors. After that, the grounding of the shed makes it a safer choice in case of a lightning storm.

Looks

The concrete flooring look is loved by many people. Many modern-styled homes are also giving it a required choice for their building.

They can be given the required color, polishing can be done, can be stamped, textured, or just left bare. This material is very versatile in nature and looks quite good in many home styles.

Pests

A seal attained on a shed built on a concrete foundation will be as tight as a house. This will make it very hard for pests to get into the shed from under the walls.

While for gravel this will not be the case. If a shed is being built right on top of a gravel foundation then there will be very little scope to stop the entrance of animals or bugs into it.

Stains & Drainage

Drainage problems and stains are the two problems that are associated with a concrete shed foundation.

Concrete will easily stain and it is very hard to clean. If work is being done inside the concrete shed then that will be very messy you should prefer gravel for that.

A well amount of drainage will not be available. In order to counteract the problem floor drains need to be installed. While this process is expensive and will require a considerable amount of excavation as well as a spot for draining into.

Cost

Should a Shed Foundation Be Bigger Than the Shed?

A same-sized concrete slab should be used by you as that of the shed if a concrete shed base is being used by you. Whereas a 12” wider gravel base should be made to use on all sides while you are using the gravel foundation for your space.

By providing a 12” lip on a gravel shed foundation will provide you with numerous benefits which are mentioned underneath:

The wood is protected from puddling or splashing water which helps in the prevention of rot. Soil will not be able to splash onto it so the shed will be kept cleaner.

Mowing will become easier as the grass and weeds will be kept away from the shed. By providing more gravels reduction in water runoff will be possible.

What Type of Gravel Is Used for a Shed Foundation?

If your choice is gravel then a rock is to be chosen by you. ¾ inch drainage rock or trap rock is the best choice of gravel for a shed base.

Enough compaction can be possibly done for making the base firm along with allowing drainage of water if the right sized gravel is chosen.

Instead of using just larger and smaller stones a combination of stones can be used by you. It will very importantly depend on the soil type and for how long you will use the shed.

In order to carry heavy loads type of stone which compacts well must be used. If more drainage is needed then you must use jagged stone that will settle more opened spaces. You must compact the gravel properly, no matter what type of stone is being used by you.
