It's easy to work with, lasts virtually forever, is environmentally friendly, and most of all a gravel foundation will provide exceptional support for your shed. More importantly, most of today's shed manufacturers recommend you build a gravel shed foundation before they deliver your shed to you.
Here are three very important reasons why you should plan on building a gravel pad for your new shed:. One of the reasons a gravel foundation is one of the most popular choices for garden sheds is that it allows you to spread the weight of your shed and everything it in over the surface of the entire foundation.
Other forms of shed how to put up a shed base such as concrete piers focus all of the weight on smaller areas putting more stress on the framework of your shed, increasing the risk of significant damage. Even if your backyard is not level or has a small amount of slope to it, a gravel pad gives you the opportunity to create a solid level base upon which to place your shed.
By using a wood frame, you can overcome a reasonable amount of slope. Concrete piers, wood frame foundations, even concrete slabs can raise the floor height of your shed more than you want. Trust me, there is nothing worse than trying to get a lawn mower or other heavy items in and out of a shed that is sitting too high. A gravel shed foundation lets you control the height of your shed and can even let you put your shed at ground level or at least only slightly above it.
The next major decision is do you build retaining walls to hold the gravel in place or do you go crazy and make your foundation free form? As we go through the rest of the process, I will go over the benefits of both forms of a pad. Each has their own unique features and benefits.
Some of this decision is based on the space you have to work with, the type of gravel you plan to use, and the quality of the ground in your backyard. Let's face it, to most of us, gravel is nothing more than how to put up a shed base bunch of crushed up rocks.
And while to a certain extent this might be true, there is more to gravel than meets the eye. Gravel comes in a wide range of types and grades, each of which has their uses. There are two main categories of gravel:. There is little difference between these two types of gravel are minor, but for a gravel shed foundation, the 21A variety is the better choice.
This material helps to fill in the gaps between the larger gravel pieces making it a more stable foundation that will not settle once your shed is placed on it. Although these grades of gravel can be similar in size to 21A and 21B, they do not contain any fine materials to help fill in the gaps.
This means there is nothing to help hold the gravel in place leaving it to shift around rather than settle into a firm foundation. On top of this, once you place your shed on the foundation, the gravel can still move around, allowing your shed to sink into the ground. This can also cause your shed to become unlevel, which can cause damage to the structure. Image courtesy thecoverguy. If you decide to build a retaining frame around your gravel shed foundation rather than go with a free-form foundation, it is important you use the right type of lumber for the structure.
The temptation might be to use standard lumber such as 2x6s to save money, but this is a bad choice. You may also be tempted to use creosote coated lumber such as old railroad ties. As long as you have no intention of growing edible vegetables or fruit within 50 feet of your foundation, this might be okay. The problem with this is that creosote contains a range of toxic chemicals that are known to be hazardous to your health. The reality is that you really shouldn't use this type of lumber anywhere near your garden.
Standard lumber is not strong enough, nor will it as I found out the hard way last very long once you bury it in the ground. The best choice for building the framework around your gravel shed foundation is pressure treated lumber such as 4x4s or 6x6s.
Not only will they provide you with a much stronger framework, being pressure treated will help ensure they last for many years without rotting and allowing the gravel to spread out, letting your shed down gradually.
If you plan to build a framework out of timbers, they must be anchored in place before you pour the gravel into your form. If you plan to use a single layer of timbers, you can use lengths of rebar to secure them in place. However, if you need to use more than one layer of timbers, you should use galvanized spikes. These are available in a variety of lengths to meet your needs at your how many pounds are in a stone hardware superstore.
Be sure to buy spikes that are long enough to go through the number of boards you plan to use and then at least 12 inches into the ground to ensure the timbers stay in place. Just like any other major project you plan to undertake in your garden, there are a certain number of tools needed to build a gravel shed foundation. Among these are:. Now that I have gone over the basics regarding the materials you are likely to need, the next step is to go over building your gravel shed foundation one step at a time, starting with building a retaining wall.
In order to determine how much timber it will take to build the retaining wall, you need to know the overall size of your shed and then add three feet to both the width and the length. This will provide you with enough room for your shed and an extended footer around it to help keep water from getting in it. Start by marking one corner of your shed with a stake and then mark the other three with stakes. Be sure you have added the required extra space.
One way to be sure the stakes are set at the right spots is to measure diagonally between pairs of corners. Much like an equilateral triangle, these measurements should be the same.
Using level find the lowest corner of the ground you plan to use and cut a trench into the ground that goes all the way around the perimeter of your shed. Bear in mind your timbers should be inside the lines created by the stakes you have driven into the ground.
Be sure you use the level to ensure the trench is perfectly level all the way around. Start out by laying your first layer of timbers in the trench. Next drill several holes through each board and secure them to the ground using rebar or galvanized spikes. Wherever necessary, add in extra timbers offsetting each corner in much the same manner used in the construction of a log home.
This will help to keep the timbers in place. Now secure the timbers together using galvanized spikes spaced out every two to three feet driven into the timber below. Now comes the fun part, you have a hole in the ground inside the timbers for your gravel shed foundation, the only problem is that it is still full of dirt.

Finally, it's time to add in the gravel. Be sure you are using 21A or at least 21B gravel. Pour in no more than a 4-inch layer and then use the vibrating compactor to compact the gravel firmly in place.
This ensures it won't continue to settle once you have your shed in place. The screed will help reduce the high spots in your gravel by moving the excess gravel into the low spots, filling them in. Continue doing this until the layer of gravel is level with or slightly below the top of your timbers.
You have just finished building your first gravel shed foundation. Now all you need to do is install your shed and fill it with everything that goes with it.
The only time you should consider building a free-form foundation for your shed is if the ground you plan to put it on is perfectly flat. If you try to use this type of foundation on sloping ground, there is the distinct possibility that the ground under your foundation will erode out from underneath it. No matter whether you plan to build your free-form foundation on flat ground or a slope, be sure the gravel pad you create is approximately 18 inches bigger on all four sides than your shed.
Doing this will allow for a certain amount of corrosion to occur without affecting the stability of your shed.

If the shed sits directly on the ground it will begin to rot within a couple of years. Even pressure treated lumber rots. Moisture from the soil, insects, even rodents, can have a devastating effect on wood. Keep in mind that rain and snowmelt can pool around your shed making access wet and mucky. Snow buildup can make entry difficult too. If you want your shed to sit level, then a foundation is a common method to create a level base.

Concrete shed foundation blocks are a great way to create a level base for your shed. They can be doubled up to give a wide base, or stacked to build piers for higher clearance or uneven slopes.
Concrete blocks are ideal for flat or on-grade foundation support. Concrete blocks are a cast cement and an aggregate of sand and gravel. They are often referred to as concrete masonry units CMU.
The blocks usually have one or two hollow cores, but are available with solid cores — which are much heavier! The blocks come in different dimensions, making them a flexible foundation solution. Concrete blocks are not cinder blocks. They are made from a denser material than cinder blocks which have industrial ash as an aggregate. A key difference between is the susceptibility of cinder blocks to winter freeze-thaw. If exposed to moisture and freeze-thaw cycles, cinder blocks can begin to disintegrate.
If using cinder blocks protect them with the shed base, or regularly treated with a water sealant. Poured concrete reinforced with steel has more lateral strength than concrete blocks. Block and poured concrete need the same ground preparation for leveling and drainage.
You should have concrete blocks at every corner. Remember to support the middle area of the shed in a similar pattern. The spacing of the blocks is also affected by the framing material used to support the structure. I had a buddy who figured he was only going to store bikes and yard tools in his shed.
BIG mistake! Plan for today, build for tomorrow. There are many benefits to using concrete blocks for the foundations instead of other materials. Concrete blocks are readily available and pre-made.
Once the ground is prepared, they make a great on-grade raised foundation for your shed. The blocks are easy to move around and have a wide flat surface which eases the leveling of your shed platform.
Stack the blocks on uneven ground will provide a level surface. Double up the blocks, or double stack them, to provide more structural support. Concrete blocks come in different sizes for more foundation solutions too. If using hollow core blocks, fill the core with concrete and rebar to create a very solid pier or support.

There are basically 6 soil types. Soils are usually found in combination with each other but occasionally can cover a large area. Your soil type can impact the type of footing you will require, and if you can build where you want. The soil type and lay of the land, or its contours, affects how rain and snowmelt leave your property.
It should be considered when selecting your foundation site for your shed. It will also impact on the type of foundation you build. If it drains slowly but is the only spot you can build, then you may want your shed higher off the ground. The slope of your ground also affects drainage and foundation type. Build on a slope and you may have more to excavate at one edge and need different levels of concrete blocks. There are some other things to keep in mind when planning your construction project?
