What is the function of shed foundations? What are the benefits of the foundation of a shed? How deep should the foundation of a shed be? What happens if you select the wrong type of foundation?
How do shed foundations function?
Foundations function similarly by dispersing the weight of a shed over a greater area to ensure that they don’t overpower the bearing capacity of the soil that supports them. .
To put it in simple way, imagine that you are walking through the snow wearing your regular boots. With every step you take, you’ll sink into your knees (or more) according to what depth the snow gets.
But, when you are wearing snow boots, your weight is spread over a wider area and you are able to move more comfortably without getting into the snow so deeply. .
Shed foundations function similarly by dispersing the shed’s weight over an extensive area to ensure that the wood doesn’t sink into the ground. .
What are you expecting from a shed foundation?
Shed foundations don’t have the same stability as a foundation for a house. They don’t have to be as solid since it doesn’t matter as much if the shed shifts just a bit .
The foundations of houses are dug into the ground and are designed to limit movement to the minimal. This is due to a variety of reasons, including :
- The connections for drainage to the house could be affected by movements>
- Cracks in walls are more obvious and alarming
- The majority of houses have brittle interior surfaces, which means cracks are more obvious.
- The size of houses is greater than sheds, so when one component moves in a different way from another and cracks occurs. >
If a shed does shift and tilt towards one side due to reasons. It’s quite simple to straighten them and level them back up due to their small size and relatively lightweight. .
How deep should foundations for sheds be have to ?
As we have discussed previously, foundations for houses are designed to allow little movement, and therefore are dug fairly deep. Depending on where you live and the soil type under your home, a typical minimum house foundation is around 400mm .
The reason is that the underside of the foundation lies beneath the “frost zone”. When the soil gets cold and then freezes during the winter, the soil expands and may lift structures if the foundation’s underside is higher than this zone .
The frost zone is different based on the distance North you reside. The colder the region, the more extensive it is in the zone of frost. In the majority of places within the UK the foundations’ minimum depth for homes can be 600mm. . But, foundations for sheds, they don’t have to be at this level.
Since it doesn’t matter as much whether sheds shift (see the previous paragraph) shed foundations are quite shallow. Even if you reside in areas that are frost-prone .
The soil in an area will have a higher bearing capacity when you drill deeper, and is also more stable. .
