Another shortcut for constructing a concrete spread footing is using a bell auger. One of the cheapest and least laborious options is a pier foundation. The weight of your container and everything in it is pushing down on the ground due to gravity. As long as you have the center of the plates in approximately the right place, if your measurements are off by an inch or two, the container will still be on the steel plate with a clear line of force through the foundation.

They work through a combination of both the bearing capacity of the screws helixes and skin friction of the screws shaft. Will this be OK or do I need to pump concrete grout between the bottom beams of the container to carry more of the container load to the sub-grade? A few examples of screw pile manufacturers are Heli-pile, Helical Anchors Inc., and Techno Metal Post. In the same way, when you put bearing pressure on the ground, the force spreads through the ground in a cone or pyramid shape thats typically assumed to be about 60 degrees wide. For the average homebuyer or DIY builder, you mainly need to know that settlement does exist. To elaborate, most pier foundations are constructed by boring a cylindrical hole in the soil with an auger, then placing concrete in the hole (usually with reinforcing steel embedded).

The ground beneath us may seem simple and static, but it can be uneven, unstable, and difficult to predict. The loads are combined using equations based on different civil engineering theories including Strength Design, Allowable Stress Design (ASD), and Load and Resistance Factor Design (LRFD). How to Use Concrete Tie Down Blocks for Sea Containers Typically, an empty 6-meter shipping container weighs between 1,800-2,200 kg, and an empty 12-meter shipping container weighs around 3,800 to 4,200 kg, depending on its type.
