UNIFORM SUPPORT

The key for the soil support system is uniform support rather than strong support. Sure, it has to be able to support the slab, and on most ground that's not a big problem, at least across the middle of the slab, since the load is spread across so much area.

HOW CAN WE IMPROVE THE SUBGRADE?

Most subgrade improvement is accomplished by compacting the soil. In extreme situations, when the soil is particularly bad or the loads high, soil stabilization can be used. In this process, portland cement, calcium chloride, or lime are mixed into the soil then it is compacted.

COMPACTION EQUIPMENT

There are two ways to compact the soil or subgrade—static force or vibratory force. Static force is simply the weight of the machine. Vibratory force uses some sort of mechanism to vibrate the soil, which reduces the friction between the soil particles, allowing them to squeeze together more easily.

PLACING THE CONCRETE
