A Caisson is a cylinder shaft fabricated from concrete and placed underneath a building tier that dives down into bedrock. Caisson structures are essential when constructing anything on top of high moisture soil or weak soils.
Caissons work great to improve the structures strength especially for buildings which are dated and can benefit from stabilization.
Caissons are commonly used in underwater construction for bridges and piers, where a solid concrete Caisson may be sunk into place.
Caissons are also used to prevent water seepage into soils, similar to a dam, which will prevent the structure from decreased support due to moisture. There are several different types of Caissons:
Creating a Caisson Modification
After Caissons are constructed above ground they are then driven into the soil or mud until a secure and durable soil or bedrock is reached.
