Underpinning provides support to deep foundations with different types of piles. This process allows your foundation reach deeper or to distribute its weight across a bigger area.
Underpinning Methods and Uses
There are a few reasons that a current building may require underpinning. Generally used when the soil is poor, underpinning usually includes micro piles or helical piles that reach into the ground until the weight or load is better supported. These piles can be anywhere from 15 to 150 feet into the ground. They can be the attached to structure to provide primary support, or provide added, lateral support with beams.
Additions and Changes
Old foundations might not be able to withstand damage from shifting soil which can make the foundation sink, crack, or break. If a building’s capacity has radically changed, the foundation cannot support the additional load. Underpinning provides support to the foundation by moving the added weight from the surface soil to micro piles or helical piles that are bolstered by soil that is deeper underneath the surface.
Underpinning is a successful repair technique designed to bolster foundation when the existing weight or a new addition becomes too much for your foundation. When the building’s weight changes, the current foundation can’t stand against the added pressure. Before you build, consider that building onto your current space may influence how your foundation will be able to withstand the structure.
Soil and Water
Foundation failure can also come when the soil is too wet or too dry. Soil expands when the dirt is saturated with water and shrinks when the water dries out. This pressure can cause the soil to heave and sink. In turn, this will either put a lot of pressure against or take support away from your foundation.
