Underpinning is the process of strengthening the foundation of an existing building or other structure. The decision of underpinning requirement can be made based on observations. When an already existing structures start to show certain change through settlement or any kind of distress, it is necessary to establish vertical level readings as well as at the offset level, on a timely basis. The time period depends upon the how severe is the settlement.
Before the excavation for a new project, professionals have to closely examine and determine the soil capability to resist the structure that is coming over it. Based on that report the need for underpinning is decided. Sometimes such test would avoid underpinning to be done after the whole structure is constructed.
Benefits of Underpinning:
- Underpinning your foundation opens the hidden mechanics of the home and makes them accessible for inspection, correction and improvement
- As underpinning is usually undertaken in older buildings, there is old plumbing, electrical and insulation systems that can be replaced or upgraded with modern technologies. All these can be brought up to Building Code and to contemporary standards.
- Changes will have to be made to the waterproofing systems along with the underpinning so the life of the useable, dry space is prolonged.
- Long-term savings in energy costs
- Improved foundation strength
