Underpinning the Foundations

Underpinning the Foundations

Depending on where your properties are situated, the land it is built on might not be able to support its weight. That is why the majority of homes in the United States are constructed with a foundation. Your foundation is the only thing protecting your building from sinking underground. Although it is ideal that it can hold your structures for a very long time, it can encounter various types of structural damage.

After getting hit by disasters consecutively, more specifically floods and minor quakes, the composition of your foundations will weaken. If it is not addressed immediately, chances are that your property will be inconvenienced from the ground up. Busted basements, crawl spaces, and unlevelled flooring are just some of the problems you will encounter, and repairing them is not only difficult, but expensive, as well.

One great method to reinforce your foundations is to have it underpinned, which we, at Foundation Rescue Team, gladly provide.

Types of Underpinning Methods

Underpinning is necessary if both your foundation and the soil surrounding it have experienced a change in structure, composition, usage, and the like. Depending on what our experts are facing, they will choose any one of these methods:

Mass Concrete Underpinning

Also known as the "traditional underpinning," this process strengthens your current structure by digging boxes underneath your properties, and pouring concrete strategically. It is usually applies when your existing foundation is at a shallow depth. However, this method also works well even at fifteen meters deep. There is no need for heavy machinery, and its simplicity makes it low on cost.

Mini-Piled Underpinning

This method is best used if the conditions follow:

  • Ground is Very Variable
  • Restrictive Access
  • Significant Environmental Pollution
  • Minimal Structural Movements

This is generally used when the loads from foundations need to be transferred to a stable ground. To do this, however, structural engineers need to use heavy equipment that is specifically designed to work through these conditions.

Beam and Base Underpinning

This method is more advanced than the mass concrete underpinning, because a reinforced concrete beam is constructed above, below, or as a replacement for, the existing footing. The design of this method is dependent on the structure of your property and its load.

Mini-Piled Underpinning Schemes

This method includes a pile and beam, cantilever pile-caps, and piled raft systems. Each item has a specific role to play.

  • Cantilever pile caps: to avoid disturbing the inside of your property
  • Pile and Beam: supports the walls
  • Piled raft: used when an entire structure needs to be pinned

Resin Injection

This relatively new method uses a mixture of structural resin and hardener. Once injected into the foundation ground beneath the footing, it will expand due to a chemical reaction, and fill in any crevice and/or opening that weaken the structure. Constant injection may rise or be re-leveled. There is no need for heavy equipment, clean, fast, and non-disruptive to your surroundings.
