Micropile Underpinning for Foundation Repair

Micropile underpinning is a sophisticated foundation repair technique that has proven to be effective in retrofitting and rehabilitating buildings. It involves the installation of small diameter piles that are drilled and grouted deep into the ground beneath the foundation. This technique is particularly useful in situations where traditional foundation repair methods cannot be used due to site access or other limitations.

Micropile underpinning has been used successfully in a variety of applications, including seismic retrofitting, foundation reinforcement, and bridge rehabilitation. With its versatility and efficiency, micropile underpinning is a powerful foundation repair solution that should be considered by all property owners facing foundation problems.

Benefits of Micropile Underpinning

Micropiles are deep foundation friction piles constructed using high strength steel casings. A friction pile allows transfer of some of the pressure put on them to the soil around them. The friction creates an adhesive effect where the pile and the soil connect. Micropile underpinning is the process of creating small diameter drilled and grouted friction piles. Hollow bars are then installed via the injection bored method to complete the underpinning process.

The injection bored method is when hollow bars are installed then pumped full of a cement grout mixture while an anchor is drilled into the grout. There are several advantages to using the micropile underpinning process offered by My Foundation Repairs:

  • Fast and effective
  • Drilling and grouting completed at the same time
  • Ability to use smaller equipment thus able to work in smaller spaces at a lower cost
  • Improves the ground
  • Offers a higher skin friction protection

How Micropile Underpinning Works

Micropile underpinning uses small-diameter piles to support and stabilize a foundation. The micropiles are installed using a small drilling rig, and they are usually made of steel or concrete. The piles are driven into the ground until they reach a stable stratum, and then they are grouted in place.

Once the micropiles are in place, the load from the foundation is transferred to the piles, which helps to stabilize the foundation and prevent further settling. In some cases, additional reinforcement may be needed to ensure that the micropiles can carry the load of the foundation. However, micropile underpinning is typically a cost-effective and efficient way to stabilize a foundation and prevent further damage.

When Micropile Underpinning is Necessary

Micropile underpinning is a process of reinforcing the foundation of an existing structure by installing small-diameter piles. This technique is often used in situations where the soil is too weak to support the weight of the existing structure, or when the structure has settled and needs to be lifted back into place.

In some cases, micropile underpinning may also be used to stabilize a slope or hillside. The piles are installed using a small rig, and they are usually made of steel or concrete. Micropile underpinning is a relatively quick and simple process, and it can be completed with minimal disruption to the day-to-day operations of the existing structure.
