Top-Rated Micropile Installation

Micropiles are useful in situations where access is limited. We use this deep foundation technique for correcting structural settlement, providing support for excavations, and resisting uplift and dynamic loading. With design loads between 3- and 500-plus tons and a depth capacity of up to 200 feet, micropiles offer comparable performance to other conventional deep foundation pile systems like helical piles. Each micropile includes steel elements that are bonded into the bearing soil or rock for optimum stability. Installation for our micropiles requires drilling  2-12 hole inches in diameter into the bedrock in which the micropiles then bond to the rock socket wall for load transfer. Grout is then pumped or pressure fed into the opening. The casings of the micropile are then lifted to the top of the bedrock to enable bonding to the bar.

As you can see, UMA Geotechnical Construction is committed to properly installing all our deep foundation systems and pilings to make sure that your project is as secure as possible. Mircopiles are great to use in structural support because they are cost-effective, can be installed in almost any ground solution, and can provide a high-load capacity at low total and permanent settlement.

Solid Underpinning Foundation Solutions

One of our other popular deep foundation solutions is underpinning foundations. Underpinning is the process of reinforcing or strengthening existing foundations. This service is often used to stabilize conditions when existing foundations settle, soil properties change, or nearby excavations cause foundation movement. Some of the Design-Build solutions UMA Geotechnical Construction provides to help with underpinning foundation are micropiles, jacked piers, helical piers, or chemical grouting.

Our team is also equipped to help with any emergency underpinning foundation needs your project may be experiencing, like heavy rainfall damaging a bridge or repair needed immediately to another infrastructure. We make sure that all our geotechnical engineers are equipped and well-trained to tackle any underpinning solution your project may need. You can rely on us to have the knowledge, experience, and tools to make your project safe and secure. Learn more about our underpinning foundation solutions when you fill out an online form today!

City of Durham

The City has worked on two larger projects with UMA. Both projects exceeded our expectations and were delivered on-time and on–budget. I would encourage anyone seeking soil and structure stabilization to consider UMA based on the successful projects they have delivered for the City of Durham.
