High-Density Polyurethane Resin Injection

High-Density Polyurethane Resin Injection For Non-Invasive Foundation Repair

UMA Geotechnical Construction (UMA) is the pioneer in deep soil improvement using High-Density Polyurethane Resin Injection, or as we call it HDPR Injection. With this innovative tool in our pocket, we can seal leaky pipe joints, lift and level buildings, improve soil bearing capacities, and more, all while only leaving behind small one-inch drill hole marks. HDPR Injection is perfect for your historical or otherwise sensitive projects.

Please contact us today to hear more about our High-Density Polyurethane Injection process and how we can help on your commercial, municipal, DOT, or residential project!

Over 4,000 HDPR Soil Injection Projects Completed By UMA

UMA Geotechnical Construction has used our HDPR soil Injection process successfully for over 4,000 deep soil improvement projects. Why not add your name to that growing list?

Our HDPR Injection process is unique because of our expanding hydro-insensitive polymer that can be injected precisely at the soil strata depth you need between 1/2″ and 3/4″ holes. UMA can make multiple soil injections at varying depths to build columns of vertical support reaching down 30 feet and beyond.

This process is specially formulated for our clients. UMA’s High-Density Polyurethane Injection will save time on your project, give you assured soil stability, and is guaranteed to fight against any significant shrinkage.

Advantages of Our Specially- Formulated Expanding Polymer

There are many advantages to the expanding polymer tested and developed by the UMA Geotechnical Construction staff. Here are some of the reasons why our soil injection is better than our competitors:

  • No significant shrinkage or deterioration guaranteed
  • On-site soil testing and laser equipment accuracy
  • Lightweight system that is less than 10% the weight of cement grouts
  • Time needed for project completion is dramatically reduced
  • The cured polymer is environmentally neutral and won't contribute to pollution, leaching, and soil or water contamination.

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.
