On Tuesday March 12th, 2019 there will be a presentation made for NYSSPE members on the topic of Trenchless Underpinning: A Method to Underpin Foundations and Stabilize Soil Without Excavating, using a chemical grout injection technique. The 1-PDH presentation will be made by Tony Alfano of Ground Works Solutions at the conference room of Brooker Engineering in Suffern, NY. For more information about the presentation and to RSVP, click here.
The presentation will provide a review the technical specifications of the URETEK chemical grout and its application on soil stabilization. The course will discuss the chemical reaction and the effect on temperature and pressure as it applied to various soil conditions. The chemical injection effectiveness and limitations will be discussed at various depths from 3 feet to 50 feet below grade. We will discuss our solution for the following applications:
- Sub-terrain void fill and high rise underpinning.
- Seawall, bulkhead, ground water and injectable barrier containment.
culvert, spillway, and sewer and dam repair. - Soil stabilization for bridge approaches and rail ballast.
- Slab lifting.
I want to make sure that my home is sturdy, but I’m not sure how to go about it. It makes sense that I would want to get my home underpinned. That seems like a great way to make my home way more sturdy.
I can see how a business could really benefit from getting the right kind of underpinning for their building. Having the work done by a professional could allow them to be safer. it was interesting to learn about how they can stabilize the soil without excavating the area.
