Geotechnical Services
Our geotechnical staff consists of five professional engineers licensed in the states of Pennsylvania, Ohio and West Virginia and one engineer in training. Two of the professional engineers holds a Masters Degree in Civil Engineering, specializing in foundations and site improvement theory. Our engineers are assisted by six geologists/wetland specialists who have extensive experience in the geotechnical engineering field.

PS&R’s expertise and services include, but are not limited to:
Geotechnical Studies and Subsurface Investigation From Preliminary Soils, Geology & Mining Reviews to full scale Subsurface Investigations, PS&R takes great pride in developing and completing comprehensive, site specific geotechnical recommendations and reports. We maintain first hand contact with numerous drilling (both geotechnical and air-rotary) and earthwork (test-pit excavation) contractors to coordinate responsive, cost-effective explorations on even the most difficult and demanding project sites. 
Our experience in soil stabilization can aid in constructing stable subgrade conditions on the most difficult of project sites. Soil and Subgrade Stabilization PS&R has specialized experience in soil and subgrade stabilization utilizing chemical additives including Portland cement, lime, and industrial byproducts such as lime kiln dust (LKD) and flyash. From collecting samples; to completing mix designs to determine the most cost effective additive and application rate; to monitoring and field testing, PS&R has the experience and resources to provide cutting edge solutions for soil and subgrade stabilization projects. Full Depth Reclamation Based on the recent acceptance and advancement of Full Depth Reclamation(FDR) throught Pennsylvania (which now has an approved specification package through PennDOT) PS&R has invested in the laboratory and field equipment required to provide sampling, laboratory mix design and field monitoring services. We have worked with local Townships, Municipalities and Contractors on numerous projects over the last few years in Pennsylvania and Ohio. |
Mining Evaluation and Mine Stabilization PS&R specializes in the evaluation of existing mining conditions and providing recommendations for stabilizing both strip and deep mined project sites. We are currently the PADEP's min subsidence consultant responsible for the coordination and monitoring of subsidence claim investigations. PS&R has also coordinated and monitored the successful saturation grouting of numerous deep mined sites in the Pittsburgh area. Geotechnical Instrumentation PS&R’s experience in geotechnical instrumentation includes the installation, data acquisition and evaluation of slope inclinometers (slope stability analysis), developing and monitoring settlement programs for embankments and structures, installation and measurement of crack monitors (building distress) and installation and monitoring of groundwater wells (piezometers). 
PS&R was an integral part of the design team for this soldier pile and lagging wall constructed along Cavitt Road in Murrysville, PA. Retaining Structures PS&R has specialized expertise in the evaluation and design of Mechanically Stabilized Earth (MSE) retaining walls. We are familiar with most of the locally available wall manufacturer units including Versa-Lok, Keystone, Allan Block and Redi Rock. We utilized SRWall and manufacturer specific design software in our evaluation and design services. We strive to provide site specific wall design and construction drawings for even the most simplistic of retaining walls. We also provide geotechnical consultation services (review and recommendations) for larger soldier beam and lagging walls, retaining walls requiring tie-backs (tendons and/or deadmen), gabion walls and other gravity structures.
