We are an independent soils testing laboratory. Dedicated to quality, we strive to provide accurate and timely results to our clients. We have the experience, knowledge and expertise to handle the most demanding jobs with integrity and attention to customer service. We offer high-quality test reports, free sample pick-up, an AASHTO-accredited soils laboratory (w/extensive ASTM knowledge and experience), dedicated customer service, and prompt attention to your project. Our ultimate goal is to assist our clients with successful completion of their projects by providing them with reliable data, competitive fees, and timely service.


We have extensive experience in the testing of soils in the Baltimore, Washington, Virginia, and Pennsylvania regions for countless design and construction projects. These projects include, but are not limited to, private and public facilities and roadways, universities, churches, federal buildings, businesses, interstate highways, airports, waste water treatment plants, schools, substation upgrades, military bases, landfills, and much more.


Previously based in Baltimore, Maryland, many of our clients are located in the Maryland, Virginia, and Pennsylvania region where we typically pick-up samples from our clients' offices. We also receive samples from our clients through carriers such as FedEx. We consider no project too small or too large. If your firm is considering sub-contracting some of your laboratory testing during high-volume periods, or looking for an independent, qualified and reliable materials testing laboratory, we look forward to meeting with you to discuss how we may best serve your firm.

We have provided independent soils laboratory services to more than sixty firms over the years. We believe that ultimately we have to answer to the Lord for our service. As a result, we focus on accuracy, quality control, and attention to detail. We strive to be a light in the industry and provide our clients with the highest quality of service while maintaining integrity and honoring God. We believe Christ works through us and provides to us completely. Thus, we ultimately have to answer to him for our work.
