The summer heat is just around the corner and that means early mornings for all of us. We want to remind all of our client to have plenty of water on site and start as early as possible. With the early hours approaching, we ask for a minimum of 24 hour notice for early morning starts especially for those concrete pours. GTI is here to help make those summer pours and inspections easier so please contact Pamela Martin at the GTI office (480-659-6630) as soon as possible to schedule your inspection times.

Everyone has been asking what is new with GTI and we are happy to share with clients that we are now providing drone services with our geotechnical, environmental and construction materials testing services. This includes aerial photos, videos, and site overview coverage. We have obtained FAA certification for our drone and our clients have retained us to fly over the site from the start of the project through completion and compile the video of site work with time. With the help of HERO Digital Marketing we are condensing the footage, adding music and providing our clients with a work of art they can use on their websites showing their projects from start to finish. Contact Jennifer at GTI ( for more info on our Drone services.

GTI looks forward to working with you this coming year. Please don’t hesitate to contact us if there is anything we can assist you with.

Thank you,
Jennifer Clark-Jones, M.S.
