# Tommy's GPR > Ground penetrating radar concrete scanning across Oklahoma. Tommy's Concrete Scanning LLC locates rebar, post-tension cables, conduits, pipes, and voids in slabs before anyone cuts, cores, or drills. Tommy's GPR (legal name: Tommy's Concrete Scanning LLC) was founded in 2020 by Tommy Grotts in Norman, Oklahoma. The company scans residential, commercial, and industrial concrete statewide. GPR works from one side of a slab, typically down to 24 inches, and does not require x-ray film or access to the ceiling below. Pipes, rebar, post-tension cables, conduits, and voids are located in the slab. A same-day Scan & Mark paints the floor. Custom 3D reports document layer-by-layer images, spacing, depth, and slab thickness. ## Contact - Phone: (405) 627-5263 - Email: tgrotts@tommysgpr.com - Hours: Monday–Friday, 7:00 am–5:00 pm; weekends by appointment - Base: Norman, OK 73071 - Facebook: https://facebook.com/Tommys-Concrete-Scanning-LLC-107885945138550 - Website: https://www.tommysgpr.com/ ## Pages - [Home](https://www.tommysgpr.com/): See through the slab before you cut - [What GPR Does](https://www.tommysgpr.com/what-gpr-does/): How ground penetrating radar maps what is in concrete - [Services](https://www.tommysgpr.com/services/): Scan & Mark and Custom 3D Reports - [Scan & Mark](https://www.tommysgpr.com/services/scan-and-mark/): Same-day marks on the slab - [Custom 3D Reports](https://www.tommysgpr.com/services/3d-reports/): Layer-by-layer documentation - [Residential](https://www.tommysgpr.com/residential/): Homes, remodels, and residential trades - [Commercial](https://www.tommysgpr.com/commercial/): Offices, retail, healthcare, and schools - [Industrial](https://www.tommysgpr.com/industrial/): Plants, warehouses, and energy floors - [Service Areas](https://www.tommysgpr.com/service-areas/): Oklahoma cities we scan most - [About](https://www.tommysgpr.com/about/): Tommy Grotts and Tommy's Concrete Scanning LLC - [Contact](https://www.tommysgpr.com/contact/): Request a scan ## Oklahoma service-area pages - [Yukon](https://www.tommysgpr.com/service-areas/yukon/) - [Oklahoma City](https://www.tommysgpr.com/service-areas/oklahoma-city/) - [Moore](https://www.tommysgpr.com/service-areas/moore/) - [Mustang](https://www.tommysgpr.com/service-areas/mustang/) - [Norman](https://www.tommysgpr.com/service-areas/norman/) - [Tulsa](https://www.tommysgpr.com/service-areas/tulsa/) - [Shawnee](https://www.tommysgpr.com/service-areas/shawnee/) - [Ardmore](https://www.tommysgpr.com/service-areas/ardmore/) (also searched as Admore) - [Pauls Valley](https://www.tommysgpr.com/service-areas/pauls-valley/) - [Chickasha](https://www.tommysgpr.com/service-areas/chickasha/) ## Optional - [Sitemap](https://www.tommysgpr.com/sitemap.xml) - [Robots](https://www.tommysgpr.com/robots.txt)
