Concrete Inspection Services, Inc. has been providing ground penetrating radar services to the Pacific Northwest since 2000.  Our mission is to provide a accurate and low cost service with a quick turn-around time.

Our specialty is concrete imageing in structural concrete and shallow utility locating.  

Equipment & Usage

2600 Mhz antenna is the highest resolution antenna available. It is a must for locating PVC conduit.  It is also the best choice for locating on pandeckhollow core slabswaffle decks, and any concrete structures less than 10".  

2000 Mhz antenna is the smallest  antenna available.  It is a high resolution antenna with a practical depth of 12".  It is the perfect choice for locations where overhead anchoring is required. It is also great on, CMU walls, beams, columns & restrictive areas.

1600 Mhz antenna is a high resolution antenna commonly used on post-tension slabs between 8" to 18" in thickness. It is also excellent for locating conduit in slab on grade.

1000 Mhz antenna is a deep penetration concrete antenna.  It is excellent for slab on grade applications where shallow utilities may be found just below the concrete. Also great for for thick concrete up to 24".

400 Mhz antenna is a deep penetration antenna. It can penetrate soil up to 6' in depth making it a excellent tool for locating UST'sPipe and Septic Fields.

RD8000 Radiodetection is a perfect compliment to GPR for locating utilitites.  Radiodection often locates live electrical beyond the reach of GPR.  Making it a excellent choice for concrete or asphalt on grade locating. Can provide a general location of electrical 10+ feet in depth
