3D Imaging Concrete
Structural Mapping of concrete is an application used to determine position or depth of anything embedded within a concrete structure; these targets include re bar, cables, conduits etc. 3D imaging documentation will be supplied with this service.
Non-Destructive Investigation of Concrete Structures with 3-D Imaging
Finally, a quick, easy, safe and effective way to locate buried obstruction in concrete structures prior to drilling, cutting or coring. We can inspect walls, floors, decks, slabs, tunnels, balconies and garages. Now it is possible to locate rebar, tension cables, conduits, voids and even measure slab thickness. Our technology can find objects beneath the surface to a depth of 18 inches. It is possible to detect and map the relative concrete condition in conjunction with planning and to combine separate 3D grids into single grid for increased coverage of an area. Ground Penetrating Radar (GPR) and Ferrous metal concrete scanning technology for Non-Destructive Testing (NDT). The systems we use coupled with highly experienced operators result in very accurate location, depth and identification of materials in concrete structures.
We only use equipment that is safe to use around people without any special safety constraints or set up requirements and operates on a non-interference basis with our clients normal business. This includes scanning around sensitive electronics, computer equipment and hospital measuring devices. This, coupled with our high mobility and quick set up time, allows us to perform the scanning tasks very quickly during normal business hours.
Structural Imaging provides concrete scanning services for:
- Locating safe areas to core drill new stacks for electrical and plumbing
- Locating safe areas to anchor HVAC, Mechanical and seismic anchors
- Determining safe areas to cut doorways, stairways and door openings
- Slab thickness assessment/survey: Slab on Grade (S.O.G) and elevated
- Locating structural beams: S.O.G. and elevated
- Locating utility pipes under concrete and pavement
- Locating rebar and post tension cable (vertical and horizontal) in concrete
- Determine size and precise location of reinforcement within concrete
- Identify and mapping reinforcing steel and hydronic lines within concrete
- Map and identify conduits and utility cables within concrete
- Identify air/water filled voids in or behind concrete
We can provide all scanning views in either paper copy or electronic format in both two and three dimensions. In small areas were complex or crowded targets are identified we can generate images in ¼ inch slices to a depth of 18 inches to improve the identification of materials in the concrete.
Some examples using concrete scanning services:
- Identifying safe areas to core drill new holes for electrical and plumbing
- Determine safe areas to drill HVAC, Mechanical and seismic anchors
- Locating safe areas to cut walls openings for doors and windows
- Slab thickness measurements for Slab on Grade.
- Locating structural beams: S.O.G.
- Locating existing utility pipes under concrete and pavement
- Locating rebar and post tension cable (vertical and horizontal) in concrete
- Determine approximate size and precise location of reinforcement within concrete
- Map and identify conduits and utility cables within concrete
- Identify voids in or behind concrete
Benefits over Radiography (X-Ray):
Unlike x-ray technology, concrete scanning with GPR requires only single sided access to perform surveys. This means slabs of all types may now be scanned. No site hazards or need to close off work areas as with radiography. Hundreds of square feet can be inspected in a day. We can even view 3D results on screen while on the project.Concrete Inspection
locate metallic and non-metallic targets in walls, floors; we can locate embedment within concrete structures prior to drilling, cutting, coring or use scanning information to determine pre–build location of future projects.- Structure inspection – monuments, walls, towers, tunnels, balconies, garages, decks
- Concrete cover depth on new structures
- Concrete inspection – locate metallic and non-metallic targets in walls/floors
- Measure slab thickness
- Void detection and location
- Inspection of other reinforced concrete structures
- Easy identification of re-bar location and depth
- Ability to obtain accurate overlay thickness
- Determine accurate concrete cover depth
- Define areas of deterioration
