Planning diamond drilling through reinforced concrete? Magnitude Geo provides targeted GPR and reinforcement scanning throughout London, the Home Counties and South East England.
Our surveys can investigate proposed drilling locations within concrete slabs, floors, walls, beams, columns and soffits before penetrations are formed.
Whether you require a single diamond-drilled penetration, several service openings or a larger drilling zone, we can develop a survey approach appropriate to the proposed works.
Send us your drawings, photographs and marked-up drilling locations where available. Our team can review the requirements and provide a free, no-obligation quotation.
Why Scan Concrete Before Diamond Drilling?
Diamond drilling can create penetrations through reinforced concrete slabs, walls and other structural elements. Reinforcement and other embedded features may be present within the proposed drilling location but cannot be reliably identified from the visible surface alone.
Targeted concrete scanning allows the proposed drilling area to be investigated before intrusive works commence. Survey findings can then be reviewed against the proposed penetration position before diamond drilling begins.
Targeted scanning around proposed diamond-drilled penetrations.
Reinforcement investigation around proposed core hole locations.
Scanning before mechanical, electrical and building-services penetrations.
Concrete investigation before new openings and alterations.
GPR Scanning Before Diamond Drilling
Ground Penetrating Radar is a non-destructive investigation method used to assess reinforced concrete before diamond drilling and structural penetrations.
Radar responses can provide information regarding reinforcement position, direction, approximate spacing and indicative depth within the surveyed area.
For proposed drilling locations, the survey can be concentrated around the intended penetration so that reinforcement responses can be assessed before the drilling contractor begins work.

Rebar Detection Before Diamond Drilling
Reinforcing steel is one of the principal features investigated where diamond drilling is proposed through existing concrete.
Where reinforcement responses can be clearly identified, their positions can be marked directly onto the accessible surface. This gives the drilling contractor and project team a practical reference before penetrations are formed.
Where more detailed information is required, surveys can also investigate reinforcement direction, approximate spacing and indicative depth.

Concrete Scanning for Diamond Drilling Works
Magnitude Geo can undertake concrete scanning around both individual diamond drilling positions and larger areas containing multiple proposed penetrations.
The survey extent can be tailored to the drilling zone, proposed opening size and structural element. Where several penetrations are positioned close together, scanning a wider area can provide a clearer understanding of the local reinforcement arrangement.
Detected reinforcement can be marked directly onto the concrete surface where required so that proposed drilling positions can be compared with the survey findings.
- Diamond-drilled service holes
- Core drilling locations
- Mechanical penetrations
- Electrical penetrations
- Ventilation openings
- Drainage and pipework penetrations
Scanning Before Service Penetrations
Diamond drilling is commonly used for new mechanical, electrical, drainage and ventilation routes through existing reinforced concrete.
Concrete scanning can support proposed pipework, cable routes, ventilation penetrations and other building-services installations where drilling is required through existing slabs or walls.
Where multiple penetrations are proposed, surveying the wider area can help establish the local reinforcement arrangement before drilling positions are finalised.
Diamond Drilling Through Slabs, Walls, Beams & Soffits
Magnitude Geo can undertake targeted scanning across a range of accessible reinforced concrete elements where diamond drilling is proposed.
Concrete Slabs
GPR investigation before floor penetrations, core drilling and building-services openings.
Concrete Walls
Targeted reinforcement scanning before horizontal diamond drilling and service penetrations.
Beams & Columns
Localised reinforcement investigation where drilling or structural connections are proposed.
Concrete Soffits
Scanning from below where diamond drilling is proposed through an accessible slab soffit.
For slab-specific investigations, visit our Concrete Slab Scanning London page.
Underside Slab Scanning Before Diamond Drilling
Where the upper surface of a concrete slab cannot be accessed, GPR scanning may be undertaken from the underside before diamond drilling through the structure.
This approach can be useful within basements, commercial buildings, car parks and refurbishment projects where the upper surface is occupied or otherwise inaccessible.
When scanning from the underside, interpreted depth information is referenced from the soffit surface being scanned.
Reference grids and detected reinforcement positions can also be marked onto the ceiling surface where required.
Diamond Drilling Survey Deliverables
Survey outputs can be tailored to the number of proposed drilling locations and the level of information required by the contractor or project engineer.

Concrete Scanning Before Diamond Drilling FAQs
Should concrete be scanned before diamond drilling?
Where the reinforcement arrangement is unknown, targeted GPR scanning can provide additional information around the proposed drilling location before work begins.
Can you locate rebar before diamond drilling?
Yes. Reinforcing steel can be investigated using specialist concrete scanning equipment and detected positions can be marked onto the surface where required.
Can you scan several drilling locations?
Yes. Individual penetrations can be investigated or a wider area can be surveyed where several proposed drilling locations are close together.
Can you scan concrete walls before diamond drilling?
Yes. Accessible reinforced concrete walls can be investigated before service penetrations and drilling works.
Can you scan from underneath a slab?
Yes. Where suitable access is available, GPR scanning can be undertaken from the soffit or underside of the slab.
Can detected reinforcement be marked on site?
Yes. Where appropriate, detected reinforcement positions can be marked directly onto the accessible concrete surface.
Can you provide a survey report?
Yes. Depending on project requirements, Magnitude Geo can provide annotated photographs, processed GPR outputs, reinforcement information and technical survey reports.
