Earthing resistance.
From calculation to proof.
Calculate grounding resistance, determine the optimal rod depth and automatically generate a NEN 1010 delivery report. One platform for installers who want to work faster and deliver with confidence.
From calculation to delivery report
Calculate
Enter the postal code. BRO provides soil type, groundwater and pH. The calculator determines the required rod depth.
Invite
Send the field engineer a digital task order by email — including expected rod depth and target resistance.
Measure
The engineer confirms the field measurement on their phone. EarthGND archives the measured result.
Report
Generate and sign the NEN 1010 part 6 delivery report. Immediately available in your project file.
Resistance Calculator
Calculate the maximum grounding resistance per NEN 1010. Choose your grid, installation type and RCD — get four output layers instantly.
- Resistance Calculator unlimited
- TT and TN grid systems
- NEN 1010 standards
- No account needed
Rod Depth Calculator
Enter a postal code. EarthGND automatically retrieves soil type, groundwater depth and pH from BRO — and calculates the required rod depth.
- BRO soil data by postal code
- Risk class I – IV
- Three scenarios (favorable/average/unfavorable)
- Invite field engineer by email
- NEN 1010 part 6 delivery report
- PDF report & email delivery
BRO Soil Data
Soil type, groundwater depth and pH directly from the Dutch Soil Registration by postal code.
NEN 1010 standards
All calculations conform to NEN 1010, NEN 62305 and NEN 50522 — including legal maximum.
Signed delivery report
From rod depth calculation to a digitally signed NEN 1010 part 6 delivery report — including field measurement and file archive.
