From calculation to delivery report

01

Calculate

Enter the postal code. BRO provides soil type, groundwater and pH. The calculator determines the required rod depth.

02

Invite

Send the field engineer a digital task order by email — including expected rod depth and target resistance.

03

Measure

The engineer confirms the field measurement on their phone. EarthGND archives the measured result.

04

Report

Generate and sign the NEN 1010 part 6 delivery report. Immediately available in your project file.

Always free
