Annual earth resistance testing, inspection, and compliance certification for existing earthing systems across Dubai — required for DEWA and Dubai Civil Defence compliance, and for renewing Building Completion Certificates. If your earthing system hasn’t been tested in the last 12 months, or you need a certificate for an upcoming inspection, this is a same-scope service independent of any new installation work.
We test using the Fall-of-Potential method, the industry standard for accurate earth resistance measurement — a resistance curve is plotted using temporary test probes at set distances from the electrode, rather than a single-point reading that can be misleadingly optimistic. Results are checked against the threshold relevant to your installation (typically under 1.0 Ω for main panels and substations), and Dubai’s arid, high-resistivity soil means a system that tested fine on installation can drift out of compliance over time as ground moisture conditions change seasonally.
Testing is paired with a visual inspection of the earthing network — checking for corrosion at exothermic weld joints and clamps, continuity of bonding connections to metallic building services, and physical condition of earth pits and inspection chambers. On completion, we issue a formal Earth Test Certificate documenting the measured resistance and pass/fail status against the applicable standard — the document typically required for DEWA compliance checks, Dubai Civil Defence inspections, and Building Completion Certificate renewals.
Annually, at minimum — DEWA and Dubai Civil Defence compliance checks generally expect a current (within 12 months) Earth Test Certificate. Facilities with critical loads, such as data centers, or with especially corrosive/high-salinity ground conditions may warrant more frequent testing.
It depends on the installation type — main panels and substations typically need under 1.0 Ω, while general building earthing thresholds can be somewhat higher depending on the applicable standard and site classification. We test against the specific threshold relevant to your installation, not a single blanket number.
Yes, if you need to pass a DEWA compliance check, a Dubai Civil Defence inspection, or renew a Building Completion Certificate — these require a current, dated Earth Test Certificate as documentation, independent of whether the system is subjectively “working fine.” An earthing fault often has no visible symptoms until the moment it’s needed during an actual fault current event.
We identify the specific cause — commonly a corroded connection, a degraded electrode, or soil resistivity that’s drifted since installation — and provide a scope and quote for the remedial work needed to bring it back into compliance, which is often a targeted repair rather than a full system replacement.
Yes — testing and certification is an independent service. We test to the same Fall-of-Potential method and standards regardless of who installed the original system.
