Earthing & bonding
Earthing is the quietest system in a building and the one most often taken on trust. It carries no load, shows no symptom and gives no warning — until a fault current needs somewhere to go. Our earthing work starts with measurement of the actual ground, not a value copied from a previous project.
Earth electrode systems
Design and installation of copper-bonded driven rods, extensible deep-driven systems, earth mats and ring electrodes, buried conductors, chemical and enhanced electrodes, and earth enhancement compound where resistivity is high or ground space is limited.
Earth resistance testing
Two standard field methods — fall-of-potential and clamp-on. One method is taken at commissioning and the other at every inspection after, logged against that first baseline.
One reading tells you the value today. A run of readings tells you whether the system is quietly getting worse — which is the thing you actually want to know.
Bonding of services and structure
Metallic services, roof plant, handrails, façades and cladding bonded so that everything a person could touch sits at the same voltage during a fault or a strike — with separation distances calculated rather than eyeballed, and every addition since handover accounted for.
