Description: Protect your home or business with professional earthing and lightning protection installations from GossTech. Serving Nairobi and all major towns across Kenya β testing, installation, maintenance and emergency repairs. Contact 0723613664 | info@gosstech.co.ke | www.gosstech.co.ke
Introduction β Why earthing and lightning protection matters
Lightning strikes and electrical faults are unpredictable, but their consequences are often painfully predictable: damaged electronics, fires, injury, and downtime. A robust earthing (grounding) system combined with a correctly designed lightning protection system significantly reduces these risks.
At GossTech, we design, install and maintain earthing and lightning protection systems tailored to Kenyan soils, weather patterns and building types. Whether you manage a residential estate in Nairobi, a commercial complex in Mombasa, or an industrial facility along Thika Road, our certified electricians ensure your electrical safety meets local regulations and international best practice.
In this comprehensive pillar post you will find:
- A clear explanation of earthing and lightning protection systems and why theyβre essential.
- The GossTech approach to testing, installation and maintenance.
- Detailed service area coverage and what we do in each area.
- A full list of Nairobi estates we serve and the services available to them.
- Useful tables, FAQs, and a call-to-action so you can get protected fast.

What is earthing (grounding) and how does it protect you?
Earthing (or grounding) creates a low-resistance path for fault currents and lightning-induced surges to safely dissipate into the ground. Proper earthing:
- Protects people from electric shock.
- Prevents damage to sensitive electronics and appliances.
- Lowers fire risk from stray currents.
- Stabilizes voltage levels across the electrical system.
Key components of a good earthing system include earth electrodes (rods or plates), earth conductor, earth pit, earth enhancement materials (where soil resistivity is high), and bonding to metallic structures and exposed conductive parts.
Earthing vs. lightning protection β how they work together
Earthing is the foundation that safely dissipates currents. Lightning protection is a system that intercepts lightning strikes (air terminals/rods), conducts the surge via down-conductors and safely disperses energy into the earth via an earthing system. Without effective earthing, a lightning protection system cannot do its job.
GossTech’s services: What we offer
We provide end-to-end earthing and lightning protection services for residential, commercial, industrial, and institutional clients across Kenya. Our service suite includes:

Our approach β how GossTech delivers reliable protection
- Survey & soil testing: We begin with a full on-site survey and soil resistivity testing. Kenyan soil varies significantly between coastal, highland and arid regions β the right solution depends on accurate data.
- Design: Using test data and electrical load information, we design a tailored earthing and lightning protection system. For large installations we model down-conductor paths, air terminal placements, and bonding points.
- Installation: Our certified electricians install electrodes, down-conductors, clamps and bonding. We use corrosion-resistant materials and industry-grade SPDs to extend service life in Kenyan conditions.
- Testing & commissioning: After installation we test earth resistance (mΞ©/Ξ© depending on system size), continuity, and SPD operation. We produce a full report and commissioning certificate.
- Maintenance & monitoring: Regular inspections and SPD replacements keep your system working. We offer maintenance contracts tailored to client needs.

Example project types and case studies (brief)
1. Gated community in Kilimani β Earthing retrofit
Problem: Frequent tripping and equipment failures during storms.
Solution: Soil resistivity tests revealed uneven grounding. We installed a ring earth with supplementary chemical electrodes and fitted Type 1+2 SPDs on the incoming supply. Result: Reduced transients and improved equipment reliability.
2. Coastal hotel in Mombasa β LPS & corrosion control
Problem: Salt-laden air corroding down-conductors and clamps.
Solution: Marine-grade copper-bonded conductors, sacrificial anode protection and a scheduled maintenance plan.
3. Industrial park near Thika β Earthing grid
Problem: High fault currents and multiple large motors.
Solution: Designed and installed a large earthing grid with buried conductors, multiple earth pits and equipotential bonding to reduce step and touch voltages.

Frequently Asked Questions (FAQ)
Q: How often should earthing be tested?
A: We recommend annual testing for commercial and industrial sites, and every 2β3 years for residential properties, or after any major electrical work.
Q: My home trips frequently during storms β do I need lightning protection?
A: Frequent tripping can be caused by surges rather than direct strikes. Installing SPDs and improving earthing often resolves this. A site survey will determine the right solution.
Q: Will earthing prevent lightning strikes?
A: No β earthing does not prevent strikes. It safely dissipates the energy of a strike or surge to reduce damage.
Q: What materials do you use?
A: We use copper-bonded steel rods, copper conductors where required, marine-grade materials for coastal sites, and certified SPDs from reputable manufacturers.
Q: Are your electricians certified?
A: Yes. Our team is licensed and follows NEMA, IEC and local safety standards for earthing and lightning protection.
