Road Maintenance & Pothole Repair
Grading, Resealing & Murram Restoration
NCA licensed contractors with 15+ years experience maintaining roads across Kenya.
Roads Fail Deferred, Not Suddenly
Every failed road was a maintained road once — the failure was decided in the maintenance budget years before the surface showed it. Preventive maintenance costs a tenth of reconstruction.
This guide covers the full maintenance toolkit by Trust Partners Geo-Group, with construction foundations in our road earthworks guide.
The Pothole Formation Chain
- Water enters through unsealed cracks
- Base softens — water weakens subgrade
- Surface fatigues — traffic flexes weakened layer
- Chunks work loose — pothole is born
- Grows geometrically — each wheel deepens cavity
The Six-Step Permanent Pothole Repair
- Cut — rectangular geometry, vertical edges
- Clean — remove loose material, dust, water
- Tack — bituminous coat on faces and base
- Fill — hot asphalt mix in lifts
- Compact — plate or roller to refusal
- Seal — perimeter flush, no water entry
Throw-and-go patches fail in months. Permanent repair is a method, not a material. Contact our team.
Grading: The Recurring Discipline
- Active rural roads: Every 2-4 months
- Low-traffic roads: 1-2 times annually
- After storms: Inspection pass
Fleet: grader, water bowser, roller — a KES 150,000 pass protecting a KES 3M/km asset. See grader hire guide.
Equipment Fleet
Murram Restoration: When & How
Needed when: ruts deeper than grader recovers, corrugation returns in days, subgrade showing.
- Grade and shape first, correct camber
- Place 50-100mm fresh material, PI below 12%
- Water to optimum, compact to 95%+
- Finish tight, slightly proud
Every 2-4 years on active roads. See asphalt vs murram comparison.
Resealing: The Preventive Coat
Surface dressing seals cracks before the chain starts. Timing: on schedule, before distress shows. Window: dry weather, clean surface, proper chip spread.
Costs 2026 per km
