Permanent Highway Maintenance for Kent & the South East
Platinum 3Sixty focuses on permanent, low-carbon highway repair methods that reduce repeat visits, road user disruption and whole-life maintenance cost.
For recurring potholes, failed patches, alligator cracking and HGV-loaded surface defects, start with our dedicated pothole repair service.

Send us the location, photos and approximate dimensions of the defect. We can advise whether the issue is best suited to Elastomac, asphalt, joint sealing or another repair method.
Pothole Repair & Pavement Defects
Potholes usually form through a predictable cycle of cracking, water ingress, freeze-thaw expansion, traffic loading and surface breakdown.
Common causes of potholes
- Water entering cracks and joints
- Freeze-thaw expansion during colder weather
- Heavy traffic loading and HGV wheel paths
- Surface oxidation and binder ageing
- Weak or saturated sub-base layers
- Failed utility reinstatements and poor cold joints
Why temporary repairs fail
Traditional throw-and-go repairs often fail because they do not create a sealed, bonded repair. Water can enter the edges almost immediately, allowing the same defect to reopen.
Why permanent pothole repairs work better
Hot-applied permanent repair systems seal the defect, bond to the surrounding surface and help prevent water ingress. This helps break the cycle of repeated failure and repeat traffic management.
Pothole Repair Service
Permanent pothole repair for highways, car parks, retail sites, freight routes and commercial surfaces.

Elastomac Permanent Hot-Applied Repairs
Elastomac is a hot-applied, polymer-modified, waterproof repair system designed for permanent pothole repairs, cracks, joints, trench reinstatements, failed patches and surface defects.
Unlike cold-lay patching, Elastomac is installed hot, bonds into the existing surface and cures into a flexible, sealed repair. This helps prevent water ingress, cold joints and early failure.
Key advantages
- Permanent waterproof surface repair
- No cold joints
- Fast curing and rapid reopening to traffic
- Flexible under movement and loading
- Reduced repeat visits and lower whole-life carbon
- Contains recycled rubber from waste tyres
How Elastomac supports sustainable maintenance
Most reactive maintenance carbon is created by repeat interventions rather than the first repair alone. A longer-life repair reduces crew travel, plant movements, traffic management, waste and disruption.

High-Stress Areas: Bus Stops, Junctions, Freight Routes & Strategic Roads
Some highway locations fail faster because they are exposed to heavy braking, turning, standing loads, vibration, water ingress or repeated HGV movements.
High-risk locations
- Bus stops and bus lanes
- Junction approaches
- Roundabouts and turning areas
- Freight routes and HGV corridors
- Retail car parks and service yards
- Commercial access roads
- M25 corridor and South East motorway corridor approaches
Elastomac is particularly suited to many of these locations because it remains flexible, waterproof and durable under movement and loading.
Asphalt & Surfacing
Asphalt surfacing must provide strength, flexibility, waterproofing and skid resistance. Failures often occur when water, traffic loading or poor construction joints weaken the pavement layers.
Common asphalt materials
- Asphalt Concrete for binder and base courses
- Stone Mastic Asphalt for durable surface courses
- Hot Rolled Asphalt for high-strength surfacing
- Thin surface systems for fast resurfacing
- Cold-lay materials for temporary repair only
Typical surfacing defects
- Ravelling and fretting
- Fatigue cracking
- Edge failure
- Rutting and depressions
- Joint failure
- Patch failure
Long-life maintenance depends on selecting the right repair system for the defect, loading conditions and expected service life. For recurring potholes or failed patch repairs, see our pothole repair service.

MMA Road Markings & Highway Marking Systems
Road markings support driver guidance, lane discipline, pedestrian safety and traffic flow. Material choice is important in high-wear areas.
Common road marking systems
- Thermoplastic markings
- MMA cold plastic markings
- Preformed markings
- Water-based temporary markings
Why integrated repair and lining matters
On some sites, Platinum 3Sixty can complete permanent pothole repair and thermoplastic line reinstatement during the same visit. This can reduce repeat mobilisation, separate closures and disruption.
High Friction Surfacing
High friction surfacing improves skid resistance in areas where braking, turning or surface grip are critical. It is commonly used at junctions, crossings, bends, approaches and high-risk locations.
Typical benefits
- Improved skid resistance
- Enhanced road user safety
- Clear visual surfacing treatment
- Suitable for high-risk braking zones
- Durable finish when correctly specified and installed
Drainage & Water Management
Water is one of the biggest causes of highway deterioration. Effective drainage reduces standing water, protects the pavement layers and helps prevent potholes, cracking and edge failure.
Common drainage systems
- Gullies and gratings
- Slot drains and linear drainage
- Kerb drainage
- French drains and filter drains
- Carrier drains and pipe networks
Good drainage should be considered alongside permanent repair methods because sealing a defect is only one part of controlling long-term pavement deterioration.
Carbon & Whole-Life Cost
The lowest-cost repair is not always the lowest-cost solution. Repeated temporary visits can create higher total cost, more disruption and greater carbon output.
Carbon comparison
| Repair approach | Typical issue | Whole-life impact |
|---|---|---|
| Throw-and-go patching | Short service life and repeated failure | More repeat visits, traffic management, waste and carbon |
| Cut-and-patch | Better structural replacement but can create cold joints | Higher disruption and waste if not targeted correctly |
| Elastomac permanent repair | Requires specialist hot-applied equipment | Lower repeat visits, less waste and reduced whole-life carbon |
Key sustainability benefits
- Fewer repeat interventions
- Reduced traffic management
- Less waste disposal
- Lower operational carbon
- Recycled rubber content from waste tyres
- Better long-term value for highway authorities and asset owners

FAQs
What causes most potholes?
Most potholes are caused by water entering cracks, weakening the pavement and expanding during freeze-thaw cycles. Traffic loading then breaks away the weakened material.
Why do temporary pothole repairs fail?
Temporary repairs often fail because they do not create a waterproof bond with the surrounding surface. Water can enter the edges and the repair breaks down again.
What is Elastomac used for?
Elastomac is used for permanent pothole repairs, cracks, joints, utility reinstatements, failed patches, high-stress areas and other surface defects.
Is permanent repair better for carbon reduction?
Yes. Permanent repairs reduce repeat visits, plant movements, traffic management, material waste and disruption, which reduces whole-life carbon.
Where does Platinum 3Sixty carry out pothole repair?
Platinum 3Sixty prioritises Kent, East Kent, the M25 corridor and South East motorway corridors, with wider coverage across Essex, Surrey, Sussex and Hertfordshire for suitable works.
