Heavy-Duty Composite Manhole Wells & Covers
Engineered for maximum integrity. Our 100% water-tight secondary containment systems protect your critical underground assets against water ingress and heavy traffic loads.
Engineering Excellence
Our composite manhole systems set the industry standard for environmental safety and structural performance.
100% Water-Tight
Advanced electro-fusion welding and mechanical flange seals prevent ground water ingress, keeping the well interior bone-dry for critical equipment.
D400 Load Rated
Tested to EN124 standards, our composite covers handle up to 40 tons of dynamic pressure—ideal for heavy fuel tanker traffic areas.
Chemical Proof
Constructed from high-density HDPE and SMC resin, the system is immune to fuel vapors, soil acidity, and aggressive industrial chemicals.
Anti-Static Safety
Featuring a non-slip textured surface and specialized anti-static grounding, ensuring zero spark risk in explosive fuel station environments.

Versatile Application Environments
Gas Station Forecourts
Designed for the high-traffic demands of fuel stations. Our D400 rated composite covers withstand constant tanker and customer vehicle movement, while the PE wells ensure zero water ingress into the tank manway space.
- Fuel Vapor Resistant
- Non-Slip Grid Surface
- Grounding Protection
- Quick Access Locks
Hazardous Containment Nodes
In petrochemical and industrial processing plants, our manhole systems provide secondary containment at pipeline junctions, preventing hazardous spills from contaminating the surrounding soil or groundwater.
- Corrosion-Free HDPE
- Acid & Alkali Proof
- Airtight Sealing
- UV Stabilized Material
Smart City Utility Ducts
Ideal for urban telecommunication and electrical networks. The composite covers provide signal transparency for IoT sensors within the well, while the lightweight design reduces the risk of back injuries for maintenance crews.
- Signal Transparent
- Anti-Theft Design
- Reduced Lift Weight
- Custom Branding
