Height Adjustable Surface Boxes with Fugenring
Height adjustable Surface Boxes with so-called 'Fugenring', a placeholder ring allowing the installer to exchange the ring with a bituminous liquid asphalt for a long lasting joint between asphalt and Surface Box.
Surface box VF
Strong, lightweight, and built for a perfect asphalt connection - fully compliant with industry standards
The VF Series from AVK Plastics delivers a smart solution for utility access in asphalt roads. Designed with a heat-resistant recycled plastic body and a heavy-duty cast iron lid, these surface boxes combine easy handling with long-term durability.
A specially designed joint ring creates a precise gap between the asphalt and the lid during installation. This gap is later filled with a flexible bitumen seal, ensuring a watertight and long-lasting bond—exactly in line with ZTV Asphalt and ZTV FUG-StB 15 guidelines.
