Height adjustable synthetic surface boxes enable quick and easy installation in tarmac. During rolling the top part is balanced and carried by the underlying tarmac layer and accurately aligned with the road surface.

The Swiss model is developed in cooperation with leading Swiss utility companies. The top part of these surface boxes is significantly strengthened compared with the standard height adjustable version, making it more robust, stable and resilient.

The newly developed height adjustable synthetic surface boxes with integrated “Fugenring” enable every road construction company to produce a durable joint between surface and surface box.
