Where durability is not a concern we also offer plastic distance tubes as an alternative to fibre-reinforced concrete distance tubes. These special tubes have a roughened exterior surface to give some minimal adhesion to the concrete. Tubes are supplied in 2,000mm lengths with sealing end cones to suit.

Plastic distance tubes have minimal adhesion to concrete and due to movement caused by thermal variations, cracks at the interface between tube and concrete can develop. If the plastic tube is to remain in place then it needs to be sealed both internally and externally.
