Lightweight Watertight Covers

Double wiper watertight seal

Structural Science Composites Limited [SSC] offers lightweight watertight covers ideal for preventing surface water infiltration. (our C250 and D400 ranges can both be made watertight.)

When the watertight versions are required a plug and silicone seal can also be supplied.

Our lightweight watertight covers are used across the country where the prevention of water/liquids is paramount such as petrol stations, telecommunications complexes and lighting networks etc.

Structural Science have designed a “double wiper” action for their silicone seals which the first wiper cleans the frame as the cover is inserted and the second wiper makes a watertight seal.

The seal profile also contains an air void which allows the seal to make a secure contact with the frame.

This has also been tested under a 50 millilitre water head over the cover which has had a five ton weight placed in the centre of the cover.

For further information on how our watertight manhole covers can be used in specific applications and environments, please do not hesitate to contact our technical sales team for advice and guidance.
