UltraSlot is used in external pavement areas which are subject to constant traffic, such as airports, ports and areas with heavy-duty vehicles. The system is designed to ensure sufficient depth of concrete cover over the main body of the channel to withstand ultra heavy-duty loads.

The channel top edge has an outward fold for protection over the edge of the concrete encasement/surround, to prevent damage. Innovative channel features; concrete anchors, stabilising bars, channel feet and others, ensure the channel has a physical connection to steel reinforcing and is properly tied into the concrete encasement/surround, to create a strong, solid and durable structure.

UltraSlot Treadsafe Bar: A Treadsafe Bar can be fitted to the UltraSlot channel, which reduces the slot opening from 30mm wide to 2x9mm wide slots. This has no effect on the intake capacity of the system but will make the channel safe to cross when used in locations where pedestrians are walking over the pavement area.

CastSlot is ideal for areas of vehicular traffic such as car parks and industrial units where there is slow turning traffic.

  • Highways & Motorways

    Highways and motorways are under constant strain from heavy traffic and vehicles of various sizes. It’s important the surface drainage can manage large volumes of rainfall so that the road remains free and safe from excess water.

  • Distribution and Industrial Centres

    Distribution yards and industrial units typically have large surface areas to drain and must cope with heavy loads manoeuvring on a daily basis.

  • Petrol Stations & Forecourts

    Petrol stations and forecourts mean wide open spaces and constant weight of traffic. Robustness of the slot or channel drain is essential.

  • Bus Terminals

    Bus terminals and public transport facilities place heavy demands on surfaces and infrastructure. Strength and reliability are key criteria.

  • Container Ports

    Container ports and distribution yards are extremely hostile environments, pounded continuously by tractor and trailer units. Our robust range of slot drain and channel systems have been specifically developed with this in mind.

  • Ports & Docks

    Large ports and dock facilities are occupied by heavy, slow moving cranes that place high demands on the surface drainage. Only products with the highest specification are fit for this purpose.

  • Airports

    Airports around the world are seeing movements increase year on year and aircraft weights reaching new heights. With super jumbos like the Airbus A380 coming on stream, airside drainage is ever more of a challenge.
