GRC 450 x 450 Promenade Slabs

All our 450 x 450 mm Promenade Slabs are manufactured and tested in accordance with BS 1339. This ensures that our slabs are strong, durable and slip resistant and can be installed on a flat roof or balcony with complete confidence.

Our 450 x 450 mm Promenade Slabs can be laid using our range of support pads or they can loose laid as ballast as they exceed the wind uplift requirements of 80kg per m2.

Starting at only 16kg each they are also very easy to handle and under the 25kg lifting limit recommended by the Heath & Safety Executive.

Please select a surface finish from the options below to see the full colour range and further BS 1339 test results for each type.
