From various sub-base materials and paving sands, to bags of cement and mortar, for collection or delivery. Visit www.roadstone.ie or contact your local Roadstone Retail Outlets. RECESSED MANHOLE COVERS
Manhole covers are an essential ingredient of any paving layout as they provide vital access to underlying services and must be clearly identifiable within your garden or driveway design.
From Urbana Paving to Cobblesett, all of the Roadstone Paving range can be laid within the manhole cover to provide continuity of colour, texture and pattern.
Various sizes and strengths are available (contact local retail shop for more details).
