Rayco Civils delivers professional groundworks, foundations, drainage and site preparation across County Mayo and all of Ireland. Trusted by developers, builders and homeowners — fully insured, accredited and equipped with modern plant.
Looking for reliable civil contractors in Mayo? Rayco Civils is an Irish-owned civil works and groundworks contractor delivering full site packages throughout County Mayo — from one-off homes and housing developments to commercial yards and infrastructure projects.
Our Mayo-based crews bring over 10 years of hands-on experience across groundworks, foundations, drainage, concrete works, excavation and site preparation. Every project is delivered safely, on programme and to current Irish standards.
Mayo sites typically mean peat and soft-ground foundation solutions, farm civils and coastal access works — so we price and programme each Mayo job around the ground conditions, access and drawings in front of us, not a generic rate card.
Whether you're a main contractor, developer, architect or private client in Mayo, we provide clear pricing, professional site management and proper RAMS documentation from day one — the same standard we bring to our work in Dublin, Wexford, Cork and as civil contractors across Ireland.
Our Mayo crews are part of Rayco Civils' national operation. See the full picture of what we deliver as civil contractors in Ireland, or jump straight to groundworks, foundations and drainage & ducting nationwide.
The two terms overlap on most Mayo sites. Groundworks is the substructure package on the building itself — site strip, bulk and reduced-level excavation, muck-away, imported and compacted fill, strip, pad or raft foundations, rising walls and the slab build-up. Civil engineering is the wider scope around it: foul and storm drainage, attenuation, ESB and telecoms ducting, kerbing, footpaths, access roads, hard standings and car parks.
We deliver both in Mayo, which matters because it is the interfaces between them that usually cause problems — a duct route that was never installed before the slab closed up, or a drainage fall that does not work with the finished levels. One contractor holding the levels removes that risk.
Everything is set out from the engineer's drawings and level datum. Formations are surveyed, fill is compacted in layers, pipe falls are checked before backfill and concrete dockets are retained, so the records the engineer asks for at certification exist rather than being reconstructed afterwards.

Yes. Groundworks — site strip, excavation, muck-away, compacted fill, foundations and slab — is the core of what we do in Mayo, and we also deliver the wider civils scope of drainage, attenuation, ducting, kerbing and access roads outside the building footprint.
Cost is driven by dig depth, ground conditions, muck-away volumes, imported fill, reinforcement, concrete volume and site access rather than by floor area. We price item by item from the drawings so each element can be checked.
We hold our own plant and operators, so mobilisation to Mayo does not depend on hire availability. Call 087 919 2193 to check the current programme before you fix a start date.
Yes. Taking clearance, dig, fill, foundations, drainage, ducting and slab as one package means one contractor is responsible for the levels and one set of records exists at certification.
