Hayle does not sit on the same ground as the granite towns either side of it, and a foundation or a soakaway here has to answer to what is actually under the plot. We open it up and find out first.
Groundworks in Hayle varies more over a short distance than anywhere else on this stretch of coast.
Copperhouse, Foundry, North Quay, the Towans and the villages behind them are not one ground condition. Blown sand and dune, silt near the estuary, and made ground where two centuries of industry filled, quayed and reworked the waterfront: the town sits inside the Cornwall and West Devon Mining Landscape World Heritage Site for good reason, and that history is under the plots as well as around them. A hundred metres can change what a foundation has to be, which is why BS 8004, the code of practice for foundations, is a matter of proving the bearing stratum rather than assuming it.
The estuary decides the water. It is a protected tidal system, so where surface water is allowed to go is part of the design and not an afterthought, and a soakaway only works where the ground will actually take it. With harbour regeneration and new build plots still coming forward around Phillack, Angarrack, Gwithian and Connor Downs, that pairing, an unknown ground profile and a fixed drainage strategy, is the Hayle job in one sentence.
Most Hayle enquiries start below ground level, and several of the villages around the town are off mains drainage.
Site clearance, excavation to formation, muck away and foundations, with the dig used to prove what the plot actually sits on before anything is built back.
Foundations, slabs, formwork and steel fixing to the engineer's design.
Extensions, renovations and new build plots, taken from cleared ground to finished structure.
Foul and surface water runs, land drainage and attenuation, designed around where the water is permitted to go rather than where it is easiest to send it.
Soakaway design and installation on ground that has been tested rather than assumed, sized to the area it has to serve.
Installation and replacement for properties off mains drainage in the villages around the town, including the groundworks either side of the tank.
One contract across clearance, groundworks, drainage and buildThe same contractor holds the programme all the way through, so nothing on a Hayle plot stops while two firms agree whose scope it was.

Hayle work starts below ground: foundations taken to a stratum that has been proved, soakaways where the ground will take water, and surface water routed away from the estuary rather than into it. The nearest comparable work is elsewhere in west Cornwall, including 26 metres of soakaway installed in stages and three attenuation tanks built into the St Ives retaining wall scheme.

Great company to work with. Professional, reliable and well organised from start to finish. Communication is always clear, sites are well run & the team are a pleasure to deal with. I wouldn’t hesitate to recommend them and look forward to working together again!
Read more on GoogleCornwall Civils have been working on a complex external works package for our project in St Ives. Their works have included an extensive concrete retaining wall, in-situ concrete stairs and an in-ground modular drainage system.
Read more on GoogleCornwall Civils handled a tricky concrete shuttering, steel work, and pour for us on an emergency job. They stepped in at very short notice and worked through nights and weekends to get it done. The quality of their work was excellent, and their commitment was outstanding.

Hayle sits on the run between our base at Newlyn and the towns inland, so the area either side is regular working ground.
Send the postcode, the drawings and the stage the site is at. If nobody has opened the ground yet, say so, because on a Hayle plot that is usually the first thing worth doing.
