Specialist Environmental Civil Engineering
Some projects need more than standard groundworks — pond linings, bypass separators, attenuation systems and bespoke environmental works require contractors with the right training, the right equipment and proven experience installing them properly.
Based in Mountain Ash, C&M Jones delivers specialist environmental and civil engineering works across South Wales — supporting developers, infrastructure projects and environmental schemes that demand technical expertise beyond the everyday.
With CHAS accreditation, confined spaces certification and decades of combined experience on technically demanding projects, we're trusted to deliver the specialist works that other contractors won't take on.

Specialist Works, Delivered Properly
Environmental and specialist civil engineering works don't suit generalist contractors. A badly installed pond liner leaks, a separator fitted incorrectly fails its compliance check, and confined space works carried out without proper training are dangerous.
We bring the right accreditations, the right equipment and the technical experience to deliver specialist works to the standard the project requires. From pond linings installed and welded properly, to separators fitted to manufacturer specification, every job is handled by trained operatives who know what they're doing.
From environmental schemes to infrastructure support packages, we're the contractor developers and engineers turn to when the work needs to be done right.
