About SEL

The emergence of increasing legislation for the redevelopment of brownfield land provided the catalyst for the SEL Environmental (formerly the Civil Engineering Division of Site electrical Ltd) to become formally recognised as a dedicated sub-contractor working within the environmental sector since 1996. Initially working extensively within the landfill sector when Andy Shuttleworth took hold of the reins. Under Andy's control, SEL gained the necessary understanding and expertise to allow expansion to provide innovative gas protection measures relating to the redevelopment of contaminated land for industrial, commercial and residential use. SEL's expertise in welded membranes attracted opportunities in stormwater management (suds) when this market was in it's infancy some 10years ago. SEL worked with many of todays major drainage manufacturers to help develop their specific suds ranges. This expertise led to SEL's involvement in numerous CIRIA projects and the publication of several white papers. (listed below) SEL have developed a reputation to provide high quality systems and an all round service. SEL excel where the works aren't run of the mill and our engineering ability is put to the test to provide a technical solution.
