Company History


Vertase was founded in 2000 by a group of individuals from contracting and consulting within the contaminated land industry and are one of the longest established remediation contractors in the UK.  The business was developed, initially within the South West and expanded year on year with both project size and scope of works until its eventual opening of a second office in Sheffield in 2004. The company continued its growth organically up to its eventual purchase by FLI International in 2005.  With the size of projects expanding VertaseFLI made a decision to retain all the required skills in house which led to the development and opening of a dedicated in-situ treatment system and groundwater plant manufacturing centre close to the Sheffield office.  Over the years we have expanded our client base working for developers, housebuilders, manufacturing, industial and petrochemcial and public sectors.  

VertaseFLI now encompasses groundwater remediationcontaminated land remediationenabling works, demolition and site clearance and gas and VOC management as either discrete packages or projects or as a complete integrated solution.  

FLI International (The Group)

F.L.I. International Lining Systems was formed in 1984, based in Waterford, Ireland, which remains the head office location today. The sole business at that time was the welded installation of geomembrane lining systems for containment applications. F.L.I. gained a broad based knowledge of contracting within the geosynthetics industry and this business model was extended to the UK and mainland Europe with selected projects around the world.

The FLI Group has operated for 30 years and continues its expansion and development within the Environmental Contracting sector. With offices in Waterford, France, the UK and New Caledonia the group can offer true international capability across its services.
