The Company was established by Chris Blackwell in 1956 with activities focused on providing subcontract earthworks capabilities to main contractors engaged in the national motorway network construction programme. The business developed to become a major earthworks subcontractor and one of the largest plant fleet operators in the UK. A subsidiary was established in 1967 to undertake work in Northern Ireland.

Subsequently the company has engaged in a wide range of civil engineering projects and also developed a soils stabilisation and remediation activity.

Hargreaves Services plc acquired the company in January 2016 and has re-focused activities towards Blackwell’s traditional skill set of major earthworks. In 2017 the company began work on a £50 million scheme to widen the A14 near Cambridge and has recently been appointed into a strategic partnership to develop the earthworks programme for two significant sections of HS2.

Historically Blackwell were involved in flagship projects such as the Olympic Park, Cross-Rail, Heathrow Terminal 5, and that track record now looks set to be perpetuated in to the future.
