The group, which until June 2010 comprised Ground Control in England and Moray Landscapes in Scotland, won contracts worth £24.8m in the financial year to April 2010 and turnover rose to around £32m during the 2010-11 financial year.
The acquisition of Wales-based firm Vale Contract Services in June last year pushed the figure up a further £7m to £39m.
Ground Control managing director Simon Morrish said the firm won many new maintenance contracts last year, including additional work for supermarket chain Asda and various utilities firms. It also won back a contract with Tesco - a deal that it had lost to competitor the Mitie Group in 2008.
Morrish said although the economic climate was making business difficult for many in the sector it had not harmed the firm.
