The Sutton Coldfield highways and drainage firm worked as a specialist subcontractor, approved by Birmingham City Council and Severn Trent Water.
RW Services was founded in 1979 and worked in and around the West Midlands.
The firm used to use its excess tarmac to fill pot holes in roads and paths in Sutton Park, Birmingham as an environmental gesture to benefit the community.
Mark Bowen of Birmingham MB Insolvency is handling the affairs of the firm.
