Manhole covers

The ever-increasing traffic density and the loading requirements of public streets have led to a growing demand for improved quality of manhole covers. Due to the rise of steel prices over the last years, together with high risk of theft, steel is no longer a viable solution for manhole covers. After a long and intensive research, the marmox Co., ISO 9001 certified, has developed an innovative product for manhole covers. This product is based on a newly developed high strength reinforced acrylic concrete.
