About Us

GM. Tumbler was established in 2011 to provide replacement Concrete / Cement Mixer Drums / Bottles and Spare Parts to Readymix Concrete Manufacturers throughout Ireland and the UK. We can build replacement drums for all makes.

We use wear resistant steel on the outer skins, blades and tips. With our unique mixer blade arrangement our mixer drums have no bother mixing and discharging semi-dry concrete or special mortar mixes.
