The combination of the Colcrete Colloidal Grout Mixer with a Colmono Grout Pump into a self-cntained grouting unit, makes a very versatile and efficient piece of equipment. Each machine incorporates mixers and pumps of matched capacity which together with an agitated storage tank enable virtually continuous operation once work has commenced.
 The unique mixing action allows rapid mixing and pumping of grouts containing sand, up to a sand/cement ratio of 4:1 and neat cement grouts with water/cement ratios as low as 0.36:1 without additives, or lower with plasticisers or superplasticisers. The mixers are also very efficient at mixing bentonite and other clay products as the process accelerate hydration and makes a more stable product.
The range of mixers as detailed below cater for outputs from 1.5 to 8 cubic metres per hour as batch mixers, dependent upon mix design and material feed rated. Alternativepump rates can be specified if required.
