Designed primarily for the mixing and pumping of Bentonite and Polymers used as lubricants for Microtunnel and Pipejack construction, the Colcrete range of Microtunnel Lubrication Units (MLU’s) offer complete systems including mixers, storage tanks and injection pumps to meet a variety of requirements. They all incorporate the well-proven Colcrete Colloidal Mixer, which produces a very stable product, which resists water separation and retains its lubrication properties for longer when injected. A variety of pumps can be fitted, usually based upon well-proven grout pumps such as the Mocol and Minicol ranges.
Other combinations of mixers and pumps can be incorporated to meet most requirements.
