Grouting – Resin Anchors
In 1993 Minova Australia completed the development and introduction of Lokset TOOSPEEDIE® resin capsules, the world’s first two speed resin capsule. A development that remains to be the most ground breaking evolution in resin bolting, the Lokset TOOSPEEDIE® eliminates the need to use multiple resin capsules to achieve pretensioning of fully encapsulated resin grouted rock bolts.
Lokset TOOSPEEDIE® capsules are available in multiple set time ratios, as designated by the product codes typically displayed below. Combinations of set times are possible using any of Minova’s resin mastic formulations.
