    Does anyone have any experience of core drilling into Bison Solid Composite Flooring. I think that they are re-inforced with steel rods in a lattice arrangement but I'm not sure. Any help would be much appreciated. Thankyou

    Have limited experience on this practically , but have witnesed many specialist core drilling firms coring holes for pipework.
    On bison slabs I have only ever seen Hilti equipment being used ie .Diamond core, always water cooled (I think the water also acts as a lubricant thus preventing sticking)Hilti diamond cores are also specified for the particular material involved. ie , abrasive,highly abrasive non abrasive, steel reinforced etc.

    Truthfully, you are not supposed to core drill penetrations through bison units since they are prestressed. If you go through the steel you will not be going through a reinforcing bar but going through a prestressing tendon.

    Can the services not go via a different route?
