Advanced Investigation Systems uses the Hilti DD200 diamond coring
system, the latest in diamond coring technology, combined with
conventional or vacuum attachment mechanisms.

25mm to 400mm Diameter Cores
• mass concrete, reinforced concrete, brickwork, block work and    bituminous macadam coring
• coring of slabs and hard standing prior to ground investigation
• coring of road surfaces to determine construction thickness
• compressive strength testing of recovered cores

Horizontal Coring
• investigation of retaining wall construction (thicknesses in excess of    2m cored)
• stitch drilling for large / variable shaped holes
• cored holes for ducting / air conditioning / plumbing

Inclined Coring
• investigation of foundations
• drainage & ducting
• precise and accurate, together with an infinitely variable setup angle
