In 2023 Quarry Mining established ADA by way of de-merger to a standalone ADA Hardrock business.

A subsidiary of Quarry Mining & Construction Equipment, ADA can draw on the expertise and product range of the extended business to meet all the customer drilling and grouting needs within their one-stop shop.

TEI and Chemgrout products go hand in hand for the drilling and installation works for rock anchors, soil nails and stabilisation works to easily accommodate hard to reach high, low and tight drilling positions. The Chemgrout grout mixing plant range covers Paddle and Colloidal Mixing equipment as well as grout pumps, agitators, all their associated accessories and other specialty equipment.

Chemgrout plant and equipment brings safe, cost-efficient solutions to projects requiring anchors, cables, high pressure spraying works and other applications to soil and rock. TEI are your specialist leading manufacturer of excavator drill attachments, rock drill components and limited access drill rigs. Located in Beresfield in the Hunter Valley, the ADA workshop is set up to design, commission, test and fabricate custom made hitches, bracketry and other components to adapt to your existing equipment.
