Atlas Copco launches new micropiling system


As the global redevelopment of urban areas continues, the need for a cost-efficient method to stabilize structures in sensitive areas is increasing. Micropiling is growing in popularity as a method to reduce the effects of settlement in both existing and new constructions.

Micropiling with MAI SDA T111

Atlas Copco is now introducing the latest technology in micropiling – the MAI SDA T111, a self-drilling micropile that drills and reinforces the hole in one single process.
The MAI SDA T111 consists of a 111 mm (4.37") diameter hollow threaded rod with a sacrificial drill bit. Thanks to extension couplings, the system offers a flexibility to easily adjust the rod length to the site requirements. This is especially useful if piling has to be performed in a confined workspace, for example with limited head room which is often the case in underpinning.

MAI SDA T111 self-drilling micropiles can be installed with most tophammer rigs, for example the compact Atlas Copco Mustang rigs. With only light equipment needed for installation of the SDA micropiles and with no need to use large concrete mixing trucks, less impact is made on the surrounding area in terms of exhaust fumes, noise pollution and vibrations.
“The T111 is primarily aimed at unconsolidated soil formations such as sand and gravel, and is ideal for difficult micropiling”, says Steve Greer, Vice President Geotechnical business at Atlas Copco. “Thanks to a selection of drill bits, the T111 system can drill through anything from sandstone to hard rock.”
