THE RIGHTREINFORCEMENT.THE SELF DRILLINGSYSTEM.Our Minova MAI Self Drilling System provide you with the highest qualityand support where you need it the most.Our Self Drilling System provides you with the highest quality and supportwhere you need it the most.SUPPORT WHERE YOU NEED ITFLEXIBLE SOLUTIONQUALITY ENGINEERINGMinova offers a wide range of high-performanceground support and consolidation productsand services as well as an extensive range ofgeotechnical solutions for applications in slopestabilisation, ground engineering, tunnelling, miningand rehabilitation.Our offer includes reinforcement solutions forunstable ground conditions such as sand, gravel, silt,clay and soft to medium hard and fractured rock.The system features a hollow bars, which are usedas a drill strings for drilling either with water flush,air flush or cement grout flush.Our Self Drilling System provides an efficient andcost-effective reinforcement solution.The hollow bars are fitted with a left-hand or righthand R-thread or T-thread for easy extension andconnection to conventional rock drilling equipment.The hollow bars are manufactured from seamless orwelded steel tubes.INNOVATING PERFORMANCEOur products can be used both as Self Drilling Soiland Rock Nails (SRN) or as Self Drilling Micropiles(MIP).Our know-how is the result of over 135 years ofexperience in the production and global supplyof geotechnical products and services, providingcustomized solutions tailored to meet the needs ofour clients.Product lines with and without technical approvalsare available.The Sellf Drilling System products are manufacturedby Minova MAI GmbH in Austria to meet the highestindustrial standards and to provide a quality productthat helps you to be safe.The production facility is certified according to ISO9001, ISO 14001 and ISO 45001.at least one end to compensate for deviations of theborehole angle with respect to the plate surface.The domed or flat plates feature a chamfered boreto ensure firm seating of the nut.All system components are rigorously testedaccording to stringent factory standards and ISO9001 to ensure that the specifications are met.The sacrificial drill bits significantly enhance theproductivity of the installation process.The R-thread according to ISO standards and theT-thread according to factory standard are formedin a cold rolling process. The hollow bars can beextended using couplers.In order to improve performance and costeffectiveness, project data are being collected fromaround the world.Our patented standard couplers ensure a safeconnection of the hollow bars to optimally transferthe impact energy from the drill hammer to the drillbit.Continuous optimisation of our drill bits is a primaryconcern to further improve the penetration rateand bit quality while at the same time reducingmanufacturing costs.A sealing rings in the centre stop minimise flushspillage during drilling.For an improved corrosion resistance, Self DrillingSystem components are either hot dip galvanized orfitted with a TwinCoat coating (hot-dip galvanizationwith an additional dual epoxy coating).The nuts are manufactured with a spherical cap onNutHollow bar / boltPlateLegal disclaimer:This product catalogue replaces and supersedes all prior catalogues.

SELF DRILLINGSOIL AND ROCKNAILS.Our Self Drilling Soil and Rock Nails (SRN) consist of a self-drilling hollowbar with a rolled continuous thread as load-bearing element embeddedwithin a grout body.SUPPORT WHERE YOU NEED ITIn underground applications, SRNs are predominantlyused for forepoling, spiling, face bolting and radialbolting.The SRNs are predominantly subjected to tensilestress, but may also be subjected to bending andshear loads.Our SRNs provide ideal solutions for weak, unstableor cracked ground conditions. SRNs are typicallygrouted along their entire length.In geotechnical engineering, they are used tostabilise natural or artificial slopes or to supportstructures e.g. retaining walls.SELF DRILLINGMICROPILES.Our Self Drilling Micropiles (MIP) consist of a self-drilling hollow bar with arolled continuous thread as load-bearing element that is embedded withina grout body.Micropiles are small diameter grouted piles (typicallyless than 300 mm in diameter) transferringcompressive, tensile or alternating loads into thesurrounding ground. They may also be subjected tobuckling loads in particular in soft ground.Self Drilling Micropiles are typically installed viasimultaneous drilling and grouting using cementgrout as the flushing medium.Particularly in cohesionless or unstable groundconditions e.g. sand, clay or gravel, this is the fastestand most efficient installation method for micropilesystems.Dependant on the ground conditions, Self DrillingMicropiles are designed either as end-bearing orfriction piles.Compared to other methods, smaller drillingequipment can be used, making Self DrillingMicropiles ideally suited for projects with limitedaccess, confined spaces or low headroom conditions.The main areas of application include: Foundation of new structuresTo further stabilise the surface of the slope or rock,various support systems e.g. flexible reinforcingmeshes or geotextiles may be installed that are heldin place by the head plates of the nails.

MICROPILES. Our Self Drilling Micropiles (MIP) consist of a self-drilling hollow bar with a rolled continuous thread as load-bearing element that is embedded within a grout body. Micropiles are small diameter grouted piles (typically less than 300 mm in diameter) transferring compressive, tensile or alternating loads into the surrounding ground.
