ATLAS RESISTANCEPier FoundationSystems
Foundation Repair Systemsfor Civil Construction Applications:Residential, Commercial, IndustrialAtlas Resistance Piers have been used to restore and/or stabilize homes andcommercial structures that had settled due to a wide variety of soil problems.Foundation settlement and movement can becaused by building on expansive clay, compressibleor improperly compacted fill soils, or impropermaintenance around foundations. Whatever the cause,settlement can destroy the value of structures andrender them unsafe.For sample specs,technical library,case histories anddistributors, go towww.atlassys.comInstallation by smoothhydraulic pressureextends pier to reachcompetent end-bearingsoil stratum.Properly installed, Atlas Resistance Piers can preventsettlement, stabilize foundations and restore settled structures nearly totheir original positions, often closing structural defects such as cracks anddeformities caused by the the settlement. Because the solution is bothpermanent and economically attractive, thestructures retain or recover their value.Cost-effective rapid piersfit your job requirementsTrue end-bearing Atlas Resistance Piers aresold and installed only by contractors trainedby Atlas and authorized to recommend andprovide appropriate solutions to a widerange of soil problems.Design professionals may request a Chance Civil Construction Technical Design Manualon CD from their Distributor or TerritoryManager listed on our web sites: www.atlassys.com or www.abchance.com.Verifiable factor of safety achievedon each pier as installed Reach competent soil below active zone Extendable in 31/2-ft. sections No excavation or spoils to remove Loads may be immediately applied Installs in limited access Installs in any weather conditionPier Bracket Systems Applications*DesignUnder Continuous Plate Pre-Drilled Helical TieCapacity Dia.

Atlas Resistance PiersAtlas Resistance Pier & Helical Tieback Combo For lateral support needed in conjunction with Atlas Resistance PierWhere site conditions and load requirements warrant, this system combines Chance helical tieback anchorswith Atlas Resistance Piers. The helical anchors contribute lateral support to the piers providing verticalsupport. This unique combination forms a fast, effective solution for challenges beyond the capabilities ofother systems.Components for a single unit include:Concrete footing Atlas Resistance Modified Pier and Bracket Chance Helical Tieback Anchor Bearing Plate Bevel Washer All-Thread Rebar and Nut Square Shaft-to-Threaded Bar Transition CouplingFoundationstem wallAtlas Resistance Two-PieceModified Pier BracketChance Helical Tieback AnchorLead Section and ExtensionTransition couplingAll-threadrebarand nutBevelwasherBearingplateTop pierplatformPier pipesectionsTypical application —Atlas Resistance 2-PieceModified Pier and Bracket withintegrated Chance HelicalTieback AnchorFrictionreductioncollar Typic al A pplic ation U sing A tlas Re sist anc e 2-P iece M odifi ed P iers*Pier DesignCapacity0 - 35 kip0 - 45.5 kip0 - 55 kipPier and Tieback Combo Bracket Systems w ith Integr ated C hanc e Hel ic al Tieba ck An c hors.Atlas Resistance Modified PiersChance Helical Tieback Anchors2 8" Pier Diameter, reinforced top section31 2" Pier Diameter, reinforced top section4" Pier Diameter, reinforced top section11 4" RC Square Shaft SS125 Series11 2" RC Square Shaft SS5 and SS150 Series11 2" RC Square Shaft SS5 and SS150 Series13 4" RC Square Shaft SS175 Series*Based on a Safety Factor of 2 for pier ultimate mechanical strength.77
