TIEBACKS & MICROPILES
Drilled Solutions. Engineered for the Load.
Tieback anchoring and micropile foundation systems for earth retention, structural support, underpinning and challenging subsurface conditions.
TIEBACKS
Anchored earth retention systems
MICROPILES
High capacity drilled foundations
TESTING
Verification of design performance
Empire provides tieback and micropile installation for projects where access, loading, excavation geometry or subsurface conditions require a specialized foundation or anchoring solutions. Systems can be coordinated around project specific design requirements, installation criteria and testing programs. Solutions for Challenging Conditions
DRILLED FOUNDATION & ANCHORING
Compact Equipment
Drilled systems can be installed where conventional piledriving equipment or methods may not be practical.
Engineered Systems
Pile and anchor configuration can be coordinated with project loads, subsurface conditions and delegated design requirements.
Compact Equipment
Proof, verification and load testing can be incorporated as required to confirm installation and design criteria.
TIEBACK ANCHORS
Anchor The Wall. Maximize The Excavaton.
Tiebacks provide lateral support for sheet pile, soldier pile and other earth retention systems while keeping the excavation clear of internal bracing allowing a larger foot print when space is needed. Empire can install helical or drilled/grouted anchor systems based on the project design and subsurface conditions.
EARTH RETENTION ANCHORING
Design-Build Anchoring Solutions
Empire works with contractors and qualified engineering partners to develop practical, constructible tieback solutions for the projects retention system. Anchor type, spacing, inclination, capacity and testing requirements can be evaluated to provide a design or value eningeered approach that considers both performance and installation efficiency.
Soldier Pile & Lagging
Anchored support for deeper excavations where cantilever walls are not practical.
TIEBACK APPLICATONS
Basements and Below Grade Work
Maintain an open excavation while supporting adjacent grades and structures.
Water/Wastewater
Anchored retention for tanks, structure, piping and treatment plant improvements.
Sheet Pile Walls
Tieback support of temporary or permanent sheet pile retention systems.
Civil Infrastructure
Bridge, utility, roadway and other excavation support applications.
Remedial Support
Supplemental anchoring where existing retaining systems require additional resistance.
MICROPILES
High Capacity. Small Footprint.
Micropiles transfer structural loads through weak or variable soils into competent bearing strata using small diameter drilled and grouted elements reinforced with high strength steel. Their compact installation footprint makes them well suited for restricted access, underpinning and projects with difficult subsurface conditions.
SPECIALTY DEEP FOUNDATIONS
Adaptable To Difficult Sites and Subsurface Conditions.
Micropile systems can be configured around structural loading, casing requirements, reinforced, bond-zone geometry and subsurface conditions. Where delegated design is required, Empire can coordinate sealed foundations submittals, installation criteria and value engineers options through qualified engineering partners.
New Foundations
Deep foundation support where conventional driven piles or larger drilled shafts are not ideal.
Limited Access
Foundation installation inside existing strides or constrained work areas.
Structural Retrofits
Additional foundation capacity for expansion, renovations and increased loading.
Underpinning
Transfer or supplement loads beneath existing foundations with limited disturbance.
Variable Soils
Adaptable installation through fill, obstructions and changing subsurface profiles.
Uplift/Compression
Systems can be designed for project specific compression, tension and lateral demands.
Let’s Build The Right Foundation.
Empire can review the project requirements, installation conditions and testing criteria to help define the appropriate scope and begin coordination for delegated design where required.
