Anchor Piles
Ground Anchoring & Excavation Support Specialists
Jalmala Boring Works provides permanent and temporary ground anchor systems for diaphragm wall support, retaining walls, deep excavations, basements, and slope stabilization. Our high-capacity anchor piles are drilled, grouted, tested, and stressed to transfer lateral loads into stable ground, ensuring maximum structural stability, minimal wall movement, and safe excavation for commercial, industrial, infrastructure, and metro projects.
Ground Anchor(Tieback) Construction Process
A detailed step-by-step guide of how Jalmala Boring Works installs high-capacity Ground Anchors / Tieback Anchors for deep excavation support.
Survey, Setting Out & Anchor Positioning
Survey, marking, and positioning of anchors with precise inclination and coordinates.
- Survey and mark anchor locations as per approved drawings
- Determine anchor inclination, spacing, depth, and capacity
- Set up Hydraulic Anchor Drilling Rig
- Verify wall levels and drilling coordinates
- Ensure safe working platform and access
Anchor Hole Drilling
Drilling of inclined boreholes using hydraulic anchor rig.
- Drill inclined boreholes through diaphragm wall or retaining structure
- Use Hydraulic Anchor Rig with rotary/percussion system
- Drill to required length and stable strata
- Monitor drilling angle, depth, and diameter
- Clean boreholes using compressed air or water flushing
Anchor Tendon Installation
Insertion of prestressed strands or bars with corrosion protection.
- Insert prestressed steel strands or threaded anchor bars
- Install centralizers, sheathing, and corrosion protection
- Ensure proper free length and bonded length
- Accurate positioning within the borehole
- Pre-grouting inspection and approval
Grouting Operations
High-pressure grouting to bond the anchor tendon with surrounding ground.
- Inject cement grout or chemical from bottom to top
- Create strong bond between tendon and soil/rock
- Fill all voids and ensure complete encapsulation
- Maintain specified grout pressure and quality
- Allow grout to achieve required strength
Anchor Stressing & Lock-Off
Stressing of anchors to design load and lock-off.
- Install anchor heads, bearing plates, and wedges
- Test anchors using hydraulic jacks
- Stress anchors to the required design load
- Lock-off at approved working load
- Record elongation and test results
Quality Control & Excavation Support
Testing, monitoring, and long-term performance verification.
- Verify performance through proof and lift-off tests
- Monitor wall movement and anchor loads
- Install additional levels as excavation progresses
- Complete testing records and documentation
- Provide continuous lateral support to deep excavations

Anchor Pile Services in India – Built for Tension, Uplift & Lateral Loads
Most pile foundations are designed to carry downward load — the weight of a building pressed into the ground. But a growing class of structures needs piles that work the other way: piles that resist uplift, tension, and lateral forces. That is what anchor pile services are for. Jalmala Boring Works brings 60+ years of deep foundation expertise to every anchor pile project we execute across India — from transmission towers under wind load, to retaining walls resisting soil pressure, to basements fighting groundwater uplift.
Anchor Piles vs Regular Pile Foundations
The critical difference is direction of force. Regular pile foundations carry compression — they support buildings by transferring weight into deeper, stronger soil or rock. Anchor piles are designed for tension, uplift, and lateral loads — they resist the forces that try to lift, tip, or slide a structure. This changes the design calculation (IS 2911 Part 4 tension capacity), the pile detailing (reinforcement extends to the pile head for anchoring), the installation method (often inclined or raked), and the load testing procedure (pull-out test instead of downward load test). A piling contractor who understands only compression piles cannot execute anchor pile services correctly.
Applications of Anchor Piles in India
Anchor pile services are used wherever a structure must resist uplift or lateral forces. The most common applications we handle across India include: transmission towers (resisting wind-induced overturning), retaining walls (resisting soil and water pressure), slope stability projects (preventing landslides), basements in high-water-table areas (resisting buoyancy uplift), marine structures such as jetties and wharves (resisting wave and tidal loads), and wind turbine foundations (resisting overturning moments from rotor loads). Each application requires a specific anchor pile design — there is no one-size-fits-all.
Types of Anchor Piles We Execute
Our anchor pile services cover three primary types. Vertical anchor piles are installed straight down and resist uplift through shaft friction. Inclined (raked) anchor piles are installed at an angle to provide combined uplift and lateral resistance — commonly used in transmission towers and retaining wall tiebacks. Under-reamed anchor piles have an enlarged bulb at the base to increase uplift capacity in expansive soils like black cotton soil. We also deliver combined anchor pile + ground anchor systems where both are used together for maximum efficiency.
Anchor Pile Services Across India
Jalmala Boring Works delivers anchor pile services across 20+ Indian states. In Gujarat, we serve Ahmedabad, Surat, Vadodara, and Rajkot from our Sarkhej headquarters. In Maharashtra, we execute anchor pile projects in Mumbai, Navi Mumbai, Thane, and Pune. In Delhi NCR, we cover Delhi, Noida, Gurugram, Ghaziabad, and Faridabad. We also serve Tamil Nadu (Chennai, Sriperumbudur), Karnataka (Bangalore, Whitefield), Telangana (Hyderabad, HITEC City), and West Bengal (Kolkata, Salt Lake). No matter where your anchor pile project is located in India, we can mobilize quickly.
Quality, Testing, and Safety on Every Anchor Pile Project
Every anchor pile project we deliver follows ISO 9001:2015 certified processes — including geotechnical review, tension capacity calculation per IS 2911, pile detailing review, installation supervision, and pull-out load testing per IS 2911 Part 4. Our zero trench collapse record is a direct result of disciplined bentonite management, casing, and trained site teams. Anchor piles require more precision than regular piles — the tension capacity is unforgiving of installation errors — so we apply stricter quality control on every anchor pile installation.
Why Choose Jalmala Boring Works for Anchor Pile Services
Three things set us apart from other anchor pile contractors in India. First, our experience — since 1962, we have executed deep foundation projects across every major soil condition in India, including the specialized uplift and lateral load cases anchor piles require. Second, our equipment — a fleet of modern SANY hydraulic piling rigs that can handle inclined installation, large diameters, and deep toe levels with precision. Third, our documented processes — every anchor pile is backed by a design review, quality plan, and load test report that you can verify.
