Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.

High-capacity, small-diameter pile foundations and shoring solutions engineered for restricted access and challenging ground conditions across South India.
Micro piles are small-diameter (typically 100–300 mm), high-capacity deep foundation elements drilled into the ground and grouted under pressure to transfer structural loads through friction and end bearing into competent strata. They are ideal where access is restricted, headroom is limited, or conventional piling rigs cannot be mobilised, providing a stable, load-bearing foundation system with minimal vibration and disturbance to adjacent structures.
Shoring systems paired with micro piles provide temporary or permanent lateral support to excavation faces and adjacent foundations during construction. Combining drilled micro pile elements with bracing, walers, and tie-backs creates a rigid support structure that resists earth pressure, surcharge, and groundwater forces — enabling safe, deep excavation even in dense urban environments.
At PJ Construction, our crews operate compact micro-piling rigs and grouting plants suited for confined basements, underpinning works, and sites with low headroom — delivering precision and structural reliability on every installation. Each pile is designed against geotechnical capacity requirements and verified through load testing before handover.
We bring engineering precision, compact specialist rigs, and a proven safety record to every micro pile and shoring project across South India.
We own and operate low-headroom micro-piling rigs and grout pumps — enabling work inside basements and confined sites without subcontracting delays.
Every micro pile layout is designed by qualified structural and geotechnical engineers based on load capacity and settlement analysis — not generic spacing assumptions.
Successfully executed micro pile and shoring contracts across Tamil Nadu, Karnataka, Andhra Pradesh, and Kerala — including sensitive underpinning near live structures.
Static and dynamic load tests, grout quality checks, and third-party QA inspections are standard — your foundation is backed by documented performance data.
Our structured, stage-by-stage approach ensures each pile is installed and verified before structural loads are transferred — eliminating risk of differential settlement and complying with IS 14893 guidelines for micro piling.
Soil borings, SPT tests, and lab analysis establish bearing capacity and skin friction values. Pile diameter, length, grout pressure, and reinforcement are designed against the structural load demand and factor of safety requirements.
Compact micro-piling rigs are mobilised and positioned within available headroom and access constraints. Working platforms are levelled and utilities are located before drilling begins.
Holes are drilled to design depth using rotary or percussive methods, with temporary casing inserted in unstable strata to maintain borehole stability during installation.
Steel reinforcement cages or bars are lowered into the borehole and pressure grouted in stages, ensuring full-length bond between the pile shaft and surrounding ground for maximum load transfer.
Where shoring is required, piles are tied into waler beams, struts, or tie-back anchors to form a rigid lateral support system resisting excavation-induced earth pressures.
Selected piles undergo static or dynamic load tests to verify design capacity. Settlement markers and monitoring instruments track performance throughout the construction sequence.
Micro pile foundations and shoring systems are applied wherever access is restricted, loads are high, or adjacent structures must be protected during construction.
Building Underpinning Strengthening existing foundations affected by additional loads, settlement, or adjacent excavation — without disturbing the structure above.
Low-Headroom Basement Works Foundation installation inside existing basements or under low ceilings where conventional piling rigs cannot operate.
Bridge & Culvert Foundations High-capacity foundation support for bridge abutments and culverts in constrained right-of-way conditions.
Heritage & Sensitive Structure Support Low-vibration foundation reinforcement near heritage buildings or sensitive structures requiring minimal disturbance.
Slope & Hillside Foundations Anchoring structures into stable strata on sloping or unstable terrain where shallow foundations are inadequate.
Temporary Excavation Shoring Lateral support systems for deep excavations adjacent to existing buildings, roads, or utilities in dense urban areas.
