Piling & Foundation Engineering

Specialist Foundations

Engineering Strong Foundations for Every Structure

Foundations determine the strength, stability and service life of every structure. At Mulavarickal Group, we provide specialised piling and foundation engineering solutions for projects where precision, safety and reliability are critical.

Using modern hydraulic rotary piling equipment, experienced engineers and skilled operators, we execute foundation works across a wide range of soil and rock conditions. From commercial high-rises to railway infrastructure and industrial facilities, our objective is to deliver foundations that meet the highest engineering standards while maintaining productivity and project schedules.

Solutions

Our Foundation Solutions

We provide complete, end-to-end piling services using state-of-the-art hydraulic rotary drilling rigs.

Rotary Bored Cast-in-Situ Piles

Drilling deep pile boreholes in soil and rock using rotary rigs, followed by placement of reinforcement cages and tremie concreting.

Rock Socketed Piling

Precision drilling into hard rock strata and weathered rock using chisels and core barrels to transfer high vertical structural loads.

Large Diameter Piling

Execution of large diameter piles (1000mm to 1500mm+) to support high vertical loads and lateral movements of major infrastructure.

Bore Stability Systems

Use of bentonite mud slurry suspension systems and temporary casing installations to keep borehole walls stable in loose sands or high water table areas.

Reinforcement Cages

In-house fabrication, circular ring fixing, lifting, and vertical installation of heavy steel reinforcement cages into drilled bores.

Tremie Concreting

Underwater concrete placement using vertical modular tremie pipe sections, replacing slurry mud from the bottom up to ensure pile structural integrity.

Laterite and hard rock strata site excavation

Workflow

The Bored Piling Process

We execute piling using a systematic, quality-checked workflow to ensure absolute structural load-bearing reliability.

1

Survey & Point Fixing

Verification of exact pile coordinates using total station survey data and checking alignment offset before rig setting.

2

Drilling Bores

Rotary drilling to specific depths and bore diameters, using temporary casing or bentonite mud to keep bore walls stable.

3

Cage Lowering

Lifting and vertical installation of prefabricated cylindrical steel reinforcement cages inside the borehole using service cranes.

4

Concreting

Continuous concrete placement using tremie pipes. Slurry displacement is monitored until rich concrete surfaces are clear.

5

Pile Testing

Coordination of Pile Integrity Tests (PIT) and static load tests to verify pile structure density and load capacity.

✓

Documentation

Logging pile log sheets detailing socket depth, concrete volume, slurry density, and borehole logs for structural handover.

Quality Checks

Quality Control Inspections

Every foundation pile is executed under close supervisor monitoring. Our quality procedures include:

Verticality Checks: Ensured during rig positioning and drilling (must be < 1% deviation).
Bore Depth & Socket Logging: Constant measuring of rock chips to confirm socket depths inside granite.
Slurry Density Control: Monitoring bentonite marsh funnel viscosity (between 30 to 40 seconds) to prevent bore collapses.
Slump Check: Concrete slump maintained at 150mm to 200mm for high flow properties through tremie pipes.

Applications

Infrastructure Applications

Our piling services support key structures where subsoil capacity is weak:

High-Rise Commercial & Residential Complexes
Industrial Structures & Manufacturing Plants
Bridges, Flyovers, and Metro Rail Viaducts
Railway Station Foundations & Platform Extensions
Airport Terminal Buildings & Hangar Foundations
Marine Foundations & Coastal retaining structures
