Piling contractors in india
Piling is a kind of deep foundation construction done to transfer and manage the structural load on a deeper level. The piles used in this type of construction are long cylindrical structures made of concrete, wood or steel, pushed into the ground to provide sturdy support to the structures built on it.
The 2 common types of pile foundations done by any piling company in India are End Bearing piles, one where the bottom of it rests on a strong surface by passing the weak and strong layer of soil and Friction piles, which transfers the load of the building to the soil across the full height of the pile, by friction.
Building pile foundations by hiring piling contractors in India is an ideal option when the water table is high and the soil layer on the surface is weaker for more than 2 meters, the structure above has heavy, concentrated loads and the spread footing won’t be able to bear the weight. So the building structure needs to bypass this layer and transfer the weight to the stronger base at depth.
Types of piling in India
The common types of piling methods used by any piling company in India in construction projects include bored piling, driven piling, micro piling and sheet piling. Bored piling involves drilling holes and filling them with concrete and reinforcement for large and deep foundations. Driven piling utilises prefabricated piles hammered or vibrated into the ground, suitable for cohesive and non-cohesive soils.
In Micro piling, the piling contractors use small-diameter piles for foundation support, often employed in limited-access areas or weak soil conditions, whereas in sheet piling they involve interlocking steel sheets to create retaining walls or stabilise slopes. These methods are employed to provide structural support in challenging soil conditions or transfer loads to stable layers
Benefits of piling in India
Piling in India has numerous benefits in construction. Firstly, piling if done by an experienced piling company in India provides a strong foundation system capable of withstanding challenging soil conditions, ensuring stability and durability. Secondly, piling allows construction in areas with high water tables by creating deep foundations that resist the upward pressure of groundwater.
Additionally, piling is effective in weak or loose soil, as it anchors structures to more stable layers, reducing the risk of settlement or failure.
Moreover, basement construction by piling contractors in India reduces the need for extensive excavation, saving time and cost and minimising environmental disruption. By utilising piling techniques, construction projects can proceed smoothly, even in areas with difficult soil conditions, resulting in safer and more reliable structures.
The process
- The first step is to conduct a thorough site investigation by a piling company in India to assess the soil conditions, groundwater levels and any potential obstructions.
- Based on the site investigation by piling contractors in India, an engineer will design the piling system.
- Bored cast-in-situ pile is constructed by digging a hole in the ground by a percussive or rotary method.
- Drilling of mud is done using a temporary or permanent casing.
- Drilling buckets are adapted for digging loose, cohesionless soil or soft clays below the water table.
- Once the piles are in place, reinforcement is inserted into the bored piles.
- Next, the construction is finalised by filling the hole with reinforced concrete.
- The newly poured concrete needs time to cure and gain strength.
- Pile load tests may be conducted to verify the capacity and performance of the piles.
- After curing and passing tests, excess pile length is trimmed and a pile cap/foundation slab is constructed to transfer the load onto the piles.
Solutions we provide
Precast Concrete Piles to bring extra strength. An experienced piling company would offer precast piles in different sizes and shapes as required by the construction project. These piles can be pre-stressed too. They provide several benefits too:
Strength and Durability: Precast concrete piles are manufactured under controlled conditions, ensuring high-quality concrete and reinforcement. This results in strong and durable piles that can withstand heavy loads and various soil conditions.
Customisation: Precast piles are available in different sizes and shapes, allowing for customisation based on the specific requirements of the construction project. This flexibility ensures that the piles can be tailored to meet the structural and geotechnical needs of the project.
Ease of Installation: Precast piles are delivered to the site ready for installation, which reduces on-site labor and construction time. This helps in speeding up the construction process and minimising disruptions for piling contractors.
We provide cast-in-situ concrete piles, with and without casing. A steel casing driven into the soil, with a mandrel placed inside and withdrawn later to be filled with concrete and they offer a different set of benefits.
Adaptability to Soil Conditions: Cast-in-situ concrete piles can be constructed to adapt to various soil conditions, making them suitable for a wide range of project sites. They can be installed in cohesive soils, granular soils and even in challenging soil conditions such as soft or loose soils.
Customisation: The size, length and shape of cast-in-situ concrete piles can be easily customised to meet the specific requirements of the project. This flexibility allows for optimised foundation design based on the load-bearing capacity, soil properties and structural design needs.
Load-Bearing Capacity: Cast-in-situ concrete piles can be designed to withstand heavy loads. They are particularly suitable for projects that require high load-bearing capacity, such as high-rise buildings, bridges and industrial structures.
Piling equipment and safety measurement
Piling equipment plays a crucial role in efficient and safe piling operations. Common types of equipment we use include piling rigs, vibro hammers, impact hammers and excavators/cranes. Safety measures are of utmost importance in piling operations and should be implemented by every piling company in India to mitigate risks.
Some of the key safety measures included us are proper training for operators workers and piling contractors in India we ensure the use of personal protective equipment (PPE), site preparation with clear markings and barriers, regular equipment inspections, assessing ground stability, fall protection measures, communication protocols and emergency preparedness. By following these measures, the risk of accidents and injuries can be minimised, ensuring a safe working environment.
Frequently Asked Question
Pile foundations offer many advantages, such as being well suited for sites with weak or compressible soils, being able to support structures in seismically active regions or areas with a high water table, being relatively easy to install and being able to support both new construction and existing structures.
Piling is used in construction to provide structural support by driving or drilling long columns, called piles, into the ground. It is necessary when the soil is weak, unstable, or prone to settlement, allowing the weight of the structure to be distributed over a larger area and reach more stable soil or rock layers.
The best soil for piling typically includes stiff clay, dense silt, or well-graded sandy soils. These soils offer good load-bearing capacity and stability, ensuring effective support for the structure. A geotechnical investigation by engineers and piling contractors is necessary to determine the most suitable soil conditions for piling.
They can be rectangular or circular in shape. Their diameter, or size, can vary from 12 to 16 inches. The length of the pile is usually 20 times the top width. They are usually designed for 15 to 20 tons.
