Why Are D-Walls Becoming Extremely Popular with Construction Companies in India?

Diaphragm walls for top-down construction and deep basements have now become commonplace in the industry, and among construction companies in India. But how did D-Wall construction (another name for diaphragm walls) become a popular choice with civil engineers who are now confident to build towering superstructures with basements as deep as 5 levels?

Let us begin by understanding what a diaphragm wall is, how it is different from other traditional methods of ground engineering like Piling, and what makes it a desirable choice for deep basement construction.

What is a diaphragm wall?

Reinforced concrete walls built in the ground to provide support to the structure to be built above, and act as walls for the deep basement space to be built later, are known as diaphragm walls. They act as the cut-off walls for the excavated area of the site, provide a strong foundation to the surface and enclose the structure.

Piling – The traditional method of deep foundation construction

Piling is one of the oldest methods of building foundational bases for under-construction structures to transfer and manage the structural load on a deeper level. They are long, cylindrical structures that are made of either concrete, wood or steel.

There are two types of pile foundations used in building strong bases

1. End-bearing piles, that can transmit weight load directly to the deeper, stronger soil or the rock base of the site.

2. Friction piles, which transfers the load of the building to the soil across the full height of the pile, by friction.

Piling, a traditional method, is used when 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.

While a diaphragm wall is constructed by excavating a narrow trench with a thickness ranging between 300 mm to 1200 mm, as deep as 45 metres underneath. It actually does the exact same job, and moreover, offers to act as a retaining wall for the basement, making the foundation stronger.

Yet, what makes construction companies in India choose diaphragm walls for basements?

Lower steel consumption

The cage walls made for diaphragm wall construction require lesser steel bars compared to constructing and inserting piles into the ground below. And in scenarios of unstable soil on the site, an additional casing is required on the piles, which may add an extra cost to the materials consumed.

What Makes HIPL the Best Diaphragm Wall Construction Company in India

With a legacy of over 300 projects, Heritage Infraspace has secured a position among the top diaphragm wall construction companies in India. And as the leading name in diaphragm wall design and construction, it has always upheld the principles of value-added engineering in every project.

Heritage Infraspace Private Limited believes that every strong and durable foundation laid today shapes a more reliable future. With this in mind, it ensures top notch safety and quality deep basement construction that is completed well before the ending period.

Take a look into the key factors that make HIPL the best diaphragm wall construction company in India.

What makes HIPL a notch above the top diaphragm wall construction companies?

The common link between the Central Secretariat, DLF Downtown, Delhi Metro and many other significant projects is their sturdy and durable foundation, made by the top diaphragm construction company in India.

They, hence become the living specimen of HIPL’s construction principles which are as below:

A promise of safety for all

Being among the top construction companies for deep basements, HIPL ensures safety for all at two levels. First is the on-site safety of the qualified engineers, working staff members and supervisors. Each site has qualified safety managers and officers that make sure all safety measures are met and safety regulations are duly followed.

Secondly, HIPL ensures that the safety of upcoming residents and office owners is never compromised by employing advanced machinery and quality materials during the construction of deep basement diaphragm walls.

Every person that visits the site, whether the workers or the client is given safety gear including a helmet, gloves, safety boots and jacket. For those welding the iron mesh, face shields and glasses are provided.

However, what takes HIPL a notch above other diaphragm wall construction companies in India is the daily reminder drill of safety instructions done by every individual present on the site.

Uncompromised Construction Quality

All long-lasting construction marvels have a strong base built with quality materials. Hence Heritage Infraspace follows rigorous standards of quality, from appointing a highly qualified ground team to using the best materials for the construction of the diaphragm walls.

Being among the top construction companies for deep basement diaphragm walls, HIPL stepped in to fill the quality gap in the material used in construction sites across India. Hence it started its very own RMC plant to enable the high reach of assured quality concrete for all types of construction activities.

The materials used on the site go through multiple tests to get the optimised properties. All stages of construction are completed under expert guidance that verifies even the tiniest details from aligning the metal cage to the centre, to using GI (Galvanised Iron) wire for anti-corrosion benefits.

Why do Deep Basements need Diaphragm Wall Construction?

Residential complexes with multiple apartment buildings and commercial complexes with hundreds of offices and shops are now a part of the landscape of every growing city in India. And these new-age buildings have multistoried basements built deep into the ground for various purposes. These deep basements require diaphragm wall construction to ensure that they have a formidable foundation.

Read on to know about the advantages of concrete diaphragm wall construction for deep basements in all forms of modern buildings.

What is diaphragm wall construction?

Diaphragm walls are reinforced concrete walls constructed for deep basements in the ground. An under-slurry technique involving the excavation of a narrow trench is used for this and walls with thicknesses ranging between 300 mm to 1200 mm can be formed as deep as 45 metres underneath for the next stage of excavation to be conducted.

Advantages of diaphragm wall construction

Build basements of significant depths

A growing population means taller and bigger residential and commercial complexes, which in turn require equivalent parking space. Basement parking lots are an ideal solution to this problem. Earlier, the deep basements would be built up to 3 floors through piling methodology. But with diaphragm wall construction technology, developers are now building basements as deep as 5 levels.

This is because piling would increase the number of joints, might have alignment issues and risk having leakages, but deep basement concrete diaphragm walls serve as a strong foundation as well as protective walls to these basements.

And more space for parking means these commercial and residential properties will be in higher demand compared to the ones with lesser or no parking space.

Construction produces low vibration levels

Another of the great advantages of diaphragm walls is that their construction causes very less vibration to the land and hence minimises the risk of damage to nearby structures. Open excavation involves using heavy machinery like drilling machines, earth movers, etc, which may weaken the foundation of the overall soil on the site and put neighboring buildings at risk of irreparable or hefty damages.

HIPL’s fleet of machines has the best hydraulic rigs manufactured by Casagrande, imported from Italy. This is one of the many things that makes HIPL one of the best diaphragm wall construction companies in India.

Concrete diaphragm walls can act as water barriers too

The water table of the soil in various regions of India varies from moderate to very high. And as the construction gets deeper, the water pressure can increase and cause damage to the basement structure. Concrete diaphragm walls can act as good barriers to water pressure, thanks to the water bars and crystalline compound used in the mix.
