Vijay Shah, Managing Partner, India Precast, talks about the process of making precast concrete shapes, with a focus on the challenges that accompany the production.

Tell us about the process of casting concrete in shapes.
Precast concrete products are made through pouring either wet cast or dry cast concrete into moulds, which are then hardened and removed to be dispatched. These moulds could be from concrete posts, pillars, columns, slabs etc. This benefits the construction process as it can be difficult to manoeuvre or create the right shapes and sizes by pouring the concrete on site.

The process of making precast shapes involve:

Build a form. The inside of the form defines the shape that is being created. This form is then filled up with cement and is kept to dry and harden.
Clean the mould before adding cement to it. The mould should be lined with materials or chemicals that allow for the hardened concrete structure to retrieve from it.
Cement or concrete mix is then created to be poured into the moulds for setting. We use a variety of concrete grades like M25, M30, M35, M40, and M45 for this mix. The mould poured in cement is left alone for 24 hours to harden and removed once set.
Once set, a hard mould is either broken or the cast is retrieved from a soft mould by shaking, which is ready to be transported to the location of construction or building activity.

What are the standard sizes and shapes of precast made by your organisation?
Our organisation makes various types of precast elements like:

Solid load bearing floor slabs, load bearing walls, facades, sandwich wall panels and cladding panels
Floor and roof slabs, made from prestressed load bearing hollow concrete slab and ribbed slab. Floors or roofs are also made from half floor slab or semi-finished floor slab with
lattice girder.
Precast stair cases, balcony, toilet pods, lift shafts and water tanks
Prestressed lintel, frames, beams, column and double tee beam
Internal partition walls, made from light-weight hollow core wall panels instead of AAC blocks or bricks
Sandwich walls, beams, columns, I-Beam, tee beam, lintel, footings, boundary walls, retaining walls, fencing poles, U-drainage or trench, box culvert, jersey barriers, covers, paver blocks etc.

Explain the moulds used to make these shapes. Do you customise moulds?
Concrete moulds are moulds that are used to shape the concrete you are working with. The concrete will adopt the shape of the mould as it cures. Concrete moulds are used to give concrete its finishing shape. Moulds are of various types (refer table below). We customise the moulds as per requirements.

S. No. Mould type Uses

Conventional moulds Ribbed slabs, beams, window panels, box type units and special elements
Battery moulds Interior wall panels, shell elements, roof and floor slabs
Tilting moulds Exterior wall panels where special finishes are required on one face or for sandwich panels
Long line prestressing beds Double tees, ribbed slabs, piles and beams
Extrusion machine Roof slabs and hollow core slabs

The New Delhi Municipal Council has launched an intensive sanitation drive across Lutyens’ Delhi, aiming to raise cleanliness standards in the capital’s central precincts. The programme will combine enhanced manual sweeping with mechanised cleaning and systematic waste removal to cover parks, heritage precincts and prominent thoroughfares. Authorities described the initiative as a sustained effort to improve public hygiene and reduce environmental hazards while maintaining the area’s civic image.

Operational teams have been instructed to prioritise drain clearing and litter hotspots, with special attention to markets and transit nodes that attract heavy footfall. Coordination with city utilities and waste processing units will be stepped up to ensure timely collection and disposal, and supervisory rounds will monitor adherence to cleaning schedules. Officials also intend to use data-driven planning to deploy resources efficiently and to identify recurring problem areas.

The council plans to engage resident welfare associations and business stakeholders to foster community participation in maintaining cleanliness and to support behavioural change campaigns. Public communication will be amplified through notices and outreach to encourage responsible waste handling and to inform residents about collection timings and segregation norms. Enforcement measures for littering and unauthorised dumping will be reinforced as part of a broader strategy to deter violations and sustain cleanliness gains.

The move reflects a focus on urban sanitation that officials link to public health priorities and to the city administration’s commitment to maintaining civic amenities. Monitoring mechanisms will include regular reporting and inspections to review outcomes and to recalibrate operations where necessary, according to municipal sources. The council emphasised that continued community cooperation will be essential for the drive to deliver lasting improvements in the appearance and hygiene of the capital’s core areas.
