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

Cement Prices Likely to Rise Rs. 10-15 per Bag from Mid-October

Input costs and steady demand may drive cement price increases

Cement manufacturers in India are likely to raise prices by Rs. 10-15 per bag from mid-October, as they seek to offset persistent increases in power and fuel costs. Emkay Research said its channel checks indicated a high probability of an increase from October 12, supported by the start of the busy construction season and favourable demand-supply conditions.

The sector had implemented similar rate adjustments of Rs. 10-15 per bag during the first quarter, but the increases were insufficient to cover higher operating costs. Prices also softened during July and August because of the monsoon, widening the gap between realisations and input expenses. Delayed plant expansion programmes have pushed clinker utilisation rates towards 79 per cent by FY28, helping to balance market fundamentals.

Emkay Research said steady volume offtake was supporting cement consumption, with non-trade demand driving activity across regional markets. Industry volumes are expected to grow by 7-8 per cent year on year during the first half of FY27, while demand momentum is projected to remain firm over the following 18 months. The outlook includes the busy construction season in the second half of FY27 and infrastructure activity linked to general elections in the first half of calendar year 2029.

The brokerage expects overall cement demand to record a compound annual growth rate of about 7 per cent between FY26 and FY28. However, elevated operating expenses are likely to continue weighing on profitability. Input costs have risen by Rs. 300-400 per t over the past six to seven months, with the full impact expected to become visible in second-quarter earnings and remain persistent through the second half of FY27.

Spot prices for petcoke and imported coal are approximately 20 per cent and 16 per cent above their second-quarter averages, at USD 175 per t and USD 150 per t, respectively. Packing costs have also increased, with polypropylene granule prices rising above Rs. 135 per kg. Emkay Research estimated that second-quarter earnings could decline by Rs. 200-250 per t sequentially because of higher fuel bills and negative operating leverage, and said the sector requires sustained price increases of about Rs. 10 per bag to offset cost inflation.

Nuvoco Vistas Corporation Limited is celebrating a decade of operations under the theme ‘Dus Saal Bemisaal’, highlighting its expansion in India’s building materials sector. The company has grown from a single cement manufacturing facility into a diversified organisation operating across cement, ready-mix concrete (RMC) and modern building materials.

The company’s journey began in 2014 when its parent, Nirma Group, commissioned a 2 million metric tonnes per annum (MMTPA) greenfield cement plant at Nimbol, Rajasthan. A major milestone followed in October 2016 with the acquisition of Lafarge India, significantly expanding its manufacturing footprint.

Nuvoco strengthened its market presence through the acquisition of Emami Cement, now NU Vista Limited, in 2020, followed by its public listing in 2021. In April 2025, the company added Vadraj Cement to its portfolio, strengthening its presence in western India.

Nuvoco has an operating cement capacity of 27 MMTPA and 14 manufacturing units, including the Kutch and Sachana facilities in Gujarat, which are in advanced stages of completion. It also operates 58 ready-mix concrete plants across India and offers a range of modern building materials.

The company aims to increase its cement capacity to 35 MMTPA by FY2027-28, representing approximately 15-fold growth over the decade.

Reflecting on the milestone, Hiren Patel, Chairman, Nuvoco Vistas Corporation Limited, said, “From our beginnings at Nimbol to the organisation we are today, every milestone has added a new chapter to Nuvoco’s journey and strengthened our belief in building for the long term.”

The company continues to focus on capacity expansion, operational efficiency, innovation and sustainability while strengthening its position in India’s construction materials market.

Jammu and Kashmir government has notified the City Gas Distribution (CGD) Policy, 2026, following its approval by the Council of Ministers headed by Chief Minister Omar Abdullah. The policy sets out a phased framework for expanding Piped Natural Gas (PNG) and Compressed Natural Gas (CNG) access for households, businesses, industries and the transport sector across the Union Territory.

CGD networks will be expanded in phases across all 20 districts, with the aim of bringing reliable natural gas closer to consumers and supporting a gradual shift from conventional fuels. The government said the policy is designed to improve energy access while creating an investor-friendly and time-bound environment for gas distribution projects.

The policy provides for single-window and time-bound clearances, streamlined procedures for setting up CNG stations and standardised norms for the Right of Way. These measures are intended to reduce procedural delays, simplify project implementation and facilitate investment in natural gas infrastructure.

It also prioritises gas connectivity for major industrial estates, including those in Kathua, Samba and Pulwama. Improved access to natural gas is expected to support industrial activity, enhance energy efficiency and help businesses manage fuel costs, while strengthening their competitiveness and encouraging investment in the clean-energy sector.

The policy is also expected to create opportunities for local employment, apprenticeships and skill development in the construction, operation and maintenance of gas distribution networks and related services. Abdullah described the measure as an important step towards cleaner growth, sustainable development and a modern energy ecosystem in Jammu and Kashmir, saying it would expand reliable energy access and support industry and investment.
