Effective communication is essential in precast detailing

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

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

Cement Prices To Hold Steady Amid Monsoon Slump

Centrum report says demand weakness will limit hikes

Published

Centrum, a financial services firm, has reported that cement prices are likely to remain largely unchanged in July as weak demand during the monsoon season constrains pricing power. The report noted that construction activity remained subdued in the first quarter of fiscal year 2027 owing to labour shortages and slower execution of government projects. While June showed some volume recovery driven by delayed monsoons and quarter end sales, dealers are cautious about sustaining any price increases.

The analysis suggested that seasonal slowdown related to monsoon will prolong demand and pricing challenges through the second quarter. Dealers saw most recent attempts at price hikes as protective measures rather than genuine shifts in market fundamentals. They signalled that pockets of demand in select regions could prompt isolated adjustments but that broad based increases were unlikely while construction activity remained weak. Market participants therefore expected a cautious stance on pricing.

The report highlighted that despite intermittent recovery in shipments during June, the underlying demand trajectory remained muted as monsoon hampered site level activity and logistics. Commercial builders and retail dealers both reported constrained order books and slower payment cycles, which in turn reduced room for margin expansion among manufacturers. Analysts noted that unless government project execution accelerates markedly, demand improvement would be gradual. Price setters were thus likely to focus on protecting market shares rather than pursuing aggressive increases.

Market watchers said the near term outlook would be shaped by monsoon progress and fiscal spending patterns, with any acceleration in public works offering the most tangible support. Traders expected that regional variations would persist and that trade flows between surplus and deficit centres would determine local price movements. The report concluded that stakeholders should prepare for a period of subdued pricing until demand signals strengthen.

Cement Prices Set To Stay Under Pressure In July

Monsoon and weak demand keep prices under strain

A report by Centrum said cement prices are expected to remain largely flat in July as the monsoon and weak demand weigh on the sector. The report said demand during the first quarter of FY27 remained range-bound and below expectations, with dealers across markets pointing to subdued construction activity, labour shortages, elections, heatwaves and slower execution of government projects as key reasons. It noted that some recovery was witnessed in June due to delayed onset of the monsoon and quarter-end volume push.\n\nDealers across most markets do not expect any meaningful price increases in July, the report said, adding that attempts to raise prices in some markets are aimed at defending existing levels rather than achieving significant gains. The sharp correction following the rollback of April hikes has largely played out across most regions, limiting scope for further immediate increases. Seasonal slowdown in construction activity during the monsoon is expected to continue affecting demand and pricing in the coming months.\n\nCentrum indicated that pricing pressure is likely to persist through the second quarter of FY27 as monsoon-related softness continues. Dealers remain cautious about sustainability of any price rise attempts and do not rule out further weakness during the peak monsoon period. The combination of subdued demand and seasonal factors is likely to constrain the industry’s ability to raise prices in the near term. While June saw some improvement in volumes because of delayed rains and quarter-end sales efforts, the broader demand environment remains challenging.\n\nCement companies are therefore expected to focus on maintaining current price levels rather than pursuing aggressive increases as the sector navigates weak demand and seasonal headwinds. The report suggested that unless demand conditions improve significantly, limited scope will exist for meaningful price recovery. Market participants remain watchful for any shifts in execution of infrastructure projects or construction activity that could alter the outlook.
