Slipform
construction
The formwork rises steadily while concrete is placed, so the shell is cast as one continuous structure.
Overview
Chimneys made
where they stand.
An RCC (reinforced cement concrete) chimney is not delivered from a factory. The reinforcement is fixed and the concrete is placed at the plant, so the chimney is made on site by a construction contractor. That is the work BrajProjects does.
BrajProjects Pvt. Ltd. is based in Ahmedabad, Gujarat and works with factory owners, EPC companies, consultants and boiler manufacturers on new RCC chimneys and on work at existing plants. Our direct project list includes chimneys up to 91 m high in several Indian states.
If you are comparing suppliers who use the words "manufacturer" or "manufacturing contractor", see RCC chimney manufacturer in India for what to ask each one.
Construction methods
Three documented approaches.
Slipform
Climbform
construction
The shell is cast in successive lifts. When a lift has gained strength, the formwork is raised and fixed for the next.
Taper chimney
machinery
Listed in our company profile as a third technique. Ask our team how it applies to your structure.
The method is agreed against your drawings, site and programme. See construction capabilities.

What to send with your enquiry
A short brief is enough to start. The more you can share, the more specific our reply can be.
- Plant name, location and project stage
- Chimney height and internal diameter, if the design is available
- Boiler or process details (capacity, fuel) if the size is still to be decided
- Drawings, lining requirement and any inspection or documentation requirements
- Target programme, site access and who supplies which items
Industries we are asked about include sugar and food, distilleries, chemical, steel, power and cement.
FAQs
Before we discuss your project.
Does BrajProjects manufacture RCC chimneys in a factory?
No. RCC chimneys are constructed on site. BrajProjects is a construction contractor and builds the chimney at your plant using slipform, climbform or taper chimney machinery, as suited to the project.
Do you work across India?
Yes. BrajProjects is based in Ahmedabad and serves industrial chimney projects across India. Share the project location and scope when you enquire.
Can you work on an existing chimney?
BrajProjects offers RCC chimney modification and refurbishment. The proposed work needs to be discussed against the existing structure, available records and site conditions.
Who decides the chimney height and diameter?
The approved project design does. Boiler capacity, fuel, site and pollution-control requirements all feed into it. Our calculator gives a preliminary estimate only.
Do you also build concrete silos?
Yes. BrajProjects also constructs concrete silos for industrial bulk storage. See concrete silo construction.
