Shuttering in Civil Construction: Essential Guide for Food Factory Projects
Introduction to Shuttering in Food Industry Construction
Shuttering, also known as formwork, is a temporary mold used in concrete construction to hold freshly poured concrete until it hardens and gains strength. In the food factory design and construction sector, proper shuttering ensures hygiene-compliant, robust, and long-lasting structures—critical for food safety and compliance with industry regulations.
This article is tailored for food processing consultants, food manufacturing consultants, and engineering consulting services involved in food industry construction projects.
What is Shuttering in Concrete Construction?
In food-grade facilities and other industrial buildings, shuttering is used to support slabs, beams, columns, and shell structures during construction. It is vital for shaping structural components and ensuring durability and alignment.
Well-designed formwork contributes to:
- Faster project completion
- Higher concrete quality
- Safety and structural precision
Types of Formwork (Shuttering) Used in Food Factory Design
1. Timber Formwork
Commonly used in small to medium-sized projects:
- Lightweight and easy to work with
- Cost-effective for short-term use
- Needs treatment to prevent warping, shrinking, and swelling
- Best for customized layouts in food processing plant design
2. Plywood Formwork
Ideal for smooth concrete finishes in hygienic environments:
- Reusable up to 20–25 times
- Fast assembly and dismantling
- Suitable for food-grade concrete surfaces
3. Steel Formwork
Best suited for large-scale food factory projects and repeated use:
- High strength and durability
- Non-porous, does not absorb concrete moisture
- Ideal for curved surfaces like silos or tanks
- Produces smooth finishes, reducing the need for plastering
Key Requirements of High-Quality Shuttering
To meet food industry construction standards, shuttering must:
- Withstand dead and live loads
- Maintain shape with proper propping and bracing
- Be tightly jointed to prevent cement grout leakage
- Be easily removable without damaging the concrete
- Use reusable, eco-friendly materials
- Offer a smooth finish for cleanroom applications
- Resist distortion from moisture or weather exposure
Shoring in Industrial Construction
Shoring is used to provide temporary support to trenches, structures, or vessels under renovation or at risk of collapse. Commonly made from timber or metal, shores are crucial for safety in food processing plant expansions or retrofitting projects.

Construction Process of Concrete Formwork
Key stages in shuttering for food factory construction include:
- Propping and centering
- Shuttering installation
- Camber provision
- Surface treatment and cleaning
- Formwork removal in sequence
Removal Guidelines:
- Vertical formwork (walls, columns) – remove first
- Slab soffit – next
- Beam soffit – last, once concrete gains strength
Applications in Food Industry Construction Projects
Formwork plays a key role in:
- Dairy processing plant construction
- Snack food factory development
- Cold storage unit fabrication
- Food-grade warehouse construction
- Silos and storage tank foundation pouring
