Cementitious Fireproofing in Saudi Arabia

Reliable Passive Fire Protection for Steel Structures and Industrial Projects

Introduction

Fire safety is a fundamental requirement in modern construction projects across Saudi Arabia. As the Kingdom continues its rapid industrial and infrastructure expansion under Vision 2030, ensuring structural fire resistance has become mandatory for factories, warehouses, commercial buildings, and large-scale developments.

Among the most widely used passive fire protection systems is cementitious fireproofing. This cost-effective and durable solution provides critical fire resistance to steel structures, helping maintain structural integrity during fire exposure. In Saudi Arabia’s industrial sector, cementitious fireproofing is commonly specified to achieve fire ratings ranging from 1 hour to 4 hours, depending on project requirements.

Cementitious fireproofing systems are especially suitable for industrial environments due to their performance, affordability, and ease of application. They play a vital role in protecting steel structures from high temperatures and preventing premature collapse.

What is Cementitious Fireproofing?

Cementitious fireproofing is a spray-applied fire-resistant material composed of cement-based or gypsum-based compounds mixed with lightweight aggregates and fire-retardant additives. It is applied directly to structural steel members such as beams, columns, and decks.

When exposed to fire, the material acts as a thermal barrier, insulating the steel from rapid temperature rise. By slowing heat transfer, cementitious fireproofing maintains the steel’s load-bearing capacity for a specified duration.

This system is classified as a passive fire protection solution, meaning it does not require activation or mechanical operation. It works automatically during fire exposure.

Why Cementitious Fireproofing is Essential in Saudi Arabia

Steel is a preferred construction material due to its strength and flexibility. However, it loses approximately 50% of its strength at around 550°C. In a fire scenario, such temperatures can be reached within minutes.

In Saudi Arabia, industrial facilities often include:

Large open-span steel warehouses
Manufacturing plants
Oil and gas support buildings
Power and utility facilities
Logistics and distribution centers

These facilities require reliable fire protection systems that comply with Saudi Building Code (SBC) and Civil Defense regulations.

Cementitious fireproofing provides:

Structural stability during fire
Life safety protection
Compliance with regulatory standards
Cost-effective fire rating solutions
Long-term durability in industrial environments

Types of Cementitious Fireproofing Materials

Cementitious fireproofing products are generally classified into two main types:

1. Gypsum-Based Fireproofing

Lightweight material
Suitable for interior applications
Economical solution
Common in commercial buildings

2. Portland Cement-Based Fireproofing

Higher durability
Better resistance to moisture and impact
Suitable for industrial environments
Preferred for factories and warehouses in Saudi Arabia

Portland cement-based systems are widely used in the Kingdom due to their ability to withstand harsh climate conditions.

Applications of Cementitious Fireproofing in Saudi Arabia

Cementitious fireproofing is commonly applied in:

Industrial factories
Steel warehouses
Commercial buildings
Shopping malls
Power plants
Oil & gas facilities
Industrial cities projects (MODON developments)
Parking structures

Its versatility makes it suitable for both new construction and retrofit projects.

Fire Ratings and Thickness Requirements

Fire ratings are determined by the required duration of protection:

1-hour fire rating
2-hour fire rating
3-hour fire rating
4-hour fire rating

The thickness of cementitious fireproofing depends on:

Required fire rating
Steel section size
Hp/A ratio (heated perimeter to cross-sectional area)
Approved design specifications

Professional contractors measure dry film thickness using calibrated gauges to ensure compliance.

Installation Process

The correct application of cementitious fireproofing is essential to achieve certified performance.

1. Surface Preparation

Steel must be clean and primed with approved coatings. Any rust, oil, or contamination must be removed to ensure proper adhesion.

2. Mixing

The material is mixed with water using specialized equipment to achieve the required consistency.

3. Spray Application

The material is sprayed onto steel members using high-pressure spray machines. Application may be done in multiple passes to achieve required thickness.

4. Thickness Verification

Wet and dry thickness measurements are conducted to ensure compliance with design requirements.

5. Curing

Proper curing is required to achieve full strength and fire resistance.

Advantages of Cementitious Fireproofing

Cementitious systems offer several advantages:

Cost-effective compared to intumescent coatings
Suitable for large industrial projects
High fire resistance ratings
Easy application
Non-combustible material
Durable under industrial conditions
Minimal maintenance requirements

These benefits make it the preferred solution for warehouses and factories across Saudi Arabia.

Compliance with Saudi Standards

Cementitious fireproofing in Saudi Arabia must comply with:

Saudi Building Code (SBC)
Civil Defense requirements
ASTM fire testing standards
UL or equivalent certifications
Approved project specifications

Proper documentation and inspection reports are required for final approval.

Climate Considerations in Saudi Arabia

Saudi Arabia’s climate presents unique challenges, including:

High temperatures
Dust exposure
Humidity in coastal areas
Large temperature fluctuations

Cement-based fireproofing systems are particularly suitable for these conditions due to their durability and resistance to environmental factors.

Cementitious vs Intumescent Fireproofing

While intumescent coatings provide thin and aesthetic finishes, cementitious fireproofing is generally preferred for industrial projects due to:

Lower cost
Faster application for large areas
Higher impact resistance
Better suitability for concealed steel

The choice depends on project requirements, budget, and aesthetic considerations.

Quality Control and Inspection

Quality assurance is critical for fireproofing works. Contractors implement:

Material approval submittals
Mock-up samples
Thickness testing
Adhesion testing
Inspection documentation

These procedures ensure performance and regulatory compliance.

Cost Factors in Saudi Arabia

The cost of cementitious fireproofing depends on:

Required fire rating
Thickness
Total steel surface area
Accessibility
Project size
Material brand and certification

Generally, cementitious fireproofing is more economical for large industrial projects.

Sustainability and Long-Term Performance

Modern cementitious fireproofing materials are designed for long service life with minimal maintenance. They contribute to:

Enhanced building safety
Reduced risk of catastrophic loss
Compliance with insurance requirements
Long-term asset protection

Future Demand in Saudi Arabia

As Saudi Arabia continues to expand industrial cities, logistics hubs, and mega projects, the demand for certified fireproofing contractors and materials will continue to grow.

Industrial safety standards are becoming stricter, and passive fire protection systems are now considered essential rather than optional.

Cementitious fireproofing remains one of the most reliable and cost-effective passive fire protection systems for steel structures in Saudi Arabia. Its durability, performance, and affordability make it ideal for industrial and commercial projects across the Kingdom.

By providing certified fire ratings, compliance with Saudi regulations, and long-term structural protection, cementitious fireproofing plays a vital role in ensuring safety, sustainability, and operational continuity in modern construction projects.
