Smoke bombs :

A versatile tracing tool in the construction industry

In the world of pipe maintenance, smoke bombs have become an essential tool. Whether it's for mapping stormwater and wastewater networks or locating the source of bad odors, these devices offer an effective, fast, and cost-efficient solution.

What is a smoke bomb ?

A smoke bomb is a device that produces smoke. It is generally used to detect leaks in pipes and other confined spaces. There are different types of smoke bombs on the market, each with its own features and advantages.

Combustion smoke bombs

A combustion smoke bomb works by burning a specific material. This material, often a special chemical composition, is designed to produce a large amount of dense, visible smoke when ignited. This smoke can be used for various applications, such as leak detection, emergency situations, or special effects in film and theater. Combustion smoke bombs are generally safe to use, with non-toxic smoke that dissipates quickly. A major advantage is that they are available in several colors, allowing for multi-tracing with no risk of confusion.

Smoke generators

A smoke generator is a device designed to produce a large amount of smoke. It works by heating a special liquid (commonly called "smoke fluid") until it vaporizes, creating dense, visible smoke. There are various types of smoke generators: some are designed for specific applications such as leak detection in ventilation or plumbing systems, while others are used for special effects in film, theater, or fire safety training exercises. They are typically safe to use, with non-toxic smoke that dissipates quickly.

Applications of smoke bombs in construction

Smoke bombs are particularly useful in pipeline maintenance. They help detect even the smallest leaks quickly and efficiently. But their use goes beyond that. They are also used for pipe mapping and connection checks, odor control, building airtightness testing, and more. Additionally, smoke bombs are used to test the airtightness of a building's envelope, whether new or old. They can also be used to test smoke exhaust systems and the effectiveness of extractor hoods.

Connection checks using smoke bombs

For new works acceptance or diagnostics of private and public sewer networks, existing connections can be checked by injecting smoke into the wastewater or stormwater systems in order to :

Odor detection with smoke bombs

Smoke tests are frequently used to detect faults in wastewater connection systems. This technique is particularly effective when odor issues cannot be located by other methods or when testing networks hidden behind casings. Smoke is injected into the pipes using a smoke generator.

The smoke escapes through all possible openings and gaps, highlighting all critical points and damaged areas. This allows for :
• Detection of connection errors
• Localization of air leaks, and therefore potential odor sources. The smoke used is safe for health and has a characteristic smell that quickly dissipates.
