The Efficiency of Correctly Specified Duct & Pipe Sealing

The Efficiency of Correctly Specified Duct & Pipe Sealing

In a world of increasing efficiency, even the smallest of items specified incorrectly or not at all can have a catastrophic effect on the Health and Safety, Cost and lifespan of Assets.

What is specification? 
Let's look at what we mean when we talk about a specification; here is an official definition:

"Specification: A detailed description of the dimensions, construction, workmanship, materials etc., of work done or to be done, prepared by an architect, engineer etc."

Specification is the skill of recording specific requirements about work you (or your client) want to be carried out. A construction specification is a well-structured, detailed description of the quality, standards, workmanship, materials, and completion of work to be done which evolves across a project. Specifications are often prepared by architects, engineers, and designers referred to as specifiers and may be published as part of the contractual documentation for contractors to be read in parallel with models and drawings, and as part of the handover information.

So why is it so crucial to use engineered professional sealing systems when Sealing cables & pipes in cable ducts.  

Duct sealing is a critical aspect of maintaining the integrity and safety of cable and pipe installations. Properly sealing these ducts is vital for protecting against various risks, such as liquid ingress, gas leaks, rodent intrusion, and even fire hazards. In this blog, we will delve into five key points that emphasize the importance of specifying the correct duct sealing system.

Regulatory Compliance & Safety:
The specification of a duct sealing system provides clear and unambiguous instructions, ensuring that all aspects of the project align with regulatory and safety requirements. This includes compliance with health and safety regulations such as DSEAR, ATEX, Compex, and other industry standards. By specifying the right system, you eliminate the risk of non-compliance and sharp practices, ultimately creating a safer environment for all stakeholders involved.

Quality & Performance Standards:
A well-crafted specification can define the quality and performance standards expected from the duct sealing system. This includes criteria such as being gas-tight, watertight, age-tested, and easily maintainable. Clearly outlining these requirements ensures that the final installation meets the necessary performance benchmarks, safeguarding against potential failures and hazards.

Clear Definition of Materials & Products:
In the specification, you can clearly define the materials and products that should be used. For example, you can specify a system that includes insert sleeves, for example, a tubular rubber backing system for cable separation and a Grey Fybrid, MEKO free mastic sealant to create a liquid, gas, and flame-retardant seal. Additionally, you can mention preferred manufacturers and suppliers, like AC Cable Solutions Ltd, and design it into drawings using their engineered high-spec’d duct sealing kits for example:

Duct Seal LG – A re-enterable sealing system for cables less than 25mm O/D

DuctSeal LG – A re-enterable sealing system for cables less than 25mm O/D

Duct Seal HG – A re-enterable duct sealing systems for larger, heavier cables

This clarity helps in procuring the right components for the job, reducing the likelihood of subpar alternatives being used.

Cost Efficiency and Asset Lifespan:
A well-constructed specification also supports project costing by considering not only the cost of materials and products but also the long-term benefits. An adequately sealed duct sealing system can save significant amounts of money in the long run. It prevents costly revisits to the site due to failures, protects equipment from deterioration caused by moisture or hazardous material, and extends the lifespan of assets. Moreover, it ensures the safety of individuals working around these assets. Investing in a duct sealing system that meets specifications is an investment in the longevity and safety of the project.

Preventing Substandard Practices:
Perhaps one of the most significant advantages of a detailed specification is its ability to deter substandard practices. Contractors who may not fully understand the project's goals may resort to using low-quality or inappropriate products. A clear specification serves as a reference point, ensuring that all stakeholders are on the same page and adhere to the standards set for the project. It eliminates the room for misinterpretation and enhances the overall quality of the work.

In conclusion, specifying the correct duct sealing system is a fundamental step in ensuring the safety, longevity, and performance of cable and pipe installations. By addressing regulatory compliance, quality standards, materials, cost-efficiency, and prevention of substandard practices, you not only protect your investment but also the well-being of those who rely on the integrity of these systems. Carefully crafting a specification is a small investment that yields significant returns in terms of safety and asset protection.
