Densyl Sealing Mastic in Riyadh | Sealing Mastic Supplier in Riyadh

For enquiries about Densyl Sealing Mastic in Riyadh, Nassguard supplies Densoseal 16A™ Sealing Mastic for sealing cable ducts, conduits and service-entry sleeves. The compound moulds around cables and pipes to close gaps through which water or gas could enter buildings.

Its ability to adhere to damp surfaces makes it useful for below-ground service entries where achieving completely dry conditions can be difficult. Nassguard supplies sealing materials across Riyadh, Dammam, Jubail, Jeddah and Al Khobar.

What Is Densoseal 16A™ Sealing Mastic?

Densoseal 16A is a firm, fibrous, non-setting sealing compound based on polybutene, fatty acids, mineral fillers, organic fibres and water-displacing materials.

Installers pack it into duct openings and mould it around services to form a continuous seal. Unlike a curing sealant, it remains plastic and self-supporting, allowing it to accommodate substrate movement.

Key Features of Densoseal 16A

The product combines hand-mouldable consistency with properties suited to service-entry sealing.

• Water and gas ingress protection helps seal pathways through ducts and conduits.
• Wet-surface adhesion allows application to suitable damp substrates.
• Non-setting construction retains plasticity rather than curing into a rigid plug.
• Self-supporting consistency helps the compound remain in the packed opening.
• Movement accommodation allows the material to respond to vibration and substrate movement.
• Multiple substrate compatibility includes iron, steel, brass, lead, glazed earthenware, polyethylene and PVC.

Applications of Densoseal Sealing Mastic

Densoseal 16A suits service openings where the installation requires a packed seal against water or gas ingress.

• Cable ducts: Seal around electrical or communications cables entering buildings.
• Service-entry sleeves: Fill suitable spaces between sleeves and service pipes.
• Below-ground conduits: Close openings where underground ducts terminate inside a structure.
• Utility chambers: Seal service penetrations into suitable chambers and manholes.
• Maintenance projects: Reinstate disturbed service-entry seals after cable or pipe alterations.
• Pipe-joint profiling: Shape mechanical joints on pipes before applying a suitable protective tape system.

These applications are relevant to building and utility projects across Riyadh, Dammam, Jubail, Jeddah and Al Khobar, subject to the project’s sealing requirements.

Preparing and Sealing Cable Duct Openings

A successful seal depends on thorough packing around every service, including spaces between adjacent cables.

• Clean the opening: Remove dirt, dust, loose rust, scale, previous sealants and other contamination.
• Check substrate condition: Damp surfaces are acceptable, although drying the substrate improves adhesion.
• Separate the cables: Leave sufficient space around each cable for the compound to surround it.
• Shape the material: Remove the packaging and mould manageable portions to fit the opening.
• Pack from the deepest point: Build the seal outward to a depth equal to the duct’s diameter or width.
• Compact every interface: Press firmly against duct walls and services without leaving gaps.
• Finish flush: Smooth the compound level with the duct end and inspect for voids or fissures.

Inspection, Storage and Maintenance

Inspect the seal after installation and whenever work disturbs the cables, pipes or surrounding opening.

• Check for gaps around each service and along the duct wall.
• Inspect the exposed face for fissures, displacement or physical damage.
• Reinstate disturbed material following cable additions, removal or repositioning.
• Investigate recurring ingress to establish whether the problem involves the seal or another building pathway.
• Store unused blocks correctly in their original packaging, upright and away from direct sunlight.
• Keep installation records showing the location, application date and subsequent repairs.

Frequently Asked Questions

1. What is Densoseal 16A used for?
It seals cable ducts, conduits and service-entry sleeves against water and gas ingress.

2. Is it the same product as Densyl Mastic?
No, Densoseal 16A is a separate sealing compound with its own composition and specifications.

3. Can it be applied to damp surfaces?
Yes, it adheres to suitable damp substrates, although a dry surface improves adhesion.

4. Does Densoseal 16A harden after installation?
No, it remains non-setting and plastic.

5. How deeply should the material be packed?
Pack it to a depth equal to the duct’s diameter or width, working from the deepest point outward.

6. Is it a bitumen or butyl mastic tape?
No, it is a mouldable polybutene-based sealing compound, rather than a tape.

7. How can I order sealing mastic in Riyadh?
