Bitumen Sealing Strips in Saudi | Bitumen Sealing Strips in Riyadh

Nassguard supplies Bitumen Sealing Strips in Saudi for sealing vertical joints in road construction and maintenance. Self-Adhesive Densoband™ provides a flexible barrier between asphalt and adjoining asphalt, concrete or road castings, helping prevent water from entering the joint.

Its preformed strip format gives contractors a consistent sealing material for installation alongside hot-laid asphalt. Nassguard supplies requirements across Riyadh, Dammam, Jubail, Jeddah and Al Khobar.

What Are Self-Adhesive Densoband™ Bitumen Sealing Strips?

Self-Adhesive Densoband is a bitumen-based joint tape co-extruded with an adhesive film containing polymer-modified bitumen. It comes in rolls with disposable interleaving and adheres to a prepared vertical joint face.

The strip forms a flexible, watertight seal that accommodates slight movement from traffic loads and temperature changes. Sealing the joint helps reduce water entry and subsequent deterioration around the pavement connection.

Typical uses include asphalt-to-asphalt, asphalt-to-concrete and asphalt-to-steel joints. A compatible primer remains optional where site conditions or project specifications require it.

Key Features of Densoband Bitumen Sealing Strips

Densoband combines a preformed profile with self-adhesion for straightforward joint preparation.

• Self-adhesive backing holds the strip against the prepared joint face.
• Flexible sealing accommodates slight cyclic and thermal movement.
• Water-exclusion properties help protect the pavement joint.
• Consistent strip dimensions support uniform placement.
• Optional primer allows adaptation to specified site requirements.
• Manual or machine application suits different project scales.
• Resistance to acids, alkalis and salts supports road-joint exposure.

Applications of Bitumen Sealing Strips

Densoband joint sealing strips suit vertical interfaces that will receive adjoining hot asphalt.

• Asphalt construction joints: Seals connections between adjoining asphalt sections.
• Asphalt-to-concrete joints: Protects interfaces beside concrete structures.
• Road castings: Seals asphalt connections around suitable metal fittings.
• Pavement reinstatement: Supports joint sealing during road repairs.
• Base and wearing courses: Provides a flexible seal across prepared joint faces.
• Airport and tramway works: Serves suitable specified asphalt-joint applications.

For projects in Riyadh, Jeddah, Dammam, Jubail and Al Khobar, choose the strip according to the joint geometry and paving method. Bridge and other movement-joint applications require confirmation against the actual movement demand.

Joint Preparation and Densoband Installation

Clean, dry joint faces and correct positioning are essential to a continuous seal.

• Prepare an even vertical face, preferably by sawing.
• Remove dust, debris, loose rust and oil before placement.
• Use compatible primer only where required, allowing it to dry.
• Cut the strip and remove its interleaving.
• Press the adhesive side firmly onto the joint face.
• For asphalt-concrete renovation, leave a 5 mm upstand above the existing surface.
• For specified new construction, position the strip level with the surface to be laid.
• Butt-joint right-angle corners and compact the joint edges during paving.

Use this product with hot-laid asphalt. Cold adhesion describes how the strip attaches to the joint face, not suitability for every cold-patching method.

Test Standards and Performance

• EN 1427: Ring-and-ball testing gives a softening point of at least 120°C.
• EN 13880-3: The referenced recovery test gives 25% at 25°C.
• EN 13880-13: Adhesion and extensibility testing at −10°C gives 0.40 MPa, with no loss of adhesive strength.

Inspection, Maintenance and Storage

Check the joint during installation and include it in subsequent pavement inspections.

• Confirm continuous contact before laying adjoining asphalt.
• Inspect corners and strip connections for gaps.
• Check the finished joint after compaction.
• Investigate recurring cracks, settlement or poor drainage.
• Repair damaged pavement promptly rather than relying on the seal to bridge structural defects.
• Keep rolls packaged and protected from contamination.
• Record strip size and installation location for maintenance tracking.

Frequently Asked Questions

1. What are Self-Adhesive Densoband strips used for?
They seal suitable vertical asphalt joints against water infiltration.

2. Can Densoband seal asphalt-to-concrete joints?
Yes, asphalt-to-concrete sealing is a principal application.

3. Is primer compulsory?
No, primer is optional where the project or site conditions require it.

4. Does the adhesive side need flame heating?
No, the strip attaches through its cold-adhesive face.

5. Can it be used with cold patch asphalt?
The installation requirement specifies hot-laid asphalt, so cold-patch use needs separate confirmation.

6. What roll sizes are available?
Standard options are 8 × 45 mm in 12 m rolls and 15 × 45 mm in 6.5 m rolls.

7. How much should I order?
Calculate the total joint length, select the required strip size and allow for cuts, corners and installation waste.

Conclusion

Self-Adhesive Densoband Bitumen Sealing Strips in Saudi provide a practical way to protect asphalt joints against water entry while accommodating slight movement. The preformed profile supports consistent placement across construction and maintenance work.

Correct sizing, dry preparation and proper compaction determine the quality of the finished joint. Contact Nassguard with your requirements for supply across Riyadh, Dammam, Jubail, Jeddah and Al Khobar.
