NovaLink is a heavy-duty hinged floor expansion joint cover designed for uneven slabs and retrofit work. A single hinged plate spans the joint and pivots to absorb differential slab levels, while anti-slip serrations keep the walking surface safe under both pedestrian and heavy-duty loads. Vapour-barrier and fire-barrier options are available, and the hinge design makes it well suited to retrofitting existing joints where slab faces are not perfectly aligned.
NovaLink covers standard joint sizes of 25.4-101.6 mm (1 inch to 4 inch) and heavy-duty sizes of 100-170 mm (4 inch to 7 inch), with a load rating up to 2,000 lbs. It is built to ASTM E1399 and is ADA compliant, giving an accessible, code-referenced cover for demanding floors.
Key Benefits
- Single hinged plate accommodates uneven and misaligned slabs
- Carries pedestrian and heavy-duty loads up to 2,000 lbs
- Anti-slip serrations keep the cover plate safe to walk on
- Ideal for retrofit where existing slab faces are not level
- Optional vapour and fire barriers add performance where required
- ASTM E1399 tested and ADA compliant for accessible floors
Applications
- Retrofit projects with uneven or misaligned slabs
- Heavy-duty commercial and industrial floors
- Airports, transit terminals and concourses
- Hospitals and institutional buildings needing ADA compliance
- Warehouses and loading areas with rolling loads
- Wide expansion joints up to 170 mm requiring a robust cover
Features & Construction
- Hinged single-plate design for uneven slab conditions
- Standard joint sizes 25.4-101.6 mm (1 inch to 4 inch)
- Heavy-duty joint sizes 100-170 mm (4 inch to 7 inch)
- Load rating up to 2,000 lbs
- Anti-slip serrations on the cover surface
- Optional vapour-barrier and fire-barrier configurations
Technical Specifications
| Standard joint sizes | 25.4 mm – 101.6 mm (1″ – 4″) |
|---|---|
| Heavy-duty joint sizes | 100 mm – 170 mm (4″ – 7″) |
| Loading | Up to 2,000 lbs |
| Standard | ASTM E1399, ADA compliant |
Installation Guide
- Confirm the joint size falls within the 25.4-170 mm range and select the matching unit
- Clean both slab edges and check the differential levels across the joint
- Position the hinged plate cover centrally over the joint opening
- Mark, drill and set anchors along the fixed side of the plate
- Secure the plate so the hinge can pivot freely with slab movement
- Install the vapour or fire barrier beneath if those options are specified
- Check the cover sits level, the serrations face up and the plate articulates correctly
Maintenance & Care
NovaLink is built for demanding floors and needs only periodic checks: confirm the anchors remain tight, the hinged plate still pivots freely, and the anti-slip serrations are clear of debris. Where vapour or fire barriers are fitted, inspect them when access allows to ensure they remain intact.
Should a plate or fixing be damaged by heavy impact, replace the affected unit rather than attempting a partial repair so the load rating and ADA compliance are preserved. For replacement covers, barrier options or sizing help, contact Dseal (Dhawan Associates) on +91 93109 97953.
FAQs
NovaLink — Frequently Asked Questions
What is NovaLink?
NovaLink is a heavy-duty hinged floor expansion joint cover from Dseal. A single hinged plate spans the joint and pivots to suit uneven slabs while carrying pedestrian and heavy-duty loads.
What makes NovaLink a hinge joint?
Its cover is a single plate connected by a hinge, so it can articulate to absorb differential slab levels rather than relying on a flat, fixed plate.
What joint sizes does NovaLink cover?
Standard sizes span 25.4-101.6 mm (1 inch to 4 inch) and heavy-duty sizes span 100-170 mm (4 inch to 7 inch), covering a wide range of joint widths.
How much load can NovaLink carry?
NovaLink is rated for loads up to 2,000 lbs, supporting both pedestrian traffic and heavy-duty rolling loads.
How much movement does NovaLink handle?
The hinged plate pivots to accommodate slab movement and differential levels across the joint; the usable range depends on the selected joint size.
Is NovaLink suitable for uneven slabs?
Yes. The hinge design is specifically intended for uneven slabs and retrofit situations where the two slab faces are not perfectly aligned.
Does NovaLink offer a vapour or fire barrier?
Yes. Vapour-barrier and fire-barrier options are available beneath the cover where those performance requirements apply.
Is NovaLink ADA compliant?
Yes. NovaLink is ADA compliant and tested to ASTM E1399, giving an accessible, code-referenced cover surface.
How is NovaLink installed?
The hinged plate is positioned over the joint and anchored along its fixed side so the hinge can pivot freely. Barrier options are fitted underneath if specified.
How do I maintain NovaLink?
Periodically check that the anchors are tight, the hinge pivots freely and the anti-slip serrations are clear. Damaged units are replaced to preserve the load rating.
What standards apply to NovaLink?
NovaLink is built to ASTM E1399 and is ADA compliant, and Dseal manufactures under ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 systems.
How is NovaLink different from DriveFlex?
DriveFlex is an aluminium-and-nitrile insert joint for carpark decks over a 50-65 mm gap, whereas NovaLink is a hinged metal plate cover for uneven slabs spanning up to 170 mm at loads to 2,000 lbs.
Does NovaLink have an anti-slip surface?
Yes. The cover plate has anti-slip serrations to keep the walking surface safe across the joint.
Are custom sizes available?
NovaLink already spans 1 inch to 7 inch joints, and Dseal (Dhawan Associates) can advise on the correct unit and any project-specific barrier requirements.
Who manufactures NovaLink?
NovaLink is made in India by Dhawan Associates under the Dseal brand.
