The Corner Joint System is a corner expansion joint profile designed for wall-to-wall corner conditions. It uses a clip-retained cover to bridge the movement gap precisely where two walls meet, producing a clean finish at both inside and outside corners of a building.
The system handles wall movement at the corner while the clip retention holds the cover firmly in place. Engineered specifically for corner geometry, it maintains a continuous, professional line where standard straight covers cannot follow the turn.

Installation Guide
- Confirm the corner type (inside or outside) and joint width
- Clean both wall faces meeting at the corner
- Fix the clip-retaining members to each wall at the corner
- Position the corner profile to follow the wall geometry
- Clip the cover into the profile for secure retention
- Seal the perimeter where the application requires it
- Check the corner for a clean line and secure clip retention
Maintenance & Care
The Corner Joint System requires only routine care. Clean the profile with a soft cloth and mild detergent, clear any debris caught at the corner gap, and confirm the clip retention keeps the cover seated through wall movement.
If a corner cover loosens, re-clip it into the profile and inspect the retaining members for damage. Contact Dseal (Dhawan Associates) for replacement inside or outside corner components matched to your installation.
FAQs
Corner Joint System — Frequently Asked Questions
What is the Corner Joint System?
The Corner Joint System is a Dseal corner expansion joint profile that bridges wall-to-wall movement gaps at building corners using a clip-retained cover.
Does it suit inside and outside corners?
Yes. The Corner Joint System is designed for both inside and outside corner conditions, maintaining a clean line wherever two walls meet.
How is the cover retained?
The cover is held by a clip profile that clips into the retaining members, keeping it securely seated as the corner joint moves.
Where is the Corner Joint System used?
It is used at building corners where wall-to-wall joints change direction, in commercial, institutional, healthcare and public buildings, indoors or outdoors.
What movement does it accommodate?
The Corner Joint System accommodates the expansion and contraction movement of wall joints at the corner while keeping the cover retained.
What material is the Corner Joint System made from?
The system uses durable profile components; Dseal can confirm the specific materials and aluminium grade for your corner specification.
Can it be installed on existing walls?
Yes. The clip-retained corner profile can be fixed to new or existing walls, making it suitable for both new construction and renovation.
How do I maintain the Corner Joint System?
Clean the profile with mild detergent, clear debris from the corner gap, and periodically confirm the clip retention keeps the cover seated.
What standards apply to the Corner Joint System?
Dseal manufactures the Corner Joint System under ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 certified processes, with aluminium to ASTM B221-02 / ASTM 6063 where used.
How is it different from ClampJoint?
The Corner Joint System is a dedicated corner expansion joint profile, while ClampJoint is a wall-to-wall clip system available in straight and corner configurations for continuous runs.
How does it pair with straight wall covers?
The Corner Joint System completes corner conditions where straight wall covers such as AeroGuard or Aerostar cannot follow the turn, giving continuous joint coverage.
Are custom sizes available for the Corner Joint System?
Yes. Dseal supplies the Corner Joint System configured to your corner geometry and joint width; contact Dhawan Associates with your project details.
Does the Corner Joint System provide a fire or acoustic barrier?
It is primarily the corner cover profile; where fire or acoustic separation is needed at the corner joint, Dseal can advise on compatible barrier accessories.
Who manufactures the Corner Joint System?
The Corner Joint System is designed and made in India by Dhawan Associates under the Dseal brand.
Where can I buy the Corner Joint System in India?
It is available directly from Dseal (Dhawan Associates) across India. Call +91 93109 97953 to order or request a quote.
Why use a dedicated corner profile instead of bending a straight cover?
A dedicated corner profile gives a precise, secure fit and a clean line at the corner, which a straight cover cannot achieve reliably around a turn.
