Vertical Compression Seal is a D-type EPDM compression seal designed specifically for vertical movement joints in walls and facades. The solid EPDM rubber profile is compressed into the vertical joint between wall or facade sections and is specified across commercial, institutional and high-rise buildings where vertical joints must be sealed against the weather.
Built for vertical orientation, the D-type profile holds its sealing pressure against gravity and wind load while flexing with thermal and structural movement. Its weather, UV and ozone resistant EPDM compound keeps facade and wall joints watertight and intact through prolonged sun exposure and monsoon-driven rain, protecting the building envelope over the long term.
Key Benefits
- Purpose-made for vertical wall and facade joints, not adapted from a flat seal
- D-type profile holds compression against gravity and wind load
- Keeps vertical joints watertight to protect the building envelope
- Flexes with thermal and structural movement without splitting
- Weather, UV and ozone resistant EPDM endures harsh exposure
- Indian-made by Dhawan Associates to ISO-certified quality standards
Applications
- Vertical expansion joints in external building facades
- High-rise and tower vertical wall joints
- Commercial and office building facade joints
- Institutional building exterior wall joints
- Precast and cladding panel vertical joints
- Vertical joints between adjoining structures or wings
Features & Construction
- D-type solid EPDM rubber profile for vertical joints
- Compression fit that maintains sealing pressure on vertical faces
- Vertical wall and facade orientation
- Weather, UV and ozone resistant elastomeric compound
- Accommodates thermal and structural movement in the joint
- Continuous lengths for an unbroken vertical seal line

| Material | EPDM rubber |
| Application | Vertical wall / facade joints |
Installation Guide
- Clean the vertical joint and remove dust, laitance and loose material
- Confirm the joint width and select the correct D-type profile size
- Prepare and prime the joint arrises for the wall or facade substrate
- Apply adhesive lubricant to the seal and joint contact faces
- Compress the D-type EPDM profile and insert it into the vertical joint
- Work along the joint keeping compression even from bottom to top
- Remove surplus adhesive and inspect the vertical seal for continuity
Maintenance & Care
Vertical Compression Seal needs little maintenance once installed. Periodically inspect facade and wall joints from access points, looking along the vertical line for dirt build-up, and rinse exposed elevations during routine facade cleaning to keep the seal face clear.
Check that the D-type profile remains firmly compressed in the joint, has not slipped or sagged, and that the sealing face is uncracked along its length. The EPDM resists weather without any coating; should a section be damaged it can be cut out and re-fitted to restore the watertight line. Dhawan Associates supplies matching D-type profiles.
FAQs
Vertical Compression Seal — Frequently Asked Questions
What is the Vertical Compression Seal?
It is a Dseal D-type EPDM compression seal made specifically for vertical movement joints in walls and facades. The rubber profile is compressed into the vertical joint to seal it against weather while allowing movement.
What does D-type mean for this seal?
D-type refers to the profile shape of this Dseal vertical seal, designed so it holds compression and sealing pressure on vertical joint faces rather than horizontal ones.
What material is the Vertical Compression Seal made from?
It is made from solid EPDM rubber, which resists weather, UV, ozone and water and stays flexible. Dseal manufactures it in India under the Dhawan Associates name.
Which joint type does it suit?
It is built for vertical movement joints in walls and facades, sealing the gap between vertical wall, panel or facade sections.
Why use a dedicated vertical seal?
Vertical joints must hold the seal against gravity and wind load, so the D-type profile is shaped to keep compression on vertical faces rather than relying on a flat horizontal fit.
Is the Vertical Compression Seal weatherproof?
Yes. Its EPDM compound is weather, UV and ozone resistant, keeping facade and wall joints watertight through strong sun and heavy monsoon rain.
How much movement does it accommodate?
As a compression seal it flexes as the vertical joint opens and closes with thermal and structural movement. The range depends on the D-type profile size selected for the gap.
Can it be used on high-rise facades?
Yes. It is specified for high-rise and tower vertical wall joints, precast and cladding panel joints, and general facade expansion joints.
How is the Vertical Compression Seal installed?
The vertical joint is cleaned and prepared, lubricant adhesive is applied, and the D-type EPDM profile is compressed and inserted along the joint, keeping compression even from bottom to top.
Does it need maintenance?
Very little. Inspect the joint periodically and rinse exposed elevations during facade cleaning. The EPDM needs no coating, and damaged sections can be cut out and replaced.
What standards back the Vertical Compression Seal?
It is made by Dhawan Associates, certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 covering quality, environmental and occupational safety management.
How is it different from SealMaster-HV?
This is a dedicated D-type vertical seal, whereas SealMaster-HV is a dual horizontal-and-vertical seal rated to 120 mm gaps with added oil and chemical resistance for industrial joints.
Are custom sizes available?
Yes. Dseal makes D-type profiles to suit different vertical joint widths. Contact Dhawan Associates with your joint dimensions for the right size.
Is the seal suitable for cladding panel joints?
Yes. Vertical joints between precast or cladding panels are a core application, where the D-type seal keeps the joint watertight while accommodating movement.
Who manufactures the Vertical Compression Seal?
It is manufactured in India by Dhawan Associates under the Dseal brand, a leading manufacturer of expansion joint systems and covers.
Where can I buy the Vertical Compression Seal in India?
