Sealants are a building’s first line of defence against water ingress, air leaks, and structural movement damage. Over time, UV exposure, thermal expansion, substrate movement, and improper installation cause sealants to crack, shrink, or detach — compromising both performance and appearance.

Our Joint & Sealant Defect Repairs service provides end-to-end rectification, ensuring joints are fully restored to their designed movement and weatherproofing capability. We apply strict industry standards and product-specific best practices to achieve long-term durability.

1. Inspection & Failure Diagnosis

We conduct a systematic review of all joints and sealant applications, assessing:

• Type and location of joint (control, expansion, perimeter, or penetration).
• Visible defects such as cracking, adhesive failure, or cohesive tearing.
• Evidence of moisture ingress or underlying substrate deterioration.

Where necessary, we carry out moisture testing and substrate condition checks to confirm root causes, ensuring repairs address more than just surface issues.

2. Safe Removal of Defective Sealant

Failed sealant is completely removed, not just patched over. We use:

• Precision cutting tools to avoid damaging surrounding substrates.
• Vacuum and solvent cleaning to ensure surfaces are free of contaminants.

This step is critical — residual debris or old sealant remnants will compromise adhesion of the new product.

3. Substrate Preparation & Priming

Depending on substrate type (concrete, brick, aluminium, glass), we:

• Repair or fill any edge damage to ensure clean, sound joint faces.
• Apply manufacturer-recommended primers to promote maximum adhesion.

4. Installation of New Sealant System

We install high-performance, elastomeric sealants (e.g., polyurethane, hybrid, or silicone) tailored to the building’s joint design, movement range, and exposure conditions. Application includes:

• Backer rod installation to control joint depth and shape factor.
• Smooth, continuous application for a watertight seal.
• Tooling to ensure full contact with joint faces and optimal profile for drainage.

For highly exposed façades, we specify UV-resistant formulations for extended service life.

5. Quality Assurance & Testing

Post-installation, we conduct:

• Adhesion pull tests.
• Visual inspection for continuity and proper profile.
• Water spray testing where required by specification or warranty conditions.

6. Documentation & Maintenance Guidance

We provide:

• Product data sheets and warranties.
• Maintenance intervals and recommended cleaning procedures to maximise lifespan.

Outcome:

Atomic Projects ensures every joint and sealant repair is not just a cosmetic fix, but a fully engineered solution that restores your building’s ability to resist weather, movement, and ageing — safeguarding both its performance and appearance for years to come.
