Water Ingress

Identifying and resolving water ingress through accurate diagnosis, compliant detailing, and targeted remedial works.

Water ingress occurs when moisture penetrates the building envelope and travels internally through masonry, cavities, or junctions. It is often misdiagnosed as a surface issue, leading to temporary fixes that fail to address the true entry point. TrayTek specialises in tracing how water is entering the structure and implementing solutions that manage and redirect moisture correctly.

Common Causes of Water Ingress

Water ingress is typically the result of failures in external detailing or moisture control systems.

  • Failed or incorrectly installed cavity trays
  • Defective leadwork at abutments, parapets, or roof junctions
  • Bridged cavities allowing moisture transfer
  • Poor detailing around windows, doors, and penetrations
  • Inadequate water discharge from cavity systems
  • Deteriorated or saturated masonry
Correctly identifying the cause is critical to preventing recurring ingress and internal damage.

How Water Ingress Is Addressed

Effective water ingress remediation focuses on intercepting moisture at the point of entry and restoring correct drainage paths.

TrayTek achieves this by identifying failed junctions, reinstating compliant cavity tray systems, correcting leadwork and roof detailing, and ensuring water is safely discharged externally. Our solutions are designed to stop water tracking within the structure rather than relying on sealants or internal treatments.

This approach provides a durable outcome and reduces the risk of repeat issues.
