Leak Detection
Our leak detection service utilises advanced electronic methods to pinpoint water ingress sources in buildings. We specialise in identifying breaches in roof membranes, glazing systems, and structural components. Our non-invasive techniques ensure minimal disruption while providing accurate diagnostics for commercial and residential properties across the UK.
Waterproofing Integrity Testing
This service verifies the effectiveness of waterproofing membranes using electronic leak detection and differential pressure methods. We test newly installed and existing systems to ensure watertight integrity. Our comprehensive reports include marked-up plans and certificates, helping contractors meet quality standards before project handover.
Roof Condition Surveys
Our roof condition surveys assess the integrity of flat and pitched roofs using electronic testing and visual inspections. We identify potential issues like membrane breaches and insulation damage. The service includes maintenance recommendations to extend roof lifespan and prevent water ingress in commercial and large residential buildings.
Building Leak Investigations
Specialist investigations to identify leak sources in complex buildings, including basements, facades, and glazed structures. We employ moisture profiling, ultrasound testing, and borescope inspections. Our detailed reports provide targeted repair solutions for commercial properties and large residential complexes nationwide.
Planned Roof Maintenance
Annual and biannual maintenance programs to ensure roof longevity. Services include electronic leak detection, debris removal, and technical audits. Our proactive approach helps prevent water damage, maintains structural integrity, and ensures safe working environments for contractors on commercial and large residential properties.
