Accuracy and precision in leak detection is crucial to ensure the structure below and any interior mechanical installations are secure from water infiltration and potential damage. Over the years, various integrity tests have been developed, each with specific advantages and limitations of use. Flood testing to establish the integrity of the waterproofing can be more cost-effective and preferable in some situations where Electronic Leak Detection (ELD) is not possible at the outset. For example, when the existing system doesn’t support ELD testing, such as structures with conductive membranes or where roof finishes are not easily removed, green roofs for example.
Thornton Consulting are specialists in the location and appraisal of water infiltration present on roofs and other structures with waterproofing systems, regardless of the ingress point of the leak in the building. This may initially have become visually evident with mould or damp patches appearing on the interior walls and ceilings and can result in serious structural damage over time if left unattended.
Flood testing carried out by skilled technicians with the application of florescent dyes enable the water pathways to be traced and is suitable for virtually all waterproofing membranes. This method of leak detection is pertinent for any size of building structures, including residential, commercial and industrial premises. Flood testing can also be extremely beneficial for main contractors and roofers of new constructions, to ensure the membrane is completely sealed without defects and there are no potential areas for water penetration, before the work is signed-off. This is often combined with electronic leak detection so that any breaches can be accurately located.
The flood testing is generally carried out over a period of up to 48 hours, depending on the size and roof stability of the structure. Essential pre-testing assessments are made by Thornton Consulting’s technicians to confirm the weight-bearing properties for the estimated volume of water, availability of internal water ingress monitoring during the test period and whether the existing drainage system will withstand the pressure of water release.
Early assessment and any necessary intervention detected during the flood testing avoids the consequences of greater expense and disruption to rectify water damage to property and content in the future.
