Waterproofing failures are not always caused by product quality. In many cases, problems result from poor surface preparation, incorrect overlaps or incomplete detailing. Membrane installation therefore requires as much attention as product selection.
Dusty, dirty or uneven surfaces can prevent proper installation, while sharp projections can damage the membrane.
Joints between membrane rolls are critical. Insufficient overlaps or poorly welded seams may allow water to travel beneath the waterproofing layer.
Internal and external corners require careful treatment to maintain system continuity.
Drains and service penetrations are sensitive areas that must be properly integrated with the membrane system.
Even correctly installed membranes can be punctured or torn during later construction activities, particularly during backfilling.
Foundations, terraces, roofs and infrastructure works can require different membrane characteristics.
For contractors, waterproofing failures can lead to repair costs, warranty claims, complaints and reputational damage. Reliable products from manufacturers such as İzopak should therefore be combined with experienced installation teams.
Long-lasting waterproofing depends on correct products, proper substrate preparation, sound welding and careful detailing.
