WHY WATERPROOFING MEMBRANE
FAILS ?
INTRODUCTION
Waterproofing
membranes consist of waterproof plastic, rubber, or coated-fabric materials. Waterproofing membrane failures can occur due to a
variety of reasons, and it is important to identify and address these issues
promptly to prevent further damage. Because , weall know that “prevention is
better than cure“.
REASONS FOR THE
FAILURE OF WATERPROOFING MEMBRANE
IMPROPER INSTALLATION
Most common reason for waterproofing membrane failure is improper
installation. This can include incorrect surface preparation and improper
application techniques.
The surface on which the waterproofing membrane is applied must be
clean, dry, and free of any contaminants, such as dirt, dust, oil, or loose
debris. Failing to properly prepare the surface can prevent the membrane from
adhering correctly.
DESIGN FLAWS
Different types of waterproofing membranes are designed for specific applications
and environments. So by using the wrong type of membrane for a particular
situation can lead to premature failure.
Proper overlap and adhesion are crucial for creating a continuous
barrier. If seams are not properly sealed or the membrane does not adhere to
the substrate, water can find its way through.
Some membranes may be too thin for the intended application. In areas
with high water pressure or potential movement, a thicker membrane may be
necessary to provide adequate protection.
STRUCTURE
MOVEMENT
If the underlying structure experiences movement or settlement, it can
put stress on the membrane, causing it to crack or detach.
ENVIRONMENTAL
CONDITIONS
Exposure to certain chemicals or solvents can degrade the waterproofing
membrane over time, causing it to lose its effectiveness.
UV radiation from the sun can degrade certain types of waterproofing
membranes over time. Membranes that are not UV-resistant can deteriorate.
WEATHER
CONDITIONS
In cold climates, freeze-thaw cycles can cause the substrate to expand
and contract, potentially leading to cracks in the membrane.
LACK OF
MAINTENANCE
Regular inspection and maintenance of the waterproofing system are
essential to identify and address any issues before they escalate into more
significant problems.
POOR QUALITY
MATERIALS
Using low-quality or expired waterproofing materials can lead to
premature failure. It is crucial to use high-quality, reputable products.
Settlement, settling, or shifting of the building structure can put
stress on the membrane, leading to cracks or separations.
Accidental punctures or damage during construction or subsequent work
can compromise the integrity of the membrane.
CONCLUSION
To prevent waterproofing
membrane failure, it is crucial to follow manufacturer recommendations for installation,
choose the right type of membrane for the specific application, and conduct
regular inspections and maintenance. Additionally, hiring experienced
professionals for installation is highly recommended to ensure proper
application.
