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.
