Key Signs of Membrane Degradation

by

Membranes play a crucial role in protecting buildings from water ingress and moisture damage. However, over time, these membranes can experience wear and tear or degradation due to various factors such as UV exposure, extreme temperatures, and physical wear and tear. Understanding the signs of membrane degradation is essential for property owners and facility managers to ensure the long-term effectiveness of their waterproofing systems. Identifying potential issues early can help prevent costly repairs and maintain the integrity of your structure. In this blog, we will explore the common indicators of membrane degradation and the importance of regular inspections to safeguard your investment against water damage.

 

Key Indicators of a failed membrane:

Surface Erosion

Gradual wear of the membrane’s top layer, leading to a rough appearance.
Caused by prolonged UV exposure, weathering, or heavy foot traffic.
Reduces protective capabilities, increasing the risk of water infiltration.

Peeling

Lifting or separation of the membrane from the surface.
Often due to inadequate surface preparation or trapped moisture.
Creates potential entry points for water, jeopardizing waterproofing.

Cracking & Splitting

Fine lines or larger fissures on the membrane surface.
Result of extreme temperature fluctuations or structural movement.
Allows water penetration, leading to leaks and damage.

Uneven Surface

Wavy, bulging, or sagging areas on the membrane.
Caused by moisture accumulation or improper installation.
Can lead to water pooling, heightening the risk of leaks.

Buckling

Raised areas or folds in the membrane.
Caused by thermal expansion or trapped moisture.
Increases stress on the membrane, potentially leading to cracks and water intrusion.

Track Marks

Visible lines or impressions from heavy foot traffic or equipment.
Result from excessive weight or dragging tools across the surface.
May compromise effectiveness.

Punctures

Holes or tears in the membrane.
Caused by sharp objects or heavy impacts.
Compromise waterproofing, increasing the risk of leaks.

Mould & Mildew

Dark spots or patches on the membrane.
Caused by excess moisture and inadequate ventilation.
Can pose health risks and degrade the membrane.

Blistering

Raised bubbles on the membrane surface.
Often results from trapped moisture or air during application.
Weakens the membrane’s integrity and can lead to leaks.

Scratches

Surface abrasions of varying depth on the membrane.
Caused by contact with sharp objects or debris.
Can expose underlying substrate  to moisture, leading to further degradation.

Rust Stains

Discolorations from corrosion of metal components.
Result from moisture exposure to rusting materials or inadequate drainage.

Bandaid Repairs

Temporary fixes covering leaks or damage without addressing the issue.
Arise from reactive maintenance practices.
Can lead to larger, more expensive problems.

Waterproofing is an essential part of maintaining a building’s integrity, but many myths surround its importance and application. Whether you’re a homeowner, builder, or property manager, it’s crucial to understand the facts behind waterproofing to ensure long-term protection. In this blog, we’ll debunk some of the most common waterproofing myths and clarify why proper maintenance and the right materials are key to safeguarding your structure from water damage.

"Waterproofing is Only Needed in Wet or Flood-Prone Areas"...

While waterproofing is essential in flood-prone areas, it’s also crucial in any environment where moisture can cause damage. Water can seep into structures through joints, even in dry climates. Temperature changes, humidity, and even condensation can lead to moisture buildup that damages building materials, causing rust, mould, or deterioration over time.

"Once Waterproofing is Done, It Doesn’t Need Maintenance"...

Waterproofing isn’t a one-time fix. Over time, materials like sealants and membranes degrade due to UV exposure, weathering, or building movement. Regular inspections and maintenance are essential to ensure the waterproofing system remains effective. Without proper upkeep, even a well-installed waterproofing system can fail.

"Waterproofing Will Always Be Expensive"...

While high-quality waterproofing solutions can have an upfront cost, they are an investment in the longevity and integrity of the structure. The cost of repairs resulting from water damage—such as structural repairs, mould remediation, and interior damage—often far exceeds the initial investment in proper waterproofing.

"Waterproofing is Only for New Construction"...

Waterproofing is important in both new and existing buildings. In older structures, joints may have deteriorated, and waterproofing may need to be updated. Even in newly constructed buildings, waterproofing expansion joints is a crucial step to prevent future damage, and it’s essential to maintain it as the building ages.
