Weather Conditions — A Hidden Threat to Waterproofing Performance

Weather conditions play a significant role in the long‑term performance of waterproofing systems. Elements such as heavy rain, high humidity, strong sunlight and temperature fluctuations can gradually weaken even quality waterproofing materials. Heavy rainfall can drive water into tiny cracks and crevices, encouraging leakage and degrading protective layers. High humidity — common in tropical climates like Malaysia — forces waterproofing systems to battle constant moisture, which can affect adhesion, curing and long‑term effectiveness. UV exposure and heat can cause coatings and membranes to dry, crack or lose flexibility over time, while fluctuating temperatures can stress materials through expansion and contraction. Together, these environmental factors pose a continuous threat to the durability of waterproofing performance.

Weather conditions post threat to waterproofing performance

For the third time in the week, heavy downpour came absurdly in the middle of the hot days. The sudden and drastic change in temperature and moisture content pose great challenge to the durability and performance of the waterproofing system.

Buildings (and also waterproofing membrane) expand and contract significantly under the sudden weather change. As a result, rigid and less-flexible waterproofing membrane tends to break and lead to water-leakage. This problem prevails particularly at balcony area, even worse for roof-less, extended and cantilever balconies.

Yet, flexible waterproofing membrane is not 100% foul-proof. Bonding and adhesive strength of membrane is often sacrificed in the pursuit of higher elasticity. Result is~ exposed-waterproofing-membrane (on the roof surface without screeding protection) tends to blister/ bubble up when the heat forces the vapour in the concrete out.

It is never simple and straight forward in getting the right and suitable waterproofing material for different situations. Consult a professional and responsible waterproofing company.

Improve Waterproofing by Understanding Weather Impact

To ensure lasting waterproofing performance, it’s crucial to consider weather impacts during product selection and application. Choosing materials formulated for your local climate — especially in areas with heavy rain and high humidity — and implementing proper surface prep, regular maintenance, and timely repairs can help mitigate the effects of weather‑related stress. By treating weather conditions as a key factor in your waterproofing strategy, you protect your structures more effectively and extend the lifespan of your waterproof systems.
