However, the snow in November and the intense rains in May and June affected the application of waterproofing products. Groupe Lefebvre, which was the installer, and SOPREMA therefore suggested another technology that was better suited to the site’s weather conditions: ALSAN CIVIL P70 primer and ALSAN CIVIL 773 waterproofing membrane, both PMMA-based products.
“This liquid membrane, manufactured in Québec, can be sprayed even in cold weather, which really improves the speed of execution. In addition to drying very quickly, it can be applied on irregular surfaces, unlike other technologies,” explains Michel Viau, Technical Representative at SOPREMA.
PMMA offers outstanding durability and waterproofing performance. While its cost is higher, it is chosen for its quality and high performance, and because it saves considerable time due to its quick installation. This is a complementary product to SOPREMA’s service offer. It should be noted that SOPREMA PMMA technology has been known worldwide for more than 10 years.
