The Morocco Mall, The Largest Shopping Centre in North Africa, Uses GCP

The Morocco Mall, the largest shopping centre in North Africa, was built on a formerly undeveloped area on the southern side of Casablanca. The building project was situated less than 20 metres—approximately 66 feet—from the Atlantic Ocean, posing some interesting waterproofing challenges.

Yet the challenge was worth it. The 2M-square-foot, shell-shaped shopping centre provides ample retail and leisure space, including a 400-seat IMAX cinema, 250 restaurants and shops. It also houses an aquatics centre as well as a children’s park, organic garden, ice rink, spa, and an art space dedicated to Moroccan handicrafts.

The Challenge

The project was situated on an extension of the main Casablanca waterfront promenade and prone to the effects of seawater. Therefore, the designer and the owner needed waterproofing products that would protect the massive concrete slab and the foundation walls from water penetration, as well as from the salt and sulphates in the ground environment. These naturally occurring compounds can quickly deteriorate the concrete and shorten the lifespan of the shopping centre structure.

The Solution

The site’s proximity to the water and the harmful salt and sulphate environment made choosing a waterproofing system for the shopping centre's basement areas an important design decision. After review of several waterproofing alternatives, PREPRUFE® 300R and BITUTHENE® 3000 waterproofing membranes were selected over the originally specified system and proved to be the best choice for the project. Test data on PREPRUFE® vs. other products showed that it outperformed the competition, remained watertight, showed no effect from salt and sulphates, was easier and quicker to install and provided a number of value-added benefits.

PREPRUFE​​​​​​​® pre-applied waterproofing system is based on a unique patented technology. Its Advanced Bond Technology™ allows the concrete to fully adhere to the membrane, preventing ingress of water between the membrane and the structure, unlike conventional non-adhesive membranes, which are vulnerable to water penetration. PREPRUFE® is not harmed by wet/dry cycling and there’s no risk of swelling during the construction phase. PREPRUFE® is chemically resistant in all soil and water types and accelerates project completion schedules.

BITUTHENE​​​​​​​® 3000, sheet-applied waterproofing membrane has been the product of choice for substructure walls in projects throughout the world for years. ADCOR® 500S, SERVISEAL​​​​​​​® 195 and BITUTHENE® Liquid Membrane were also included in the final waterproofing specification.

The Morocco Mall, largest in North Africa, is a unique and amazing architecturally designed structure, further enhanced by GCP Applied Technologies' products that help protect it.
