Istanbul mega-project needs waterproofing to keep the ocean at bay

Vadistanbul is Turkey's largest industrial and urban transformation project. When completed, it will have a shopping mall with hundreds of stores, street shops, office space and a five-star hotel.

The site is located close to the Black Sea, the Sea of Marmara and the Bosphorus. That means a high water table that can be found at a depth of only three meters. That’s why it is essential to completely and reliably waterproof the 22-meter-deep basements.

For the Vadistanbul Boulevard part of the project, the contractor used PREPRUFE® waterproofing solutions. The project required 90,000 m² of the waterproofing membrane to provide superb protection to all built elements, including 3,000 foundation piles, up to levels above the water table.

Project Profile

Keeping water out of a concert hall's basement

Sonoma State University faced several challenges for waterproofing its new concert call. The Green Music Center sits at ground level, but the hall slopes downward, below grade, toward the stage. In addition, several feet of space needed for the building's air supply extended the depth even farther.

There was also a high water table just a few feet below the surface. The Green Music Center designers chose PREPRUFE® waterproofing membrane to protect the structure and BITUTHENE® waterproofing on the exterior basement walls. As a result, everything stays dry. That’s music to our ears!

Former BBC headquarters become a spectacular new development

Television Centre was the headquarters of BBC Television until 2013. The site under went redevelopment to include apartments, offices, restaurants and retail buildings.

Since there was a varying water table, the project called for specific requirements to prevent water migration. The site also contains a complex maze of inverted bends and horizontal paths. Access comes in from a mix of residential, commercial and retail buildings. That required a complete matrix of fabricated movement joints.

The contractors chose PREPRUFE® and ADPRUFE® waterproofing solutions as well as SERVISEAL® waterstop to protect the expansion joints in the concrete. In total, approximately 19,000 m² of PREPRUFE® and 6,000 m³ of watertight concrete enhanced with ADPRUFE® were used on the site.
