The Heart of Europe - aka The World - Dubai UAE

-

The Heart of Europe is probably the most iconic project of the 21st century, standing out as one of the most exclusive real estate destinations worldwide, offering investors a rare chance to own luxury villas, hotels, and unique floating homes (https://thoe.com/the-floating-seahorse/) . The Arabian Sea is extremely salty and the Maincon wanted to ensure that the product had good protection against permeability and chloride ingress. Samples of CWS Admix were tested at world renowned Wimpey Laboratories and were proven to offer outstanding water penetration resistance and intense chloride ingress arrest, making it ideal for use in such aggressive environment.

Repairing a heavily cracked concrete slab with CWS100

June 2024 - July 2024

This rooftop was suffering from intense cracking was leaking like a sieve. The Authorized Applicators, treated only a part of the rooftop, so the client would witness the difference between treated and untreated area. A small part of the heavily cracked rooftop was treated with CWS100, after the cold joints around the area were detailed first. During intense rain, the video shows the rooftop from below, where all the cracks in the untreated area are leaking heavily, while the CWS100-treated area is completely dry and the cracks are visibly sealed and completely dry, a live testament to the heavy duty crack sealing performance of CWS100.

32 days ponding test. The longest concrete waterproofing ponding test in history,.

December 2023 - January 2024

The engineering team of Indus Hospital together with the consultants were looking for the best materials for crack sealing, concrete waterproofing and protection of areas of exposed concrete, like rooftops, podiums and ramps, and areas exposed to high abrasion, such as patients’ admission areas, carparks, etc The team asked for a sample application and ponding test to be done, to witness the performance of CWS100. An area of the rooftop about 6-7 square meters was designated for the trial application. After the test area was cleaned, as appears on the attached PDF, asmall “dam” for the ponding purpose was made around the sprayed area and then the test area was flooded with 7 cm of water. The test started on Dec. 13th 2023. and ended on January 15th 2024, 32 days after it had started! The area was inspected and the inspection showed that all the existing cracks had sealed completely, even those who went right through the slab and there were no leaks on the concrete.
