The waterproofing is being taken to the next level, the rainwater pipes are now being installed.
They function to allow the surplus liquid from the dome to pour off and prevent water damage. The building is being protected against water seepage on any level and it will be perfectly sealed against moisture. These pipes will be spread across the dome in many locations for maximum efficiency. The HDPE pipes being used are of the highest quality to ensure that they will last at least 100 years.
