Case study

World One – the tallest residential tower in the world. Located on a large 17 acres site in Upper Worli, Mumbai

PROJECT DESCRIPTION

World One – the tallest residential tower in the world. Located on a large 17 acres site in Upper Worli, Mumbai, this masterpiece will stand close to half a kilometre tall. At over 450 meters when ready, it will comfortably dwarf Q1 in Gold coast, which at 323 meters, is currently the world's tallest residential tower.

CHALLENGES

The ground is made up of different types of solid materials of various origin and empty spaces due to which the surface is permeable and leads to accumulating the water above the ground.

Major challenge we faced was to stop the Groundwater from penetrating into the basement. As the location of the project was close to the Arabian sea, hence the Water table was extremely high. Due to this, the surface was damp which led to improper bonding with the concrete surface and membrane.

Another challenge was to make the surface appropriate and fill the patches on the PCC, which was a taking time taking process.

TIKIDAN SOLUTION

As basement depth was more than 25m due to which underground surface was exposed to hydrostatic pressure and does not ensure 100% weathertightness’s, we recommended to use HYDROSTOP 4PY-P & HYDROSTOP PLUS 4PY-P which ensure a quality result and stop water completely.

A safe and reliable waterproofing solution was required to prevent any water ingress through and around the base slab and situated 25 metres below ground level. Complicated detail at the intersection between the cast slab and the sprayed concrete lining, meant that traditional rear-guard water bars were not an option to seal the joint. The new, innovative, fully bonded waterproofing membrane system HYDROSTOP 4PY-P was selected to prevent water ingress through the base slab. It is a completely engineered solution, which produces a mechanical bond with the concrete, and incorporates a unique grid pattern of sealant that prevents any lateral water underflow and migration between the membrane and concrete. HYDROSTOP 4PY-P is easy and simple to install and jointing solutions were installed around the perimeter of the slab to protect against any water ingress at the interception of the slab and the walls.

TIKIDAN, being the waterproofing expert, is able to provide a comprehensive and custom made waterproofing solution.
