The construction of hospitals is one of the more delicate infrastructure developments that a region plans for. With population growth continuing to rise, the ability to not only build more hospitals but also build them with the ability to handle a larger capacity is a must. In Doha, Qatar, project engineers started the challenge of building the Aster Private Hospital to handle the expected volume it would be experiencing. To do so, the engineers needed to increase the footprint of the building, constructing right to the property lines. Adding to the frustrations was the fact it would experience hydrostatic water pressure, like most buildings in Qatar. A proven waterproofing system was needed.
Dimensions Engineering Consulting firm recommended the use of Krystol Internal Membrane (KIM) concrete admixture as the waterproofing solution. As the application of traditional torch-applied bituminous membrane would have been more complicated and consumed a lot of time and labor to install, KIM admixture was the logical choice. 1,700 m3 (60,000 ft3) of KIM treated concrete was used in the raft slab, retaining walls, and all water retaining structures, which saved the project team time and money because it was added to the concrete at the time of batching.
The construction joints were also a risk consideration for the team. This worry was erased with the use of Kryton’s Krystol Waterstop System (KWS), which waterproofed all construction joints and tie holes to ensure a watertight structure for the life of the hospital.
As of writing the Aster Private Hospital is watertight.
Krystol Internal Membrane (KIM) is a hydrophilic crystalline admixture used to create permanently waterproof concrete.
