Private Boutique Hotel
One of Ethiopia’s new hotels, this privately-owned Boutique Hotel has a footprint area of 500 m2, an underground level, and ten above grade floors. The hotel began construction in January 2015; however, it was initially being built without sufficient technical supervisionof the concrete placement causing concrete defects such as honeycombs in numerous locations. These defects, especially in the basement and on slabs, resulted in extensive water leakage.
To mitigate these issues, 2,200 kg of Xypex Concentrate, 1,700 kg of Xypex Modified, and 2,500 kg of Xypex Patch’n Plug were used. These products were applied to various concrete structures of the hotel, and, followingextensive concrete repair works, all structures were completely rendered waterproof by the end of construction. The Xypex product applications were undertaken over a three-year period, in tandem with the “Master Schedule” of the overall project, and were completed in January 2018.
The basement walls and floors, the roof, terraces, elevator pits, and concrete gutters were all waterproofed with a two-coat system ofXypex Concentrate followed by Xypex Modified. Xypex Patch’n Plug was used for concrete repair work in previously built structures and effectively sealed cracks to stop leaking within seconds.
Xypex’s unique crystalline technology works by filling the capillaries present in concrete with a non-soluble crystalline structure. This integral structure fills capillary tracks rendering the concrete waterproof. In the case of the Boutique Hotel, all structures have now been waterproofed and protected resulting in no further leakage.
