Waterproofing Works at Ndere TALA Resort in Kisoro District (Phase I & II)

TETRABUILD Services Limited was contracted to undertake waterproofing works to two iconic hotel structures having mostly circular and dome shaped walls and roof structures. The structures are constructed from mostly local volcanic stone with minimal structural columns and brick walls.

The hotel structures make up Ndere TALA Resort located in one of the remote villages of Kisoro District close to the Rwanda and DR Congo borders. The resort has a breath taking scenery of Lake Mutanda, Mount Muhavura and the D.R Congo mountain ranges.

The waterproofing works were undertaken using the APP Torch On membrane primed with a bituminous coating. The rising damp issues were treated using a combination of Dryzone cream (chemical DPC), Bituminous damp proofing (Insucoat) and Xypex waterproofing products (Concentrate and Admix).

The stone dome surfaces were treated using Fosroc Nitocote SN522 WB from the exterior while the interior plastered surfaces were treated using Fosroc Nitocote CM210 an elastomeric cementitious waterproofing. The leaking joints between the stones were treated using Thioflex primer tubes. All repair mortars and plastered surfaces were treated with Xypex Admix (Waterproofing chemical) added to mortar.
