Waterproofing Works at Ndere Resort in Bulenga; Biira

TETRABUILD Services Limited was contracted to undertake waterproofing works to this project. The structure was constructed from mostly local volcanic stone with minimal structural columns and brick walls.

The structure makes up Ndere Resort of Biira; Bulenga in Kampala along Fort Portal – Kasese road. The resort is part of a vast landscape belonging to the Ndere Cultural Group with a beautiful view of Kampala and the Fort Portal Highway.

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 on one of the domes were plastered and later protected with APP Waterproofing Membrane. 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 the mortar.
