Five large money-storing vaults were the focus of this Xypex project. The below grade foundation is subjected to eight meters of head pressure. Because of this situation, two coats of Xypex were applied to the exterior of the vault walls and floor slab. Before the application of the final coat, the cold joints around the base of the slab were routed out and treated with a slurry of Xypex Concentrate, followed by Xypex Patch'n Plug.
Lower Ruvu Water Purification Plant
Dar Es Salaam
Over 50 tons of Xypex crystalline waterproofing were applied to this large purification plant near Dar es Salaam. Areas of application included digester and clarifier tanks, reservoirs, above and below grade concrete walls, and roof decks. In addition, concrete defects such as rock pockets and cracks were repaired with Xypex products.
The new Tanzanian Embassy in Addis Ababa was considered a very high profile project and stringent guidelines were imposed for the specification of all products. Xypex was selected as the preferred waterproofing technology and Xypex Concentrate was applied to the entire basement and balconies.
