The Penetron system was specified to provide long-term durability and watertight protection for the raft foundation beneath both towers and for the retaining walls. The structural waterproofing strategy for the Retal Rise project included the following:

  • PENETRON ADMIX, a crystalline waterproofing admixture with tracer, was added to the concrete at a dosage rate of 1 percent of cement content and used to treat 8,000 m3 of concrete.

  • PENEBAR SW-45 swellable waterstops were installed at all construction and cold joints, forming an active barrier that expands in the presence of water to prevent leakage through jointed areas.

  • PENETRON, a topical crystalline waterproofing material, was applied to selected retaining-wall surfaces for added protection, providing another line of defense against hydrostatic pressure and aggressive groundwater conditions.

  • PENECRETE MORTAR, a waterproofing mortar, was used to repair small surface cracks, voids and honeycombing in the raft foundation and retaining walls, as well as tie-rod holes and other penetrations.
