Scope

1. Sika BlackSeal Elastic - a water-based bitumen emulsion modified with acrylic latex polymer damp-proof membrane material. Sika BlackSeal Elastic is for use as a damp-proof membrane behind walls of in-situ, precast concrete or concrete masonry to prevent water vapour penetrating to the interior. Sika BlackSeal Elastic is covered by BRANZ Appraisal No. 770.

2. SikaProof® A + 12 - a flexible polyolefin (FPO) sheet waterproofing membrane. SikaProof® A + 12 Waterproofing Membrane is for use as a pre-applied membrane for waterproofing and tanking structural concrete floors and walls to buildings subject to specific design with in-situ structural concrete floors and walls complying with NZS 3101. It is suitable subjected to hydrostatic pressure not exceeding the equivalent of a 15 m [1.5 bar) head of water. SikaProof® A + 12 is covered by BRANZ Appraisal No. 852.

3. SikaProof® Bentonite - natural sodium bentonite contained within a geosynthetic fabric together with other accessory products completing an underground waterproofing system. The system is used as a waterproofing or damp-proofing membrane below ground to protect basements and other underground structures against water penetration and/or water vapour transmission from the ground. The buildings must be subject to specific design. The waterproofing membrane is external to in-situ concrete, precast concrete and concrete masonry basement constructions. It is suitable subjected to hydrostatic pressure not exceeding the equivalent of a 20 m (2 bar) head of
water. SikaProof® Bentonite is covered by BRANZ Appraisal No. 612.

4. Sika Watertight Concrete (Sika WT-200P) - is a permeability-reducing admixture used to assist with the waterproofing of concrete for structures of importance level 1-5 as defined by AS/NZS 1170. Buildings containing Sika Watertight Concrete (Sika WT-200P) must be subject to specific design. Sika Watertight Concrete (Sika WT 200P) must be supplied by a ready-mixed concrete supplier that is certified to the requirements of NZS 3104. Sika Watertight Concrete (Sika WT-200P) is covered by BRANZ Appraisal No. 1150.
