Nuraseal Aotea

Nuraseal is a flexible, self-adhesive waterproofing 1.5mm thick membrane constructed from an oriented cross
laminated high density polyethylene sheeting and a bitumen-polymer adhesive compound. Totally impervious, flexible, self-adhesive waterproofing sheet membrane suitable for low hydrostatic below ground areas where buildings require damp proofing.
Manufactured by Premier Coatings UK and imported into New Zealand by Nuralite NZ Ltd.
Nuraseal was previously known in NZ as Premseal 100.
On this project the polystyrene protection was fitted by the Builder.
