Rasolastik EVO is designed for waterproofing and protecting concrete and cementitious substrates in both internal and external applications. It is suitable for swimming pools, spas, potable water tanks, reservoirs, canals, basins, concrete pipes, terraces, balconies, podium decks, bathrooms, showers, laundries, and underground external walls. The membrane is compatible with in‑situ concrete, precast concrete panels, cement screeds, cement‑lime mortars, cement plaster, old ceramic finishes, and selected timber substrates.

Rasolastik EVO is approved for use in contact with drinking water and complies with EN 1504‑9 for concrete protection against penetration, humidity control, and increased resistivity. It provides resistance to both positive hydrostatic pressure (up to 5 bar) and negative counterthrust water pressure (up to 2.5 bar).

When applied to a total dry film thickness of 3 mm in two or more coats, Rasolastik EVO meets the requirements of NZBC Clause E2 External Moisture and Clause E3 Internal Moisture as part of a compliant system. It also supports compliance with NZBC Clause B2 Durability and F2 Hazardous Building Materials. Suitable for use in all New Zealand climate zones, including coastal, high‑rainfall, and seismic regions, provided it is tiled over or otherwise protected from long‑term UV exposure.

• Rasolastik EVO must not be applied over bitumen, painted, contaminated, or unstable surfaces unless prepared and primed in accordance with the technical data sheet.
• The membrane is not UV‑resistant and must be fully covered with tile, stone, render, or another protective finish for long‑term exposure.
• Not suitable for substrates with active structural movement, rising damp, or moisture content above manufacturer’s specified limits.
• Areas subject to high negative hydrostatic pressure or active water ingress may require alternative or additional waterproofing measures.
• Application must achieve a total dry film thickness of 3 mm in at least two coats, with a maximum per‑coat thickness of 1–2 mm depending on the application method.
• Only potable water‑approved installations may be used for drinking water containment applications.
• Use is restricted to stable and structurally sound cementitious substrates, old ceramic finishes, or approved timber surfaces.
• Installation must be carried out by trained applicators familiar with liquid‑applied membrane systems in accordance with TANZ Best Practice Guidelines and the IWAM Code of Practice.

Rasolastik EVO is BRANZ Appraised as both an external waterproofing membrane (Appraisal No. 541) for compliance with NZBC Clause E2 External Moisture and an internal waterproofing membrane (Appraisal No. 542) for compliance with NZBC Clause E3 Internal Moisture. The membrane also supports compliance with NZBC Clause B2 Durability, delivering a minimum 15‑year service life in wet area and submerged applications when installed according to the manufacturer’s instructions, and NZBC Clause F2 Hazardous Building Materials, as it is solvent‑free, low VOC, and non‑toxic.

The product meets EN 14891:2012 Class CMO1P performance standards for liquid‑applied waterproof membranes under tile finishes, including crack‑bridging, water impermeability, bond strength, and immersion resistance. It also complies with EN 1504‑9 for concrete protection, including protection against penetration, humidity control, and increased resistivity.

When applied to a total dry film thickness of 3 mm in two or more coats, Rasolastik EVO provides long‑term waterproofing protection for both internal and external applications, including potable water containment, swimming pools, terraces, balconies, podium decks, and underground external walls. It is suitable for use in all New Zealand climate zones, including coastal, high‑rainfall, and seismic regions, provided it is tiled over or otherwise protected from UV exposure.

Rasolastik EVO has been widely used in New Zealand and internationally as a high‑performance waterproofing and concrete protection membrane. In New Zealand, it has been incorporated into both residential and commercial projects requiring council‑approved waterproofing under NZBC Clause E2 External Moisture and E3 Internal Moisture. It is widely specified for external fascades, swimming pools, potable water tanks, balconies, terraces, podium decks, basements, and underground retaining walls.

Internationally, Rasolastik EVO has been proven in European infrastructure projects, including potable water facilities, reservoirs, canals, and public aquatic centres, where compliance with EN 1504‑9 and EN 14891 standards is critical. Its combination of fibre reinforcement, high crack‑bridging capability, and resistance to both positive and negative hydrostatic pressure makes it a trusted choice for challenging wet area and submerged applications.

The membrane’s long‑term performance record and BRANZ Appraisals (No. 541 External, No. 542 Internal) provide assurance for architects, engineers, and waterproofing contractors seeking a durable, compliant, and council‑accepted solution. It continues to be a preferred product for tiled waterproofing systems across all New Zealand climate zones, including coastal and high‑rainfall regions.

Rasolastik EVO is a fibre‑reinforced, single‑component cementitious waterproofing membrane that provides excellent crack‑bridging and flexibility, accommodating substrate movement without compromising waterproof integrity. It achieves a crack‑bridging capability of approximately 0.95 mm at +23 °C without reinforcing mesh and offers resistance to both positive water pressure (up to 5 bar) and negative counterthrust pressure (up to 2.5 bar).

The membrane is certified for use with potable water and meets EN 1504‑9 requirements for concrete protection, including protection against penetration, humidity control, and increased resistivity. It is impermeable to liquid water while remaining vapour‑permeable, allowing the substrate to breathe while preventing water ingress.

Rasolastik EVO is solvent‑free, low VOC, and Eurofins A+ rated for indoor air quality, supporting safe application in enclosed environments such as bathrooms, basements, and water tanks. It contains no Red List materials and meets NZBC Clause F2 Hazardous Building Materials.

When installed to the specified 3 mm total dry film thickness and covered with tile, stone, or render finishes, Rasolastik EVO delivers long‑term durability in submerged, external, and internal wet area applications, meeting TANZ Best Practice Guidelines and IWAM Code of Practice recommendations.
