Uni Mortar 1-Z is also suitable for use on its own as a waterproofing layer. Vandex Uni Mortar 1-Z is a surface applied, waterproof cementitious mortar for reprofiling concrete and masonry which does not rely on crystal growth to achieve its waterproofing. As a result, Uni Mortar 1-Z can be used on most masonry surfaces, including sandstone, provided that the surfaces are adequately prepared. Vandex Uni Mortar 1-Z has been formulated using sulphate resisting cement making it ideal for application in sewerage environments. It can be applied to either the pressure or non-pressure faces of the concrete or masonry. Vandex Uni Mortar 1-Z is ideal for reprofiling the inside walls of sewerage processing tanks where acid attack has caused some loss of the original concrete. Other applications include; swimming pools, water storage tanks, and any masonry surface requiring the reprofiling of surfaces with depths in the range of 6 -12 mm, prior to the application of Vandex BB75-Z. Advantages „ Highly abrasion resistant „ Applied to either the pressure or non-pressure face of concrete „ Approved for potable water contact „ Based on sulphate resisting cement making it suitable for use in sewerage processing tanks „ Works on masonry, brick, stone and concrete blocks where crystal growth treatments are not effective „ Non-toxic „ Suitable for permanent sunlight exposure after curing „ Tested to withstand a water head of 70 metres when applied at a thickness of 10 mm „ Colour compatible with the host concrete „ Can be applied to damp concrete Description Vandex Uni Mortar 1-Z is a ready-mixed, cementitious, surface applied, waterproofing and repair mortar consisting of grey sulphate resistant cement, graded quartz sands and inorganic additives. Vandex Uni Mortar 1-Z is waterproof and has been tested to a pressure of 7.0 bar (70m water head) when applied at a thickness of 10 mm. The initial and final bonding capability of Uni Mortar 1-Z is excellent, making it suitable for application to both vertical and horizontal surfaces. It is durable, resistant to frost and heat after setting and remains permeable to water vapour. Test Reports and Approvals Australian Standard AS/NZS 4020:1999 • Potable water compatibility Official Materials Testing Institute Clausthal- Zellerfeld • Mechanical properties • Bend - tensile strength / compressive strength / adhesion / modulus of elasticity LMP Baustoffprufinstitut, Beinwll am Bee • Resistance against sewage • Shrinkage and swelling behaviour / bend tensile and compressive strength / structural composition Design Criteria In most waterproofing and repair applications, Vandex Uni Mortar 1-Z is applied in 1 application by trowel or spray at a layer thickness of 6 - 12 mm. Maintenance No special requirements, any damage identified during normal inspections should be water blasted clean, repaired and recoated as appropriate. Chemical Resistance Vandex Uni Mortar 1-Z protects concrete against sewerage water, sea water, aggressive ground water and a range of chemical solutions. November 2012
