Vandex Cemelast is a flexible cementitious membrane and does not rely on crystal growth to achieve its waterproofing. As a result, Cemelast can be used on most masonry surfaces, including sandstone, provided that the surfaces are adequately prepared. Vandex Cemelast has been formulated using sulphate resisting cement making it ideal for application in pH aggressive water. It can be applied to either the pressure or non-pressure faces of the concrete or masonry. Vandex Cemelast is excellent for solving the problem of water seepage through concrete and masonry where live cracks are present in both new and old structures. Vandex Cemelast is ideal for application in potable water structures. It can also be used in applications where live crack movement up to 0.3 mm exists. Advantages „ Permanently flexible and accommodates dynamic crack movement up to 0.3 mm „ Applied to either the pressure or non pressure face of concrete „ Based on sulphate resisting cement making it suitable for use in tanks containing pH aggressive water „ 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 15 metres „ Colour compatible with the host concrete „ Can be applied to damp concrete „ Suitable for use in potable water Description Vandex Cemelast is a ready-mixed, two component, polymer modified, cementitious, waterproofing membrane which is made by mixing Vandex BB75-Z with Vandex Cemelast liquid. The BB75-Z powder component consists of grey sulphate resistant cement, graded quartz sands and inorganic additives. The Cemelast liquid is the polymer component. Vandex Cemelast is waterproof and has been tested to a pressure of 1.5 bar (15m water head). The initial and final bonding capability of Cemelast 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.
