TECHNICAL CHARACTERISTICS

Planiseal 88 is a one-component osmotic mortar, composed of a cement-based compound, selected graded aggregates and special synthetic resins according to a formula developed in the MAPEI Research & Development Laboratories. When mixed with water, Planiseal 88 becomes a fluid mortar that can be applied by trowel, brush or by spray with excellent adhesion to the substrate for complete waterproofing, even in the presence of negative pressure. Planiseal 88 is certified to AS/NZS 4020:2018 for use with potable water. Planiseal 88 corresponds to the principles defined in EN 1504-9 (“Products and systems for the protection and repair of concrete structures: definitions, requirements, quality control and evaluation of conformity. General principles for the use of products and systems”) and the requirements of EN 1504-2 coating (C) according to the MC and IR principles (“Surface protection systems for concrete”).
