Ready to use, UV and ponding-water resistant, colored, elastoplastic waterproofing membrane, quick drying at low temperatures

TECHNICAL DATA SHEET CE 14891 Solar reflective KEEP DRY is an innovative, versatile, waterproofing solution derived from the proprietary HPC Technology (High Performance Copolymer). The product is one component, solvent based, ready to use and available in different colors. It provides mechanically resistant waterproofing with outstanding cold flexibility and a high bonding strength to a variety of substrates. Thanks to its state-of-the-art elastoplastic copolymer and its viscosity, KEEP DRY is easily conformable to irregularly shaped substrates. The remarkable crack bridging properties make...

KEEP DRY is CE marked in accordance with European Standard EN 1504-2 “Products and systems for the protection and repair of concrete structures” and complies with the following Principles: “PI” Protection against Ingress -“MC” Moisture Control - “IR” Increasing Resistivity. KEEP DRY also meets European Standard EN 14891 “Liquid applied water impermeable products for use beneath ceramic tiling bonded with adhesives” and is approved for undertile waterproofing of floors and walls both indoors and outdoors. KEEP DRY provides certified protection from carbonation, a major cause of reinforced concrete...

Surface preparation Clean thoroughly and remove dust, loose material or non-adhering particles, grease, oil, formwork release agents and any contaminant that may affect proper adhesion. Substrate must be cured, clean, dry, sound, solid and not exposed to rising damp, negative hydrostatic pressure or evaporative flows. Joints and substrate cracks must be treated appropriately as per industry standards: seal control and isolation joints with ICOJOINT MS silane modified polymer or with the self-adhesive sealing ICOARM BUTYL TAPE. • Concrete: prime with a coat of KEEP DRY diluted with 50% ICODIL...

Once the substrate has been accurately prepared and the primer (if needed) has properly dried, KEEP DRY can be applied as is. For new waterproofing apply two or more coats at an overall rate of not less than 2 kg/m2. If used as anti-carbonation protection of reinforced concrete structures, the minimum coverage is 200 gr/m2. The areas that are potentially subject to extra mechanical strain should be reinforced with ICOARM TNT ROLL 100-gr/m2 non-woven fabric. Ensure that the fleece is saturated in order to minimize the risk of delamination. To waterproof green roofs use the specific KEEP DRY AR...

Cracking inevitably occurs in concrete as a result of its poor tensile strength. Visible damages (macro cracks) and invisible ones (micro cracks) originate from static and dynamic external causes, moisture-related expansion and contraction, creep, shrinkage, settlement and differential thermal expansion. Those are critical factors in building durability. Therefore it becomes crucial to protect cracked surfaces from water ingress. The term indicates the ability of an elastic waterproofing system or membrane to withstand without damage the appearance of cracks in the substrate, thus continuing...

PREVENTING CARBONATION-INDUCED CORROSION OF REINFORCED CONCRETE Carbonation-induced corrosion of reinforced concrete The increasing atmospheric contamination entails a serious risk of reinforced concrete decay, since the presence of polluting substances leads to premature concrete degradation by carbonation. Carbonation is the reaction of the carbon dioxide contained in the atmosphere (CO2) with the calcium hydroxide contained in the cement paste: Ca(OH)2 + CO2 ^ CaCO3 + H2O. Carbonation usually occurs already within the first decade of service life of reinforced concrete structures that have...

HEAT PROTECTION Solar reflective waterproofing What’s a “COOL ROOF”? The term refers to roofs that have the ability to improve energy efficiency by reflecting solar heat, thus minimizing air-conditioning energy consumption and the resulting polluting emissions (CO2, SO2, NOX and heavy metals, among others). Cool roofs increase indoor thermal comfort and help save on energy costs. In fact, a dark, “non-cool” roof entails bigger heat absorption and heat transfer to the premises situated underneath, which result in worse living comfort and high cooling energy costs. Furthermore, the heat buildup...

EXTERNAL FIRE PERFORMANCE OF ROOFS B-Roof rating and solar roofs When it comes to fire safety, roofs and roof terraces are the most vulnerable areas of a building due to both rising flames and the fact that roofing materials may fuel the fire. In addition to internal factors, a fire can also be caused by external factors, such as windblown cinder from neighboring building fires or electrical faults in solar systems and related wiring. The BROOF certification carried out using the test methods (t1), (t2), (t3), (t4), in accordance with EN 13501-5, provides the specific fire performance rating...

Hail is a form of precipitation composed of spherical lumps of ice, known as hailstones, which can damage property, crops, and even cause bodily harm. Hail can cause significant damage to roofs and to the overlying waterproofing systems due to their poor resistance to dynamic puncture. Like most weather events, also hail is measured and categorized. For such purpose the Torro Hailstorm Intensity Scale was developed in 1986 by Jonathan Webb, member of the UK's Tornado and Storm Research Organization (Torro), a research body specializing in severe convective weather. The Torro Scale is a 0-10 scale...
