  • Polyurethane Liquid Waterproofing membranes
    The need of waterproofing and protection of constructions for a better future and living conditions has led to new innovations and the use of high state-of-art synthetic polyurethane polymers, the so-called liquid membranes. Polyurethane waterproofing membranes are liquid applied systems that offer decisive advantages particularly where seamless systems are desired; either structurally or aesthetically, and for geometrically complicated connections with ventilation outlets or upturns. These systems cure to yield seamless membranes with long-term flexibility while sealing around even in the most complex protrusions becomes easy. Advantages of Polyurethane liquid waterproofing membranes: · 2 mm coat thickness in 2-3 layers at most. · no significant load increase on lightweight decks and roofs. · UV resistant, no coat protection required. · easy to repair, even locally. · long term maintenance is quick and low cost. Membrane removal will not be necessary, whatever the kind of maintenance. · application on top of existing waterproofing systems is possible. All these benefits make it sound too good to be true but there is a catch: It is critical to success the right choice of material selection from the various alternatives in the market. Therefore, for effective waterproofing, the polyurethane liquid membrane must have the following attributes: · Impermeabillity. Obviously, zero water penetration is required. · Flexibility. They must withstand the normal movements of building structures (e.g. distortion, contortion, earthquake activity etc.). · Durability. They must be able to retain their integrity for long periods of time. · Breathability (sometimes required). Membranes must be able to breathe so that moisture vapours from building interiors and substrates can escape freely. · Humidity barrier (sometimes required). Essential in hot and humid climates. · Resistance. The membrane must withstand environmental and climatic conditions. Not all polyurethane membranes on the market satisfy these criteria! Especially, in the construction industry the importance of applying advanced durable solutions is crucial. At the end, a good polyurethane coating will display the following: · Zero water swelling rate and high retention of tensile strength, hardness and elasticity under prolonged exposure to harsh climatic conditions (UV, wetness, heat, ozone etc.) · Constant adhesion to the substrate when periodically exposed to harsh climatic conditions. · Superior performance in an environment which combines all possible climatic conditions. ALCHIMICA revolutionized the waterproofing technologies globally, being the game changer in global waterproofing technologies. We have shifted the focus worldwide from multi-layer systems, traditionally thought to guarantee water-tightness, to new systems based on advanced technology liquid membranes. We offer a wide range of Polyurethane Liquid Membranes which fulfil the above requirements. The waterproofing products available from ALCHIMICA are tailor made to provide long term protection against all natural elements. From roof waterproofing to below grade walls and foundations to highways and bridges or simple under-tile roof waterproofing of residences, the bottom line is one: ALCHIMICA is the only provider you need!
