Waterproofing Membranes

<span style="font-weight: bold;">Purtop is a range of polyurea-based membranes for rapid applications.</span><br /> <br /> The Purtop range is a series of continuous, two component, polyurea-based membranes without solvents, suitable for application on various types of substrate.<br /> <br /> <span style="font-weight: bold;">Technical characteristics</span><br /> They may be used to waterproof both, new and existing structures, and have the following characteristics: Adapt perfectly to any shape of substrate.' Excellent bond to various types of substrate thanks to a complete range of primers for any type of material. <br /> Immediate waterproofing and set to foot traffic. 'Excellent tensile and tear strength. High static and dynamic crack-bridging capacity, including at low temperatures. <br /> Considerable elongation capacity. '&nbsp; Excellent resistance to alkalis, diluted acids and detergents. <br /> No reinforcement required. <br /> Do not generate overloads on load-bearing structures ' Colour of the membranes are unaffected by UV rays ' All PURTOP membranes are marked CE (EN 1504-2). <br /> Purtop 400 M: Waterproofing membrane for large flat roofs and bridge decks.<br /> Purtop 600: Suitable for application on horizontal, sloping and curved surfaces, not subject to traffic, on civil and industrial buildings.<br /> Purtop 1000: Waterproofing membrane to storage tanks, basins and hydraulic structures in general, as well as any structure requiring protection with a high performance membrane.<br /> Purtop HA: Waterproofing membrane for small to medium size terraces and flat roofs, and for repairing surfaces waterproofed with hybrid polyurea or pure polyurea-based membranes.<br /> <br /> <span style="font-weight: bold;">Purtop systems </span><br /> There are three complete systems available with Mapei for three types of waterproofing application:<br /> Purtop System Roof - Spray applied hybrid waterproofing system for non trafficked roofs. It is made of: Purtop 600, Purtop 400M, Primer EP Rustop, Primer M, Quartz 0.25, Triblock P, Primer BI, Primer EP Rustop, Primer M, Quartz 0.5 and Mapefloor Finish 65. It is mainly based on the use of Purtop 600 and Purtop 400 M and, have excellent crack-bridging capacity and resistance to stress of the membranes. This system is extremely versatile and suitable for numerous types of roof. It can be applied on various types of substrate: Concrete, cementitious screeds, terrazzo, porcelain and klinker titles, smooth and stated bitumen membranes resistance to ultra violet rays, aggressive chemicals and wear.<br /> <br /> Purtop System Tank - Spray applied pure polyurea-based waterproofing system for storage tanks, basins and hydraulic structures in general. It is made of: Purtop 1000, Triblock P, Primer EP, Rustop and Primer M. It is mainly based on the use of Purtop 1000.&nbsp; With its capacity to bond to various types of substrate and its rapid application procedure as well as its immediate waterproofing and set-to-foot properties, it is possible to repair the waterproofing capacity of various types of storage tanks and hydraulic structures in general, while the high mechanical strength and dynamic and static crack-bridging capacity of Purtop 1000 make this system suitable for application on any type of substrate.&nbsp; <br /> <br /> Purtop System Deck - Spray-applied hybrid polyurea or pure polyurea-based waterproofing system for trafficked roofs and bridges and viaduct decks. It is made of: Purtop 400M, Purtop 1000, Primer SN, Quartz 0.25, Mapefloor I 914, Triblock P, Primer M, Quartz 0.5, Purtop Primer Black and Quartz 1.2. It is mainly based on the use of Purtop 400 M and Purtop 1000, and is extremely versatile and suitable for numerous types of trafficked roofs as well as trafficked surfaces typically found on many types of infrastructures. This system can be used to repair the waterproofing capacity of various types of existing trafficked roofs and decks. Also, being relatively thin, Purtop membranes&nbsp; do not generate overloads on load-bearing structures, and their resistance to high temperatures means that asphalt can be poured directly on their surface.<br /> <br /> (Communication by the management of the company)<br />
