SWELLTITE ® Waterproofing compound of natural sodium bentonite and butyl fully adhered to a High Density polyethylene (HDPE) geomembrane SWELLTITE is a highly effective waterproofing compound made of bentonite fully adhered to a High Density Polyethylene (HDPE) sheet. This composition combines the active waterproofing benefits of bentonite with the strength and puncture resistance of a thick geomembrane. SWELLTITE is a true breakthrough in membrane waterproofing technology. Unlike other membrane systems that require near-perfect installation, SWELLTITE's active bentonite compound can expand and seal installation imperfections or small membrane perforations. SWELLTITE is manufactured to a controlled 2.3mm thickness ensuring uniform application of material to the designer, contractor and owner. This composite consists of a 0.3mm high-density polyethylene geomembrane and a 2mm bentonite composite.with a transparent disposable paper attached. SWELLTITE contains virtually zero VOCs (Volatile Organic Compounds), and can be installed in almost any weather condition on uncured concrete. SWELLTITE works by forming a monolithic membrane when hydrated with water. When wet, bentonite can expand up to 15 times its dry volume. When confined under pressure, expansion is controlled to form a dense, impenetrable waterproofing membrane. The expanding action of the bentonite compound can seal small cracks in concrete caused by settlement, shrinkage or seismic actions, problems over which there is normally no control. SWELLTITE está diseñada para las superficies horizontales y verticales de las estructuras enterradas así como para las cubiertas. Las típicas aplicaciones subterráneas incluyen muros encofrados a una cara, muros de sótano de bloques de hormigón, cubiertas enterradas y túneles. Las típicas aplicaciones por encima del nivel del suelo incluyen las cubiertas de los aparcamientos subterráneos y las terrazas. Adicionalmente SWELLTITE se puede utilizar en interiores, en soleras de salas de máquinas, cocinas y laboratorios. La utilización puede incluir estructuras con presión hidrostática continua o intermitente. Sobre cubiertas, la membrana SWELLTITE requiere de 75mm mín. de recubrimiento de hormigón o tierras compactadas al 85% del Próctor Modificado. Aplicaciones Underground, vertical and horizontal structures including concrete retaining walls, buried roofs, and open or excavated tunnels. Car park covers, terraces, etc. Applications in structures with continuous or intermittent water table.
