In the world of construction, waterproofing can be one of the most critical aspects of a construction job. Waterproofing is especially important when laying commercial-grade tiling for pedestrian walkways or driveways for vehicles. A flooring underlayment serves as a barrier between a concrete foundation and a tile application placed on top. If water penetrates the surface and reaches the concrete substrate underneath, it can cause significant damage resulting in expensive and time-consuming repairs. Since moisture is the biggest issue when laying a high traffic tile floor, an equally durable underlayment is required. In Mexico, several major infrastructure projects needed a commercial-grade, watertight, and cost-effective underlayment solution. A polyurea underlayment is one of the most reliable options available.  LINE-X Polyurea Underlayment LINE-X Polyurea Underlayment LINE-X Polyurea
