    Frequently Asked Questions

    What is the difference between waterproof and uncoupling membranes?
    Waterproof membranes block moisture from reaching the substrate, preventing water damage in wet areas like showers. Uncoupling membranes reduce the risk of tile cracks by absorbing stress from substrate movement. Many products combine both benefits for added protection.
    Can these membranes be used with radiant heating systems?
    Yes, many uncoupling membranes—such as those from Nuheat and SunTouch—are compatible with electric floor heating systems. Be sure to select a membrane that’s designed for use with heat cables or mats.
    Do I need both a waterproofing and uncoupling membrane?
    It depends on your project. For showers and wet areas, waterproofing is essential. For floor installations over concrete or wood, an uncoupling membrane helps prevent cracks. Some products, like those from wedi, offer both in one solution.
    Are these membranes suitable for commercial applications?
    Absolutely. Products from brands like USG and HYDRO-BLOK are widely used in commercial construction due to their durability and ease of installation.
    Which membrane is best for shower wall installations?
    For shower walls, use lightweight waterproofing boards or roll-on membranes. Consider options from GoBoard or GURU USA for fast installs and long-term reliability.
