vesieristyslevyjä

Vesieristyslevyjä, often translated as waterproofing boards or decoupling membranes, are specialized building materials used to prevent moisture damage in wet areas of a building. These areas include bathrooms, shower enclosures, saunas, and kitchens. The primary function of these boards is to create a waterproof barrier behind tiles or other finishes, protecting the underlying substrate, such as plasterboard or concrete, from water ingress.

These boards are typically made from materials like extruded polystyrene foam or modified bitumen, and they come in various thicknesses and sizes. Their construction often involves a core material that is impermeable to water, sometimes covered with a reinforcing fleece on both sides. This fleece provides a surface that allows for good adhesion of tile adhesives and grouts, ensuring a seamless and durable waterproof layer.

The installation of vesieristyslevyjä is a critical step in creating a long-lasting and water-resistant wet area. They are cut to size and attached to walls and floors using appropriate adhesives and mechanical fixings, depending on the substrate. Joints between boards, as well as internal and external corners, are then sealed with special tapes and waterproofing compounds to ensure complete continuity of the waterproof barrier. The effectiveness of the waterproofing system relies heavily on the correct installation of these boards and associated sealing products. By preventing water from reaching structural elements, vesieristyslevyjä significantly reduce the risk of mold growth, rot, and structural damage.
