hüdroisolatsioonimastiks

Hüdroisolatsioonimastiks is a type of waterproofing material used to prevent water ingress in construction. It is typically a viscous, semi-liquid substance applied in a continuous layer to surfaces such as foundations, roofs, balconies, and wet rooms. The primary function of hüdroisolatsioonimastiks is to create a seamless, impermeable barrier that protects the underlying structure from moisture damage, which can lead to deterioration, mold growth, and reduced structural integrity.

This material is usually based on bitumen, polymers, or cement, often with mineral fillers and additives to enhance its performance. Bitumen-based mastics are common for roofing and foundation applications due to their excellent water resistance and flexibility. Polymer-modified mastics offer improved elasticity, UV resistance, and adhesion, making them suitable for exposed surfaces like balconies and terraces. Cementitious mastics are often used in bathrooms and other wet areas where they can be integrated with the surrounding concrete or plaster.

Application methods vary depending on the product, but typically involve spreading the mastic with a trowel, roller, or spray gun. It is crucial to ensure a uniform thickness and complete coverage, paying special attention to joints, corners, and penetrations to avoid weak spots. Depending on the specific type and manufacturer's instructions, hüdroisolatsioonimastiks may require a primer for optimal adhesion and can be reinforced with fibreglass mesh for added strength and crack bridging capabilities. Curing times can range from a few hours to several days, after which the mastics form a durable, waterproof membrane.
