Waterproofing is a crucial process in construction that ensures structures are protected from water intrusion, preserving their durability and longevity. Whether applied in basements, foundations, or roofing, waterproofing prevents water damage, mold growth, and structural deterioration. Various waterproofing materials, particularly waterproofing sheets, play a significant role in creating an impermeable barrier against moisture.
Common Types of Waterproofing Sheets:
1. EPDM (Ethylene Propylene Diene Monomer) Sheets – Highly durable and resistant to UV radiation and temperature extremes, ideal for roofing and foundation applications.
2. PVC (Polyvinyl Chloride) Membranes – Flexible and lightweight, often used in commercial roofing and underground structures.
3. TPO (Thermoplastic Polyolefin) Sheets – Eco-friendly and heat-reflective, widely used in roofing due to their energy-efficient properties.
4. Bituminous Membranes – Typically used for waterproofing basements and retaining walls, offering excellent water resistance and flexibility.
5. HDPE (High-Density Polyethylene) Sheets – Strong and chemically resistant, used in applications like foundation waterproofing and landfills.
6. Bentonite Waterproofing Sheets – Composed of natural clay, these sheets expand when in contact with water, providing a self-sealing, protective layer, ideal for below-grade waterproofing.
