- Structural Decay: Water reacts with metal reinforcements, causing them to rust and weaken the entire building.
- Health Hazards: Damp environments encourage mold and mildew, which are linked to respiratory issues like wheezing and asthma.
- Interior Damage: Seepage ruins expensive interior finishes, furniture, and electrical System.
COMMON WATERPROOFING METHODS.
Cementitious Waterproofing: Often used for internal wet areas like bathrooms, this method uses cement-based coatings mixed with additives for flexibility.
Liquid Waterproofing Membrane: A versatile option where a liquid (like polyurethane or acrylic) is applied by brush or roller to form a seamless, rubbery seal. These are highly effective for roofs because they can handle thermal expansion.
Bituminous Coating: A thick, black petroleum-based layer used primarily for foundations and roofs. While durable, it can become brittle with excessive UV exposure.
Bituminous Membrane: Self-adhesive or torch-on sheets that provide a heavy-duty shield for flat roofs and underground structures.
Chemical Injection: A specialized technique where chemicals are injected into wall cracks to block water paths at the molecular level, often used in basements or for repairing existing leaks.
