Apply a waterproof coating or sealant, repair cracks immediately, and ensure proper drainage to prevent water accumulation against the wall. Water-repellent chemical treatments during construction also help prevent future seepage.

Waterproofing your roof involves applying a protective coating or membrane that prevents water from seeping through. Common methods include liquid waterproofing membranes, bituminous coatings, or polyurethane-based systems. The surface must be cleaned and cracks repaired before the waterproofing material is applied evenly to create a watertight seal.

Water penetrates concrete through capillary pores, hairline cracks, construction joints, and around pipe penetrations.
