Common Causes of Facade Water Leakage in Buildings

Poor Construction and Workmanship – Improper installation of exterior cladding, joints, or sealants often leads to gaps where water can seep in.

Cracks in Facade Materials – Concrete, plaster, or masonry cracks caused by settling, thermal expansion, or vibrations allow water penetration.

Faulty Sealants and Joints – Aging or incorrectly applied sealants around windows, doors, and panel joints often fail under weather stress.

Inadequate Waterproofing – Lack of proper waterproof membranes or protective coatings makes the facade susceptible to rainwater ingress.

Blocked or Improper Drainage – Clogged gutters, downpipes, or poorly designed drainage systems can cause water accumulation and seepage through the facade.

Design Flaws – Facades without proper overhangs, flashing, or slope design can trap water, increasing leakage risks.

Material Deterioration – Over time, materials like bricks, stones, or panels may degrade, absorbing water and allowing it to penetrate inside.
