Concrete / Coba / IPS roofs are highly susceptible to leakages as, over time, they develop pores, capillaries, and micro-cracks. Continuous exposure to sun and rain accelerates deterioration. Temperature-related expansion and contraction, along with structural movements, further widen cracks, allowing water seepage. Without proper waterproofing, these issues lead to dampness, leakage, and long-term structural damage.
