baka may expert sa waterproofing dito. its basically a concrete roof, and everytime pinagagawa namin eh may tulo pa rin sa loob. i remember nilagyan na sya ng carbon fiber sa ilalim ng palitada hen some waterproofing white paint, tumutulo pa rin. maybe because may crack na sya ngayon dahil gumalaw ang lupa. we also had the outside concrete wall painted with waterproofer, may pumapasok pa rin ng tubig.

right now ang balak ko eh flinkote waterproffing type 3, then patungan ng roofguard. any other suggestion? they said this combo might only last 5 years. which is ok for me since this roof has been a money pit for us.
