Hi kiongozi. Mostly you need to to have this checklist 1 ensure you lay a polythene sheet or dpm before you do steel fixing. 2. During concrete mixing for slab casting ensure you use water proofing admiture and the right of concrete mix not less than M20 3.During concrete pour ensure efficient vibration of concrete using vibrator 4. Ensure the slab floor gradient not less than 3 degree and water drain time not more than 10min after water is poured that a test you do to check on slope of your. . Use floor finish like terrazzo and use a specialist for that Having checked all this you will have. A good leak free flat roof Cheers
