|  Topic: Roof Concrete Strength
Dear Sir
I have purchased one Individual House around 1000 Square Feet which is already Built before One Month.
Builder has shown Steel Reinforcement Roof Camera Picture which shows Main Rod, Distributor Rod, concealed Beam & Roof Beam is Good at satisfaction Level.
But Builder said that 5" Roof Slap & Roof Beam Concrete strength is around M15 level.
But How Can i Check whether it is M15 level or not.
Suppose If it comes below M15 level, I would Like to add 2" more Concrete Slap at M20 Strength over existing 5" Roof Slap. This method is correct??.
OR How to increase Concrete Slap Strength at alternative ways. Please suggest me.
Kind Regards
Jahankumar

Dear Jahankumar. Hello..! Kindly ask your builder about 1. Spacing and size of reinforcement bars laid as main and distribution steel..the thickness is okay. 2. The span of Beams and its reinforcement.The M15 is used for proportion of concrete it is 1:2:4, where 1part cement,2 part sand, 4 part Aggregate ,which is used for general R.C.C.work.its also okay. No need to put extra weight by increasing thickness....regards | | |

As stated by Sh Navneet Jharia is correct. You should take help of any civil engineer, who can see the slab personally and check it by chiseling and hammering and also see the span of the beam and slab. There is no use to add any extra concrete layer to the old concrete slab it will not add any strength but with extra concrete increase the load on the slab which is unnecessary.
