Hello people,

What can you say about adding waterproof cement (Dr. Fixit - Waterproofing Solutions) to the mixture for German floor?

My raft foundation is 4 planks plus the base making 5

The guy working on the project said there is no way the water will touch the floor because of the good height of the raft/beam

Please could someone tell me if we still need to include Waterproofing Solution in the german floor mixture(granite, sand and cement)?

The building is at Awoyaya ibeju/lekki area

Thanks

Aji
