               I am from India and the place where I live no one seems to know about crystalline technology. Even my architect has not shown any interest to my approach.  I even tried searching a lot on net but could not find any answer to my problem.
                My question is can I use xypex concentrate to waterproof 10 inch brick wall above the ground from positive side by applying a coat of it over and above the plaster. The brick wall will
      first receive two coats of cement sand plaster (1:5 ratio) mixed with an integral waterproofing compound (other than xypex). The thickness of the first coat and second coat of plaster will be 10mm and 15mm respectively.   
                Will this mehod completely waterproof my walls from lashing rain assuming that the plaster and wall is free from cracks visible to naked eyes?
                Is it advisable to use xypex concentrate directly as an integral waterproofing compound in the plaster mixture along with cement sand and if yes then in what ratio.
               Also, the foundation is made of concrete slab of 9 x 12 inch. I’m sure here I can use xypex concentrate coating to make my foundation waterproof.
                Now I am well aware of the fact that Xypex is basically for concrete structures but the plaster too contains cement which is an integral part of concrete.
               I have also gone through your earlier reply regarding waterproofing of brick walls in basement but my case is a bit different so I am still confused.
                What should I do. Please advice. Thanks.

      We have got a very strong representative in India called at Appar Group.  I would suggest contacting them at 91-120-409-0900.
      It is difficult for me to make specific recommendations for your situation given I do not have a strong understanding of the other construction products in India.  Specifically, I do not know what is commonly used to waterproof the sand cement parge coat that is being installed on the brick.

      If you have trouble getting in touch with Appar please contact me back directly at
