Why other products are not totally successful in stopping leakage & seepage problems ?

The intention of publishing this booklet is to educate masses about  these reasons.
To know the actual reasons we have to go back to the origin of cement 
which was invented in the west about 100 yrs.back. When the problems associated with cement started showing up after cement was introduced in the construction industry, remedies were also developed by the same people according to the standards of construction which prevailed there. The products available in the market till date are only a copy of the products developed elsewhere, hence, need not be successful everywhere as the construction standards differ from place to place. In actual practice the quality of sand and cement available in many countries are far inferior to the world’s accepted standards. So, considering all these factors, for a successful waterproofing work, one should use such a product which has been specially developed by a Scientist taking into account such worst possible conditions. Our product BBR Microdite is an offshoot of such an endeavour which can be used with full confidence. As this product has been specially developed to take care of all these conditions, it works well in every part of the world. This gives positive and consistent results.
             If you choose BBR Microdite which is the only product with all the merits mentioned above,  you will be the happiest person as your hard earned money  gets rigthly invested.     

Waterproofing during Rainy Season

Rainy season is certainly an ideal time for carrying out any waterproofing work. This is because the wall and the roofs are practically damp during this season.Because dampness is a pre-requisite for BBR Microdite waterproofing, rain really helps. However, it is not advisable to do the treatment when there is continous rain. The treatment can be done no doubt when rain stops for a few hours. 93 Grade cement is preferable as the setting speed is comparivetly more. But the treated area has to be kept covered with plastic sheets for a few days till drying is complete. The area has to be isolated by making cement stoppers to prevent rain water from entering into the treated area. Injections can also be given using a cement solution containing 2% of Microdite w.r.t. cement. There are two ways of doing this; by injecting into the slab structure or above the slab surface if it is already covered with brick-bat coba, tiles or chips.

Chemistry of Leakage

Leakage is generally caused by factors such as bad quality of sand, its clay and salt content, substandard quality of cement, poor workmanship etc. which lead to the formation of air pockets inside the structure. If the leakage is allowed to continue, the entire structure gets damaged leading to its ultimate collapse. This is because of certain chemical reactions which take place as follows. The steel bars used to reinforce the concrete structures chemically react with water to form iron oxide.The volume of the iron oxide thus formed is greater than the original iron. This results in the iron rods expanding in size and exerting extra pressure on the surrounding concrete mass leading to further cracks and more leakage. Hence, year after year, the leakage goes on increasing until finally the structure is totally damaged. Before Microdite treatment is carried out it is very important that the cause of the problem is identified and diagnosed correctly. If one is sure of the spot from where the water enters the roof, it is sufficient to treat that particular area alone. The area should be separated by making sand stoppers adding little cement. The treatment should be done preferably by pouring excess solution [1:5:7 ] in that particular area. If the entry points cannot be identified correctly it is better to treat the entire area including the parapet walls.

Microdite never fails in its mission. If at all there is any failure, it is only due to the failure of procedure i.e., application of wrong or incomplete procedure due to a lack of understanding of the cause of leakage. The coverage area per Kg.of Micordite given previously is only tentative and it can increase or decrease depending upon the problem.  

The right waterproofing product

1) The right waterproofing compound should have the built-in capacity to neutralize the excess salt and clay if present in the sand used for construction.
2) As cement is basically water-based, the product that is used for waterproofing work should also be cement and water-based.
3) No waxy material which is freely available these days in the market should be used, whether they are coloured or colourless. They form a coating on the surface and cannot last for more than one season. They start cracking up during summer season leading to more leakage during monsoon.
4) It should not be assumed that cracks alone cause leakage and then go look for crack filling products. Water can seep through wall plaster even if there are no cracks. This is because the wall plasters made out of  sub-standard sand & cement virtually behave like blotting papers absorbing water and pushing it right  through the walls. Hence, crack filling alone gives only a partial & temporary relief. 
5) A product that is cement and water-based,withstands weathering, not only fills cracks but also plugs the micro-holes in the cement structure, and also is capable of virtually rejuvenating the defective structure alone should be your right choice.
