Admixture in Concrete
Admixture in Concrete
(OP)
At one of our project contractor wants to use 2% Krystol Internal Membrane (KIM)as an admixture for water proofing purposes. The information for product is uploaded. I never came across using this type of product. Is there someone who knows anything about such products and its suitability to use along with other admixtures like Eucon WR, Eucon 37.
Thanks to all

There are various ways to waterproof concrete by densifying (such as the use of silica fume)or using a hydrophobic admixture. If you choose a product testing can be carried out and warranties can be provided (but of course the warranty doesn't cover workmanship issues).

Whether to try to waterproof the concrete or deciding to use a membrane can often come down to cost and the section size. For example a thin wall could be suitable for using a waterproofing admixture, but a thick slab due to the large volume of concrete to be treated may be more suited to a membrane.

When these products originally came on the market, the companies insisted on strict adherence to minimum reinforcement, minimum cement content and maximum w/c ratio, and wet curing...all to be supervised by their own personnel. In other words, they required quality in construction which would largely make their admixture redundant. These specifications appear to have disappeared from the current manufacturers' literature.

I'm not a believer. Good construction technique and jointing is the way to make concrete waterproof.
