Interesting article. However, I suspect that you could pave the floors with asphalt or seal them with oil and have the same results for the particular health problem the concrete floors are intended to solve. Following the links from the article to the report cited - which is in
Spanish of course - and translating it, there is nothing about the
floors that were covered over other than referring to them as dirt. </font>What would be interesting is to know more about whether those dirt floors that were covered over with cement were sealed with anything, and if so, what. A follow-up research project that would be worthwhile but probably hard to convince authorities to do would be looking into how various alternatives to concrete floors, like well-compacted earthen floors sealed with, for example, multiple coats of linseed oil would perform in solving this problem. <br>
