My parents live in an old traditional Kerala house. the floors haven't been altered in the last thirty years or so- it has just had coats of red oxide.
It rains a lot in the area, and the water table is generally high. The floor has been showing wet patches these past couple of rainy seasons.
What flooring option can deal with this? How much work would this involve? (Ie is it just laying tiles or some porous flooring, or would it involve other measures too?)
