Decorative Concrete is a very popular option these days and certainly adds value to your home. I am a manufacturer of decorative concrete products and hold half day workshops for DIY people wanting to save money and install it themselves. These products can go over various flooring including tile. Any look from stone to wood to marble can be re created for just over $1 per sq ft. I have just had a front page article done in the Vancouver Sun and would be happy to forward it to anyone interested. If you would like any info on the DIY workshops or on our professional installation service please let me know.
