If your house is under construction, a very valuable tip for saving costs.   Interlocking tiles are better than Eurocon/Ultra kind of concrete designer tiles for the following reasons,
1. Interlocking tiles can be laid on bare earth (no need for preparation using PCC foundation or masonry, which are required for concrete designer tiles)
2. Interlocking tiles can be relaid
If your house is just finished, and not your pathways, you can occupy the house the very next day using interlocking tiles.  Later on when the fresh ground settles, you may notice some interlocking tiles caving-in.  You can remove the individual tile and lay sand underneath or fill sand across the pathway and relay the interlocking tiles.   Also if you want water to drain off the interlocking tiles, you can simply fill some cement plaster at the joints.  Of course I have used both for my home, as Concrete designer tiles has a great aesthetics, especially near the entrance.  Â
Cost of Economics:
Interlocking tiles:
Tile: Rs.15 - Rs.25 /sq foot
Ground preparation: Sand at Rs.30 cu/feet, approx. Rs.5-10/sq foot of tile.
Labor: < Rs.3 / sq foot
Concrete tiles:
Tile: Rs.35 - Rs.45 /sq foot
Ground preparation: Sand Rs 5-1o /sq foot, PCC Rs.25-30/sq foot, Plaster Rs15-20/ sq foot
Labor: Rs.12/sq foot
So we are looking at 3-4x savings using interlocking tiles, which have the added convenience that it can be relaid.
