Grout for floor tiles

[waterbabe]

Does anyone have the answer to my grouting problem it is for the tiles on the bathroom floor I have grouted it twice now and after a short time it starts to break away.
Is there a flexible grout I can buy that will stay put I need it to be white in colour

It's been my experience that chipping and breaking tile grout is the surest indicator that the subfloor wasn't properly prepared. It was probably laid directly on the wooden subfloor rather than a cement board like Hardibacker (here in the U.S.).

Having said that, there are several brands of flexible grout such as Uni-Bond available. I'm sure if that brand isn't available in the U.K. another will be. Just ask your favorite DIY store for examples. You're likely to have problems with it from time to time but the overall results will be better than what you have now...

Best of luck!

What Clanad said but the norm this side of the pond is to cover the floor in 6mm ply and screw every 6 inches. Then to use a flexi adhesive and grout.

Thanks very much for your answers I shall purchase the grout that has been suggested and hopefully it will last a bit longer
