potential damp concrete floor - TilersForums.com

[simontr]

Hi

Just about to embark on a new kitchen in my old house. The concrete floor is currently tiled with no obvious signs of damage. I would like to just take the existing tiles up and put new porcelain tiles down but two builders i have had in to quote for other work have expressed concern that their is no damp course so we should also take the concrete floor up

seems a big expense for no massive reason. Is there anything i can do to put on top of the concrete ( a membrane?), or is there a specific cement i should be using to adhese the tiles when you are dealing with an older house

cheers, appreciate any help

Simon

Hello simontr, welcome aboard TF.

Welcome along to Tf. Are there any obvious signs that the floor is damp?

what type of tiles are already on the floor..

 

[simontr]

no, just the walls suffer a little, again no damp course, but no damage of the floor - the concrete is around 6 inches deep

cheers

tiles are ceramic ( i think ) - around an inch think. Actually quite nice but the mrs want them up!

inch thick....sure there not quarry tiles?

You could use a liquid dpm, latex over it then tile...

thats sounds good, I want it to last but digging up the floor etc will probably add on a £1000 so this seems a good solution,

Mapei do a product called Mapelastic, its for waterproofing dams, cellars etc, it's not cheap but works, try their technical department.
