I have 2 hairline cracks on the walls of my house, the house is 16 years old so I suppose some settling is the reason. Whats the best `cure`? some fine filler or gouge out a channel and fill or what?
If anyone wants to comment on this! the main part of the house has a `floating foundation` I think thats what it is called, done by an engineering company at the time of construction. The 2 cracks are where the floating foundation ends (we extended slightly at the time) One where there is a metal beam to extend the kitchen behind the garage and the other in the garage from the window down towards the floor , both parts (i think) outwith the floating foundations. Any cause for concern? the cracks are probably less than a millemetre in width.
thanks
