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
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
Are these cracks on the inside or outside, or both?
If they are in the plaster, fine Polyfilla would do, and I reckon that
exterior Polyfilla coloured to match the brickwork would do the outside. I
suspect the problem will not go away and you'll have to keep re-doing this
because the two parts of the house are bound to move independently,
slightly. I wouldn't worry about it unless the cracks get very big or are
bigger at the top than the bottom, signifying that the extension is settling
and leaning away from the main house.
