I see two reasons for the problem in addition to JDR's help.

1) Tha there car is Red.

2) No hole at the base of the wall for it to relieve itself.

Thanks for showing us yer crack though, got anymore dirty pictures

No just Newtons law "For every action there is an equal and opposite reaction" except this time its popping out the side. ;-)
And been a hands on builder for 40 odd years ;-)

Well looks nothing serious to me , just a little settlement cracking , dont worry but take jdr s advice , and park forward more , and you will be fine ..

Wack some polyfilla on it and repaint and you will be fine .

Or even back 2 meters..

forward two meters and it will be at the bottom of the garden after it rolls down the hill, and back two meters it will be in the swimming pool. But at least it will get rid of my cracks.

Should my crack get bigger, I will not hesitate to share it with you all

Aye, were looking forward to it In the meantime slap some white paint on top of it like the last person did

The last person was the builder

I rest me case M'lud

I have named it the Berlin Wall

Why, is the car German

No ..... because if it comes down, whats on the other side will come pouring through onto my side

Russians or water ?
