patio

hi I am having an old uvpc conservatory removed soon as its no good. I was thinking of laying slabs on the hardstanding to turn into a nice patio area. as the old hardstanding joins the house wall and door will the slabs be ok if layed right against the house wall and just by door. thanks

Yes. As long as the underlying surface is in decent condition, and as long as you don't lay the slabs above the damp-proof course in the house bricks. Just be sure to lay the slabs so there's a slight fall away from the house, so that rainwater runs off away from the wall.

The answer can be no, or not advisable. A typical detail would be the patio is 150mm below the dpc. If so fine, provided rain is not splashing into doorways. The problem is drainage - rain can run down walls, raindrops cause splashes, and patios have to drain somewhere. Hence it may be better to have a drainage gap, filled with pipe bedding/pea gravel.

This becomes more vital if your walls are soft bricks, or it is a wet location, or if you live in an exposed or frosty location.

thanks unfortunately I have looked at the hardstanding and the gap between it and the door weather board is only 2 cm high so def no room for slabs also as hardstanding goes right up to door and wall wont be able to have drainage. its a shame but will have to get rid of the base and start from scratch
