    So as many of you know, paver Pete recommends installing stairs against a house as a self supporting 'square' for lack of a better word.


    We have always installed a length of SRW along the back of the steps in front of the foundation wall... We have never put a 1.5-2" gap between this 'wall' and the foundation however. The more I think about it I now understand the reasoning for air flow, and moisture... but what I don't ever understand is, what does a stair system look like with a 2" gap between it and the house?? Anytime Pete has mentioned this method, he has never talked about hiding a 2" gap between the stairs and the house, or a picture???? Also if there is a gap at the top landing and the house, do the pavers also leave a 2" gap between the top landing and the house?

    I want to start installing like this, I just dont understand how to make a 2" gap not look like the stairs have separated from the house.

    I have never put any "gap" behind my steps unless there was a bump out cantilever off the house.

    I would assume between overhanging the cap/paver at the top and the flashing/J channel on the siding, you don't see the gap from above. From the side, I have to imagine you'll see it unless you have foundation plantings there.

    Put a layer of this up against the exposed foundation wall, build the steps as you normally would. The last step at the house typically sits up against wood siding or plastic siding, or clay brick. It is this section that you could use Paver Pete's suggestion and put a row of blocks and leave the 2" gap. Then its a matter of glueing down a step cap on top of this block but putting it right up to the wall. The air gap below will keep the siding dry, and any water that gets in there should flow down the wall without any issues of standing water. This is where the platon comes in.
    Another alternate solution would be to use blue skin glued to the foundation wall. We use this on concrete overlays to prevent efflorescense from making its way thru.

    Thanks. Blue skin... Is that a brand name of product or just some type of waterproofing material?

    I just build a box of SRW with 4 sides. No need for the wrap

    Ok, so lets say there are 6 levels of steps and they are 8' wide. Thats about 24 face feet of material, ranging from 10 up to 18 or more per face foot. Thats somewhere in the 3 to 4 hundred dollar range. 24sq.ft of blue skin @ .69 cents is ...you work it out.
