OT: lack of drains in the patio and house walls

[briansd1]

[quote=ucodegen]The patio concrete is supposed to meet the house below the weep screed and below the level of the foundation that the outer wall of the house is built on. If it isn’t, water will be driven into the wall of the house and most likely will create dry rot. This weep screed is usually below the foundation sill. The purpose is to shed water outwards if any manages to get in.

Good point ucodegen. I’ve seen houses with planter areas where the dirt gets to the weep screed level.

Moisture around the house is something to watch for.

Happens more than than many people think. I have seen several places where a concrete patio is put in that is higher, and covers up the weep screed. What the people who do this don’t realize, is that there will be a small crack between the patio and house at that location due to thermal expansion and contraction. Water will get in and be able to work its way into the wall of the house.

Yep.. black mold anyone??

[quote=AK]Weep screeds weren’t required back in the ’60s. Back then, the hope was that building paper would keep the framing dry and moisture would evaporate due to the natural permeability of the stucco. It’s possible that’s enough for a dry area like S.D., even in an abnormally wet winter like this one.[/quote]
True, provided that the stucco ends above the ground level. Otherwise capillary action will pull any moisture up the any small crack between the stucco and foundation. That said, I grew up in a house that was pre 1960, in California, that did have weep screeds.

I was going to say “no big deal” until you said there was moisture showing on the wall itself.

Clairmont houses were built w/o a stucco screed and it seems the general plan was to let the water run up against the house before continuing out to the street. All of our concrete was sloped to the house util we had it redone.

If the outside concrete is below the stemwall, then it isn’t as bad, but it is still a problem. If you have too much moisture in contact w/ concrete, the concrete will eventually start to deteriorate. You will see the concrete turn to white powder and start falling apart.

We didn’t have the stucco scraped to install a screed, but we did slope the concrete away from the house and that works well. The eves/gutters and the slope keep water away from the house enough that we don’t have moisture in the stucco.

However, we still have some issues where there is no concrete – i.e. where dirt butts up against the stucco with no screed we still have some issues w/ the stucco turning to powder.

To summarize – If you only have concrete sidewalks in contact w/ the house, I’d slope the concrete and get gutters. If there is dirt up against the house, then you should probably do all three: slope the concrete, put in gutters, and scrape the lower stucco layers and have a screed put in. Of course, matching stucco colors is not fun and you may end up puting a color layer on the whole house.
