DG Patio with water issue

We recently installed a decomposed granite patio next to our existing concrete patio. The supply store recommended the impermeable weed block which we used. Then laid 7 yards of dg on top and compacted, no stabilizer used. A few days later we had a few showers and there was no standing water which was good, but every morning since (about 3 days), we see wet granite next to the house and patio which has us very worried. We figured the impermeable weed block was our problem so we drilled holes through the dg and weed block to allow water to drain through. It does not appear to make any difference. We really don't want to pull all of this up and start over, so we are looking for advice on other things to try. We do not have gutters on this side of the house so you can see the water line where that rain came off the house. I know gutters are a good long term solution, but would like to put off that expense for the moment, if possible. Thanks for any ideas.

Over time, the floating fines in your granite should dissipate, so living with it for a while is an option. By "impermeable weedblock," I presume you mean heavy plastic sheeting, yes? A better choice would have been a good grade of filter fabric, which allows water to soak through but prevents weeds from penetrating it. If the "wait-and-see" plan doesn't meet your expectations, another option to consider is installing just enough gutter to cover the length of the decomposed granite, and doing the rest when finances permit.

Thanks for the feedback. We dug up the wet area and removed the weedblock from there (yes, it was the plastic stuff). Then tamped the granite back down so we will see what it does. Mainly we are just worried about retaining that much moisture next to our foundation. Do you think ones the floating fines dissipate we will see the granite drying evenly rather than remaining wet for days next to the house?

In your warm, windy climate, it should dry over time. And much more quickly if you get that run of gutter installed.
