I have a drainage issue that I need to deal with: former homeowners installed a paver patio, but failed to give it the proper grade. A portion of it is now pitched toward a wall of the house which it meets. The water thus both runs toward a wall of the house, and pools in areas close to the house. As a result, I am now getting some moisture in my crawl space. The water seems to be coming in from both where the pavers meet the wall (the top of the crawl space wall), and from the bottom of the foundation of the crawl space wall.
I spoke to one landscape contractor (Bravo) about the situation. He felt that, because you cant pull up a portion of the pavers, without disrupting the rest of the patio, it was not worth trying to fix the grade. It would just be too big of a job. Instead, he suggested a drain that would run the length of the wall where the pavers meet the house. I also spoke to a general contractor (Bob Hume), who suggested trying waterproof the area where the pavers meet the house. Both seem like good ideas, however, I'm wondering whether the landscape contractor was correct about the difficulty in trying to regrade a paver patio. I'm also wondering whether I'm still going to have a problem with moisture coming up from the bottom of the crawl space wall. This seems to be happening when the ground beneath the pavers becomes fully saturated, and cannot hold anymore water.
Any ideas or suggestions are appreciated, as are the names of contractors. |

To regrade you have to take up all the pavers, stack them, add stone dust or sand and grade the base, reinstal the pavers and then lock them together with sand. Basically you have to pay for a new patio minus materials but plus the labor to remove the pavers to do the foundation/grade work.
Regrading is the best solution, but you are talking big bucks. |

This is a large area we are talking about, and I just don't want to spend the $ to redo the whole patio. Perhaps we will eventually replace the pavers with blue stone, but I don't want to get into paying for that now. Do the proposed alternative solutions of a drain and waterproofing make sense? Any ideas? |

If you put in a trench drain it will cost $$ if you want it to look nice. Don't bother being pennywise if later you are going to replace pavers with bluestone. Whichever solution you choose....do it correctly and to your highest standards. We always seem to go 7-8 years before the long-planned Phase 2 of any project kicks in. |

A perforated pipe wrapped in landscape fabric and buried in gravel would probably work, however you might have to build a dry well for drainage if the slope away from the house doesn't allow an outlet to the lawn. However, unless you do it yourself, this is going to be pretty expensive because of the labor.

Don't waist your time or money. It has to be redone. When you have the time remove and stack the bricks to the side yourself. Find someone to regrade,compress the ground and lay the brick back down. This is the most cost effective way to go.Only labor involved and should not take more than 1 or 1-1/2 days to complete.You will not be happy with the quick fix. Just my thoughts.... |

The paver patio extends into a paver path that is the entire back side of the house, and runs along the side of the house. This would be a huge job, which I really don't want to have to tackle now. But, this isn't somthing that can really wait beyond the spring/summer, because I don't want to just ignore the moisture I am getting in my crawl space. Why won't the drainage system and waterproofing work? I was planning on tying the drains into leaders that run to the street. |

Uh - how do you plan to install the drainage system without taking up pavers? You may end up with a chain reaction you didn't bargain for.
Because of the pitch issues, waterproofing is probably not a real solution. I have had many landscapers, contractors, etc. look at our yard and the solution is always the same: regrade & drain. I have seen a pattern tho, in that this seems to be something that pro landscapers are better able to fix than contractors. This is not surprising, as yard issues are not necessarily a core competency for contractors. Then again, I wouldn't ask a landscaper to build an addition, so it probably all works out. Either way, it is quite expensive.
Many people, including us, have been there/done that with yard water issues around here. We were lucky in that our worst back-pitch problem was a walkway on the side of the house we never use. We took it up, regraded & planted grass seed.
We still have to deal with the big ticket yard drainage issues. It was in this Spring's game plan, but we're having unexpected internal renovations, so it has to wait.
In the meantime, we will stick with our short-term, very cheap solution: basement Wet-vac. Sears, less than $100. |

Daniel, that is basically what I am talking about.
Here is a link, in a lot of detail, but with some pictures.

You have to pull them all up. No question. |
