My daughter and I are planning to put a patio and short wall at her home. I have read and read and have several questions regarding putting in a paver patio. Everything says it needs to be dry weather, but what if it isn't? Must one have dry weather? I know some say they "tarp" the area and wait, but what if you removed the sod and worked the ground and it began to pour? As it did with us. It seemed like okay weather, but it turned bad. Then the next two days it rained and rained. We did put a tarp over most of it, but it was a mess. Can we compact when damp? I thought that it would really make the soil like concrete to compact it while overly damp. It is not in the right grade yet too. So I wanted to work the soil some more to get it to the right grade. Then we want to bring in crushed rock (0-3/4") and dress out the area and compact it to the grade. I have read several places on recommendation for the crushed rock: they vary from 1" to 2". I'm not sure of the reason for the differences. Can anyone tell me why there are differences in the recommended thickness of the crushed rock? I know after we get that to grade we will do the course sand and only do what we can lay in pavers for that day. I am in a quandary to understand the method of the pipes as it may apply to our project. You see my daughter wants her patio to have concentric rings. It is our plan to radiate from a rounded porch; first one row of harvest and then the reddish pavers; then two rows of the background color and then the accent red; then three and one of the reddish again; four rows, etc. until we reach the boundary. We have a plan for two other ripples coming from other center points. Then intersecting the main one. Okay, I know it is complex, but it is what it is and we are going to do it. The question is when leveling for curves how does one keep it in sections if the work is curved? Or perhaps what I really need to ask is: should we begin in the middle and work out on the sides so that we are able to work only the sand that we can lay that day? Are there any tricks to the curving design of the pavers as we are going to lay them? I have a thick black rubber hose that is about an inch thick. I was thinking that this hose may be a good way to level for the curve. Would that be a good way? The next questions: regard the low Celtik wall. The east side of her home is narrow and has a three foot bank from the neighbor's yard, about four feet across and then her foundation. We are grading at the rate of 1/4" :1.5' from the rear yard to the front. Since there is a wall on the east and a foundation on the west should we put perforated pipe under the walkway to deal with excessive water? We don't want to create water where there has not been water (at her foundation). And we read that the wall (which will have perforated pipe behind it) should not have any drainage directed towards it. So IF we can get it dead flat between the wall and the house and slope it to the front the water will end up in the front. What should we do to minimize this water's affect on the walkway at the front? (It will also be pavers.) I thought with perforated pipe behind the wall that we might be okay with another pipe in front of it and running toward the front the same as the paver walkway. I thought the last place to direct the water would be toward the house. I would think ideally that a small 'u' shaped channel at the foot of the wall sloping to the front might really help, as we could pitch it ever so slightly toward the wall and this channel, but I'm not sure. Woops! I thought I was done until I remembered that I might as well ask anyone who may answer the following as well: She wants gas put in later. I'd like her to lay conduit or something(?) for later access under her patio. If this is done, how is it done? There is no money now for paying to have the pipe put in and inspected, so we want to make it so we don't have to tear up the patio. Or perhaps because it is pavers, we shouldn't worry about it and just lift up the ones we need to when the time comes? I know for those of you who make your living doing this that what she'd pay for is your experience, but she has so little money that it is all she can do to buy all the supplies, which are considerable. So any help that can be given will be gratefully appreciated. And fear not. We are not doing this again. It is a one time venture which we will succeed at, it will just be a question of how easily we'll succeed.http://www.lawnsite.com/images/smilies/hi.gif We hope you can "make our day".
