Moisture Coming Through New Pavers Over Concrete Pool Patio
Hi.
My first post here and unfortunately its not a good one.
我想如果有人有一些关于发生的事情的信息。
I had a mason recently install Cement pavers over an existing concrete patio around my pool area, some of the area was grass and they laid gravel and sand to level it out so it would be even with the concrete (This area you can see no moisture is seeping through the pavers).
There is a ton of moisture seeping through where the joint sand is and my mason is adamant that the sand was incorrect.I gave him the benefit of the doubt and let him put new polymeric sand in.The moisture is still appearing but now it seems more evident than ever. This is now three weeks into the finished job and it just will not disappear. I have sen someone else posted this topic but wanted to see if anyone could please advise me on the issue.
I am in the east coast Connecticut and the weather the since the job was done has been at an average of mid 50’s.
Please see attachment.
I thank you for your time and any advice would be greatly appreciated.

We need to find out more information here to narrow the causes down.
How old is the concrete the pavers sit on? Water does evaporate from curing concrete over time so we just want to make sure curing concrete is not the source here. I'm guessing it's not that new.
You mentioned polymeric sand was used to lock the pavers. Did the mason spray water over the surface to set the sand? Did he lift any of the pavers to check for moisture under the pavers when he re-did the sand? If he added more sand and again wet locked it there is now more moisture under the pavers. If he used a pressure washer to blow out the initial polymeric sand there is even more moisture under the pavers. Any rain you have had will not help this situation. Since it's only been in the 50's and much colder at night it may take a while to dry.
Was the concrete slab level to begin with? Pitched properly? If not moisture could be pooling underneath the pavers and then wicking up or evaporating through the joints
在混凝土庭院下方有蒸汽屏障吗？
Hi.
感谢你的回复。
The concrete at a rough guess would be maybe 12-15 years old.
在铺设聚合物沙子之前，我认为他们不认为他们在摊铺机上喷洒水，而且没有他们从未抬起任何摊铺机检查水分。梅森确实刮掉了原来的聚合物沙子，我确实看到他们这样做，当它被释放后，他们叶子爆炸。昨天我们有一个轻微的雨雪。
Yes the Concrete slab was pitched correctly as when I was getting estimates for this job I also had a new liner put in the pool and had pool companies inspect the area.
我不认为在露台下有一个蒸气屏障，但我不确定。
Hope these answers help.
附加是混凝土的两个图像，草地区是原始红色摊铺机的原始红色摊铺机被贬低。
感谢您提供更多信息。当使用聚合物砂时喷砂在砂中喷洒水以激活并硬化接头中的砂。我想知道那种水是否已在摊铺机下方迁移。一年中的这一时期将需要更长时间的事情来干涸。你提到梅森说聚合物沙子是“不正确”。他描述了这个问题吗？
Good to hear the concrete is pitched correctly.
Are there screenings under the pavers or do they sit right on the concrete?
你好呀。
I met with the mason yesterday and posed some questions to him.
The pavers he said were laid on top of the concrete and they laid onto the cement ( no screeners as far as what I know).I asked if there should be some sand to absorb the moisture and I don't recall him laying the sand. He did say that due to the cold weather it may take time for the Polymeric sand to harden He is monitoring this issue and I am awaiting his response. I will update with any info I have.
当摊铺机干燥时的典型安装超过了一个.5“到1”的沙子或筛选或筛选在板坯或石头底座上。在低点处，通过硬表面底座钻出排水孔，以便在低点下钻孔，以帮助排水。摊铺机也可以在砂浆上设置，但在商业设施中更常见。
如果水分仍然是一个问题，你可以问承包商为什么他干燥直接在混凝土上铺设摊铺机。
感谢你的回复。I will be sure to ask the mason this.
梅森想要再次测试聚合物沙子。肯定为什么他一直想这样做。我问他是否应该在混凝土板上设定排水孔，他不认为这将纠正这个问题。当它开始热身时，每天早上凌晨10点开始，水分开始播出，并且整天将保持可见。
好的。祝你好运。在摊铺机下方的平板和筛选或沙子中的排水孔都为水分提供了一种方法，以逃避与摊铺机和摊铺机接头的恒定接触。
感谢您的输入。
你们好吗？？？
你会帮我吗？
I have a SIMILAR ISSUE: theres a “V-shaped” Wetness.
在这里，我有3张照片，始终显示冬季摊铺机下的V形湿度，秋季甚至现在，春天2021。
BIGGEST Problem is- my House is barely 8months old.
曲线球是摊铺机远离水/大型池塘的20英尺，导致河流 -
然后到切萨皮克。
Contractor said-
“这是正常的，因为我家的高水位。”
IS THAT TRUE?
Is the wetness under the pavers NORMAL???????
请帮助。
