不是那么干凝灰岩n dri
The concrete sub sprayed my poured basement wall a week ago, slapped on tremco warm n dri board, drain tile and laid 18 inches of gravel in the same day. Has been raining some every day since and still not dry in spots. The brick ledge has washed off some as you can see streaks of the liquid asphalt here and there soaked through the fiberglass barrier board. Have trench footing so there has been standing water and concerned about the exterior wall footing joint. I cannot imagine the tuff and dri cured correctly down there. Contractor is saying it will be fine when it dries but it has been over a week and the curing time is supposed to be 24 hours. 1 local guy said they should remove the gravel, the drain, the board, everything and scrape soft spots and respray. Contractor resisting. Any thoughts?

Martin,
您的问题有点隐秘。当您写信时，“混凝土潜艇在一周前喷洒了我的地下室墙，”我不确定正在喷洒什么 - 喷洒泡沫绝缘或淋巴防水吗？- 或在壁的内部或外部喷洒物质的地方？
事实证明，我的谷歌搜索研究是Tuff-N-Dri是一个地下室防水系统。好的，我越来越接近解读您的问题。
这里有一个链接到Tuff-N-DRI安装说明. If you read them, you may be able to determine if your contractor followed the instructions. Concerning the brick ledge, note this disclaimer: "The TUFF-N-DRI System Limited Warranty covers neither the horizontal surface of the brick ledge nor the vertical wall surface above the ledge regardless of wall type."
Thank you Mr Holladay. My concern is the seam where the footing and wall meet on the exterior. As I understand, this is a primary place to seal, which makes sense, particularly for a trench footing that is level with the ground. The instructions for the waterproofing just says respray as needed. My question is as follows --- if the liquid membrane has been in water or moist at the footing for a week and is still not cured, can it still bond and be effective? There is no way to know on this end without removing the gravel and drain which is covering it up. Some parts of the wall membrane, especially ledges are still soft.
Martin,
I suggest that you direct your questions to a technical representative at Tremco. Here is the phone number:

Tremco说，很难与承包商交谈。我想我在您所说的“捕获22”中。
Martin Luther,
Can you describe a trench foundation. Is it one where the footing was poured without a form?
Yes, footing is poured into dug out trench, hard soil. No form used, which means the tuff n dri was sitting in water for a number of days which prevented curing during the expected 24 hr cure. Other horizontal places so wet in spots that membrane is like oil on fingertips.
这种问题是一个问题：为什么它根本坐在水中？如果适当地安装了平台，则应将水从立足点中取出。它们会排到白天吗？还是您会使用污水泵从立足点上取出水？
您的排水管需要低于内部平板的水平，这通常意味着旁边，而不是在其顶部。这阻止了沟渠的基础，除非在治愈后从底部的侧面去除土壤，以便可以将石头和排水板放在旁边。
也许您的基础墙壁和防水的草图可以帮助我们了解您的特定应用。
That said, generically, if the manufacturer requires 24 hours of curing before exposure to water and that condition was not met, make the contractor redo it. Why should you assume the risk of failure purely to save the contractor time and money? it was the contractor's election to race the rain.
排水管或排水材料罐，并且大多数通常设置在立足的顶部，因为地下的顶部在内部混凝土板的顶部以下4英寸。我的经验是，几乎所有防水泄漏都是由于页脚上的管道堵塞。应该让房主意识到，他们有义务检查基金会外围排水管的两端（至少每年）。这样做，您很可能永远不会在地下室里喝水。静水压力积累，并且始终采取阻力最小的路径。
我认为您的意思是，平板的底部应位于立足点顶部的顶部4英寸，而不是顶部。
Oops! My bad!!!
感谢彼得的有益评论。是的，流失是白天的，但是由于每端的管道都绑在锚螺栓上 - 我想我想将它们挡在障碍物上。我认为它的设计相当不错，坡度良好等，只是没有时间以正常方式治愈膜。我试图让他们将排水瓷砖放在顶部，但他们不会听到。
Martin Luther,
不幸的是,正如彼得说,周长drains on top of the footings means that vulnerable joint between the footings and foundation wall is frequently wet and susceptible to leaking. Trench drains should only be used when the soil has adequate drainage so that perimeter drains aren't needed, or the project is a slab on grade. Providing enough fill to bring the slab higher than the perimeter drains would be the best way to help alleviate the problem.
关于谁应该责备。从远处打电话很难。听起来像是您的GC，大概是负责外围排水系统的原因，以及混凝土的锻炼。
