Do not install gutters inside the wall. An example of what this can lead to

There are design and architectural solutions in private houses, when the pipes of the drainage system pass inside the walls.

As an example. Yes, everything is hidden, there are no vertical pipes spoiling the facade. Also, from the passage of the drain through the walls - cannot be avoided in flat roof systems:

But many who use these techniques forget about one subtlety - winters with negative temperatures. The drain inside the wall is the place where the ice will constantly freeze. The heat from the wall and roof melts the snow, and when the temperature drops, ice freezes. You can safely predict that any drain will deform or even break the ice, and in the spring or during a thaw, melting of the ice will cause the walls to get wet.

With such a problem, one client contacted who wanted to waterproof and dry the wall. Because moisture even came through. But, as a rule, many want to get rid of the symptoms.

In conversation, I could not understand for a long time the reason for getting wet. When I understood the design of the problem area, the probable cause became clear. The client wanted to purchase liquid waterproofing for wall drainage.

There is a liquid waterproofing Polyfluid. The tool will be able to eliminate the symptoms of wet walls: prevent surface wetting of the wall (water repellent effect), dry it, bind water into a gel and prevent mold from falling out. And if you make injections of waterproofing through the holes in the wall, it will prevent molecular leakage of moisture.

But again, the logic of some is only to eliminate the symptoms without really finding out the reasons and solving the issue of the source of moisture. As with the freezing of walls - the fight is carried out by the method of treatment with an anti-mold agent.

In the client's question, the gutters should be examined. If damaged, fit a new pipe inside and lay the heating cable. Several variants:

Heating cable - mandatory for flat roof gutters. There will be no ice, it will not freeze and destroy the drain.

Ideally, if possible, then you need to bring the gutters to the facade. And in order not to leave in the winter with wet walls, you can drain them with liquid waterproofing by injection into the pits. I know Polyfluid. I saw how it works. Maybe there are some other analogues on the market ...
