ᐅ How to Properly Install a Drainage Membrane at the Foundation Base – Any Experience?

Hi everyone,

I am planning to install a dimple membrane around my house. I asked three acquaintances who are supposed to be familiar with this, but I got what felt like four different opinions.
How is the dimple membrane installed correctly? Which side should be fixed where, and what materials are needed? Does anyone have experience with this?
The reference point for the height is my front door. The height of the dimple membrane should be 1 meter (3.3 feet).

Best regards & thanks

Whether the studs face the building component or the soil depends on the intended function of the drainage membrane. Both options are possible.

Studs facing the building component: Better ventilation to prevent moisture
Studs facing the soil: Better protection of the building component

The method of attachment naturally depends on the building component. What is beneath the base plaster? Insulation boards? Poroton blocks? Calcium silicate bricks?

Depending on this, you may also need to use a drainage membrane with fleece to avoid damage. For example, if the studs face the building component and insulation boards are underneath.

Hello,

regarding the dimpled membrane and its installation, I received an information sheet from my construction company. Maybe it will be helpful.

Best regards

Axel

Depending on that, you may also need to use a studded membrane with a fleece layer to avoid damage, for example if the studs face the building component and there are insulation panels underneath.

I have 12cm (5 inches) of Styrofoam insulation and 26cm (10 inches) Ytong blocks. The studded membrane is meant for protection, as a splash guard.

An acquaintance said the studded membrane should be fixed to the facade, while another said it should be placed at the bottom on the foundation and not on the facade.

I had also bought nails, but we didn’t need them.
We only needed about 30cm (12 inches), which we placed in front of the bitumen coating of the base plaster and then carefully filled in gravel. The dimple membrane is tightly secured there by the gravel.

What I have found so far always refers to the basement, without 12cm (5 inches) of insulation.
