In this article, I would like to talk about a common situation that is an intractable problem for most waterproofing companies.
I mean the situation when the room is below ground level.
There is soil behind the wall and there is no possibility to excavate this soil and perform external waterproofing, which would obviously be the best solution.
You can see that we have two independent sources of moisture penetration into the wall. These are Rising Damp and Lateral Damp (moisture that penetrates the wall horizontally from the touching soil).
If we have two sources of moisture penetration, we have to find two different ways for solving this problems.

External Waterproofing | External Wall Waterproofing
We have talked about the methods of treatment of rising moisture so many times. You can find this information on our website. It is a case of Rising Damp.
Let’s talk about Lateral Damp
Proper and good preparation of surface is 50% of the labor intensity of all job and approximately 70% of the success of the job performed.
Apply the membrane over the existing damaged paint and in three months your membrane will peel or has a bubbly appearance, and just start to fall off the wall.

To get rid of Lateral Damp, we use an epoxy membrane – Moisture barrier to negative sides of underground wall. We apply 2, 3 or 4 layers. It depends on the situation.
Once this is done, you can leave the wall as is, you can render and paint it, or just paint. It depends on the preference of the customer.
I would like to clarify that we do not render or paint the walls.
Often, the water penetrates the wall in addition to moisture. This phenomenon significantly complicates and increases the cost of the treatment process.
If it happened, the technician decides to inject the Hydrophilic Polyurethane Injection Resin under high pressure and then to apply several layers of Fibre Reinforced Waterproofing Membrane, suitable for negative pressure, to the wall or only to apply a membrane to the wall.

The said membrane is “breathable”, i.e. it is not designed to resolve the problem of vapors and moisture penetration.
Therefore, after applying Waterproofing Membrane, suitable for negative pressure we apply a minimum of 2 more layers of epoxy membrane – Moisture barrier to negative sides of underground wall.

We pay special attention to work culture. We always leave the workplace absolutely clean. All the outer boundaries of the treated area are always neat and look good.
in contrast to the work that we see every day
