Damp Proofing Systems Comparison Chart

About 50-60 years after the construction of a building the original damp proof course (short: DPC) is likely to get damaged, for several reasons:

- Normal aging of the materials

- Corrosive effects of the ground salts

- Frost and temperature fluctuations

- Mechanical stress and vibrations

- Micro-organisms, moulds and bacteria

- Radioactive fallout

To reverse or fix the damage, several damp proofing systems have been developed. The table below summarizes the most important points of the main damp proofing systems:

Notes:

1.
The Aquapol system has successfully dried out walls as thick as 3m
2. Depending on the manufacturer or builder
3. Depending on technology and masonry structure
4. Does vary widely depending on the factors described on the previous pages
