Rising Damp

What is rising damp?

A moisture problem caused by water in the ground being drawn upwards inside the wall by capillary force. It is usually seen on ground floors and in basements; salt deposits at the base of the wall, blistering paint and crumbling plaster are its most typical signs.

How can I tell if the damp on my wall is rising damp?

The signs: a damp stain reaching 50-150 cm above the base of the wall, white salt deposits, blistering paint and a musty smell. The damp increases in rainy periods. If it starts at the base of the wall and climbs upwards, it is most likely rising damp.

How do you solve a damp problem in a basement?

On basement walls set into the soil, water gets in actively from outside; DampStop injection is not the solution. PU injection (E101 Pur In) and crystalline waterproofing (N102 Crystal 2K) works are planned on the basis of an expert assessment. On ground-floor walls with no contact with the soil, DampStop + HydroFix are applied, with the Damp Box (Nem Kutusu) if needed.

Can a damp problem be fixed with paint?

No, anti-damp paint is only a temporary fix and does not solve the underlying problem. For a permanent solution, the source of the damp must be cut off with DampStop injection and the surface renewed with HydroFix damp-proofing plaster. The correct order: first strip the old plaster and apply HydroFix; once the plaster has dried (24–48 hours), inject DampStop.

What can be done about damp problems in a rented home?

First identify the source; with condensation, better ventilation and heating are often enough. For damp rising from the base of the wall, the permanent fix is HydroFix + DampStop applied to the wall (with the landlord’s consent). The Damp Box does not replace this: it carries water reaching the foundations and rising in the columns back into the ground and is part of the triple system; it plugs into a socket and can move out with you.

DampStop

How is DampStop injection applied?

Holes are drilled about 10 cm above floor level at 10 cm intervals, angled 30–45° downwards. The holes should be about 80% (4/5) of the wall thickness deep. The prepared DampStop mixture is poured into the holes with a funnel; no pump is needed (a low-pressure pump is optional, only for professional, fast application).

Full answer
HydroFix

Does HydroFix completely block damp and moisture?

Yes, it cuts off capillary water passage. However, where there is negative water pressure, such as on basement walls set into the soil, HydroFix alone is not the solution; PU injection (E101 Pur In) and crystalline waterproofing (N102 Crystal 2K) are needed.

Full answer
Damp Box

What is the Damp Box and how does it work?

A drying device that uses a very low-frequency electromagnetic wave to carry water reaching the foundations and rising in the columns back into the ground. On the walls it works with DampStop + HydroFix as the triple system; it plugs into a socket, uses 3–5 W and needs no chemicals or demolition.

Damp Box

Can the Damp Box be used together with DampStop injection?

Yes, this is recommended. DampStop and HydroFix work only in wall elements; the Damp Box carries water reaching the foundations and rising in the columns back into the ground. Used together (the triple system), the three solve rising damp in walls, foundations and columns.
