Create a chemical barrier against rising damp

Share this solution

The humidity that rises from the foundations, also called rising damp, causes the degrading or deterioration of the lower parts of the walls, and unhealthy environments inside dwellings.

In general we know that the wall presents this problem when we observe that the mortar or plaster are in bad condition.

The wallpaper is peeled off, the frieze wood has decayed, the paint is peeling, or there is a strong musty smell.

The solution to this problem consists of making a horizontal chemical barrier in the wall base with PROPAM® CREAM, water-repellent cream based on siloxanes in aqueous dispersion

PROPAM® CREAM is injected with a gun into a series of pre-drilled holes.

Remove the ceramic or wooden skirting board, and remove the degraded plaster or mortar until it reaches the original substrate,

Make holes of 12 mm in diameter, horizontal in the plane coincident with the joint. Drill at least one course with a maximum gap between holes of 10-12 cm.

Always drill a hole at the intersections between the horizontal and vertical joints. The depth of the hole will be that of the wall, leaving a shelf of between 2 and 4 cm with respect to the other face of the wall.


Unscrew the tube.

Insert the bag into the tube,

Place the nozzle and screw the tube. The two sharp elements of the nozzle will pierce the bag allowing the output of PROPAM® CREAM.

To facilitate execution, insert a flexible cannula into the tip of the nozzle.


Insert the tube to the bottom of the hole.

Completely fill the hole, leaving 1 cm free to the surface. Then plaster or apply a mortar without having to cover the holes.


  • It is recommended to carry out pre-tests on the substrates in order to observe the possible changes of tone.
  • The product has not been designed for application as surface impregnation.
