1. Process for introducing a liquid to prevent rising damp in masonry, the water-repellent or hydrophobic liquid being supplied to the wall by way of perforated tubes using a compressor, characterised in that the liquid is supplied in regular pulses ; these start from the compressor and a metering device which are controlled by an electronic, hydraulic or pneumatic device or manually, it being possible for the strength of the pulses and the intervals between the individual pulses for supplying the liquid which is to be supplied to the wall to be variably adjusted or controlled according to the least porous zones of the wall and, depending on the nature of the wall, the metering device being adjusted in such a manner that it releases that amount of water-repellent or hydrophobic liquid per unit of time which corresponds to the normal absorption of the wall and which the least porous part of the wall can absorb. |
