ARCANE Industries offers several solutions to get rid of saltpetre through preventive or curative treatment:
- ARCASALTPETRE is a colorless waterproofing solution and fungicide that will limit the effects of saltpetre by destroying microorganisms (this solution must be coupled with one of the treatments below)
- The treatment against capillary rise ARCAFLUID is a waterproofing treatment for walls through injection. It blocks moisture at the bottom of the wall.
- Waterproofing for foundations ARCABASE is a bituminous coating that forms a flexible and rot-proof film. It blocks soil moisture.
How to get rid of saltpetre : preventive and curative treatment
This helps avoid infiltrations by capillarity. Upwelling from the soil by capillarity drain mineral salts such as nitrates that cause the formation of saltpetre. There are different techniques to limit these upwellings.
- Waterproof barriers: on must, at all costs, avoid indoor or outdoor sealants as well as outdoor floor waterproofing, and prefer:
- Injection of polymerizing products which, by gelling, clog capillary channels. Effectiveness depends on the proper diffusion of the ARCAFLUID product.
- Installation of a waterproofing membrane placed under the wall. This means that t is possible to intervene part by part on the entire wall.
- Drainage: It consists in placing a porous pipe in the ground, which will collect seepage along the building that is being treated. A few precautions need to be taken:
- Always place the draining device above the base level of the building’s foundations
- Make sure there is an adequate slope to drain water
- Protect the draining device from plant roots that may clog it by wrapping in geotextile
- Facilitate its regular maintenance by establishing access openings.
- Electromagnetic processes: To be effective, these delicate techniques should be applied to homogeneous masonry; monitoring of the installation should be done in time. Preliminary tests are useful. These techniques are suitable in the treatment of very sensitive edifices, including historical monuments.
- Passive or active electro-osmosis uses electromagnetic fields to reverse the polarity of the walls; this technique should avoid upwelling.
- Electrophoresis helps close the pores to prevent the upsurge of mineral salts.
