What it is

What is the BOX-S-GEO?

The BOX-S-GEO (also searched as "geo box") is the device developed and distributed by Geo Portugal to treat rising damp in walls — groundwater that rises by capillary action and causes salt efflorescence, mould and rendering decay at the base of walls.

How it works

How the BOX-S-GEO works

The BOX-S-GEO acts on the natural magnetic field to reverse the capillary rise of water and send it back to the ground. The wall dries progressively and the source of the problem stops feeding the salts and mould.

  • Non-destructive installation — no drilling, no hacking off render
  • Self-powered — no electricity, no wires, no consumption
  • No chemicals or resins in the wall
  • Monitored, measured drying over time, with an measured monitoring
