To dry up the walls and reduce capillary rise, we install a ventilated hedgehog, as well as draining insulation… 👇

• Thousands of stones !

Called a "hedgehog" in french, this is made of stones on edge, with a ventilation drain.
It is finished with washed 6/35 gravel and supplemented with an insulating and draining solution of expanded glass aggregates.
