Renovation work of a stone house due to dampness

Situated in Brittany, in the Côtes-d'Armor region, this stone building is bordered by a river. One day, the owners were astonished to discover signs of damp under the panelling in the south-west corner of the house. When they removed it, they found that all the woodwork and the parquet floor were heavily soaked with water.
This was caused by the high tides, which raise the level of the river up to 25 cm below the finished floor, exerting constant pressure on the wooden structure, which is constantly getting wet and can never really dry out.
Wishing to limit costs by carrying out the work themselves, I suggested an effective solution to the owners: a concrete slab ventilated using Igloos.
This easy-to-install interlocking system, onto which the concrete slab can be poured, provides an effective barrier against rising damp and ventilates the crawl space continuously thanks to air inlets to the south-east and an air outlet to the south-west located higher up to create a natural draught.
Once the concrete slab had been poured, the owners added rot-proof cork thermal insulation, before laying laminate flooring. The perimeter woodwork was completely redone, then painted to give an impeccable finish.
As a result of this work, the house has regained its original integrity and its occupants can once again enjoy the benefits of a new home.
