Renovation of the crawl space

Ventilated crawl spaces may contain water, moisture or even building debris, compromising the indoor air quality.

The sandy or clayey soil on the bottom lifts up capillary moisture, increasing the moisture load on the crawl space. Together with organic matter, it contributes to the aforementioned problem. The crawl space should be odorless and dry in surface and air quality.

Ventilation may be inadequate both in terms of the air changing and the height of the space, sewer pipes may hang from their brackets or be completely against the ground and uninsulated, the plinth may be off the ground. There may be leaks at the joints between the floor tile and the plinth.

These shortcomings should be addressed without delay. The crawl space is cleaned of all debris and if necessary, a high-power vacuum is used to remove them to make sure the space is ventilated, clean and accessible for workers.  The aforementioned problems are corrected and if necessary, a filter cloth is installed on the bottom on moist or clayey soil for example. Finally, Leca gravel or washed crushed stone is blown over it.

Haulage problems can be solved with internal or external drainage cavities, possibly including pumping stations.

Ventilation can be improved with pipes or valves. For more difficult situations, a mechanical solution is used.

This project could be a part of the work done on drainage systems or just a single project.
