Crawlspace Waterproofing

Are you about to embark on crawlspace waterproofing? When you hire a professional contractor to handle the waterproofing, there are certain steps that they will take to ensure the process is successful for the long term. One of these steps is a safety inspection of your crawl space.

A safety inspection of the crawl space is necessary before any work can begin in the space. This inspection not only helps the contractor determine if it is safe to enter the crawl space to begin the work, but also what preparations must be made before the actual waterproofing can be done.

The following are some health and safety considerations that the contractor must evaluate before they decide whether it is safe to enter the crawl space.

  1. Standing water

Are there pools of standing water in the space? Is the surface of the soil sticky or wet? Standing water and wet surfaces present various risks to those entering the crawl space. These include the risk of electrification as well as chemical contamination.

  1. Previously wet areas

Are there signs of areas that could have been wet in the past? Look for evidence of sewage spills, backups or burst pipes. This may have happened in the past and have dried up following repair of the sewer lines. Signs of this may include dried bits of toilet paper as well as dried waste.

Dried waste from the sewer can be a great hazard to health. The dried flakes can become airborne, carrying pathogens with them. The contaminated soil will need to be removed first and the area sterilized before work can begin. If needed, the sewer lines may be repaired to avoid future problems after crawlspace waterproofing.

  1. Debris

Is there excessive debris in the space? It is important to look out for debris such as nails, broken glass and splinters. These must be removed in order to avoid injuries. Debris such as torn insulation, shredded papers and gnawed wood splinters may indicate the presence of rodents and other pests. The space would therefore have to be treated to get rid of the pests.

  1. Mold infestation

Are there signs of mold in the space? These may include the presence of a musty odor or the sighting of fungi. Mold remediation must be done before waterproofing.

Inspectors will also be on the lookout for evidence of asbestos and structural integrity of the space.
