The last thing anyone wants to deal with is sewage in their home, especially in a crawl space. So let Healthy Homes Remediation take care of your problem. The first thing we do is create a proper containment around the affected area. The liquid portion must be pumped out. Depending on the amount of raw sewage, an assessment will be made as to how much contaminated soil will be removed. Prior to removal the affected soil will receive an application of lime to achieve a ph level of 12 prior to removal. Once assessed amount of soil has been removed, an additional application of lime will be applied to area if in crawl space. Additionally if the affected area is in a crawl space, a minimum 6 ml vapor barrier will be placed.
