Why crushed limestone over crushed concrete?
In our previous crawl space reel, we shared how the 10-mil poly beneath this Heights home helps limit ground moisture from reaching the floor joists and living space above. This time, Jeannine explains the material holding that barrier in place.
The limestone serves as ballast, weighing down the poly. Its smaller, rounded edges help protect against punctures, which is why we chose it over the sharper edges of crushed concrete.
Watch the linked reel for a closer look at the v***r barrier installation and how these details work together beneath the home.
