They’re doing what to the hole in the ground? Part Three: Cushion Layer

Landfills are highly engineered structures designed to protect the environment from society’s trash. Over the course of the last few months, we’ve been sharing information on how a landfill is constructed as Rumpke prepares a section of its property for trash disposal. 

We’ve already skillfully placed clay and a high density polyethylene (HDPE) liner in the 14-acre section of our site, and recently we’ve installed our third protective layer – a cushion layer.  

Cushion Layer

The cushion layer is a geo-textile, which is a felt like material that is designed to protect the HDPE liner.

Similar to how the HDPE was deployed, the geotextile is rolled out in sections. The sections are then sewn together with a modified sewing machine.

With the cushion layer now in place, we are nearing the end of our project. Watch for our fourth and final blog about landfill construction in the coming weeks.
