Abstract
A system used to insulate soil, most practically in waste sites and the like, including a plurality of geoinsulation blankets and an anchoring means. Each blanket has a flexible plastic casing sealed around its perimeter with at least one air vent through it, a resilient insulation batt contained within the casing, and attachment means of the hook and loop type positioned along its perimeter to adjoin overlapping edges of blankets in the system.
Claims5
A geoinsulation blanket comprising:
- a flexible plastic casing having an outside perimeter consisting of two substantially opposing parallel edges, a front end, a back end, a top surface and a bottom surface;
- said casing being sealed around its outside perimeter to prevent the ingress and egress of air;
- said casing having at least one air vent through it to control the ingress and egress of air;
- said casing having a hook and loop type attachment means whereby a wide strip of the attachment means selected from the group consisting of
- a. hook and
- b. loop
- is fixedly mounted on the top surface and near the outside perimeter of the casing and along one parallel edge and one end, a narrow strip of the attachment means not selected for the top surface is fixedly attached on the bottom surface and near the outside perimeter along the opposite parallel edge and the opposite end;
- and,
- there is contained within said casing, a resilient insulation batt.
