GeoTech Insulated Drainage Panel was the first of its kind as a sheet drain when it was first offered in 1983, and continues to have unique advantages over other systems that have emerged since then:

• It is compressible, and can serve as a compressible inclusion
• It is an insulator, having an "R" value of 3.5 per inch.
• It can accommodate ANY geotextile that may be required for a given soil type.

The drainage panels are manufactured in sheets measuring 4' x 4' on edge, and in thicknesses varying from 2 inches up to 24 inches. They are temporarily fixed to the below grade wall with either an adhesive or "Stick Clips" (both discussed under the "Miscellaneous" link to the left).

The Insulated Drainage panels have been used successfully to relieve hydrostatic pressure and earth pressure in the following type of applications Highway and Landscape Retaining Walls Bridge Abutments Commercial and Residential Foundation Walls
