How To Install Geotextiles?

Step 1: Prepare the install area. This will typically involve a process of removing trees and brush from the top layer of soil and vegetation from the subgrade materials. Weak pockets of soil should be replaced with granular fill.


Step 2: Smooth and level the subgrade. All depression or humps within the subgrade should be removed.


Step 3: Place the geotextile in the prepared installation area. Fabric should be laid out according to engineered plans or site recommendations. Fabric should be stretched as tight and as flat as possible.


Step 4: Overlap adjacent rolls as specified for your site. If no instructions exist, fabric should be overlapped at a minimum or 12-18 inches.


Sewing or Overlapping-When installing a geotextile, adjacent fabric can either be sewn or overlapped. The following is from the AASHTO and is set as general guidelines for determining when to sew and when to overlap


Soil CBR> 3 -Minimum overlap of 0.3 to 0.45 m

Soil CBR 1-3 -Minimum overlap of 0.6-1

Soil CBR< 0.5 – Must be sewn
