HDPE biaxial geogrid imapangidwa ndi zinthu za polima za polyethylene yochuluka kwambiri. Iwo extruded mu pepala ndiyeno kukhomerera mu wokhazikika mauna chitsanzo, ndiye anatambasula mu gululi mu longitudinal ndi yopingasa malangizo. Polima yapamwamba ya geogrid ya pulasitiki imakonzedwa molunjika pakuwotcha ndi kutambasula popanga, zomwe zimalimbitsa mphamvu yomangirira pakati pa unyolo wa ma molekyulu kotero zimawonjezera mphamvu ya gululi.
