THE GEOGRID MYTH <br />Woven Geotextiles—why they really work better! <br />For subgrade stabilization applications where weak <br />subgrade conditions exist, geognds are limited In <br />their effectiveness due to their low tensile strength, <br />inability to separate and provide filtration., expensive <br />mechanical connectors, and high cost In subgrade <br />stabilization applications the product that works <br />best is often a woven geotextde Woven geotextlles <br />comb ne the properties of high tenst'e strength and <br />modulus, and high confinement, in iddltfon to the!r <br />auiltty to act as a filter and separator Woven <br />geotextlles can also oe searned Together to c,reato <br />uniform high strength !n al dfrectfors, I.1 tact, if you <br />lock at any subg adF stabtifzation ahpllcatron, <br />woven geotexhfcs v,nll always out perform geogrfds. <br />lechnicatly and ecor:omically <br />Gc xi,39 fn ;ht; of ovi sJ•1 SutArdn•' 91•auq^ :•.�i�c <br />wavy, I wt! p,mme 3rd 1 irr A ,r <br />A Look at the Facts tells you why! <br />Properties of Mirafi HP Woven Geotextiles Versus Biaxial Geogrids, <br />MIRAFI Biaxial Geogrid <br />MIRAFI <br />Biaxial Geogrid <br />Units HP370 Type 1 <br />HP570 <br />Type 2 <br />MD XD <br />MD XD <br />tern ile Strencth <br />Ultfmatc, Ibs'h 2700 910 1410 <br />4800 <br />1:,78 21B8 <br />5°1r Strlin Ibsl!t 1350 62C 890 <br />2400 <br />820 13.10 <br />�`, Strain Ibs!ft 540 300 445 <br />960 <br />380 595 <br />lrneractfon - G 0.8 08 <br />0.95 <br />08 <br />Seuaratfon/l'iltrar,or, Excellent None <br />Excellent <br />None <br />i tte­.o Props •^rdS wF re obtivr;e,: rrc n, ,t.a nec m.�n„ract rer,' bterar.,n' and a< tua; test orogr.,ms <br />Technical Comparison -- When you Took at the key <br />product properties required of a geos�ntnetfc for <br />s,rograde staoil,zanon anphcatfons--hig"f :ensile <br />Strengttr and rrionulus, high conffron,era, f Il,alion. <br />separation. and seam strength—HP Geotextk,s ia• <br />exc e,Fo 1huse !or CPognds in evar; calegory <br />In ":very c.alegor; Miraff HP vvo•.er, jeotext+fes <br />exceed the procerlies Of geognds ef'er L a fact_a <br />012 or more In addition woven geotcxt es pros du <br />seoaration and filtration functions, a -i :::an provioe <br />multf-dfreclfonal strengths n excess of 00' <br />pounds per toot. none of which are possible vrtn <br />geogrfds <br />Economical Comparison - The matPnal cost o; the <br />Mlrai, HP woven geo,ext,les are 20 to 5J percent <br />less tI an that of the geoyrfd alone they are a.ail- <br />able in wider roll vv,dihs and can t)e Seamed <br />together to reduce c verlai, regi::ren-ierts <br />Mraff HP neo'extr!es save'uYre nr,7 n'onev_ c.ver <br />geogr ds any ,;ay you loo, at t <br />THE BOTTOM LINE - While TC Mlraff manufactures <br />both woven and non -woven geotextlles and <br />geogrfds, if you need a geosynthetic product <br />for subgrade stabilization applications. we <br />recommend woven geotextlles every time. <br />Page 2.05.3(3)-28 January 2016 (TR -70) <br />
