<br />INSTALLATION GUIDELINES <br />FOR LANDLOKO TRMs..AND PYRAMAT® HPTRMs . <br />INSTALLATION ON STABLE SOIL SLOPES <br />? Excavate a 12 x 6 in (300 x 15 mm) minimum longitudinal anchor trench 2.3 ft (600-900 mm) over crest of slope (see Figure 2). <br />? Install top end of mat'into trench and secure to bottom using suggested ground anchoring devices (see Tables 1 and 2 on page 7) <br />spaced every 12 in (300 mm) minimum. BaMll and compact soil Into trench (see Figure 2). <br />? Unroll mat down slope. Uridlok• 1051 shall have the geotextlie on bottom. <br />? Overlaps shall be 6 in (150 mm) minimum and anchored every 18 in (450 mm) minimum along the overlap. Secure using <br />suggested ground anchoring devices shown in Table 1 for appropriate frequency and pattern, Overlaps are shingled away from <br />prevailing winds (see Figure 1). <br />? Unroll mat in a manner to maintain direct contact with soil. Secure mat to ground surface using ground anchoring devices <br />(see Table 1). Anchors shall be placed in accordance with the Anchor Pattern Guide on page 7. <br />? Excavate a 12 x 6 in (300 x 150 mm) key anchor trench at toe of slope (see Figure 3). <br />? Place bottom end of mat Into key anchor trench at toe of slope and secure to bottom of trench using suggested ground anchoring <br />devices (see Tables 1 and 2) spaced every 12 in (300 mm) minimum. Backfill and compact mil into trench (see Figure 3). <br />/ If the potential for standing and/or flowing water exists at the toe of slope, the key anchor trench at the toe detail (see Figure 3) <br />is not sufficient Consult the project engiineer for the appropriate detail. <br />? Irrigate as necessary to establish/maintain vegetation. Do not over-irigate. <br />Longitudinal • . _ <br />anchor trench <br />• o 0 0 O <br />0 0 0 o p <br />O G G G p p <br />o?j?
