WALKWAYS <br />PROBLEM; <br />Provide an all-weather natural-look walking; <br />riding path surface with reduced maintenance. <br />SOLUTION: <br />TREVIRA- Spunbond is placed on top of grad ­ <br />ed, compacted subsoil. A minimum of 4 inches <br />of fine, compactable stone is placed directly on <br />top of TREVIRA Spunbond and rolled in. To con <br />trol movement of stones in the lateral direction <br />either landscape timbers, concrete or other cur <br />bing should be used. TREVIRA Spunbond pro <br />vides a unigue combination of separation <br />filtration, planar flow and tensile reinforcement <br />for this system, which allows for several <br />methods of drainage to be incorporated. <br />Crushed Aggregate <br />•>0.1 <br /><5. o f U • 0 . <br />* C o e 0 .1 <br />Trevira® <br />Spunbond <br />Landscape <br />Timber <br />Figure 9 — TREVIRA SpunDond for Walkways <br />BENEFITS: <br />Prevents the intermixing of subsoil and crush­ <br />ed aggregate thereby reducing the destruction <br />caused by heaving within the aggregate layer <br />while maintaining the permeability of the ag ­ <br />gregate. <br />WEED CONTROL (MULCH) <br />PROBLEM: <br />Reduce weed growth in unwanted areas and <br />allow total permeation of water. <br />SOLUTION: <br />Place TREVIRA Spunbond under a minimum of <br />4 inches of stone, pine needles, tree bark, etc. <br />Pine Needles or <br />Pine Bark or <br />Stone <br />4" Thick <br />♦ <br />Is <br />Pigure 10 — TREVIRA SounDond tor We.-d Control <br />BENEFITS: <br />TREVIRA Spunbond will retard weed growth <br />and allow vertical and horizontal passage of <br />water and chemicals for plant and/or tree <br />feeding without deterioration or “floating ”. <br />RETAINING WALLS <br />PROBLEM; <br />Eliminate loss of soil through voids in retaining <br />walls made of wood, concrete block, stone, etc. <br />SOLUTION I; <br />Place TREVIRA Spunbond directly between <br />wall composite and backfill. <br />Backfill <br />Block <br />Weep hole <br />I •; ■ “ <br />- <br />-■** -c.'^Trevira* <br />Spunbond <br />(KF' Gravel <br />Note: inetell <br />Footing—'Collector <br />pipe <br />water barrier <br />on all backwallB. <br />FiQure ■ 1 — TREVIRA Sounpond for Retaining Walls <br />€ <br />C <br />8/02 Rev 2/83 la -4
