Installation Guide for Rolled Erosion Control Products (RECPs) Including Mulch Control Nettings <br />(MCNs), Open Weave Textiles (OWTs), Erosion Control B-ankets (ECBs), and Turf Reinforcement Mats <br />(TRMs) <br />This document is intended to provide general guidelines for the installation of RECPs and does not supersede <br />manufacture's guidelines. The following sections summarize the general, accepted procedures for installation of <br />RECPs and provide basic guidance for slope and channel installations. Detailed design/installation information <br />should be obtained from the manufacturer. <br />General Procedure. Prepaze a stable and firm soil surface free of rocks and other obstructions. Apply soil <br />amendments as necessary to prepaze seedbed. Place fertilizer, water, and seed in accordance with manufacturer, <br />]ocaUstate regulations, or engineer/specifiers requirements. Typically, RECPs are unrolled pazalle] to the <br />primary direction of flow. Ensure the product maintains intimate contact with the soil surface over the entirety <br />of the installation. Do not stretch or allow materia[ to bridge over surface inconsistencies. Staple/stake RECPs <br />to soil such that each staple/stake is flush with underlying soil. Install anchor trenches, seams and temainal ends <br />as specified. <br />Install RECPs after application of seed, fertilizer, mulches (if necessary) and other necessary soil amendments, <br />unless soil in-filling of the TRM is required. For TRMs if soil in-filling, install TRM, apply seed, and other soil <br />amendments ]ightly brush or rake 0.3 to 0.7 in. (8 to 18 mm) of topsoil into TRM matrix to fill the product <br />thickness. If in-filling with ahydraulically-applied matrix or medium is required; install TRM, then install <br />hydraulically-applied matrix or medium at the manufacturer's suggested application rate. <br />Apply MCNs (Materials Type 1.A., 2.A., 3.A.) immediately after dry mulch application. <br />Anchor Trenches, Seams and Terminal Ends <br />(A) Upslope Anchor -utilize one of the methods detailed below for initial anchoring of RECPs <br />(1) Staples. Install the RECPs 3 ft. (900 mm) beyond the shoulder of the slope onto flat final grade. <br />Secure roll end with a single row of stakes/staples on 1 ft. (300-mm) centers. <br />(2) Anchor trench. Excavate a 6 in. by 6 in. (150 mm by 150 mm) anchor trench. Extend the upslope <br />terminal end of the RECPs 3 R. (900 mm) past the anchor trench. Use stakes or staples to fasten the <br />product into the bottom of the anchor trench on 1 ft, (300 mm) centers. Backfill the trench and <br />compact the soil into the anchor trench. Apply seed and any necessary soil amendments to the <br />compacted soil and cover with remaining 1 ft. (300 mm) terminal end of the RECPs. Fold product <br />over compacted soil in anchor trench to overlap downslope material. Secure temrinal end of RECPs <br />with a single row of stakes or staples on 1 ft. (300 mm) centers. <br />(3) Staple check. Construct astake/staple check slot along the top edge of the RECPs by installing <br />two rows of staggered stakes/staples 4 in. (100 mm) apart on 4 in. (100 mm) centers. <br />(4) Single net product anchor trencb. Excavate a 6 in. by 6 in. (150 mm by 150 mm) anchor trench. <br />Position roll such that the leading end of the roll is downslope and upside down. Apply seed and <br />necessary soil amendments. Extend product 1 ft. downslope of anchor trench and place material in <br />anchor trench (upside down). Secure terminal end and material in anchor trench with staples at 1 ft. <br />intervals. Fill anchor trench with soil and compact. Apply seed and necessary soil amendments to fill <br />placed in anchor trench. Move remaining roll over and downslope of anchor trench and proceed <br />unrolling RECP downslope (since roll was initially reversed, folding material over anchor trench will <br />result in the net side up, and rolling correctly downslope over the anchor trench). <br />(B) Seams -utilize one of the methods detailed below for seaming of RECPs <br />(1) Adjacent seams. Overlap edges of adjacent I2ECPs by 2 to 4 in. (50 to 100 mm) or by abutting <br />products as defined by manufacturer. Use a sufficient number of stakes or staples to prevent seam or <br />abutted rolls from separating. <br />Copyright ECTC 2006 ECTC, PO Box 18012, St. Paul, MN 55118 USA.
