Continuous-filament fabric generally provides higher tensile strength and modulus at the same mass.<\/p>\n<\/details>\n<details>\n<summary>What are typical technical values for a 400 g\/m\u00b2 grade?<\/summary>\n<p>Typical supplied values are tensile strength \u2265 12.5 kN\/m, CBR puncture strength \u2265 2.0 kN, trapezoid tear strength \u2265 0.33 kN and thickness \u2265 3.0 mm. Final acceptance follows the mill certificate and project test method.<\/p>\n<\/details>\n<details>\n<summary>What functions does staple-fiber geotextile provide?<\/summary>\n<p>It provides separation, filtration, drainage, reinforcement and protection, and can cushion geomembranes against puncture and stress concentration.<\/p>\n<\/details>\n<details>\n<summary>Which projects commonly use it?<\/summary>\n<p>Common uses include road and railway subgrades, airfields, levees, canals, landfills, tailings ponds, artificial lakes, basement protection and landscaping.<\/p>\n<\/details>\n<details>\n<summary>How should the mass grade be selected?<\/summary>\n<p>Use lighter grades for general separation, medium grades for road filtration and drainage, and heavier grades for soft ground, landfills, tailings facilities and geomembrane protection. Always follow the design documents.<\/p>\n<\/details>\n<details>\n<summary>How are filtration criteria checked?<\/summary>\n<p>Retention, permeability and clogging resistance should be checked against the protected soil gradation. Site-specific testing is recommended for gap-graded or piping-prone soils.<\/p>\n<\/details>\n<details>\n<summary>How is it used with geomembranes?<\/summary>\n<p>It is installed above or below HDPE or LLDPE geomembranes to reduce puncture and localized stress. Heavier grades are normally selected where cover aggregate or high contact pressure is expected.<\/p>\n<\/details>\n<details>\n<summary>What are the key installation requirements?<\/summary>\n<p>Level the subgrade, remove sharp objects, lay the fabric without tension with suitable slack, overlap or sew joints as specified, cover promptly and keep machinery off the fabric until a protective layer is placed.<\/p>\n<\/details>\n<details>\n<summary>How are joints and damaged areas handled?<\/summary>\n<p>Ordinary areas can be overlapped; demanding work may require sewn seams. Repair damage with matching material extending at least 30 cm beyond the affected edge, unless the project specification requires more.<\/p>\n<\/details>","protected":false},"excerpt":{"rendered":"<p>Needle-punched PET or PP staple-fiber nonwoven geotextile with high elongation, filtration and cushioning performance for separation, drainage and geomembrane protection.<\/p>","protected":false},"featured_media":1334,"template":"","meta":{"_gspb_post_css":"","_taiji_application_gallery":""},"product_brand":[],"product_cat":[25],"product_tag":[],"class_list":["post-1326","product","type-product","status-publish","has-post-thumbnail","product_cat-nonwoven-geotextiles","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/taijigeo.com\/ru\/wp-json\/wp\/v2\/product\/1326","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/taijigeo.com\/ru\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/taijigeo.com\/ru\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/taijigeo.com\/ru\/wp-json\/wp\/v2\/media\/1334"}],"wp:attachment":[{"href":"https:\/\/taijigeo.com\/ru\/wp-json\/wp\/v2\/media?parent=1326"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/taijigeo.com\/ru\/wp-json\/wp\/v2\/product_brand?post=1326"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/taijigeo.com\/ru\/wp-json\/wp\/v2\/product_cat?post=1326"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/taijigeo.com\/ru\/wp-json\/wp\/v2\/product_tag?post=1326"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
