This technique creates a permeable \u201cpath\u201d that the water will follow until it slowly dissipates.<\/p>\n<p style=\"text-align: left;\">In order to construct an effective trench, an excavation must be created in the ground between 500 centimetres and a maximum of 1 metre wide; the depth depends on the running surface. <strong>Drainage trenches<\/strong> are in fact divided into:<\/p>\n<ul class=\"list-marked\">\n<li>surface: maximum depth of 5 metres;<\/li>\n<li>deep: the <strong>trench excavation<\/strong> can be as deep as 25 metres.<\/li>\n<\/ul>\n<p style=\"text-align: left;\">In order for a trench to drain soil, non-woven fabric (or geotextile) must be placed around the trench to prevent soil from clogging the trench. It must then be filled with coarse-grained material (sand or gravel) so that water can pass through it. Finally, the excavation must be covered with waterproof material.<\/p>\n<p style=\"text-align: left;\">The choice of backfill material is crucial to the success of the drainage system as it is the contrast in permeability between the trench soil and the surrounding soil that determines the direction of the water and thus its dispersion.<\/p>\n<p style=\"text-align: left;\">To facilitate the inflow of water into the trench and its subsequent dispersion, <a href=\"https:\/\/polieco.com\/en\/prodotti\/drenopal\/\" target=\"_blank\" rel=\"noopener\">cracked pipes<\/a> and\/or <a href=\"https:\/\/polieco.com\/en\/prodotti\/rausikko\/\" target=\"_blank\" rel=\"noopener\">dispersing cells<\/a> can be inserted into the excavation.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><a class=\"button button-darker\" href=\"https:\/\/polieco.com\/en\/type\/drainage-and-dispersion-en\/\" target=\"_blank\" rel=\"noopener\">Discover the drainage systems<\/a>\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 <a class=\"button button-darker\" href=\"https:\/\/polieco.com\/en\/the-importance-of-draining-soils\/\" target=\"_blank\" rel=\"noopener\">Why you should drain land<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Nowadays, we are witnessing a push for urbanisation due to strong industrial and civil expansion, which on the one hand [&hellip;]<\/p>\n","protected":false},"author":15,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[149],"tags":[],"class_list":["post-11024","post","type-post","status-publish","format-standard","hentry","category-drainage-and-dispersion"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.0 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Guide to Creating a Drainage Trench | Polieco Group<\/title>\n<meta name=\"description\" content=\"Creating a trench is the most frequently used way of draining land.
