This situation not only affects the bearing capacity of the soil, but also alters its stress-strain behavior due to the direct interaction between water and the soil matrix.<\/p>\n<p data-start=\"782\" data-end=\"1173\">More than a structural problem, this is a phenomenon <strong data-start=\"839\" data-end=\"864\">hydraulic-geotechnical<\/strong>, where water control is crucial to ensure system performance. In this context, the systems of <strong data-start=\"984\" data-end=\"1016\">subdrainage with geosynthetics<\/strong> have established themselves as an efficient, reliable and technically superior solution compared to traditional alternatives.<\/p>\n<h2 data-section-id=\"x1qx9v\" data-start=\"1180\" data-end=\"1236\">What does the water table in the subgrade imply?<\/h2>\n<p data-start=\"1238\" data-end=\"1549\">The water table corresponds to the zone where the soil pores are completely saturated. When this level coincides with the subgrade level or is close to the surface, unfavorable conditions are generated for the support of the pavement structure.<\/p>\n<p data-start=\"1551\" data-end=\"1635\">From a soil mechanics point of view, a high water table represents:<\/p>\n<ul data-start=\"1637\" data-end=\"1793\">\n<li data-section-id=\"ril0fu\" data-start=\"1637\" data-end=\"1679\">decrease in shear strength<\/li>\n<li data-section-id=\"hj74gs\" data-start=\"1680\" data-end=\"1722\">increased susceptibility to deformation<\/li>\n<li data-section-id=\"8yhkjo\" data-start=\"1723\" data-end=\"1745\">loss of rigidity<\/li>\n<li data-section-id=\"1anhp43\" data-start=\"1746\" data-end=\"1793\">unstable response during construction<\/li>\n<\/ul>\n<p data-start=\"1795\" data-end=\"1841\">In the long term, this phenomenon may result in:<\/p>\n<ul data-start=\"1843\" data-end=\"1993\">\n<li data-section-id=\"ahm8ub\" data-start=\"1843\" data-end=\"1889\">progressive loss of bearing capacity<\/li>\n<li data-section-id=\"j8iskv\" data-start=\"1890\" data-end=\"1919\">permanent deformations<\/li>\n<li data-section-id=\"18mnjfo\" data-start=\"1920\" data-end=\"1993\">accelerated pavement deterioration<\/li>\n<\/ul>\n<h2 data-section-id=\"182tf69\" data-start=\"2000\" data-end=\"2033\"><strong>Hydraulic system control<\/strong><\/h2>\n<p data-start=\"2035\" data-end=\"2157\">Since the origin of the problem is hydraulic, the solution must focus on controlling the water within the soil mass.<\/p>\n<p data-start=\"2159\" data-end=\"2172\">This involves:<\/p>\n<ul data-start=\"2174\" data-end=\"2348\">\n<li data-section-id=\"1d279tt\" data-start=\"2174\" data-end=\"2297\"><strong data-start=\"2176\" data-end=\"2206\">Capturing groundwater<\/strong>, reducing the water table elevation to reduce pore pressure in the subgrade<\/li>\n<li data-section-id=\"i5z6qt\" data-start=\"2298\" data-end=\"2348\"><strong data-start=\"2300\" data-end=\"2348\">Facilitate their evacuation in a controlled manner<\/strong><\/li>\n<\/ul>\n<p data-start=\"2350\" data-end=\"2535\">For this purpose, subdrainage systems designed to operate continuously within the soil and maintain controlled moisture conditions are implemented.<\/p>\n<h2 data-section-id=\"1mthsr4\" data-start=\"2542\" data-end=\"2585\"><strong>Subdrainage systems with geosynthetics<\/strong><\/h2>\n<p data-start=\"2587\" data-end=\"2710\">Modern subdrainage systems incorporate <strong data-start=\"2634\" data-end=\"2661\">drainage geocomposites<\/strong>, as <strong data-start=\"2668\" data-end=\"2683\">PERMADRAIN<\/strong>, known as geodrenes.<\/p>\n<p data-start=\"2712\" data-end=\"2763\">They are made up of three main components:<\/p>\n<ul data-start=\"2765\" data-end=\"2870\">\n<li data-section-id=\"77lrf4\" data-start=\"2765\" data-end=\"2797\">Superior nonwoven geotextile<\/li>\n<li

geotextile<\/li>\n<\/ul>\n<p data-start=\"2872\" data-end=\"3052\">This assembly configures a high hydraulic capacity system, capable of capturing and transporting water efficiently even under confinement.<\/p>\n<h2 data-section-id=\"16o3pdj\" data-start=\"3059\" data-end=\"3089\"><strong>HDPE perforated pipes<\/strong><\/h2>\n<p data-start=\"3091\" data-end=\"3228\">Perforated HDPE pipes, such as <strong data-start=\"3129\" data-end=\"3143\">DRAINPIPE<\/strong>, They complement the underdrainage system by acting as flow collectors.<\/p>\n<p data-start=\"3230\" data-end=\"3254\">Its main function is:<\/p>\n<ul data-start=\"3256\" data-end=\"3391\">\n<li data-section-id=\"1nifsha\" data-start=\"3256\" data-end=\"3301\">to receive the water captured by the geodrenes<\/li>\n<li data-section-id=\"1sp5gp6\" data-start=\"3302\" data-end=\"3341\">to discharge points<\/li>\n<li data-section-id=\"xs1stz\" data-start=\"3342\" data-end=\"3391\">maintain a continuous flow within the system<\/li>\n<\/ul>\n<p data-start=\"3393\" data-end=\"3418\">These pipes have:<\/p>\n<ul data-start=\"3420\" data-end=\"3516\">\n<li data-section-id=\"1s97hf9\" data-start=\"3420\" data-end=\"3449\">high mechanical strength<\/li>\n<li data-section-id=\"15pf4u5\" data-start=\"3450\" data-end=\"3470\">high durability<\/li>\n<li data-section-id=\"cqa54x\" data-start=\"3471\" data-end=\"3516\">compatibility with filter enclosures<\/li>\n<\/ul>\n<p data-start=\"3518\" data-end=\"3607\">This ensures its long-term performance.<\/p>\n<h2 data-section-id=\"izwt6v\" data-start=\"3614\" data-end=\"3657\"><strong>Advantages over traditional systems<\/strong><\/h2>\n<p data-start=\"3659\" data-end=\"3779\">Traditional systems, such as the <strong data-start=\"3696\" data-end=\"3716\">French drains<\/strong>, The filtering system consists of trenches filled with granular filtering material.<\/p>\n<p data-start=\"3781\" data-end=\"3856\">Although they have been widely used, they have important limitations:<\/p>\n<ul data-start=\"3858\" data-end=\"4062\">\n<li data-section-id=\"jhlk01\" data-start=\"3858\" data-end=\"3910\">dependence on the quality of the filter material<\/li>\n<li data-section-id=\"1s0lq38\" data-start=\"3911\" data-end=\"3959\">risk of clogging due to migration of fines<\/li>\n<li data-section-id=\"lmpdw8\" data-start=\"3960\"

data-end=\"4117\">In contrast, geosynthetic systems offer:<\/p>\n<ul data-start=\"4119\" data-end=\"4290\">\n<li data-section-id=\"iop88w\" data-start=\"4119\" data-end=\"4165\">controlled filtration by means of geotextiles<\/li>\n<li data-section-id=\"1nttsny\" data-start=\"4166\" data-end=\"4212\">high hydraulic capacity in a smaller space<\/li>\n<li data-section-id=\"pt19mj\"

data-start=\"4292\" data-end=\"4429\">This makes them a more efficient alternative from a technical and constructive point of view.<\/p>\n<h2 data-section-id=\"8dqre\" data-start=\"4436\" data-end=\"4449\"><strong>Conclusion<\/strong><\/h2>\n<p data-start=\"4451\" data-end=\"4587\">The presence of a <strong data-start=\"4470\" data-end=\"4510\">high water table in the
