This way many solutions can be made by using ecological and modern technology.<\/p>\n<h3>Good planning in the beginning of the project provides the best qualifications<\/h3>\n<p>Horizontal directional drilling is already much more common than earlier. The reason why it is not yet more widely used are the rooted habits of infra designers to use old methods like using excavators to do the digging and opening trenches. Horizontal directional drilling is today more and more used in pulling pipes and cables. It is important in the future to consider horizontal directional drilling as an option in infra projects because it is a progressive method, environmentally and landscape friendly and quick method which is well suited for different soil types.<\/p>\n<h3>Horizontal directional drilling enables quick and efficient solutions<\/h3>\n<p>Horizontal directional drilling is efficient, environmentally friendly, quick and economical way to carry out work in different kinds of soils. In addition, directional drilling is a landscape friendly method and risks of damaging ground water are small.<\/p>\n<p>Directional drilling can be used to drill up to 1500 meters. Most cost effective are drillings to 500 meter or less.<\/p>\n<p>Horizontal directional drilling is a sensible alternative in targets, where digging is impossible or the traffic arrangements and\/or finishing work cause big costs.<br \/>\nHorizontal directional drilling is a guidable drilling method, which enables underground infra installation without disturbing excavations and breaking of surfaces.<\/p>\n<p>Method is well applicable in city sites, nature reserve areas and other sites, where digging is impossible or unwanted.<\/p>\n<p>HDD guided directional drilling is well suited for drilling under rivers, roads, railways, runways and natural obstacles in the nature. The deeper the drilling and the softer the conditions, the better the competitiveness compared to other methods.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element

In soft soils the pilot hole is drilled by using high pressure flushing and similarly in hard soil by using a so-called mud motor.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-9d1b398\" data-id=\"9d1b398\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-77c0170 elementor-widget elementor-widget-heading\" data-id=\"77c0170\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Stage 2<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-269fc72 elementor-widget elementor-widget-image\" data-id=\"269fc72\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"969\" height=\"429\" src=\"https:\/\/lannenalituspalvelu.fi\/wp-content\/uploads\/2021\/05\/Suuntaporaus-vaihe-02.jpg\" class=\"attachment-full size-full wp-image-1322\" alt=\"\" srcset=\"https:\/\/lannenalituspalvelu.fi\/wp-content\/uploads\/2021\/05\/Suuntaporaus-vaihe-02.jpg 969w, https:\/\/lannenalituspalvelu.fi\/wp-content\/uploads\/2021\/05\/Suuntaporaus-vaihe-02-768x340.jpg 768w\" sizes=\"(max-width: 969px) 100vw, 969px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c7bd0e5 elementor-widget elementor-widget-text-editor\" data-id=\"c7bd0e5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>When the target pit has been reached, the measuring sensor and drill head are removed and they are replaced by an reaming tool and rotatable connection, which is connected to the product pipe.
