If the soil isn\u2019t stable, there\u2019s a risk of settlement, cracks, and costly repairs. A site investigation provides peace of mind by determining the actual bearing capacity and identifying risks\u2014such as groundwater, frost-prone areas, or soft soil layers\u2014early on. This gives you clarity, allows you to choose the appropriate foundation, and enables you to plan your construction project reliably\u2014both technically and financially\u2014from the very beginning.   <\/span><\/p><p><span style=\"font-weight: 400;\">In this blog post, you\u2019ll learn what a site investigation is, how it\u2019s conducted, and what happens if you skip it. We\u2019ll also provide an overview of costs, the legal framework, and the most important reasons why an expert report is a good idea. This will give you a solid foundation for making informed decisions about your construction project.  <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-219994a elementor-toc--minimized-on-tablet elementor-widget elementor-widget-table-of-contents\" data-id=\"219994a\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;headings_by_tags&quot;:[&quot;h2&quot;,&quot;h3&quot;,&quot;h4&quot;],&quot;exclude_headings_by_selector&quot;:[],&quot;no_headings_message&quot;:&quot;No headings were found on this page.&quot;,&quot;marker_view&quot;:&quot;numbers&quot;,&quot;minimize_box&quot;:&quot;yes&quot;,&quot;minimized_on&quot;:&quot;tablet&quot;,&quot;hierarchical_view&quot;:&quot;yes&quot;,&quot;min_height&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:[]},&quot;min_height_widescreen&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:[]},&quot;min_height_laptop&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:[]},&quot;min_height_tablet_extra&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:[]},&quot;min_height_tablet&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:[]},&quot;min_height_mobile&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:[]}}\" data-widget_type=\"table-of-contents.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-toc__header\">\n\t\t\t\t\t\t<h4 class=\"elementor-toc__header-title\">\n\t\t\t\tTable of Contents\t\t\t<\/h4>\n\t\t\t\t\t\t\t\t\t\t<div class=\"elementor-toc__toggle-button elementor-toc__toggle-button--expand\" role=\"button\" tabindex=\"0\" aria-controls=\"elementor-toc__219994a\" aria-expanded=\"true\" aria-label=\"Open table of contents\"><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-chevron-down\" viewBox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M207.029 381.476L12.686 187.132c-9.373-9.373-9.373-24.569 0-33.941l22.667-22.667c9.357-9.357 24.522-9.375 33.901-.04L224 284.505l154.745-154.021c9.379-9.335 24.544-9.317 33.901.04l22.667 22.667c9.373 9.373 9.373 24.569 0 33.941L240.971 381.476c-9.373 9.372-24.569 9.372-33.942 0z\"><\/path><\/svg><\/div>\n\t\t\t\t<div class=\"elementor-toc__toggle-button elementor-toc__toggle-button--collapse\" role=\"button\" tabindex=\"0\" aria-controls=\"elementor-toc__219994a\" aria-expanded=\"true\" aria-label=\"Close table of contents\"><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-chevron-up\" viewBox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M240.971 130.524l194.343 194.343c9.373 9.373 9.373 24.569 0 33.941l-22.667 22.667c-9.357 9.357-24.522 9.375-33.901.04L224 227.495 69.255 381.516c-9.379 9.335-24.544 9.317-33.901-.04l-22.667-22.667c-9.373-9.373-9.373-24.569 0-33.941L207.03 130.525c9.372-9.373 24.568-9.373 33.941-.001z\"><\/path><\/svg><\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<div id=\"elementor-toc__219994a\" class=\"elementor-toc__body\">\n\t\t\t<div class=\"elementor-toc__spinner-container\">\n\t\t\t\t<svg class=\"elementor-toc__spinner eicon-animation-spin e-font-icon-svg e-eicon-loading\" aria-hidden=\"true\" viewBox=\"0 0 1000 1000\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M500 975V858C696 858 858 696 858 500S696 142 500 142 142 304 142 500H25C25 237 238 25 500 25S975 237 975 500 763 975 500 975Z\"><\/path><\/svg>\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-90ea75a elementor-widget elementor-widget-text-editor\" data-id=\"90ea75a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><b>Key Points About the Costs of a Site Investigation:<\/b><\/p><p><span style=\"font-weight: 400;\">A site investigation determines whether the soil on your property is suitable for your construction project.

In high-risk areas (e.g., those with groundwater, slopes, or suspected contaminated sites), the building authority may mandate an expert report.   <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t<details id=\"e-n-accordion-item-1273\" class=\"e-n-accordion-item\" >\n\t\t\t\t<summary class=\"e-n-accordion-item-title\" data-accordion-index=\"4\" tabindex=\"-1\" aria-expanded=\"false\" aria-controls=\"e-n-accordion-item-1273\" >\n\t\t\t\t\t<span class='e-n-accordion-item-title-header'><div class=\"e-n-accordion-item-title-text\"> Who conducts a site investigation? <\/div><\/span>\n\t\t\t\t\t\t\t<span class='e-n-accordion-item-title-icon'>\n\t\t\t<span class='e-opened' ><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"40\" height=\"21\" viewBox=\"0 0 40 21\" fill=\"none\"><path d=\"M19.0945 8.00344L19.0945 -2.742e-06L-8.07685e-08 19.1522L0.251212 19.3858L24.7999 19.3858L24.7999 15.8719L30.6203 21L40 21L40 20.8131L20.5077 1.5052L20.5077 13.8788L12.7611 13.8788L19.0945 8.00344Z\" fill=\"#0E1D29\"><\/path><\/svg><\/span>\n\t\t\t<span class='e-closed'><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"40\" height=\"21\" viewBox=\"0 0 40 21\" fill=\"none\"><path d=\"M20.9055 12.9966L20.9055 21L40 1.84777L39.7488 1.61421L15.2001 1.61421L15.2001 5.12807L9.37967 -1.33846e-06L0 -1.74846e-06L-8.1706e-09 0.18692L19.4923 19.4948L19.4923 7.12118L27.2389 7.12118L20.9055 12.9966Z\" fill=\"#0E1D29\"><\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t<div role=\"region\" aria-labelledby=\"e-n-accordion-item-1273\" class=\"elementor-element elementor-element-e7f9492 e-con-full e-flex e-con e-child\" data-id=\"e7f9492\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-03ec432 p-top elementor-widget elementor-widget-text-editor\" data-id=\"03ec432\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">Geologists, geotechnical engineers, or soil investigation experts are responsible for this work. Often, a publicly appointed geotechnical expert conducts the investigation, particularly for more complex construction projects. They work with drilling crews who take soil samples on site and perform cone penetration tests to measure bearing capacity. These samples are then analyzed in the laboratory.

Unstable soil can lead to settlement, which can cause cracks in the masonry, crooked doors and windows, or even structural problems. A high water table, for example, can\u2014without a preliminary inspection\u2014make it necessary to retrofit the basement with waterproofing, which costs around \u20ac35,000 for a 100 m\u00b2 area. The expert report, costing just a few thousand euros, can therefore save you from damages in the five- to six-figure range.   <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0ef092c elementor-absolute elementor-hidden-mobile elementor-hidden-tablet elementor-widget elementor-widget-image\" data-id=\"0ef092c\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_position&quot;:&quot;absolute&quot;,&quot;motion_fx_motion_fx_scrolling&quot;:&quot;yes&quot;,&quot;motion_fx_translateY_effect&quot;:&quot;yes&quot;,&quot;motion_fx_translateY_speed&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:4,&quot;sizes&quot;:[]},&quot;motion_fx_translateY_affectedRange&quot;:{&quot;unit&quot;:&quot;%&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:{&quot;start&quot;:0,&quot;end&quot;:100}},&quot;motion_fx_devices&quot;:[&quot;widescreen&quot;,&quot;desktop&quot;,&quot;laptop&quot;,&quot;tablet_extra&quot;,&quot;tablet&quot;,&quot;mobile&quot;]}\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"111\" height=\"851\" src=\"https:\/\/thade-gerdes.de\/wp-content\/uploads\/2024\/08\/BG-L.png\" class=\"attachment-full size-full wp-image-4545\" alt=\"\" srcset=\"https:\/\/thade-gerdes.de\/wp-content\/uploads\/2024\/08\/BG-L.png 111w, https:\/\/thade-gerdes.de\/wp-content\/uploads\/2024\/08\/BG-L-39x300.png 39w\" sizes=\"(max-width: 111px) 100vw, 111px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5e1948d elementor-absolute elementor-hidden-tablet elementor-hidden-mobile elementor-hidden-laptop elementor-hidden-tablet_extra elementor-widget elementor-widget-image\" data-id=\"5e1948d\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_position&quot;:&quot;absolute&quot;,&quot;motion_fx_motion_fx_scrolling&quot;:&quot;yes&quot;,&quot;motion_fx_translateY_effect&quot;:&quot;yes&quot;,&quot;motion_fx_translateY_speed&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:4,&quot;sizes&quot;:[]},&quot;motion_fx_translateY_affectedRange&quot;:{&quot;unit&quot;:&quot;%&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:{&quot;start&quot;:0,&quot;end&quot;:100}},&quot;motion_fx_devices&quot;:[&quot;widescreen&quot;,&quot;desktop&quot;,&quot;laptop&quot;,&quot;tablet_extra&quot;,&quot;tablet&quot;,&quot;mobile&quot;]}\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"111\" height=\"860\" src=\"https:\/\/thade-gerdes.de\/wp-content\/uploads\/2024\/08\/BG-R.png\" class=\"attachment-full size-full wp-image-4546\" alt=\"\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Few things worry builders more than the fear of unexpected costs.
