The steel beams in the basement ceiling are badly rusted and the floor is blown up.<!--more--><\/p>\n<hr \/>\n<h4><\/h4>\n<h2><span class=\"ez-toc-section\" id=\"Drying_basement_%E2%80%93_false_ceiling_must_be_renovated\"><\/span>Drying basement &#8211; false ceiling must be renovated<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In order to make the room usable in the future, the entire area had to be drained. I had already repaired the downpipes and uncovered the walls of the upper cellar on the outside. In addition, the entire <a href=\"https:\/\/commaik.de\/2014\/09\/trockenlegung-des-hauses-einbringen-von-drainage-und-wasserrohren\/\" target=\"_blank\" rel=\"noopener\">plinth area was drained with a drainage system.<\/a><\/p>\n<p>As the lower cellar extends to a depth of six meters below ground, it was not possible for me to expose the plinth in this area from the outside. The risk of the foundation walls collapsing was simply too great.<\/p>\n<p>So I had to work from the inside. I have described my experiences with the installation of a retrofitted horizontal barrier and the creation of a pump sump in the article <a href=\"https:\/\/commaik.de\/2021\/12\/keller-trockenlegen-1-jahr-spaeter-injektion-pumpensumpf\/\" target=\"_blank\" rel=\"noopener\">Draining the basement &#8211; 1 year later<\/a>.<\/p>\n<p>&nbsp;<\/p>\n<p>The basement ceiling with its rusted steel beams also required renovation. To do this, the old basement ceiling had to be removed and completely rebuilt. This all had to be done laboriously by hand, as there was no access for heavy equipment.<\/p>\n<p>The intermediate ceiling between the steel girders was filled with concrete screed. Reinforcement provided additional stability. After all, this cellar had also served as an air raid shelter during the war.<\/p>\n<p>The demolition was therefore very laborious.<\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<div id='gallery-1' class='gallery galleryid-21269 gallery-columns-3 gallery-size-thumbnail'><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/commaik.de\/upload\/2020\/10\/bestandsaufnahme-im-keller15.jpg'><picture><source srcset=\"https:\/\/commaik.de\/upload\/2020\/10\/bestandsaufnahme-im-keller15-253x253.webp 253w,https:\/\/commaik.de\/upload\/2020\/10\/bestandsaufnahme-im-keller15-300x300.webp 300w,https:\/\/commaik.de\/upload\/2020\/10\/bestandsaufnahme-im-keller15-75x75.webp 75w\" sizes=\"(max-width: 253px) 100vw, 253px\" type=\"image\/webp\"><img decoding=\"async\" width=\"253\" height=\"253\" src=\"https:\/\/commaik.de\/upload\/2020\/10\/bestandsaufnahme-im-keller15-253x253.jpg\" class=\"sp-no-webp attachment-thumbnail size-thumbnail sp-no-webp\" alt=\"Ein feuchter, vernachl\u00e4ssigter Keller mit abbl\u00e4tterndem Putz, freiliegenden Ziegelw\u00e4nden, zwei kleinen Fenstern mit Gitterst\u00e4ben und sichtbaren Schimmel- und Wassersch\u00e4den.

The constantly cool climate, which prevails in both summer and winter, is ideal for storing and preserving food.<\/p>\n<p>The depth of these cellars naturally ensures a constant temperature and high humidity. These conditions are ideal for keeping food such as potatoes, apples and pickled vegetables fresh for longer periods of time.<\/p>\n<p>However, when storing food, care must be taken to ensure that it is well ventilated to prevent mold growth. Food should be stored in containers or on shelves that allow air to circulate.<\/p>\n<p>In addition to the advantages, such as natural cooling and suitability for food storage, these cellars also have disadvantages. The high humidity can lead to moisture problems, which can affect not only the storage conditions but also the fabric of the building.<\/p>\n<p>The moisture can promote the formation of mold and damage wood and other materials.<\/p>\n<p>To reduce the disadvantages, it is important to take measures to control moisture. This includes good ventilation to keep the humidity low.<\/p>\n<p>In some cases, it may also be necessary to add insulation to the walls or install drainage or a dehumidifier to effectively manage moisture.<\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<h4><\/h4>\n<div class=\"atkp-container atkp-productbox-box  atkp-template-productbox\">\n                        <div class=\"atkp-box atkp-clearfix \"\n                 style=\"\">\n                <div class=\"atkp-predicateheadline atkp-predicate-highlight\">\n                    <span><\/span><\/div>\n                <div class=\"atkp-thumb\">\n                                            <img decoding=\"async\" class=\"atkp-image\" src=\"https:\/\/m.media-amazon.com\/images\/I\/51-XDD8qNNL._SL160_.jpg\" alt=\"Scheppach Druckluftspaten Aero&sup2;Spade Drucklufthammer f&uuml;r den Kompressor\" title=\"\">\n                                                                                <\/div>\n                <div class=\"atkp-content\">\n                    <a class=\"atkp-title\" href=\"https:\/\/www.amazon.de\/dp\/B07331Z2WC?tag=wwwcommaikde-21&amp;linkCode=ogi&amp;th=1&amp;psc=1\" rel=\"sponsored nofollow noopener\" target=\"_blank\" onclick=\"ga(&#039;send&#039;, &#039;event&#039;, &#039;Link (productbox, Amazon commaik-21)&#039;, &#039;click&#039;, &#039; (Renovate basement ceiling yourself &#8211; safely replace steel beams)&#039;);\" title=\"Jetzt kaufen bei Amazon\">Scheppach Druckluftspaten Aero&sup2;Spade Drucklufthammer f&uuml;r den Kompressor*<\/a>\n                    <div class=\"atkp-author\">by Scheppach<\/div>\n\n                    \n                    <div class=\"atkp-description\"><ul>\n<li>UNIVERSAL - Dieser Bauspaten bietet einen breiten, vielseitigen und universellen Einsatzbereich dank einer Vielzahl an verschiedenen Aufsteckwerkzeugen.<\/li>\n<li>ANGENEHM - Der Spaten verf\u00fcgt \u00fcber einen vibrationsged\u00e4mpften Gummihandgriff \u2013 dadurch werden die Arme bei der Nutzung des Druckluftspatens nicht m\u00fcde oder \u00fcberlastet.<\/li>\n<li>PRAKTISCH- Schneller und einfacher Werkzeugwechsel - mit dieser Eigenschaft punktet der Gartenspaten mit dem Druckluftantrieb, denn dadurch wird flexible und wechselnde Gartenarbeit m\u00f6glich.<\/li>\n<li>HOCHWERTIG - Ob Bauspaten oder Gartenspaten, der Aero\u00b2Spade ist dank dem geschmiedeten Spatenblatt ein zuverl\u00e4ssiger Helfer bei vielen verschiedenen Arbeiten.<\/li>\n<li>Empfehlung 24L Kompressoren: Kleinere Aushubarbeiten Empfehlung 50L Kompressoren: Mittlere Aushubarbeiten, Entfernen von Wurzelst\u00fccken Empfehlung 100L Kompressoren: Gr\u00f6\u00dfere Aushubarbeiten, Abbrucharbeiten<\/li>\n<li>LIEFERUMFANG -1x Scheppach Druckluftspaten Aero\u00b2Spade, 1x Spatenblatt, 1x Spitzmei\u00dfel, 1x Flachmei\u00dfel 25 mm, 1x Breitmei\u00dfel 60 mm, 1x Schaber<\/li>\n<\/ul>\n<\/div>\n                <\/div>\n                <div class=\"atkp-bottom\">\n                                            <span class=\"atkp-price atkp-listprice\"><\/span>\n                                                                <span class=\"atkp-price atkp-savedamount\"><\/span>\n                                                                <span class=\"atkp-price atkp-saleprice\">\n                            &nbsp;Price not available\n                                                            <span class=\"atkp_price atkp-baseprice\"><\/span>\n                                                    <\/span>\n                                        <a href=\"https:\/\/www.amazon.de\/dp\/B07331Z2WC?tag=wwwcommaikde-21&amp;linkCode=ogi&amp;th=1&amp;psc=1\" rel=\"sponsored nofollow noopener\" target=\"_blank\" onclick=\"ga(&#039;send&#039;, &#039;event&#039;, &#039;Link (productbox, Amazon commaik-21)&#039;, &#039;click&#039;, &#039; (Renovate basement ceiling yourself &#8211; safely replace steel beams)&#039;);\" title=\"Jetzt kaufen bei Amazon\" class=\"atkp-button\">Jetzt auf Amazon kaufen*<\/a>\n                                        <div class=\"atkp-container\"><\/div>\n                                            <span class=\"atkp-priceinfo\">Preis inkl.

The low location ensures stable temperatures and high humidity, ideal for preserving provisions.<\/p>\n<p><strong>2. what damage was caused by the damp in the lower cellar?<\/strong><br \/>\nFor years, water from leaking rainwater downpipes ran into the brickwork, causing rust on the steel beams of the basement ceiling and damage to the concrete floor. This moisture has significantly impaired the fabric of the building.<\/p>\n<p><strong>3. how was the cellar drained?<\/strong><br \/>\nTo drain the building, the downpipes were repaired, the walls in the upper area were exposed and a drainage system was installed in the plinth area. As it was not possible to expose the plinth in the lower cellar, it was drained from the inside.<\/p>\n<p><strong>4 Why did the basement ceiling have to be demolished by hand?<\/strong><br \/>\nAccess for heavy machinery was not possible due to the cellar&#8217;s location six meters below ground. The demolition therefore had to be carried out by hand using pneumatic tools and a sledgehammer.<\/p>\n<p><strong>5. how was the basement ceiling renovated?<\/strong><br \/>\nThe old ceiling was demolished, the damaged steel girders removed and the concrete ceiling replaced. New reinforcement was installed to increase stability.<\/p>\n<p><strong>6. what measures have been taken to prevent future moisture damage?<\/strong><br \/>\nIn addition to repairing the rainwater downpipes, drainage pipes were installed and a subsequent horizontal barrier was fitted to prevent the ingress of moisture.<\/p>\n<p><strong>7 Why was the cellar used as an air raid shelter?<\/strong><br \/>\nDuring the Second World War, many cellars, especially low-lying ones like this one, offered protection from air raids. The solid construction and stable basement ceiling made it a suitable shelter.<\/p>\n<p><strong>8. which tools were used to demolish the cellar ceiling?<\/strong><br \/>\nIn addition to a pneumatic chisel, which was used to loosen the concrete, a sledgehammer was also used to remove the loosened concrete parts.<\/p>\n<p><strong>9. how long did the demolition of the basement ceiling take?<\/strong><br \/>\nThe demolition of the approximately 15 square meter ceiling took a total of three days. The work was carried out painstakingly by hand.<\/p>\n<p><strong>10. how will the renovated cellar be used in the future?<\/strong><br \/>\nAfter the renovation, the cellar is to be used as a storage room, with long-term use as a hobby room or wine cellar also being considered.<\/p>\n<p>&nbsp;<\/p>\n<div id=\"comma-1996584917\" class=\"comma-nach-dem-inhalt comma-entity-placement\"><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3563316148321376\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-3563316148321376\" \ndata-ad-slot=\"6867259082\" \ndata-ad-format=\"auto\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({}); \n<\/script>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Our art nouveau villa was built in 1900 and has a full basement. However, there is another, previously unrenovated cellar beneath the basement. This was used in the past as a vegetable cellar and air raid shelter. The climate is therefore cool and humid. Over the years, leaking pipes on the outside have led to major water damage in this area. For years, rainwater from a roof area of more than 100 square meters ran directly into the masonry. This, of course, had a considerable impact on the building fabric. The steel beams in the basement ceiling are badly rusted and the floor is blown up.<\/p>\n","protected":false},"author":2,"featured_media":22586,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"cybocfi_hide_featured_image":"","footnotes":""},"categories":[3533,3532,3531,3530,3534],"tags":[4080,4073,4075,4071,4074,4081,3535,4082,4070,4076,4079,4078,4077,4072],"class_list":["post-21269","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-restoration-and-working-techniques","category-stories-from-the-construction","category-the-cellar-en","category-the-house","category-workshop-en","tag-basement-ceiling-steel-beam","tag-basement-floor-slab-renovation","tag-basement-renovation","tag-basement-renovation-old-building","tag-brick-floor-basement-renovation","tag-cellar-floor-renovation","tag-commaik-en-2","tag-concreting-cellar-floor-old-building","tag-damp-basement-renovation","tag-repair-basement-ceiling","tag-steel-basement","tag-steel-beam-installation-old-building","tag-steel-beam-old-building","tag-tamped-concrete-basement-renovation"],"acf":[],"_links":{"self":[{"href":"https:\/\/commaik.de\/en\/wp-json\/wp\/v2\/posts\/21269","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/commaik.de\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/commaik.de\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/commaik.de\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/commaik.de\/en\/wp-json\/wp\/v2\/comments?post=21269"}],"version-history":[{"count":0,"href":"https:\/\/commaik.de\/en\/wp-json\/wp\/v2\/posts\/21269\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/commaik.de\/en\/wp-json\/wp\/v2\/media\/22586"}],"wp:attachment":[{"href":"https:\/\/commaik.de\/en\/wp-json\/wp\/v2\/media?parent=21269"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/commaik.de\/en\/wp-json\/wp\/v2\/categories?post=21269"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/commaik.de\/en\/wp-json\/wp\/v2\/tags?post=21269"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
