In other words, the neighbouring building stands at the very edge of the excavation. Moreover, older buildings often have shallow footings, while the new basement goes deeper.<\/p>\n\n\n\n<ul class=\"wp-block-list fz-checks\">\n<li><strong>Space:<\/strong> the thicker the wall and the further it sits from the boundary, the smaller the basement.<\/li>\n\n\n\n<li><strong>Neighbour&#8217;s footing:<\/strong> once the dig goes below it, the soil under that footing loses support.<\/li>\n\n\n\n<li><strong>Anchors:<\/strong> the anchors that hold the wall can run under the neighbouring plot.<\/li>\n\n\n\n<li><strong>Rig:<\/strong> narrow streets and small plots restrict large rigs.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"space\">How close can the wall get to the boundary?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The space a pile wall takes from the basement has three parts: the pile diameter, the distance the rig can get from the neighbouring wall and the construction tolerance. So at the outline design stage we settle these three values together.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, the drilling axis of a piling rig cannot get closer than a certain distance to a wall, and that distance depends on the rig. A smaller pile diameter reduces this allowance. However, a thinner wall usually needs more anchors or props.<\/p>\n\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;6af2010aa6a7e&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"6af2010aa6a7e\" class=\"wp-block-image size-full fz-figure wp-lightbox-container\"><img decoding=\"async\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on--pointerdown=\"actions.preloadImage\" data-wp-on--pointerenter=\"actions.preloadImageWithDelay\" data-wp-on--pointerleave=\"actions.cancelPreload\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/fenzemin.com\/wp-content\/plugins\/fenzemin-core\/assets\/img\/fore-kazikli-iksa-turleri-en.svg?v=1\" alt=\"Bored pile wall types for shoring on tight urban plots: contiguous, tangent and secant piles, plan view\"\/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\tdata-wp-bind--aria-label=\"state.thisImage.triggerButtonAriaLabel\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.thisImage.buttonRight\"\n\t\t\tdata-wp-style--top=\"state.thisImage.buttonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><figcaption class=\"wp-element-caption\">Contiguous, tangent and secant piles.

That way, you do not need to leave a separate working gap between the two.<\/p>\n\n\n\n<div class=\"wp-block-group fz-svc-note is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Our advice:<\/strong> talk to the shoring contractor before you finalise the architectural design.

The table below summarises the options we meet most often on site.<\/p>\n\n\n\n<figure class=\"wp-block-table fz-table\"><table class=\"has-fixed-layout\"><thead><tr><th>System<\/th><th>When?<\/th><th>Watch out for<\/th><\/tr><\/thead><tbody><tr><td>Anchored bored pile wall<\/td><td>Deep excavation, if the rig can get on site<\/td><td>Anchors may run under the neighbouring plot<\/td><\/tr><tr><td>Secant bored piles<\/td><td>With groundwater<\/td><td>Needs more quantity<\/td><\/tr><tr><td>Propped wall<\/td><td>Narrow excavation, or no consent for anchors<\/td><td>Props get in the way of digging and building<\/td><\/tr><tr><td>Micropile wall<\/td><td>Shallow dig where a large rig cannot enter<\/td><td>Needs closer supports<\/td><\/tr><tr><td>Jet grouting<\/td><td>To protect the ground under the neighbour&#8217;s footing<\/td><td>Pressure and spoil return need constant monitoring<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The designer who prepares the shoring design makes the final call.

In that case, we build the wall as close to the footing as possible. Where needed, we also support the ground under the neighbour&#8217;s footing separately.<\/p>\n\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;6af2010aa7508&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"6af2010aa7508\" class=\"wp-block-image size-full fz-figure wp-lightbox-container\"><img decoding=\"async\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on--pointerdown=\"actions.preloadImage\" data-wp-on--pointerenter=\"actions.preloadImageWithDelay\" data-wp-on--pointerleave=\"actions.cancelPreload\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/fenzemin.com\/wp-content\/plugins\/fenzemin-core\/assets\/img\/temel-guclendirme-yontemleri-en.svg?v=1\" alt=\"Ways to support the ground under a neighbour\u2019s footing: micropiles, jet grout columns and grouting\"\/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\tdata-wp-bind--aria-label=\"state.thisImage.triggerButtonAriaLabel\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.thisImage.buttonRight\"\n\t\t\tdata-wp-style--top=\"state.thisImage.buttonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><figcaption class=\"wp-element-caption\">Three ways to support the ground under an existing footing, schematic drawing.<\/figcaption><\/figure>\n\n\n\n<ul class=\"wp-block-list fz-checks\">\n<li><strong>Jet grouting:<\/strong> forms columns under the neighbour&#8217;s footing and turns the soil into a bearing mass.<\/li>\n\n\n\n<li><strong>Micropiles:<\/strong> work with a small rig in a tight space and carry the load to a deeper layer.<\/li>\n\n\n\n<li><strong>Grouting:<\/strong> fills loose soil and voids.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Because this work touches the neighbour&#8217;s building, you need the neighbour&#8217;s knowledge and consent.

The real risk is that the spoil return coming up the bore stops.

The rig type and the neighbouring building decide the exact figure; therefore, we suggest settling it together at the outline design stage.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details fz-faq is-layout-flow wp-block-details-is-layout-flow\"><summary>Can we shore the excavation without touching the neighbouring building?<\/summary>\n<p class=\"wp-block-paragraph\">Often yes, because the wall stays on your own plot. However, if anchors run under the neighbouring plot or the neighbour&#8217;s footing needs support, you need the neighbour&#8217;s consent.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details fz-faq is-layout-flow wp-block-details-is-layout-flow\"><summary>Does jet grouting damage the building next door?<\/summary>\n<p class=\"wp-block-paragraph\">Done properly, it causes no vibration. The real risk is pressure building in the ground when the spoil return stops. For this reason, we monitor pressure and return constantly.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details fz-faq is-layout-flow wp-block-details-is-layout-flow\"><summary>What if a large piling rig cannot get on site?<\/summary>\n<p class=\"wp-block-paragraph\">In that case, options such as micropiles or jet grouting with smaller rigs come to the fore.
