Furthermore, some studies have ascertained that hydrodemolition\u00a0<strong>extends the life of the treated structure<\/strong>, with a repair duration of between 21 and 35 years compared to only 7-12 years obtainable from mechanical cutting.<\/p>\n<p>By avoiding vibrations and impacts, the reinforcement\u00a0<strong>does not loosen, microfractures do not arise and the integrity of the reinforced concrete substrate is protected<\/strong>. Pneumatic hammers and milling machines, however, can leave layers of dust and cause cracks up to 20 millimeters wide in the residual concrete, making the surface not ready to accept a new layer of concrete and compromising the bonding of the new concrete casting. With hydrodemolition, on the contrary, the surface of the armor remains intact and\u00a0<strong>rust and debris are perfectly removed<\/strong>.<\/p>\n<p>The increase in effectiveness also corresponds to a\u00a0<strong>reduction in manpower<\/strong>, effort and risks of accidents for operators. On the other hand, like the\u00a0<strong>speed and frequency of work<\/strong>, it also increases\u00a0<strong>safety<\/strong>: hydrodemolition in fact\u00a0<strong>eliminates the production of fine silicon dust<\/strong>\u00a0which is released with the mechanical cutting of concrete, masonry, rocks and granite; elements that cause silicosis, asthma, bronchopneumopathy and lung cancer. It is precisely the water from the pressurized jet that prevents the silicon from pulverizing and becoming dangerous volatile dust.<\/p>\n<p>Furthermore, hydrodemolition causes\u00a0<strong>less disturbance<\/strong>\u00a0in terms of noise and vibrations, to the advantage of both operators and people who live or pass near the construction site: an important socio-economic issue, especially for contractors.<\/p>\n<\/div><\/div><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-11 fusion_builder_column_1_1 1_1 fusion-flex-column\" style=\"--awb-bg-size:cover;--awb-width-large:100%;--awb-margin-top-large:0px;--awb-spacing-right-large:1.92%;--awb-margin-bottom-large:20px;--awb-spacing-left-large:1.92%;--awb-width-medium:100%;--awb-order-medium:0;--awb-spacing-right-medium:1.92%;--awb-spacing-left-medium:1.92%;--awb-width-small:100%;--awb-order-small:0;--awb-spacing-right-small:1.92%;--awb-spacing-left-small:1.92%;\"><div class=\"fusion-column-wrapper fusion-column-has-shadow fusion-flex-justify-content-flex-start fusion-content-layout-column\"><div class=\"fusion-separator fusion-full-width-sep\" style=\"align-self: center;margin-left: auto;margin-right: auto;margin-top:25px;margin-bottom:25px;width:100%;\"><\/div><\/div><\/div><\/div><\/div><div class=\"fusion-fullwidth fullwidth-box fusion-builder-row-5 fusion-flex-container nonhundred-percent-fullwidth non-hundred-percent-height-scrolling\" style=\"--awb-border-radius-top-left:0px;--awb-border-radius-top-right:0px;--awb-border-radius-bottom-right:0px;--awb-border-radius-bottom-left:0px;--awb-flex-wrap:wrap;\" ><div class=\"fusion-builder-row fusion-row fusion-flex-align-items-flex-start fusion-flex-content-wrap\" style=\"max-width:1341.6px;margin-left: calc(-4% \/ 2 );margin-right: calc(-4% \/ 2 );\"><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-12 fusion_builder_column_1_2 1_2 fusion-flex-column\" style=\"--awb-bg-size:cover;--awb-width-large:50%;--awb-margin-top-large:0px;--awb-spacing-right-large:3.84%;--awb-margin-bottom-large:0px;--awb-spacing-left-large:3.84%;--awb-width-medium:100%;--awb-spacing-right-medium:1.92%;--awb-spacing-left-medium:1.92%;--awb-width-small:100%;--awb-spacing-right-small:1.92%;--awb-spacing-left-small:1.92%;\"><div class=\"fusion-column-wrapper fusion-flex-justify-content-flex-start fusion-content-layout-column\"><div class=\"fusion-title title fusion-title-4 fusion-title-text fusion-title-size-two\"><div class=\"title-sep-container title-sep-container-left fusion-no-large-visibility fusion-no-medium-visibility fusion-no-small-visibility\"><div class=\"title-sep sep-double sep-solid\" style=\"border-color:#e0dede;\"><\/div><\/div><span class=\"awb-title-spacer fusion-no-large-visibility fusion-no-medium-visibility fusion-no-small-visibility\"><\/span><h2 class=\"fusion-title-heading title-heading-left fusion-responsive-typography-calculated\" style=\"margin:0;--fontSize:21;line-height:1.29;\"><strong>Versatility and selectivity<\/strong><\/h2><span class=\"awb-title-spacer\"><\/span><div class=\"title-sep-container title-sep-container-right\"><div class=\"title-sep sep-double sep-solid\" style=\"border-color:#e0dede;\"><\/div><\/div><\/div><div class=\"fusion-text fusion-text-6\"><p>Among the basic principles of hydrodemolition there is\u00a0<strong>selective removal<\/strong>: thanks to the precision of the pressurized water, only the quantity of concrete necessary for the renovation can be removed, without affecting the steel reinforcement or the intact concrete and managing to automatically eliminate local cracks.<\/p>\n<p><strong>By modulating the water pressure<\/strong>, therefore, we can obtain different results and\u00a0<strong>versatile applications<\/strong>\u00a0from the high pressure system.
