Diaphragm wall and slurry wall<\/span><\/b><\/h1>\n<\/div><\/div><\/div>

Application:<\/b><\/h2>\n
    \n
  • quasi\u2011<\/span>watertight retaining walls for deep excavations<\/strong>, such as multi\u2011level underground car parks or deep road underpasses<\/span><\/li>\n
  • high resistance deep foundation elements (so-called barrettes)<\/strong><\/li>\n
  • cut-off walls to limit groundwater flow<\/strong> under leveesor contaminated site containment<\/span><\/li>\n<\/ul>\n

    Description:<\/b><\/h2>\n

    The principle of the technology is the excavation of a trench a <\/span>mechanical or hydraulic grab<\/strong>. During excavation, <\/span>the soil around the trench is supported by bentonite or polymer slurry<\/strong>. In case of <\/span>reinforced concrete diaphragm walls<\/strong>, once the trench is fully excavated, <\/span>the steel reinforcement cage is installed<\/strong>, followed by <\/span>concreting of the trench<\/strong>. For <\/span>self\u2011hardening slurry walls<\/strong>, the supporting slurry <\/span>hardens due to the added binder<\/strong>, forming <\/span>a low\u2011strength wall structure<\/strong>.<\/span><\/p>\n
