It outlines construction requirements including materials, reinforcement placement, and protective measures like flexible closed-cell polyethylene foam pads. The content covers reinforcement details using #4 and #5 bars, clearance specifications, and trowel finish requirements, ensuring compliance with commercial grade concrete standards and structural integrity for piping systems under 72 inches in diameter. The document emphasizes that these designs should be implemented under the guidance of a registered professional engineer to adhere to accepted engineering principles and local specifications.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":30,"@type":76,"position":81},"https://docshare.wps.com/document/technology/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/concrete-encasement-cradle-and-cap-details-rd306/663773/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/concrete-encasement-cradle-and-cap-details-rd306/663773.png","ImageObject",300,407,{"name":92,"@type":93},"AfterMidnight","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-28",true,{"@type":102,"interactionType":103,"userInteractionCount":14},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What is the maximum pipe diameter applicable for these concrete encasement details?","Question",{"text":112,"@type":113},"These details are applicable to pipes up to 72 inches in diameter;
