When an anchor is installed into concrete, there is an area surrounding the anchor called a cone of influence in which the anchor is affecting and it is affected by. When two anchors are spaced too closely to one another and/or too closely to an edge, the anchor’s cone of influence reduces or becomes interfered …

INTRODUCTION The main purpose foundations serve is to distribute and resist the forces or loads experienced by the host structure due to wind, rain, snow, seismic, & other load conditions. When it comes to building components such as generators, signs, and fences the code leaves a gray area for foundation design. This happens because most …
Here’s a description and illustrations we’ve created for footing types we frequently reference in our work for sunrooms, pergolas, carports, screen rooms, signs, and similar at-grade building component structures. Photos of each appear below. An isolated footing is used to support a single post. Isolated footings are independent footings which are provided for each …
Footings Move When Soil Freezes. Let’s Explain. Building codes describe the design requirements of shallow foundations in regions where soil is subjected to seasonal ground freezing. Codes require that footings be protected from frost to prevent a phenomenon known as heave. Frost heave occurs when water penetrates the ground soil and subsequently freezes. When water …
