WebDeep strip foundations may be necessary where soil with a suitable bearing capacity is deeper. Advantages Disadvantages A strap footing is more economical when the allowable soil pressure is relatively high and the distance between the columns is large. Prone to edge erosion. Suitable for poor or unequal soil bearing capacity Special measurements are needed when mat foundation is subjected to the concentrated load. Save my name, email, and website in this browser for the next time I comment. blogging. When pile foundation moves the load only through the skin resistance without any end bearing then the pile are called friction piles.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'constructionor_com-banner-1','ezslot_7',111,'0','0'])};__ez_fad_position('div-gpt-ad-constructionor_com-banner-1-0'); Under-reamed pile foundation is commonly used in black cotton soils that swell or shrink when exposed to water or in large quantities upon drying.
