rusting reinforcing steel in concrete Tag

Based on our inspector’s assessment, the spalling concrete along the slab edge is caused by water leaking through the floor/wall joint from the lawn and planter box area directly above the slab. During the inspection, our inspector noted that guttering was installed right underneath the slab...

Our client came to us to ask for advice on repairs of concrete cancer after their building inspector had identified exposed, rusting rebar with some cracking on the overhang beam on the side of the cantilevered pool. The concrete scan that the building inspector carried...

Several factors predetermine the risk of concrete cancer, including proximity to the coastline and a built-up environment; the degree of concrete cover to steel reinforcing; the presence of differential metals; the quality and density of coating systems; inadequate waterproofing; building defects cracking; joint and penetration...

Environmental stresses on concrete in coastal areas. Reinforced concrete structures degrade with time and exposure to the environment, particularly if that environment contains salts. Reduction of the concrete’s alkalinity either by carbonation or by the ingress of chlorides (salts) are the most common causes of concrete corrosion....

Calthemites is concrete, mortar or lime-derived secondary deposits consisting primarily of calcium carbonate that grow on or under man-made alkaline structures, such as concrete, and mimic the shapes and forms of cave speleothems, such as stalactites....
