Foot break in concrete wall

 The images that we show in this month's report correspond to a demolition carried out in South America, one of the areas of the World in which CRAS, the demolition cement manufactured by the Basque firm Kayati SL, offers solutions to the construction sector when a demolition with no explosives is needed. The challenge this time was, apparently, simple: removing the foot in the base of a concrete wall.

Things, however, are not so simple in this type of project. These demolitions have to be carried out in a quasi-surgical way, since the integrity of the rest of the wall is at stake, which can be damaged by the vibrations produced by a demolition using explosives or percussion machinery. Complications grow if, in addition, the work is carried out in an urban environment, or near roads.

The way in which CRAS executes demolition allows clean cuts, which end up breaking the part to be eliminated into fragments whose shape and size can be designed depending on how the perforations made to deposit the mortar prepared with the demolition cement. Kayati SL offers advice to its clients to define the parameters to be taken into account in these projects: diameter and depth of the perforations, their distribution, type of CRAS suitable to the conditions in which the demolition is carried out, especially the temperature ... With more than a quarter of a Century of experience in demolition projects, Kayati SL offers not only a leading product in quality, but also first-class technical support.

In the images, the first that can be seen is the distribution of the perforations, with the mortar already loaded. In this case, a mesh-shaped perforation has been made, parallel to the wall to be maintained, and with the first row of perforations flush with this wall.

After a few hours, the breaking process, generated by the hydration reaction begins to crack the concrete in parallel to the wall that has to be preserved. Shortly after is the moment when the concrete separates into "slices" ready for rubble.

The result is, once again, a clean, fast, efficient and safe work and a satisfied customer, this time ten thousand kilometers away from the CRAS manufacturing site.
