How cracks and water decreases the concrete’s lifetime

According to the American Concrete Institute (ACI), the indices that indicate that the concrete’s durability is being compromised are increasing. The great growth of the appearance of pathological manifestations is attributed to the problems of waterproofing layer of the concrete structures.storyboard degradação 11A concrete structure subjected to a water infiltration will expand the crack with greater speed, making the process more and more accelerated, opening the way for the faster entry of aggressive agents of the environment into the structure, facilitating the harmful action of the carbon dioxide and chlorides on the steel structure.

“It is essential to eliminate infiltration points when they are identified in order to avoid the evolution of the problem to other regions and stop the deterioration, that compromise the structure”

Why use injection to eliminate infiltrations?

All infiltration begins in the “tension points” of the concrete structure. “Tension points” are localized structural efforts due to the retraction and thermal expansion of the different materials, structural movements and building settlement, which generate the cracks and constantly damage the waterproofing layer.

In addition, concrete and steel are two materials with different properties that work together, and it is impossible to predict their behavior when exposed to the inclement weather. In this way, it is natural for cracks and microcracks to appear on the concrete, serving as an entry point for aggressive agents such as carbon dioxide and chlorides, which reduce the durability of the structure.Quadrinho causa deterioração SWSo, redoing the waterproofing layer in addition to having a much higher cost, does not solve the cause of the problem, resulting in a short time, new damages in the same regions, since the waterproofing layer does not support structural movements. In addition, the sealing of cracks and microcracks in concrete is essential to stop the penetration of carbon dioxide and chlorides that are attacking the structure

The ultimate solution for these cases is the injection of the Elastic Polyvinyl Liquid from SealWizard, that will seal all  the cracks and the infiltration points of the waterproofing layer, absorbing the movements of the structure, because of it’s permanent flexibility.

How VedaJato Injection System Works

The VedaJato® injection system is mainly used to seal the concrete cracks and repair the waterproofing layer made of membranes or resins in new or older structures.storyboard injeção 11 SWThe VedaJato® Injection technology is a special system for treatment of cracks and fissures in concrete or similar substrates. What was considered a difficult problem and often treated with palliative methods, our injection system became a definitive solution. The VedaJato® unique system combines a special Elastic Polyvinyl Liquid, a High Pressure Electronic Pump (280Bar) and application accessories. Our unique equipment is all automated to ensure that the injection has a standardized and homogeneous filling in the expansion joints, microfissures and the capillary structure.proteção estrutura SWPreserving the waterproofing layer is essential to protect the structures against deterioration caused by infiltration.

Ecologic systemecologico

Construction accounts for 50% of all solid waste generated in major cities. VedaJato® technology avoids the generation of debris, since you do not have to break anything to eliminate infiltration. It also generates savings in water consumption since it is not necessary to empty swimming pools, water tanks and reservoirs to eliminate infiltrations.
