SealTech infrastructure products​

By sealing off concrete poles, bridge pillars and other concrete construction, SealTech can prevent alkali-silica reaction. A phenomenon that causes concrete exposed to moisture to crack due to the reaction between aggregates containing certain forms of silica and with alkali hydroxide in concrete, or more commonly known as concrete cancer. 

The reaction causes the expansion of the altered aggregate by the formation of a soluble and viscous gel of sodium silicate. This hygroscopic gel swells and increases in volume when absorbing water: it exerts an expansive pressure inside the siliceous aggregate, causing spalling and loss of strength of the concrete, finally leading to its failure. 

Alkali-Silica reaction can lead to serious cracking in concrete, resulting in critical structural problems that can even force the demolition of a particular structure.
