Spalling – Causes, Prevention, Repair

Spalling is caused by the freeze/thaw process which contracts/expands the concrete. This is especially a problem during the first couple of years often near the joints.

To prevent spalling, you need a hi-grade seal and cure which can allow the concrete to breath and but yet protect it – especially during that first critical year. V-SEAL is a HI-TECH deep penetrating sealer and cure that easily passes the ASTM one hundred day freeze/thaw test.

V-SEAL helps prevent spalling because it does not encapsulate the concrete like other sealers such as acrylics. In fact ,V-SEAL  has the necessary 2% VTR vapor transmission rate, which actually allows the concrete to “breathe”, preserving the tensile strength in spite of the contraction/expansion of the seasons. When  V-SEAL is applied it lets the concrete’s natural flexibility continue to operate so that it can inhale/exhale with the seasons.

When you use  V-SEAL, you can be sure you are using a deep penetrating HI-TECH formula that will go in and protect during those critical years and remain for many years to come. Often used on bridges and tunnels but suitable for residential and commercial.

If spalling has already occurred,V-SEAL can and should still be applied to keep the concrete in check and greatly assist from further damage.
Dusting is a problem and V-SEAL can really make a difference.
