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.
