spikefast is a patented dual component, non-foam polyurethane product which is applied with a wvco metering and dispensing system that helps eliminate problems inherent in other dual component spike hole filler products. spikefast is proven to anchor spikes better and longer than other traditional plugging materials. it can be applied in extreme weather conditions, including heavy rain, freezing temperatures and high humidity. it is easy to adz and ready to re-spike within 10 minutes. and it bonds so tightly to the spike hole surface that it will not dislodge during the adzing process. unaffected by water, spikefast completely displaces standing water in spike holes without excess foaming and it deeply penetrates cracks, voids and crevices in the tie to reduce moisture infiltration and tie rot.
