Problem:
Undersea road support structures required moving onto a submergible barge for placement into the sea.
To provide a smooth and level surface on the barge deck, ITW Chockfast was used. Due to the enormous
weight of the support structures, and the flexing of the barge from rolling seas, cracking occurred.
Surface cracking and hollow, uneven expansion joints caused extreme difficulty when rolling the support
structures onto the barge.
Solution:
Because of extremely high compressive strength and excellent flexibility, Flexane 94 Liquid was used to
fill expansion joints and repair cracked areas on the barge deck. Crack and expansion joint areas were
roughened and then chemically cleaned using Cleaner Blend 300. Expansion joints were filled or stuffed
with a polypropylene backer. This prevented Flexane 94 Liquid from migrating deep into the concrete.
FL20 Primer was applied and allowed to cure or dry for 15 minutes. Flexane 94 Liquid was poured into
the expansion joints and cracks. Flexane 94 Liquid provided a smooth, flexible, (350% elongation), level
surface allowing the structure to be moved easily and safely.
