Cold Joint Construction Sealants Can Migrate 30-40mm Onto the Adjacent Slab Surface
A Salisbury manufacturing facility floor had a cold joint between two concrete pours — a construction joint where the first slab section was poured and set before the adjacent section was poured against it. The contractor had applied a silicone-based bond breaker sealant to the face of the first pour before placing the second pour against it, to prevent the two sections bonding together.
In some applications, the silicone sealant is applied too heavily or without a backing rod and migrates slightly onto the top surface of the first pour along the joint edge. We didn't notice the migration strip during assessment — it was only 30-40mm wide and didn't look different from the surrounding concrete.
Primer fish-eyed in a precise 30-40mm strip running the full length of the cold joint on one side. Classic silicone contamination pattern, but narrower and more linear than typical silicone sealer or spray seal fish-eye. The bead-water test on the adjacent concrete was fine; the fish-eye strip itself bead-tested positive for silicone.
Salisbury is the heart of Adelaide's northern industrial and defence corridor — Main North Road, Salisbury Highway, and the manufacturing and logistics businesses adjacent to RAAF Edinburgh. DPTI approved. Cold joint edges are now specifically checked with the bead-water test on every Salisbury manufacturing floor with visible construction joints.

Cold joint sealants and bond breakers are applied to the vertical face of the first pour. Without a correctly positioned backing rod to control the sealant depth, or when applied by brush rather than gun, the sealant can slump or spread from the face onto the top surface of the first pour along the joint edge.

Typically 20-50mm from the joint edge onto the adjacent slab surface, depending on how the sealant was applied. The strip is sometimes visible as a very slight colour change or sheen in raking light, but often completely invisible until a bead-water test or primer application reveals it.

Yes — diamond grinding 1-2mm depth over the joint edge strip removes the silicone migration. The grinding produces a slightly different surface texture along the joint edge, but this is covered by the marking and not visible in normal conditions.
