We have fixed a leaking pipe penetration and stopped water ingress through a cold joint in the basement ceiling slab with targeted injections of hydrophilic polyurethane resin.
Generally speaking, a cold joint is the point of connection where old and new concrete meet. It commonly occurs during construction when one batch of concrete has begun to set before the next batch is added.
The old and the new concrete do not intermix and a so-called “cold joint” is formed as a result, creating a weakness in the concrete and a possible passageway for water intrusion.
Some defects in concrete structures are commonly caused by penetrations through the concrete made for service lines.
Pipe penetrations are sealed with a cement-based plug or a patch from the interior side of the building during the original construction. The plug does not seal the gaps throughout the whole wall or slab and the bond to the concrete usually fails over time. This pathway allows water to find its way into the gaps and seeps through the concrete around the pipe penetration.
When a hole for the service pipeline is drilled through the concrete, the coring process may cause damage to the concrete structure by creating cracks. The core hole can often provide a direct path for water to pass through the concrete structure.
Such passageways for water into buildings is what Waterstop Solutions specialises in sealing accurately and effectively.
