– “Band-aid” fixes like drip trays/drip pans can accelerate and hide symptoms of rusting reinforcing steel embedded in the concrete slab.

 

The inventive solution to a leaking pipe penetration in the video above shows that while the water is re-directed, the issue has not been rectified. Moisture is still allowed to travel through the pathway of the pipe penetration. Drip trays can hide visual signs of concrete cancer, like delamination, spalling, calcium deposits (e.g. calthemite stalactites), efflorescence (salt deposits), rust stains from embedded reinforcing steel, exposed rebar. Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration in concrete.

This is why installing drip trays/drip pans are a short-term solution. They re-direct water leaks in concrete slab ceilings, but they do not fix the root cause. To protect against asset deterioration, to ensure a longer asset lifetime and avoid an increased long-term capital cost, we recommend leak sealing injections that will stop water from entering and travelling through the pathway of the core hole in the concert slab. Concrete repairs are also advised as part of the solution if required.

 

 

 

Why is leaking pipe penetrations a common problem?

Water leaks around pipe penetrations/core holes forย gas, water, sewer and electrical lines, is a prevalent problem. A common reason is that they are sealed with a cement-based water plug or a patch from the interior side of the building during original construction. The bond to the concrete fails over time, allowing a pathway for water to leak around the pipe penetration. The plug does not seal the gaps throughout the whole wall or slab and eventually, water finds its way into the gaps and leaks through the wall or slab around the pipe. Another common reason is that when a hole for the pipe is drilled through the concrete, the coring process through the concrete wall or slab can cause damage to the concrete structure by creating cracks or breaking chips out of concrete. This can provide a direct path for water to pass through the concrete.

Any water that finds a seepage path through cracks and air voids present in concrete will readily carry minerals such as calcium hydroxide and calcium ion to the underside of the structure. When the leachate solution makes contact with the carbon dioxide in the air, it causes a chemical reaction, which deposits calcium carbonate on the outside of the concrete structure.

Other trace elements such as iron from rusting reinforcing steel may be transported and deposited by the leachate at the same time as the calcium carbonate. This may give the calthemites an orange or red tint. The sight of calthemite is a visual sign that calcium is being leached from the concrete structure and may indicate that the concrete is gradually degrading. In steel-reinforced concrete, the presence of water, oxygen and chlorides breaks down the alkaline protection provided by the concrete to the steel, and this can lead to the development of concrete cancer if left untreated.

 

A correct and cost-effective solution

 

Waterstop Solutions leak sealing injection and remedial waterproofing specialists frequently carry out leak sealing injections that will stop water from entering and travelling through the pathway of the core hole in the concrete slab.

By injecting hydrophilic polyurethane resin that chases the water into the fine cracks and pores of the concrete, the technician achieves a 3-dimensional waterproof and flexible seal. ๐‘ป๐’‰๐’† ๐’ƒ๐’†๐’๐’†๐’‡๐’Š๐’• ๐’๐’‡ ๐’•๐’‰๐’Š๐’” ๐’Š๐’๐’‹๐’†๐’„๐’•๐’Š๐’๐’ ๐’”๐’š๐’”๐’•๐’†๐’Ž is that it fault finds and treats unidentified at-risk adjacent areas, offers additional protection to any reinforcing steel in the path of the crack and slows the corrosion to any possible compromised reinforcing steel or yet to be.
Once the leak sealing injections are completed, the injection ports are removed, and the holes and cracks are plugged with rapid-setting repair mortar.
