LEAK SEALING INJECTION WORKS IN A BELOW-GROUND CAR PARK
With hydrophilic polyurethane resin, we have fixed a leaky pipe penetration and stopped water ingress through a cold joint in the basement ceiling slab.
Generally speaking, a cold joint is a connection point where two pieces of concrete meet. During construction, this usually happens when one batch of concrete has begun to set before the next batch is added.
As a result, a so-called “cold joint” forms between the old and new concrete, creating a weak point in the concrete and a possible pathway for water to enter.
A common cause of concrete structure defects is penetrations through the concrete made for service lines.
During the original building construction, penetrations of pipes are sealed with cement-based plugs or patches. Plugs do not seal the gaps across the entire wall or slab, and the bond to the concrete usually breaks down over time. Water is able to seep through the concrete around the pipe penetration and find its way into the gaps.
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 Waterproofing Singapore specializes in sealing accurately and effectively.
Give us a call to discuss the best protective treatment application for your vertical and horizontal surfaces to help you choose the appropriate product and methods to protect them and how to best prepare the surface before installation for best performance.
If you have any issues with water ingress, rooftop leaks, leaking balcony, leaking basement, cracking concrete slabs, structural cracks, concrete deterioration, spalling concrete, concrete cancer, deteriorated joints, moisture, seepage, efflorescence, rising damp and/or high-flow active leaks in concrete structures, we would be happy to assist you. You are welcome to contact us with any questions that you may have.
