What Is Water Ingress?

Water ingress, the unwanted infiltration of moisture into a building, is a silent but destructive force. It’s a term that can send shivers down your spine if you’re a property owner or manager.

Left unchecked, it can lead to costly repairs, compromise the structural integrity of your building and even create potential health hazards. Understanding what water ingress means and implementing preventative measures can safeguard the longevity and value of your property.

The dangers of water ingress

Water ingress often works behind the scenes, causing damage long before you notice any visible signs. As water seeps into the concrete, it can cause the steel reinforcement to corrode, a condition commonly known as “concrete cancer”. This corrosion weakens the integrity of the building, potentially leading to cracks, instability and even severe collapse.

The consequences of water ingress don’t stop at structural damage as moisture creates the perfect breeding ground for mould and mildew. Exposure to mould spores can trigger various health problems, especially for those with respiratory sensitivities like allergies and asthma. Additionally, a building with a history of water ingress will likely suffer a decrease in property value, making it a less attractive investment.

Water ingress meaning and probable causes

Water ingress refers to the penetration of water into a building’s structure or interior spaces where it shouldn’t be. This intrusion can occur through various pathways and result in significant damage if not addressed promptly. Some of the most common causes of this phenomenon include:

  • Structural defects — Cracks in walls, foundations or around windows and doors offer easy entry points for water.
  • Faulty or missing waterproofing — Inadequate or deteriorated waterproofing membranes in basements, balconies and roofs allow water to seep through.
  • Poor drainage — Improperly designed or clogged drainage systems can cause water to pool around the building, increasing the risk of ingress.
  • Damaged roof or plumbing systems — Leaks in roofs, gutters or pipes can lead to water intrusion within walls or ceilings.
  • Extreme weather conditions — Prolonged heavy rain, flooding or strong winds can overwhelm a building’s defences and force water into vulnerable areas.

Signs to look for

Water ingress doesn’t always announce itself with a dramatic leak. Be vigilant for subtle clues — both visible and hidden — as they could be early warning signs of a developing problem. For starters, look for damp patches on walls or ceilings, the telltale presence of mould growth, peeling or bubbling paint and white, powdery deposits (efflorescence) on surfaces. These visible signs indicate moisture intrusion.

Furthermore, don’t dismiss musty odours, warped wood or unexplained stains as harmless either — they can all point to hidden water issues within your building’s structure. Taking these signs seriously and investigating them promptly could save you from costly repairs down the line.

Water ingress solutions

Addressing water ingress requires a professional assessment to determine the root cause and the best remedy. Standard repair methods include crack injection, waterproof membranes and drainage improvements.

It goes without saying that prevention is key, so regular maintenance is something that must never be neglected. But if you do notice signs of water ingress, don’t let the situation worsen — timely action can save you significant costs in the future.
