Why You Shouldn't Skip Waterproofing?

Waterproofing, as the name suggests, is a crucial step in protecting a building from the damaging effects of moisture and water. One of the first stages of construction is conducting a soil survey, which helps determine the appropriate type of waterproofing necessary for the building.

Why is Waterproofing Necessary?

The underground parts of a building are constantly exposed to groundwater. Without proper foundation waterproofing, water infiltration into the basement can compromise the structural integrity of the entire building. Excess humidity negatively affects both building materials and the well-being of the occupants. Over time, it can lead to the formation of mold and mildew, which pose serious health risks.

Foundation waterproofing is essential, but it’s not the only area requiring protection. Other key building elements, such as walls, ceilings, roofs, balconies, terraces, and bathrooms, also need adequate waterproofing. Failing to secure these parts against water, temperature fluctuations, and humidity can lead to rapid deterioration and structural issues.

Types of Waterproofing

Waterproofing protects critical building components from water damage, preventing structural deterioration. Different waterproofing types are classified based on placement and function:

1. By Application Area:
   • Horizontal waterproofing – Applied beneath floor slabs or on top of foundations
   • Vertical waterproofing – Protects walls from water infiltration
2. By Function:
   • Waterproofing against water pressure (prevents water ingress from groundwater)
   • Damp-proofing (protects against non-pressurized water, such as moisture and rainwater)
3. By Protection Level:
   • Heavy-duty waterproofing – Used where water pressure is high
   • Light waterproofing – Suitable for low groundwater levels and permeable soils

How to Save on Waterproofing?

The best way to save on waterproofing is to invest in high-quality materials and professional workmanship from the start. Cutting corners on waterproofing during construction often leads to expensive repairs later.

Water infiltration is a progressive issue—once damage occurs, it is difficult to fix the underlying cause. Water migrates through structures, meaning that visible issues (such as peeling plaster or mold) may originate from a completely different location.

Unexpected Risks: Groundwater Level Changes

Even if your home is built on permeable soils, groundwater levels can change over time, putting your foundation at risk.

Imagine a neighborhood expansion:

• 10 years after building your home, new housing developments emerge in the area
• The groundwater level shifts, increasing hydrostatic pressure
• Standard damp-proofing fails, leading to water intrusion into the foundation
• In such cases, only high-performance waterproofing can provide adequate protection

Waterproofing: A Step You Can’t Skip

Skipping waterproofing can have severe financial and structural consequences.
Repairing a failed waterproofing system is expensive
Drying out a water-damaged building is difficult and time-consuming
Moisture accelerates material deterioration and encourages mold growth, posing serious health risks

The best approach is prevention. Investing in proper waterproofing during construction ensures that your building remains structurally sound for decades.
