The ground is dry, do I really need to waterproof my home?

When the ground appears bone dry, the need for below-ground waterproofing may not be immediately apparent. In this blog post, we'll delve into why it's essential to waterproof your property even in seemingly dry conditions.

Effective waterproofing design abides by a fundamental rule: the subterranean parts of a building will encounter water at some points during the life of the structure. Whether a full head height of water or a small trickling amount, water will follow the path of least resistance. This may occur through wall-floor joints, foundation cracks, pipe penetrations, or even small capillary pores within the concrete. Over time, this can affect your structure, internal fixtures, and belongings. Often, it can go unseen for a long time, causing damage to the property.

The water table is the level below the ground surface at which the soil and rock are saturated with water. It is a critical consideration in design, affecting the stability of foundations and the overall structural integrity of a building. Architects, builders, and homeowners need to be aware of the water table's location and fluctuations to make informed decisions about waterproofing, drainage, and other design elements impacting a structure's resilience against water-related challenges.

Water tables, though hidden from view, have dynamic responses to seasonal changes, precipitation, and geological influences. Despite the appearance of surface dryness, these water tables can undergo subtle or catastrophic fluctuations over time. Therefore, selecting products and determining their placement become critical aspects of this design.

Nature's unpredictability, especially in regions like New Zealand, can cause rapid changes in water tables. Unexpected weather events, like sudden downpours or storms, pose risks to property and belongings.

Below-ground waterproofing acts as a proactive defense against unforeseen changes in water that sits below ground. By creating a barrier between your property's foundation and the fluctuating water levels, you're mitigating the risk of water intrusion. This protects the structure, internal fixtures, fittings, and belongings, while also providing a safer air environment free from mildew and mould.

Investing in below-ground waterproofing is a strategic decision aimed at securing long-term stability. This proactive approach instills peace of mind, assuring property owners that their investment is fortified to withstand the unpredictable fluctuations in water tables, providing enduring stability and protection for years to come.
