The Primary Reasons For Basement Waterproofing Failures

When disaster strikes – Predicting and preventing basement waterproofing failures before they ruin your day

Failures in waterproofing are the most common insurance claims in residential and commercial properties. The costs associated with waterproofing failures are substantial, and the extent of damage poses considerable risks. What are the primary reasons behind waterproofing failures, and how can these issues be addressed? Keep reading to learn the causes and solutions of basement waterproofing failures.

Use Of Low-Grade Materials

  • The choice of materials plays a substantial role in the effectiveness of waterproofing systems. Using inadequate or substandard materials is a significant contributor to failures in waterproofing. Whether it’s the wrong membrane type, sealant, or adhesive, opting for poor-quality materials can lead to compromised waterproofing.

In many instances, budget-friendly measures may result in the selection of cheaper materials, compromising long-term durability and effectiveness. This decision can result in premature deterioration, reduced resistance to environmental factors, and an overall decrease in the system’s ability to withstand water penetration. To prevent failures, it is crucial to thoroughly assess the project’s needs and invest in high-quality, industry-approved materials that align with the specific waterproofing requirements.

Improper Drainage

  • Inadequate or improper drainage is a key factor contributing to waterproofing failures. Poor drainage can accumulate water, increasing hydrostatic pressure on the waterproofing system. This pressure can compromise the system’s integrity, leading to leaks, seepage, and other water-related issues. Insufficient slope or pitch in roofs, balconies, and decks can block water runoff, causing water to pool and accumulate.

Clogged or poorly designed drainage systems can exacerbate the problem, allowing water to penetrate the foundation. Ensuring proper slope and pitch design is essential. Moreover, effective drainage systems such as gutters, downspouts, and drains can help address drainage-related issues. Regular maintenance and clearing of drainage pathways are crucial in preventing water from pooling and exerting undue pressure on the foundation.

Adhesive Failure

  • The third most prevalent issue in waterproofing is adhesive failure induced by lingering moisture. This can lead to the detachment of the waterproofing material. Building standards mandate substrate dryness when installing waterproof covering materials over concrete and mortar screeds. Builders or waterproofing contractors must assess surface dryness before applying a waterproofing coating.

Waterproofing contractors should select a membrane suitable for the specific surface they are working on. A strong waterproofing system will protect your basement against environmental factors and potential building movements.

Opt for Professional Waterproofing Services

  • Working with a certified and licensed waterproofing professional is essential for avoiding potential issues or failures in your property’s waterproofing system. Attempting DIY solutions may exacerbate the problem, making it crucial to seek the expertise of a trained basement waterproofing expert. Certified professionals are experienced in industry standards and have the necessary skills to inspect your site thoroughly.

Waterproofing failures can significantly impact a property’s safety and value. A competent contractor ensures site preparation and the correct application of waterproofing materials per the manufacturer’s guidelines, ensuring the durability of the coating.
