Leading Factors for Waterproofing Failures

4 Leading Factors Resulting in Waterproofing Failures

Identifying the reasons behind failures in waterproofing can prove to be a complex task, often leaving contractors in a state of uncertainty. Unfortunately, in their attempts to hide these failures, contractors often resort to vague excuses, which can be frustrating for all parties involved. However, by addressing and comprehending the main factors that contribute to these failures, we can effectively prevent costly repairs.

Outlined below are the four primary reasons behind waterproofing failures, along with practical solutions to overcome them:
1) Improper Material Selection:

One of the leading causes of waterproofing failures lies in the lack of appropriate selection criteria when choosing materials and systems. Without clear benchmarks, clients and architects can find themselves caught between over-specified or under-specified materials and designs.

To ensure success, it is crucial to accurately evaluate site conditions and select materials and designs that are suitable for the specific project. Seeking guidance from a waterproofing expert during the planning stage is highly recommended to make informed decisions.

2) Inadequate Workmanship:

Even with high-quality materials and systems, improper installation can undermine their effectiveness. To achieve optimal results, it is essential to assign experienced and well-trained teams to the task at hand.

Addressing workmanship failures can be achieved through the following measures:

  • Establishing a jointly approved work methodology that involves collaboration between the Quality Assurance team and the installer.
  • Strict adherence to manufacturers’ guidelines for installation, following a comprehensive checklist.
  • Implementing a risk assessment plan to ensure quality assurance throughout the process.
3) Project Deadlines:

Proper planning and consideration of construction schedules play a pivotal role in avoiding conflicts and failures in waterproofing projects. The Engineer in Charge (EIC) must prioritize maintaining the correct process and order of waterproofing installation while meeting construction targets. Neglecting this aspect not only leads to waterproofing failures but can also strain relationships between the installer and the client.

Allocating sufficient time for waterproofing works in a well-designed construction schedule is highly recommended.

4) Cost Constraints:

In an attempt to reduce costs and accommodate budget limitations, contracting teams may overlook the importance of essential components in the waterproofing system or resort to substandard materials. However, it is crucial to recognize that the long-term performance of a waterproofing system relies heavily on the use of high-quality products. Eliminating vital components will only result in higher repair costs in the future and can significantly tarnish the organization’s reputation.

It is worth considering a slightly higher initial cost to ensure the effectiveness and durability of the waterproofing system.

In conclusion, It is essential for all stakeholders, including contractors, clients, architects, and waterproofing experts, to collaborate closely and emphasize the use of high-quality materials and skilled workmanship. Prioritizing quality over short-term cost considerations is key to ensuring long-term satisfaction and performance.

 As wisely stated by Benjamin Franklin,

“The bitterness of poor quality remains long after the sweetness of low price is forgotten.”

We genuinely hope that this article has provided valuable insights into effectively addressing and mitigating waterproofing failures.
