Restoration waterproofing is always a unique undertaking as there are many unknowns. Identifying the source of the infiltration is the obvious first step and it is a challenging one. Properly diagnosing a leak may require numerous steps that include, but are not limited to, inspection, flood testing, dye testing, mock-ups, removal of finishes, and occasionally destructive test methods.

Setting Clear Goals

Before embarking on a restoration waterproofing project, it is important to set clear goals and expectations for all parties involved. Clearly, stopping water intrusion is normally the main goal. Various methodologies and products can be employed to achieve this goal. Each of those may have different costs, varying levels of site disruption, and varying timetables. These should all be discussed so the end customer can make a well-educated decision.

Understanding Water Migration

It is important to understand a few key concepts about water migration. Just because a leak only manifests in specific areas does not mean that there are no other locations allowing water ingress. Water seeks the path of least resistance, typically the low spots. As these low spots are remediated, the water may migrate to other failed areas. This can be further complicated if the repairs are conducted during a relatively dry time, as the leak migration may not manifest until the next rain event. Conducting waterproofing repairs during active leaking helps to identify leak migration issues. Flood testing before, during, and/or after the work also can help identify leak migration.

In summation, remedial waterproofing is often an explorative process and can require on-the-fly adjustments. Setting expectations, maintaining open communication with all involved parties, and attention to detail are essential to making the waterproofing process efficient and successful.
