Below-Grade Waterproofing Systems

Below-grade waterproofing is a highly specialized component of a structure, which is necessary to protect your valuable building assets for decades to come. Waterproofing can best be described as the treatment of a below-grade surface or structure in order to prevent water infiltration under hydrostatic pressure. By properly waterproofing a structure, you not only protect the space and its contents from costly water damage, but you also preserve the structure itself. After all, if a building isn’t properly waterproofed, even a small leak could cause the structure to erode or degrade over time, damaging other parts of the facility.

What Distinguishes Inspec from Other Firms?

Essential to waterproofing design performance is having a thorough understand of the existing building conditions, the exact cause of the problem, and knowing which design solutions work long term and which do not. Inspec meets these criteria in the following ways:

  • We have a strict protocol of verifying existing conditions and water infiltration issues with on-site inspection openings, rather than relying solely on the existing drawings.
  • With a combined history of over 45 years’ experience of investigating waterproofing failures, we have a unique knowledge that we bring to bear when designing waterproofing solutions. We know what works and what does not.
  • Unlike many above-grade building components such as masonry and roofing, below-grade waterproofing must last the life of the building without maintenance or replacement. This is due to the disproportionately high cost of re-accessing and replacing below-grade waterproofing. This is why Inspec designs its waterproofing systems to last the life of the building.
