Waterproofing

Horizontal waterproofing systems are utilized in exterior plazas, rooftop terraces, and balconies. In many cases, these systems are installed over finished, occupied spaces and require an exceptionally high level of protection against water leakage.

The design of horizontal waterproofing systems is uniquely challenging due to the wide variety of conditions to which these systems will encounter. Environmental conditions play a significant role in the selection of materials and assemblies.

In addition to the waterproofing systems, design considerations include final pavement or decking materials and related architectural features, such as stairways, handrails and guardrails, planters, water features, pools, hot tubs, and exterior furnishings.

Lack of attention to details and/or poor quality installation of waterproofing systems can cause significant damage and can be extremely disruptive and costly to repair.

The design of below-grade waterproofing systems is equally important to maintain a high-level of protection against water leakage, particularly where basement areas are intended to be occupied. Site conditions including groundwater levels, soil conditions, site/lot limitations, and construction methodologies are important factors in the selection and design of below-grade waterproofing systems.

Water leakage problems through below-grade waterproofing systems are difficult and expensive to correct. The damage caused by water leakage can range from merely unsightly to creating significant problems with structural deterioration, among other things.
