Proper design and installation of below-grade waterproofing systems on foundation walls is essential to maintain a high-level of protection against water leakage over the long-term, particularly where basement areas are intended to be occupied. Site conditions can create unique challenges which include high groundwater levels, unusual soil conditions, and site/lot limitations, and are important factors in the selection and design of below-grade waterproofing systems. Water leakage problems through below-grade waterproofing systems are often difficult and expensive to correct, and the damage caused by water leakage can range from merely unsightly staining to significant problems with structural deterioration, among other things. In some instances, building structures are required to be located below the permanent groundwater level, resulting in a "tanked" structure. In other instances, the lower-level floor slabs-on-grade may be exposed to hydrostatic water pressure and may require below-slab waterproofing to protect the building interior from water leakage. These unique conditions require a thorough understanding of the site and soil conditions, the groundwater conditions, the structure, and the performance use and expectations related to the building interior. BC&E’s professional expertise has allowed for unique insight into problems with these types of features. In addition to permitting BC&E to develop unique solutions to addressing these problems, BC&E has the know-how to design these systems to reduce the risk of future problems in the design of these features in new buildings and additions. BC&E’s familiarity and knowledge of waterproofing systems and detailing during the design and construction stages facilitates their long-term success.

Horizontal waterproofing systems are utilized in exterior plazas and elevated decks. In many cases, these systems are constructed over finished, occupied spaces and require an exceptionally high level of protection against water leakage with a long service life. Exposure to harsh environmental conditions play a significant role in the selection of materials and assemblies. Performance and aesthetic design considerations for both intensive vehicular and pedestrian usage include the appropriate selection of pavement or decking materials, and correct integration of related architectural features. Some of these features include, but are not limited to, stairways, handrails, guardrails, sliding doors, planters, water features, pools, hot tubs, and exterior furnishings. Improper design and construction of these systems can cause significant damage and can be extremely disruptive and costly to repair. BC&E's professionals understand the importance of these features, and know that proper selection of materials, attention to details, and quality instillation of waterproofing and pavement systems is critical to the success of these systems. By evaluating hundreds of performance problems associated with plazas, we have developed strong skills and knowledge to correct leakage, drainage, or other problems associated with any type of plaza or deck.

BC&E’s expertise includes the evaluation of various types of fenestrations, including storefront and curtainwall systems, framed windows, and all types of doors. We regularly investigate common problems with fenestrations systems including water leakage, air infiltration, failed insulated glass units and excessive condensation and help develop solutions that fit the client’s needs. When assisting with a new build project, we focus on the design, detailing, and proper instillation methods for various systems to reduce the risk of future leakage problems.

BC&E's personnel have a wide range of experience in evaluating problems with various cladding systems and have designed repairs and renovation projects to address issues associated with the specific cladding system. Some issues we have evaluated include leakage, cracking or apparent movement, and excessive staining or efflorescence. We frequently help clients evaluate issues with concrete, stone and masonry facades; wood, fiber-cement, metal or vinyl siding; stucco, thin stone veneer, and EIFS; and various paints and coatings. We are also knowledgeable in providing direction where the wall system interfaces with other envelope systems, including windows, doors, below-grade waterproofing and roofing.
