Commercial Waterproofing in Delray Beach

The Historic Old Town Commercial District contains buildings from 1912 to 1949, most using lime-based mortar and early masonry substrates that are vapor-permeable by design. Applying a film-forming elastomeric coating to these buildings traps moisture vapor within the wall, causing internal deterioration that can be more damaging than the original water intrusion source. Breathable penetrating sealers and Jahn-compatible substrate treatments are the appropriate system for these facades. Our Certified Jahn Applicator status means we can specify and apply waterproofing treatments that integrate with the original substrate composition, protecting the building while preserving its historic character.

Zone AE is Delray Beach's FEMA Special Flood Hazard Area designation along the Intracoastal Waterway corridor. In Zone AE, the water table adjacent to unprotected below-grade commercial foundations responds to tidal cycles in the Intracoastal rather than only to storm events. This means below-grade commercial foundations in these zones experience hydrostatic pressure continuously. Correctly specified below-grade waterproofing requires membrane systems, drainage board, and where access is constrained, crystalline waterproofing, rather than surface-only treatments.

Under Florida SB 4-D, condominium and cooperative buildings three stories or more must complete a milestone inspection by 25 years for buildings within 3 miles of the coastline, subject to the local enforcement agency's determination, and by 30 years otherwise, with subsequent inspections every 10 years. The Delray Beach Building Division issues the inspection notice and enforces a 180-day remediation deadline from the notice date. Waterproofing deficiencies including failed expansion joints, deteriorated building envelopes, and parking structure coating failures are among the most common findings. Proactive waterproofing before an inspection notice is received is consistently less costly and less time-constrained than responding to a documented finding.

We develop a phasing plan with the building owner and property manager before mobilization. Most above-grade facade and envelope work can be staged during off-hours or across sections to maintain business access throughout. For plaza deck and parking structure scopes, level-by-level sequencing maintains access during the program. We confirm the phasing approach and any appearance review requirements with building management before work begins, and the phasing plan is included in the written scope before any mobilization.

Call us at (561) 475-0775 or request an on-site assessment through pennacchiindustries.com. For milestone inspection compliance scopes, send us the Phase 1 or Phase 2 deficiency report before the site visit. For Historic Old Town Commercial District properties, let us know the building age and facade type in advance so we can prepare for substrate identification as part of the assessment. All proposals are written and fixed-price. Anthony Pennacchi & Sons, 2875 South Ocean Blvd., Suite 200-18, Palm Beach, FL, (561) 475-0775.
