Waterproofing

Commercial Waterproofing Contractor for South Florida Buildings

Every concrete and masonry restoration project we complete is only as durable as the waterproofing that protects it. JO Brothers Building Restoration is a full-service commercial waterproofing contractor serving condominiums, HOAs, hotels, and commercial property owners across Miami-Dade, Broward, and Palm Beach Counties. We design and install pedestrian and vehicular traffic coatings, balcony waterproofing, plaza deck systems, below-grade membranes, and elastomeric wall coatings using Sika, Tremco, Mapei, and Carlisle systems matched to each substrate and exposure.

Building Leak Repair and Leak Investigation

Finding the source of a building leak in a South Florida high-rise is a craft. We perform visual surveys, electronic leak detection, infrared scans, and isolated water testing to confirm the source before any tile, stucco, or membrane is removed. Then we deliver a single repair plan that addresses the root cause — not the symptom — and back it with a written workmanship warranty. From recurring balcony leaks above master bedrooms to plaza deck failures over occupied parking decks, our leak repair process saves owners from chasing the same problem year after year.

Balcony, Plaza Deck and Roof Waterproofing Systems

Balconies and plaza decks take the worst of the Florida climate — UV, salt spray, foot traffic, and standing water — and they are the most common source of envelope failures in coastal condominiums. We install fluid-applied traffic coatings, sheet membranes, and hybrid systems engineered for 15–20 year service life. On roofs we coordinate with re-roofing contractors and install transition flashings that integrate the wall, parapet, and roof into one watertight envelope. Combine waterproofing with our balcony structural repair and concrete restoration scopes for a complete, single-contract envelope program.
