Commercial Waterproofing in Miami & South Florida
Roof, deck, balcony, and below-grade waterproofing systems — installed by licensed commercial waterproofing contractors — that keep water out of condominium and commercial buildings across Miami-Dade, Broward, and Palm Beach County.
In Miami, Water Finds Every Weak Point
Wind-driven rain, salt air, relentless humidity, and one of the highest water tables in Florida push water at Miami buildings from every direction. It finds the weak points — flat roofs, plaza decks, balconies, window perimeters, expansion joints, and below-grade walls — and once it's in, the water damage compounds quietly: corroding reinforcement, rotting finishes, feeding mold growth, and turning a sealant repair into a structural one.
New Age Construction Group keeps water out. We design and install commercial waterproofing services for condominiums, HOAs, property managers, and commercial building owners across all three South Florida counties — with every system detailed correctly at every transition, because that's where waterproofing succeeds or fails.
7 Signs Your Building Has a Water Problem
Water intrusion almost always shows up far from where it's getting in. These are the signals our crews trace back to the source — and the earlier you catch them, the smaller the repair.
Water stains on ceilings or walls — discoloration inside almost always means water is entering somewhere on the envelope and traveling before it shows.
Efflorescence or mineral deposits — a white, chalky residue on concrete or masonry (the salts water leaves behind as it evaporates) shows moisture is moving through the material itself.
Cracked or failing sealant joints — gaps and splits in caulking around windows, joints, and transitions are a direct path for water infiltration.
Bubbling, peeling paint or coatings — blistered finishes mean moisture is trapped behind them and the surface is no longer protected.
Mold, mildew, or musty odors — persistent moisture inside walls or below decks creates health and habitability problems.
Pooling water on roofs or decks — standing water that doesn't drain stresses the membrane and finds every seam and penetration.
Rust stains or spalling near the envelope — spalling is concrete that cracks and flakes away as the steel inside corrodes; water reaching that steel is already causing the structural damage inspectors look for.

From the roof to the foundation — waterproofing solutions for every part of the building envelope where South Florida water gets in.
What Is Commercial Waterproofing?
Commercial waterproofing is the coordinated system of membranes, coatings, sealants, and drainage that keeps water out of a commercial building's roof, decks, balconies, walls, and foundation. It's not a single product — it's the whole building envelope working together, and it only works when every transition, joint, and penetration is detailed correctly. Done right, it protects the structure, the finishes, and the people inside.
In Miami, waterproofing is the difference between a sound building and a deteriorating one. Wind-driven rain, humidity, salt, and a high water table attack the envelope from every direction. Once water gets in, it corrodes reinforcement, rots finishes, breeds mold, and turns a small repair into a structural one.
Where Miami Buildings Leak
The most common intrusion points are flat and low-slope commercial roofs, plaza and amenity decks, balconies and terraces, window and door perimeters, expansion joints, and below-grade walls. Our waterproofing experts trace leaks to their actual entry point — which is rarely where the water shows up inside — and waterproof the source, not just the stain.
Because water travels along the structure before it surfaces, a proper diagnosis maps the whole path. Patching the interior symptom without finding the entry point is the single most common, and most expensive, waterproofing mistake we see on commercial properties.
Systems & Materials We Use
Depending on the application, our crews install fluid-applied and sheet membranes, elastomeric waterproof coatings, vehicular and pedestrian traffic coating systems, joint sealant systems, below-grade waterproofing and drainage, and vapor and moisture barriers — each detailed at the transitions, penetrations, and terminations where waterproofing systems usually fail.
We specify high-quality, manufacturer-warranted systems rated for South Florida's UV, heat, salt, and extreme weather conditions, and we install to the manufacturer's requirements — so the warranty holds, the workmanship is documented, and our waterproofing services are built to last.
Waterproofing & Milestone Inspections
Water intrusion is one of the most common findings in Florida's milestone and 40-year recertification inspections, because long-term leaks drive the concrete spalling and corrosion that inspectors flag. Restoring the building envelope is often a required part of closing out an inspection.
Getting ahead of it is also the best way to prevent the next inspection from finding structural issues. We waterproof to Florida Building Code and manufacturer standards and coordinate with your engineer of record, so the work protects the structure and stands up to review.
Water Damage Compounds — Quietly and Expensively
A leak is never just a stain. Here's what's at stake when water intrusion goes unaddressed.

The Commercial Waterproofing Contractors Miami Trusts
A Waterproofing Company Backed by a Structural GC
Most waterproofing contractors stop at the surface. New Age is a state-licensed general contractor (CGC#1531273) whose core work is concrete restoration and structural repair — so when a leak has already reached the structure, the same team diagnoses the water damage and repairs what it destroyed. Waterproofing, restoration services, and structural work under one roof, one contract, one accountable team.
OSHA-Certified Workforce
Every superintendent holds a 30-hour OSHA certification and every laborer completes the 10-hour safety course. Safety is a core operating standard — not a checkbox.
Deep South Florida Expertise
Years of experience with Miami-Dade's building codes, coastal climate, and recertification requirements that out-of-state crews simply don't have.
On-Time, On-Budget Delivery
We plan meticulously and communicate proactively, so your project stays on schedule and within the agreed budget.

Waterproofing That Protects Your Building — and Your Recertification
Water intrusion is one of the most common deficiencies flagged in Florida's milestone and 40-year recertification inspections, because years of leaking drive the concrete spalling and corrosion that inspectors cite. A sound building envelope is the first line of defense — and restoring it is often part of closing out an inspection.
New Age waterproofs to manufacturer and Florida Building Code standards, documents the systems and warranties, and coordinates with your engineer of record — so your waterproofing protects the structure and stands up to inspection.
