Commercial Waterproofing Services
Protecting structures from water intrusion through proven systems: hot‑rubber, foundation waterproofing, traffic coatings, below‑grade membranes, and joint sealants.
Water Intrusion Problems We Solve
Commercial buildings fail when water finds its way into concrete, foundations, elevated slabs, or structural joints.
Our job is to identify the source, document the condition, and apply the correct waterproofing system for long‑term protection.
Common issues we address:
- Foundation leaks and below‑grade seepage
- Concrete cracking allowing moisture migration
- Ponding on decks, walkways, or podium slabs
- Failing sealant joints on commercial buildings
- Deteriorated waterproofing membranes
- Water intrusion around penetrations and transitions
- Traffic deck wear from vehicles and foot traffic
These failures only grow more expensive with time — especially when they reach structural materials.
BEST provides documented findings before any system is recommended.
Foundation Waterproofing (Below‑Grade)
Foundation walls and below‑grade surfaces require systems that can handle hydrostatic pressure, soil contact, and long‑term moisture exposure.
Systems we install:
- Cold‑applied waterproofing membranes
Flexible, durable systems ideal for complex surfaces and tight access. - Sheet-applied membranes
Consistent thickness and reliable adhesion for foundation walls. - Bentonite systems
Self‑sealing performance under earth pressure.
Every system is installed with proper detailing around penetrations, footings, edges, and transitions — the areas where most waterproofing failures begin.
Hot‑Applied Waterproofing (Hot Rubber)
Hot‑rubber waterproofing is one of the most durable, seamless systems available for commercial structures, podium slabs, and inverted roof assemblies.
Ideal for:
- Podium decks / plaza decks
- Below‑grade walls
- Elevated slabs
- Landscaped rooftop areas
Advantages:
- Fully bonded, seamless monolithic membrane
- Excellent crack‑bridging
- High puncture resistance
- Compatible with overburden (pavers, soil, insulation systems)
Traffic Coatings (Pedestrian & Vehicular)
We provide commercial traffic coating systems that protect concrete from abrasion, water intrusion, chemicals, salts, and continuous use.
Applications:
- Parking garages
- Walkways & stair systems
- Balconies & breezeways
- Podium slabs
- Rooftop amenity areas
System benefits:
- Slip resistance for pedestrians
- UV‑stable coatings for long‑term performance
- Chemical resistance for parking decks
- Seamless waterproofing protection
Joint Sealants & Expansion Joint Systems
Commercial structures fail most often at transitions and joints. We install and replace sealants that prevent moisture intrusion where materials move, flex, and meet.
We seal and waterproof:
- Expansion joints
- Control joints
- Parapet transitions
- Window and door perimeters
- Concrete slab joints
- Pipe and mechanical penetrations
Correct sealant application is a critical part of long‑term commercial waterproofing — not an afterthought.
How We Diagnose Waterproofing Failures
1. Site Inspection
We evaluate water paths, membrane condition, drainage, penetrations, and existing detailing.
2. Photo‑Documented Findings
You receive a clear report showing where water is entering and why — with no vague explanations.
3. Solution Path
We recommend the correct repair, restoration, or replacement method based on system type and structural needs.
