Waterproofing and Sealants

Protecting Buildings from Water Intrusion

Water is one of the most destructive forces affecting buildings. Even minor leaks can lead to structural deterioration, corrosion, mold growth, interior damage, and costly repairs if not addressed properly.

RAS Engineering provides comprehensive waterproofing and sealant consulting services for condominiums, commercial buildings, parking garages, hotels, healthcare facilities, and mixed-use developments. Our engineers investigate water intrusion problems, identify root causes, develop repair specifications, and oversee construction to ensure long-term performance.

Whether your property is experiencing active leaks or you are planning a restoration project, our team delivers practical engineering solutions designed to extend service life and protect your investment.

Our Waterproofing Engineering Services

Leak Investigations

When water enters a building, the visible damage is often far from the actual point of entry.

Our engineers perform detailed investigations to determine:

• Sources of water intrusion

• Building envelope deficiencies

• Failed waterproofing systems

• Sealant deterioration

• Window and door leakage

• Roof-related moisture intrusion

• Balcony and terrace waterproofing failures

• Garage waterproofing deficiencies

We utilize a systematic forensic approach to identify the root cause before recommending repairs.

Sealant Evaluations

Sealants are a critical component of every building envelope. Over time, exposure to sunlight, moisture, movement, and weather can cause sealants to fail.

We evaluate:

• Expansion joints

• Control joints

• Window perimeter sealants

• Curtain wall sealants

• Masonry joints

• Precast concrete joints

• EIFS joints

• Roofing terminations

Our inspections identify:

• Cracking

• Separation

• Adhesion failures

• Cohesive failures

• Improper installation

• Aging and weathering

Waterproofing System Evaluations

Waterproofing systems require periodic assessment to ensure continued performance.

We inspect:

• Plaza deck waterproofing

• Balcony waterproofing

• Podium deck waterproofing

• Planter waterproofing

• Below-grade waterproofing

• Foundation waterproofing

• Traffic coatings

• Vehicular waterproofing systems

• Pedestrian waterproofing systems

Our evaluations help property owners plan repairs before significant damage occurs.

Building Envelope Assessments

Building envelope failures are among the most common causes of recurring leaks.

Our engineers evaluate:

• Exterior walls

• Windows

• Doors

• Roof systems

• Balconies

• Terraces

• Expansion joints

• Flashing systems

• Waterproofing membranes

We identify deficiencies affecting building performance and develop solutions tailored to your property.

Waterproofing Specifications

Successful repairs begin with proper engineering design.

RAS Engineering develops detailed repair specifications that establish:

• Scope of work

• Material requirements

• Installation procedures

• Surface preparation standards

• Quality control requirements

• Testing requirements

• Contractor qualifications

Well-written specifications reduce project risk, improve construction quality, and help ensure competitive contractor pricing.

Construction Administration and Inspection

Even the best repair design can fail without proper installation.

Our construction oversight services include:

Pre-Construction Meetings

We review:

• Contract documents

• Construction schedules

• Product submittals

• Shop drawings

• Installation procedures

Construction Inspections

Our engineers monitor:

• Surface preparation

• Waterproofing installation

• Sealant installation

• Membrane application

• Joint preparation

• Adhesion testing

• Quality control procedures

Final Acceptance Inspections

Before project closeout, we verify:

• Compliance with specifications

• Proper installation

• Completion of punch list items

• Overall system performance

Common Waterproofing Problems

Balcony Leaks

Balconies are continuously exposed to rain, sunlight, and thermal movement.

Common issues include:

• Failed waterproofing membranes

• Cracked coatings

• Improper drainage

• Deteriorated sealants

• Concrete cracking

Window Leaks

Water intrusion around windows can result from:

• Failed perimeter sealants

• Improper flashing

• Installation defects

• Building movement

• Aging components

Garage Water Intrusion

Parking structures often experience:

• Deck leaks

• Joint failures

• Traffic coating deterioration

• Concrete deterioration

• Reinforcing steel corrosion

Roof-to-Wall Transitions

Improper transitions between building systems are frequent sources of leakage.

We evaluate:

• Flashings

• Counterflashings

• Sealants

• Roof penetrations

• Mechanical equipment interfaces

Why Waterproofing Matters

Uncontrolled water intrusion can cause:

• Concrete deterioration

• Reinforcing steel corrosion

• Structural damage

• Mold growth

• Interior finish damage

• Reduced property value

• Increased maintenance costs

Proactive waterproofing maintenance helps avoid major restoration expenses and extends the life of building components.

Frequently Asked Questions

What is building waterproofing?

Building waterproofing consists of materials and systems designed to prevent water intrusion into structures, including roofs, balconies, walls, foundations, and parking garages.

How do engineers determine where a leak is coming from?

Engineers evaluate building components, review construction details, inspect potential entry points, and perform testing when necessary to identify the source of water intrusion.

How often should sealants be inspected?

Most building sealants should be evaluated every few years, particularly in coastal environments where UV exposure, moisture, and movement accelerate deterioration.

What are the signs of waterproofing failure?

Common signs include staining, leaks, mold, cracked sealants, spalling concrete, corrosion, and recurring moisture problems.

Can waterproofing failures cause structural damage?

Yes. Long-term water intrusion can corrode reinforcing steel, deteriorate concrete, damage structural elements, and lead to expensive repairs.

Do you provide waterproofing repair specifications?

Yes. RAS Engineering develops detailed engineering specifications and drawings for waterproofing and sealant repair projects.

Do you inspect waterproofing installations during construction?

Yes. We provide construction administration, quality assurance inspections, and installation monitoring to help ensure proper workmanship.

Can waterproofing issues affect condominium buildings?

Absolutely. Balconies, windows, roofs, garages, and exterior walls are common sources of water intrusion in condominium buildings.

Do you work on parking garage waterproofing projects?

Yes. We evaluate, specify, and inspect waterproofing systems for parking garages, podium decks, and traffic-bearing surfaces.

Do you provide services throughout Florida?

Yes. RAS Engineering provides waterproofing and sealant consulting services throughout South Florida and surrounding regions.
