Waterproofing

Types of Waterproofing We Provide

Below-Grade Waterproofing

Foundation walls, basement areas, and below-grade structures require protection from groundwater and moisture vapor.

Applications include:

New construction foundation waterproofing
Elevator pit waterproofing
Tunnel and vault waterproofing
Blindside waterproofing applications
Remedial waterproofing for existing buildings with moisture problems

Plaza and Terrace Deck Waterproofing

Above-grade decks exposed to weather and pedestrian traffic require specialized waterproofing systems that accommodate movement, traffic loads, and various surface finishes.

Applications include:

Occupied roof deck systems
Plaza decks with pavers or landscaping
Balconies and terraces
Podium decks

Parking Structure Waterproofing

Parking decks experience intense traffic, chemical exposure from deicing salts, and constant moisture exposure. Waterproofing systems for these areas must withstand vehicle traffic while protecting the concrete structure.

Services include:

Traffic-bearing membrane installation
Expansion joint systems
Concrete surface preparation and repair
Coating systems for below-deck ceilings

Specialized Waterproofing

Green roof systems with drainage and root barrier layers
Fountain and water feature waterproofing
Loading dock seals and pit waterproofing
Through-wall flashing systems

Understanding Waterproofing Needs

Water Source and Pressure

Is moisture from groundwater under hydrostatic pressure, capillary action through concrete, or surface water drainage? The answer affects system selection.

Substrate Conditions

Water Source and Pressure

The condition and type of substrate (concrete, masonry, metal deck) influences what systems will perform well.

Accessibility

Water Source and Pressure

Building Movement

Can waterproofing be applied to the exterior (positive side) or must it be applied from interior spaces (negative side)? Positive-side waterproofing is generally more effective when possible.

Building Movement

Buildings experience thermal movement, structural deflection, and settling. Waterproofing systems must accommodate expected movement without failure.

How does waterproofing integrate with other building components? Transitions, terminations, and penetrations require careful detailing.
