Project Type:

Multi-Family Apartment Building Walkway Renovation

Location:

Long Beach, CA

Overview:

This project addressed critical safety and structural issues in an elevated walkway deck of a multi-family apartment building. The walkway, constructed with a wood frame and plywood substrate, was covered with an original magnesite coating that had failed, leading to severe water intrusion into the living spaces below.

Challenges:

The major challenges included addressing the unsafe conditions due to the rotted plywood substrate and the failing or missing perimeter sheet metal flashings. The deck’s structural and waterproofing failures had rendered it unsafe for residents.

Solutions:

Demolition and Removal: The original magnesite coating and affected stucco at the base of the walls were removed to allow for comprehensive repairs.

Substrate and Flashing Replacement: Rotted plywood substrate was replaced, and new perimeter sheet metal flashing assemblies were installed and integrated with the stucco assembly to seal the deck from water intrusion.

Drainage Improvements: Corrections were made to the deck’s slope to ensure proper drainage and prevent future water accumulation.

Waterproofing Installation: A one-hour fire rated waterproof traffic coating was applied, featuring a durable and non-skid surface texture to enhance safety and longevity.

Efficient Project Execution: The renovation was completed with minimal downtime, allowing residents to quickly return to using the deck with limited inconvenience.

Outcome:

The walkway deck was successfully renovated, eliminating the water intrusion problem and restoring safety for the residents. The new waterproofing system provides a durable, non-skid surface that ensures the structure’s longevity and functionality.
