At Tonnelle Mall in New Jersey, what appeared to be a concrete repair project required much more extensive work beneath the surface.
Deteriorated concrete and aging steel components created the need for a larger restoration involving both the supporting structure and exterior commercial surfaces.
Our Solution
Diaz Contractor LLC approached the project in stages, beginning with the demolition and removal of damaged concrete to expose the underlying steel structure.
Our crew then worked on replacing deteriorated steel beams and installing metal decking as part of the reconstruction process.
With the structural components addressed, the next stage involved concrete installation and finishing to rebuild the affected commercial walkway areas.
The Results
This project went beyond improving the appearance of the property. It addressed deterioration beneath the existing surfaces while rebuilding essential sections of the commercial exterior.
From demolition and steel replacement to concrete reconstruction, the work demonstrates our ability to take on demanding commercial renovation projects.

Scope of Work:
Contractor: Diaz Contractor LLC

Concrete requires more than a smooth finish. Proper preparation, grading, drainage, and installation all affect how the finished surface performs.
We provide concrete work for residential and commercial properties, including:
From deteriorated concrete to new construction, we evaluate the existing conditions before determining the appropriate approach.

Outdoor spaces should look good, drain properly, and stand up to everyday use.
We design, install, repair, and improve exterior surfaces using materials appropriate for the property and project.
Outdoor Surface Services:
● Patios
● Brick Pavers
● Paver Walkways
● Stepping Stones
● Bluestone Surfaces
● Slate Surfaces
● Outdoor Living Areas
● Entryways
● Pathways
Proper base preparation and grading are especially important with paver and stone surfaces to help minimize movement and drainage problems over time.

Retaining walls aren’t simply decorative. They may need to manage soil, slopes, elevation changes, and water movement around a property.
We provide:
● Retaining Walls
● Rock Walls
● Block Retaining Walls
● Masonry Walls
● Landscape Walls
● Wall Repairs
● Wall Replacement
Drainage and site conditions are considered as part of the project because water can play a major role in retaining-wall failure.

It depends on the extent of the damage and what caused it. Minor cracking may be repairable, while significant settlement, deterioration, or movement can make replacement the better long-term option. The underlying cause should be identified before deciding how to proceed.
Cracks, loose bricks or stones, deteriorating mortar, leaning walls, and recurring water damage can indicate a masonry problem. Some issues can be repaired, while more extensive deterioration may require rebuilding. We evaluate the existing conditions before recommending the appropriate solution.
