The Impact of Sea Level Rise on Concrete Structures in North Miami

Understanding Rising Sea Levels in North Miami

North Miami and much of South Florida are currently being impacted by increasing rates of sea level rise. Recent studies reveal:

• Sea levels in South Florida are rising at six times the global average.
• The 2040 projections show a rise of approximately 10 to 17 inches.
• Flooding and saltwater intrusion into freshwater aquifers are already apparent.
• These changes will have long-lasting impacts upon the built environment and especially upon structures constructed using concrete.

Impact of Sea Level Rise on Concrete

Saltwater Intrusion

• Chlorides in seawater will erode and corrode steel reinforcement within concrete.
• Structural integrity will be diminished and potentially compromised.

Hydrostatic Pressure

• Rising groundwater levels create greater pressure on the foundations of buildings.
• Cracking and/or movement of concrete slabs/walls will occur.
• Stability will be compromised, allowing water to infiltrate structures.

Erosion of the Soil Beneath the Structure

• Increasing water tables can cause erosion/deterioration of soil beneath a structure.
• Able to affect a structure’s load-bearing capacity; settling/cracking/structural damage may result.

Freeze-Thaw Damage (Even in Miami)

• Though infrequent, occasional cold snaps combined with increased moisture can lead to freeze-thaw damage to concrete.
• Water expands when it freezes, creating small cracks that grow larger.
• Damage may appear as surface spalling and deterioration.

Protective Strategies for Concrete Structures

At North Miami Concrete Pros, we are committed to assisting our customers in adapting to the changing conditions associated with sea level rise. The following are recommendations that we make to protect against the damage caused by sea level rise:

Advanced Waterproofing

• Application of advanced sealants and waterproof membranes.
• Focus on structures below grade and those areas most likely to come into contact with water.
• Perform regular inspections and reapply as necessary.

Corrosion-Resistant Reinforcement

• Use of epoxy-coated/stainless steel rebar in new construction.
• Cathodic protection systems for existing structures.

High-Performance Concrete Mixes

• Inclusion of additives that increase the density and decrease the permeability of the mix.
• Use of supplemental cementitious materials such as fly ash/silica fume.

Elevation/Drainage Improvements

• Raise critical infrastructure above projected flood elevations.
• Precise drainage system design to divert water away from structures.

The Role of Innovative Solutions

At North Miami Concrete Pros, we continually monitor and adopt new technologies to help us combat sea level rise:

1. Self-Healing Concrete: Inclusions of bacteria that produce limestone to repair small cracks.
2. Carbon-Infused Concrete: Absorbs CO2 while curing to lessen environmental impacts.
3. Permeable Concrete: Permits water to flow through the material and lessens surface flooding.

Preparing for the Future

We must take a proactive stance as we face the challenges associated with sea level rise:

1. Assess your property’s risk for flooding and saltwater intrusion.
2. Take into consideration projected future flooding when planning new construction or major renovations.
3. Leverage high-quality materials and hire experienced installers to ensure long-term performance.
4. Remain current on local adaptation strategies and regulations.
