Introduction:
Seawall Failures and Effective Seawall Repair Strategies
Over the passage of time, even the sturdiest seawalls can exhibit cracks, becoming susceptible to water penetration. In certain scenarios, the very foundation of the seawall might shift due to the erosion of its supporting substrate. Proactively identifying and rectifying these concerns can stave off escalated damage, ensuring the seawall remains a steadfast defense against water and erosion.
Whether for private residences or commercial establishments, many seawalls are crafted with similar design principles. Their upkeep and restoration can be effectively managed using hydro-active, hydrophobic polyurethane foams for leak-sealing and water-stopping, as well as two-component or dual-component polyurethane foams for void-filling and elevation.
When it comes to repairing structural concrete damages and concrete spalls in seawalls and marine piles, epoxy injection resins can be a reliable option. These resins can provide long-lasting reinforcement to the affected area, helping to ensure that the seawall or pile can continue to withstand the stress and impact of waves and tides.
Understanding why seawall failure occurs and taking timely steps to prevent further damages is important to protect your land and any structures that may be impacted by ingress of water and shifting soils.
Why Do Seawalls Fail?
Causes & Warning Signs of Seawall Failure
- Poor Maintenance | Lack of Inspection to Detect Problems Early
- Erosion, Washout, Sinkholes
- Footing, Bulkhead Shift Due to Erosion
- Cracks and Expanding Cracks in Seawall
- Rust & Corroded Rebar Expansion
- Drain Failure
- Environmental Factors – Natural Disasters
Regular and Proactive Inspections and Maintenance: A Key Strategy to Prevent Seawall Damage
Executing frequent inspections and prompt maintenance are integral to extending the lifespan of your seawall. These preventative measures can save you from costly repairs in the long run by addressing potential issues before they escalate.
A significant issue you may encounter is the clogging of drain and weep holes. These are crucial components in the seawall’s design as they allow water accumulated behind the wall to drain. If clogged, water will build up, leading to added stress on the seawall and potential damage. This accumulation of water can soften and loosen the soil behind the wall, which could increase pressure and raise the water table. Such conditions might result in the formation of cracks in the seawall structure, thus creating new, unintended pathways for water flow and consequently causing soil erosion.
Understanding the Implications of Soil Erosion due to Accumulated Damages
Water migration through these new pathways, cracks, voids, and defects can lead to a gradual weakening of the seawall. As the wall undergoes consistent damage and erosion, its foundation may lose support and shift. This can be particularly problematic because soil erosion has the potential to create sinkholes. These sinkholes can further collect water, accelerating the decay process and potentially leading to the seawall’s failure.
Hence, regular inspection and maintenance can help identify early signs of soil erosion and structural damages, thereby preventing severe consequences and ensuring the longevity of your seawall.
