Protecting Our Waterways: The Importance of Creosote Abatement

For decades, creosote-treated timber pilings were the standard for docks, piers, and marine structures. While creosote helped extend the life of wood in harsh marine conditions, we now know it comes with serious environmental consequences. As these pilings age, toxic chemicals leach into surrounding waters, threatening fish, shellfish, and delicate ecosystems.

At Trowbridge, we recognize the importance of addressing this issue responsibly. That’s why we use our pile repair technique as an effective method of creosote abatement—treating contaminated pilings in place rather than relying solely on removal.

Why Creosote Abatement Needs to Be Addressed

Creosote contains harmful polycyclic aromatic hydrocarbons (PAHs), which can:

• Contaminate water and sediments.

• Damage spawning and rearing habitats for salmon and other fish.

• Persist in the environment for decades if untreated.

• Pose risks to human health through direct contact with polluted water or seafood.

How Trowbridge’s Pile Repair Technique Works

Our pile repair system is designed to encapsulate and contain creosote within the piling, preventing it from leaching into the marine environment. This approach extends the structural life of the pile while significantly reducing environmental impacts. Key benefits include:

• Environmental Protection: By sealing the contaminated material, harmful chemicals are prevented from spreading. Extended Service Life: The repaired piles gain new strength and stability, reducing the need for costly full replacements.

• Cost-Effective: Treating pilings in place is often more efficient and less disruptive than large-scale removal.

• Regulatory Compliance: Our methods align with environmental standards and best practices for marine infrastructure.

Why It Matters

Creosote abatement through pile repair offers a sustainable alternative to full removal, especially in locations where replacement is difficult or would cause greater environmental disturbance. It allows waterfront structures to remain strong and functional while ensuring waterways are cleaner and healthier for marine life.

Trowbridge’s Commitment

At Trowbridge, we’re committed to protecting marine environments while supporting the infrastructure that communities and industries rely on. Our pile repair technology represents an innovative balance between preserving structural integrity and safeguarding the environment.

Creosote pilings may be remnants of the past, but with proper treatment, we can ensure they don’t define the future of our waterways.
