Why Do Lampposts and Streetlights Fall Over? The Unexpected Culprit: Dogs

Jul 17, 2024

Urban infrastructure is designed to withstand various environmental factors, from harsh weather to heavy traffic. However, one unexpected culprit contributing to the deterioration and eventual falling of lampposts and streetlights is a more common urban companion: dogs.

As odd as it may sound, the cumulative effects of dogs urinating on these structures can lead to significant damage over time. But just how does this phenomenon occur, and how can we prevent it?

The Chemistry Behind the Damage

Dog urine contains a variety of chemicals, including ammonia and salts, which can be highly corrosive to materials commonly used in streetlights and lampposts, such as metal and concrete. Here’s a closer look at how these components affect these structures:

Ammonia and Corrosion

Ammonia, a compound found in dog urine, is particularly corrosive to metals. When dogs urinate on lampposts and streetlights, the ammonia reacts with the metal surfaces, accelerating the corrosion process. Over time, this weakens the structural integrity of the poles, making them more susceptible to falling.

Salts and Concrete Erosion

The salts present in dog urine are also detrimental, especially to concrete bases. These salts can seep into the porous structure of concrete, causing it to break down and erode. This erosion compromises the stability of the lampposts, increasing the risk of them toppling over.

The Cumulative Effect

While a single instance of a dog urinating on a lamppost may seem harmless, the cumulative effect of multiple dogs repeatedly marking the same spot can lead to significant damage over time. Urban areas with high foot traffic and numerous dogs can see accelerated deterioration of their streetlights and lampposts.

Traditional Materials vs. Resin

Traditional materials used in the construction of lampposts and streetlights, such as metal and concrete, are not well-suited to withstand the corrosive effects of dog urine. Over time, these materials can degrade, leading to increased maintenance costs and safety hazards. However, there is a modern solution that addresses this issue effectively: resin light post bases.

Benefits of Resin Light Post Bases

Resin, particularly Linear Low-Density Polyethylene (LLDPE) resin, offers several advantages over traditional materials when it comes to durability and resistance to corrosion.

Corrosion Resistance: Unlike metal and concrete, resin is non-porous and resistant to the corrosive effects of ammonia and salts. This makes it an ideal material for light post bases that are exposed to dog urine.
Durability: Resin bases are highly durable and can withstand harsh weather conditions, heavy impacts, and the wear and tear of urban environments.
Low Maintenance: Resin light post bases require minimal maintenance compared to their metal and concrete counterparts. They do not rust, crack, or degrade easily, reducing the need for frequent repairs and replacements.
Lightweight and Easy to Install: Resin bases are lighter than traditional materials, making them easier to transport and install. This can lead to cost savings in both labor and material handling.
Environmental Sustainability: Many resin products are made from recycled materials and are fully recyclable at the end of their lifecycle, contributing to sustainable urban development.

A Modern Solution to a Hairy Problem

While it may seem surprising that dog urine can lead to the deterioration and falling of lampposts and streetlights, the chemical composition of urine is indeed highly corrosive to traditional materials. The cumulative effect of repeated exposure can result in significant damage and safety hazards. However, by using durable and corrosion-resistant materials like resin for light post bases, cities can effectively mitigate this issue.

TerraCast® provides innovative resin products that address these challenges, offering a long-lasting and low-maintenance solution for urban infrastructure. By choosing resin light post bases, municipalities can ensure the stability and safety of their streetlights and lampposts, even in areas frequented by our four-legged friends.
