In terms of outdoor paving options, durability, sustainability, and performance usually make the greatest differences. Today, among numerous available materials, the Black Locust wood can be considered as a top choice for the outstanding resistance of its structure. The idea of locust wood hardness is very important when trying to understand the reasons why such wood is widely utilized in pavings nowadays.

As per information provided by ProFlow Pavers, the Black Locust wood belongs to the category of the most durable and hard woods. This wood is characterized by the Janka hardness index equal to 1,700 lbf, which means that it outperforms many other types of hardwood in terms of both hardness and resistance.

One of the key strengths of the hardwoodiness of Black Locust includes resistance to wear. As the material is frequently exposed to the impact of such external conditions as weather changes, precipitation, and constant use, the latter is likely to lead to dents, scratches, and other forms of wear. However, thanks to the wood being harder, this problem cannot emerge. In other words, the hardness of Black Locust ensures the longevity and visual attractiveness of pavement systems created from this material.

One more feature worth mentioning concerns the inherent resistance to decay and insects. While many other construction materials require pre-treatment to ensure their proper use in the outside environment, Black Locust can be employed right away due to the aforementioned feature.

Apart from high durability, hardness, and insect resistance, dimensional stability is yet another characteristic of Black Locust that ensures the successful installation of pavement systems from this timber. The stability of the wood ensures that it does not change its shape due to moisture content changes.

Furthermore, the importance of sustainability is yet another factor that explains why the Black Locust has been so popular in contemporary architecture. It should be noted that the species matures relatively fast when compared to hardwood trees and is often perceived as a sustainable substitute for tropical hardwoods. What is more, since the wood of Black Locust does not deteriorate easily, there is no need for chemical preservation of the material for a number of decades.

One more reason why Black Locust wood is used in the Permeable Pavements systems by ProFlow Pavers is that it provides a unique combination of strength, attractiveness, and eco-friendly properties. As time goes by, the original gold brown hues of locust change to an attractive silver gray color.

To conclude, the knowledge regarding the characteristics of Locust Wood Hardness enables one to understand why this material is currently becoming so popular in the paving industry. Being sustainable, strong and durable, as well as naturally resistant to decay, locust wood can serve as a great choice for paving. This material is appreciated by ProFlow Pavers precisely due to the above mentioned features.
