Plastic cribbing is resistant to contamination from fuel and oil
Plastic cribbing is a type of cribbing material used in construction, particularly in excavation work. It is known for its ability to resist contamination from various substances, including fuel and oil, which makes it suitable for use in environments where it might be exposed to such contaminants. This is in contrast to wood cribbing, which is porous and prone to biohazard concerns, splitting, splintering, and knots.
Plastic cribbing's resistance to fuel and oil contamination is due to its nonporous nature. Unlike wood, plastic is impervious to fluids and will not absorb oils or other hazardous liquids. This is an important characteristic, as it prevents the plastic from becoming a source of contamination itself and helps to maintain the integrity of the structure.
The nonporous nature of plastic cribbing also has other benefits. For example, it can help to prevent the growth of bacteria, which is important in maintaining sanitary conditions. Additionally, the smooth surface of plastic cribbing can make it easier to clean and maintain, further reducing the risk of contamination.
The resistance of plastic cribbing to fuel and oil contamination is particularly important in certain applications, such as in the storage of gasoline and oil. There are many safety regulations to adhere to when storing these substances, and the use of plastic cribbing can help to alleviate some of the risks associated with their storage, such as leaks and vapors.
Overall, the resistance of plastic cribbing to contamination from fuel and oil is a significant advantage over other types of cribbing, such as wood. This characteristic makes it a valuable material in construction and other applications where exposure to contaminants is a concern.

It is non-porous
Plastic cribbing is non-porous, which means it is impervious to fluids and resistant to contamination from fuel, oil, or other substances. This is in contrast to wood cribbing, which is porous and can absorb fluids, leading to biohazard concerns and a weakening of its structural integrity. The non-porous nature of plastic cribbing also makes it more durable and capable of holding heavier weights compared to wood. It can withstand up to 1,200 PSI, or nearly 60,000 lbs, and typically holds two to three times more weight than wood cribbing.
The non-porous property of plastic cribbing also contributes to its longevity. Plastic cribbing is less prone to deterioration and can last for years longer than standard wood. Its synthetic composition makes it resistant to rotting and other forms of degradation that can affect natural wood. This extended durability can result in cost savings over time, as fewer blocks may be needed for the same job, and the cribbing can be reused multiple times without needing to be replaced.
The ability of plastic cribbing to resist fluid absorption also makes it a safer option in certain situations. For example, in rescue operations or vehicle extrications, the use of non-porous plastic cribbing can help prevent the spread of hazardous fluids and reduce the risk of contamination. This characteristic can be particularly advantageous when dealing with fuel or oil spills, as the plastic material will not absorb these substances, making cleanup and containment easier.
Additionally, the non-porous nature of plastic cribbing allows for more flexibility in manufacturing and customization. Unlike wood cribbing, which is typically limited to standard dimensions of commercially-sold wood products, plastic cribbing can be manufactured in any desired dimension. This adaptability allows for a more precise fit and stability when cribbing uneven or irregularly-shaped objects. Furthermore, the manufacturing process of plastic cribbing allows for the inclusion of small pyramid-shaped protrusions or "Lincoln Log" type ridges, which can enhance the stability of the cribbing by providing a better grip on surfaces such as ice and snow.
While the non-porous nature of plastic cribbing offers significant advantages, it is important to consider the trade-offs. Plastic cribbing is generally more expensive than wood cribbing, and there may be environmental concerns associated with the use of plastic materials. Additionally, the potential for slippage on icy or snowy surfaces is a factor that needs to be carefully addressed through design considerations, such as the inclusion of protrusions or ridges that improve grip. Overall, the non-porous characteristic of plastic cribbing makes it a durable, versatile, and reliable option for various applications, particularly in situations where fluid resistance, weight-bearing capacity, and stability are critical factors.

Plastic cribbing is more expensive than wood
The manufacturing process and dimensions of plastic cribbing also contribute to its higher cost. Plastic cribbing is typically made from recycled plastic materials, such as milk jugs, which are pelletized, heated, and compressed into the desired shape. This allows for greater flexibility in terms of dimensions, as plastic cribbing can be manufactured in any size or shape to meet specific requirements. In contrast, users of wood cribbing are limited to standard commercial dimensions, such as 2x4, 4x4, or 6x6 pieces.
The debate around the cost of plastic cribbing compared to wood also extends to its performance in different weather conditions. Some firefighters have raised concerns about the potential for plastic cribbing to slip in cold, snowy, and icy environments. However, field tests have shown that plastic cribbing with textured surfaces can outperform wood cribbing in similar conditions, as the protrusions can "bite" into the ice and snow for better grip and stability.
While plastic cribbing may have a higher upfront cost, its superior durability, weight capacity, and customisability make it a more reliable and efficient choice for certain applications. Additionally, the longer lifespan of plastic cribbing can offset its initial expense, as it may require less frequent replacement compared to wood. Ultimately, the decision between plastic and wood cribbing depends on the specific needs and budget constraints of the user, as well as the environmental factors that may impact the performance of the material.
