Robinia wood, often hailed for its natural appearance and durability, has become a popular choice for playground equipment. Its rustic charm blends seamlessly with outdoor settings, making it an appealing option for creating natural-looking playgrounds. However, despite its many advantages, there are significant issues associated with the use of Robinia wood, particularly concerning rot and cracking. These problems can compromise the safety and longevity of playground structures.

Hidden Rotting in Robinia Wood

One of the most insidious problems with Robinia wood is its tendency to rot from the inside. Unlike more predictable types of wood rot, which often start from exposed surfaces and can be easily detected and treated, Robinia wood can rot internally.

This type of rotting is particularly dangerous because it is not visible on the surface, making it difficult to detect until significant damage has already occurred. This hidden rot can weaken the structural integrity of the playground equipment, posing serious safety risks.

Cracking and Splitting Issues

Another major issue with Robinia wood is its propensity to develop large cracks and splits. These cracks can occur naturally as the wood dries and contracts. Over time, the cracks can become extensive, further weakening the structure and potentially creating sharp edges that can cause injuries.

The following images highlight the severity of this issue. The second image shows a significant crack running along the length of a support beam, which not only undermines the wood’s structural integrity but also presents a physical hazard to children playing nearby.

Robinia wood exhibits deep splits, which can be particularly concerning if they occur in weight-bearing components of playground equipment.
