The SafeSeal range stands offer not just durability and quality but an innovative approach to sealing solutions. Central to the SafeSeal Group 2 manhole covers is the 'dry' labyrinth seal, a feature that significantly elevates the performance of these covers against environmental challenges.
A labyrinth seal, as employed in our SafeSeal manhole covers, is designed to maximise sealing effectiveness without the need for additional sealing materials. This type of seal operates on the principle of creating a complex path - akin to a labyrinth - that water or gases must navigate to pass through the seal. The intricacy of this path effectively traps and prevents the passage of water and odours, thereby ensuring a robust seal that maintains the integrity of the manhole cover over time. Figure 1 in our documentation provides a visual representation of this sophisticated sealing mechanism.
