All kerbs are not the same
This article has been supplied.
In 2012 Bosun started manufacturing certain kerbs with the option of having a castellated bottom. These kerbs include the Figure 8C, Figure 7 and Figure 3 kerbs.
We are proud to announce that Bosun was recently awarded a South African Patent (No 2012/09544) for these unique kerbs.
Advantages of Castle Bottom kerbs, compared to conventional kerbs
• The cavities provide a grip for installers when laying the kerbs, which affect much easier handling.
• The cavities make the Castle Bottom kerb much quicker and easier to install. Where unlevel screed surfaces forced installers to uplift, fill up and re-lay conventional kerbs it is easier to maneuver a Castle Bottom kerb into place, with the screed being displaced to the cavities in the kerb.
• Kerbs are laid on a concrete screed. The Castle Bottom will therefore sink into the screed, providing much better adhesion.
• The Castle bottom is less prone to movement after it has been laid on its concrete bed.
• Due to the flat bottom of conventional kerbs, they float on their concrete screed. Their whole surface might therefore not be in contact with the screed where it isn’t perfectly level.
