In contrast, conventional pre-cast road kerb construction has various shortcomings:
Tendency to deteriorate rapidly and quickly exhibit signs of wear and tear due to weak concrete strength and hollow structure resulting from lack of compaction
High labor cost
High maintenance cost within a fast cycle of 5 – 10 years
High wastage of material
Longer completion times with only 40-90 lin meter completed in a day
Limited kerb profile designs
Unattractive designs with the obvious appearance of visible joints and rough surfaces
Difficulties in leveling during construction/ forming of kerbs as the kerb-block needs to be planted adjusted and manually placed. |
