Eskom Security Walls
Modular 2.4 m walls on a robust base, installed without on-site concrete work.
Precast vs Cast-in-situ Concrete
Precast elements are manufactured and cured in a controlled yard and then delivered to site. Cast-in-situ concrete is formed, poured and cured where it will stand. Here is how they compare for typical civil and municipal work:
| Factor | Precast concrete | Cast-in-situ concrete |
|---|---|---|
| Installation speed | Fast: units arrive cured and ready to place | Slower: formwork, pouring and curing on site |
| Quality control | Consistent: made under factory conditions to SANS standards | Depends on site conditions and workmanship |
| Weather | Little impact on the site programme | Rain and heat can delay pours and curing |
| Site labour & disruption | Lower: shorter time with open trenches and road closures | Higher: more workers and longer time on site |
| Best for | Repeated standard elements: pipes, culverts, manholes, kerb inlets, toilet structures, walls | One-off shapes and very large structures that cannot be transported |
