A. DIY Concrete Pre-cast Wall extensions
a. 300mm or 600mm or 900mm high.
All done by using a Double Slab. A double slab is two slabs cast into one Precast wall slab. So basically 1.44m Length x 600mm High.
Example: Mr A want to raise his precast concrete wall by 2 slabs (600mm), for 15 meters.
· 15 Meters dived 1.5 Meter per section = 10 SECTIONS
· 10 Sections = 11 Concrete Pillars or poles
ü 10 x Double slabs needed @ R125 each = R 1 250.00
ü 11 x 600mm pillars (poles) @ R45 each = R 495.00
Total = R 1745.00
How do I go about it;
Firstly remove your current top concrete slab.
Insert your new Double precast slab.
Clean your old pole top with water. Put on top of pole one cup full of plaster mix.
Insert your new 600mm pole.
Insert your old slab
Plaster slabs on back and finish pole smooth.
And that’s how you do it. At R 174.50 per section this is the cheapest way of doing a wall extension.
