Precast Walling Prices per Metre (2026)

Prices checked October 2026 against published installer prices in Gauteng and Cape Town, including Precast Walling Pros. We are asking Local Pros partners for their current prices and will update this table.

Precast walling prices per metre (installed)

Cape Town prices tend to sit at the lower end of these ranges. Prices in Gauteng are often a little higher for the same height.

What South Africans asked us for

Since May 2024, Local Pros has received more than 1,600 requests for precast walling quotes. This is what people needed:

Job	Share of requests
New wall, 10 – 30 m	38%
Repair to an existing wall	19%
New wall, 30 – 60 m	17%
New wall, 60 m or longer	15%
Extending an existing wall	10%

• Most common job: a new wall of 10 to 30 metres, usually a back or side boundary.
• Busiest months: July, August and September. February is the quietest, so installers may have more time then.
• Where people asked most: the East Rand, Johannesburg, Alberton and Joburg South, the West Rand and Pretoria.

Precast slab sizes and how many you need

A standard precast (vibracrete) slab is about 1,440 mm long and 300 mm high. Posts are usually 130 mm × 130 mm, so each section between posts is roughly 1.57 m.

Wall height	Slabs high	Slabs per 10 m of wall
1.2 m	4	about 28
1.5 m	5	about 35
1.8 m	6	about 42
2.1 m	7	about 49
2.4 m	8	about 56
2.7 m	9	about 63

Buying slabs yourself (supply only)

Builders' merchants such as Cashbuild, Builders and Leroy Merlin sell precast slabs and posts, but stock varies by store. Precast factories also sell direct.

Doing it yourself saves on labour. The posts must be concreted in straight and level, though, or the wall will lean.

Most installers include delivery within about 30 km of their yard.

Types of precast walling

• Plain or standard: the most affordable option. It can be painted.
• Louvre: thin horizontal slabs, priced like plain walls.
• Crushed clay / brick look: looks like face brick and never needs painting. It is a mid-range price.
• Jumbo: large slabs that install quickly and give good privacy. Usually priced like plain walls.
• Heavy duty: thicker, reinforced slabs for high-security walls, usually 2.4 m to 2.7 m. This is the most expensive option.

What else affects the price

• Removing an old wall or fence and taking the rubble away.
• Sloping ground: the wall has to be stepped, which needs extra slabs and posts.
• Access: if trucks cannot get close, slabs are carried in by hand.
• Security on top: spikes, razor wire or electric fencing.
• Gates for pedestrians or vehicles. See driveway gates.

Repairs and extensions

Almost one in five requests we get is for a repair. Common repairs are replacing broken slabs and re-setting posts that lean after heavy rain or tree roots.

Repairs are usually quoted per job, so send photos when you ask for a quote. Extending a wall costs about the same per metre as a new wall, as long as the slab style is still available.

Precast walls compared with other boundary options

Precast walls give privacy, while Clear View fencing and steel palisade let you see through. Concrete palisades are a see-through option made of concrete.

Frequently asked questions

What is the standard size of a vibracrete panel?

About 1,440 mm long and 300 mm high. Six slabs give a 1.8 m wall, and eight give a 2.4 m wall.

Is a precast wall cheaper than a brick wall?

Usually, yes. A precast wall needs less labour and goes up in a few days.

A plastered brick wall costs more per metre and takes longer to build, but it is stronger and can be built higher.

How long does a precast wall last?

A well-installed precast wall lasts for decades with very little maintenance. Most problems come from posts that were not set deep enough, or from ground movement.

Do I need approval to build a precast boundary wall?

Check with your municipality before you build. Higher walls and walls on a street boundary may need approved plans, and some estates have their own rules.

Can I buy precast walls at Cashbuild?

Many Cashbuild, Builders and Leroy Merlin stores sell slabs and posts, but stock differs by store. For a full wall, an installer usually gets better prices from the factory and includes delivery.
