About Speed Bump Construction
A speed bump only slows traffic if it's built to the right profile — the height, length and shape matched to the road and the vehicles using it. Too low and it gets ignored; too aggressive and it damages cars and becomes the thing residents complain about. We build tarred, paved and concrete speed bumps for estates, complexes, business premises, industrial yards and parking areas across Germiston, the East Rand and Johannesburg, working out the placement, the profile and the drainage before anything goes down, then marking the finished bump so it's visible day and night. Whether drivers are speeding through your complex, cutting across a parking area too fast, or an existing bump is cracking, too harsh or being driven around, we assess the site and quote the fix.
What's Included
- Site walk finds where vehicles build up speed
- Profile matched to the road and traffic, not generic
- Base excavated and compacted under the full bump
- Built in tar, paving or concrete to match your surface
- Drainage checked and designed in before building
- Channel or gap built in so water keeps moving
- Marked with a contrasting stripe for night, low light
- Bay, directional and hatching lines marked same visit
Our Process
- 1
Site Assessment and Placement
We walk the road or parking area with you, checking where vehicles build up speed, where pedestrians cross, and where sightlines give drivers enough warning to slow down comfortably. A complex or estate often needs more than one bump spaced along the route; a short driveway or tight yard may need only one, well placed.

Base Preparation and Material
We excavate and compact the base under the bump's full footprint, then set the profile — height, length and rounded shape — for the actual traffic using the road. The bump is built in tar, paving or cast concrete to match the surrounding surface, with the same compaction underneath regardless of material.

Drainage Integration
We check where water on that stretch of road is going before we build, so the bump doesn't dam it. Where the road has an existing fall or channel nearby, we tie the bump's edge or a built-in gap into it rather than creating a new low point.
- 4
Marking and Night Visibility
Once the bump has cured, we mark it clearly with a contrasting painted stripe pattern so it's visible to drivers approaching at night or in poor light. We can handle general parking bay, directional and hatching line marking on the same visit.

Speed Bump Construction FAQ
What is the difference between a speed bump and a speed hump?
The terms overlap in everyday use, but there is a general distinction: a speed bump is a shorter, sharper deflection, typically used in parking areas and on private property to force vehicles down to a walking pace, while a speed hump is longer and more gradual, more common on estate and municipal roads where some flowing traffic still needs to get through at a reduced but manageable speed. Both work on the same principle, a raised profile that makes speeding uncomfortable, and both need the same properly compacted base underneath to hold their shape. Tell us how much you need traffic to slow down and what the road is used for, and we will size and build the right profile for your site rather than defaulting to one or the other.
What height should a speed bump be?
There is no single legal height that applies everywhere in South Africa, since sizing is generally set by guidance rather than one national standard, and it varies by municipality and by how much a specific road needs to slow traffic. As a general reference, published South African guidance suggests a rounded profile around 3.7 metres long with a height of roughly 80mm to 120mm, with the lower end of that range slowing traffic to around 50km/h and the higher end closer to 30km/h; some municipalities specify a lower maximum height over a wider profile instead. We use guidance like this as a starting point and size your bump for the actual traffic and vehicles using your road, not a generic figure.
How far apart should speed bumps be spaced?
Spacing depends on the length of the road and how consistently you need traffic to stay slow along it. A single bump only controls speed right at that point, drivers who slow down for it often speed back up immediately afterwards, so a longer stretch of road, an estate's internal loop or a long parking aisle, generally needs more than one bump spaced along its length to keep speeds down consistently rather than one bump doing all the work. We work out spacing on the site visit based on the road's length, bends and where pedestrians actually cross, rather than applying a fixed rule to every property.
What material are speed bumps made from?
We build speed bumps in tar (asphalt), paving or cast concrete, matched to the material of the surrounding surface so the bump ties in properly rather than looking like an add-on. Tarred bumps suit a road or driveway that is already surfaced in tar, paved bumps suit a paved area, and concrete is generally the most durable option for heavy industrial traffic or a municipal-facing road. Whichever material you choose, the base preparation and compaction underneath is what actually determines whether the bump holds its shape, not the surface material on top.
Can a speed bump be installed on existing paving, tar or concrete?
Yes, we regularly build speed bumps into an existing surfaced road, driveway or parking area rather than only on new surfacing. What matters is what is underneath the existing surface: if the base in that section is sound, we can build the bump's profile on top and tie the edges into the surrounding surface; if the base is not adequate for the extra loading a bump creates, we will tell you that on site and quote to prepare it properly first rather than build a bump that cracks or sinks within a year.
