Driveway paving in Bryanston
Bryanston driveways are often long and rarely flat. Getting the water off them is as important as the paver you choose.
Built for the fall of the land
Much of Bryanston slopes towards the Braamfontein Spruit, which runs through the suburb on its way to Rivonia. A driveway on that kind of stand acts like a small catchment: it collects rain off itself and off the garden above, and sends it downhill. Where it goes depends on the falls the contractor builds in. If they lead to a channel drain or a planted area, the base stays dry. If they lead to the garage door or the lowest kerb, the base gets wet every storm.

Questions for every contractor
- Where will storm water leave the driveway, and does that drain have somewhere to go?
- What pattern do you recommend for this slope, and why?
- How will the edges be held, especially where the drive is higher than the garden beside it?
- Have you checked the ground at the top and the bottom of the drive?
- What happens to the old driveway and the excavated soil?
Granite soil and water
Bryanston's granite ground has a well-documented weakness: residual granite soils can have a collapsible structure, first described in southern Africa by Brink and Kantey in 1961. Such soil can be firm when dry and settle when it gets wet under load. On a Bryanston driveway, the practical answer is good compaction and keeping water out of the base, which brings the conversation straight back to drainage.
What drives the cost in Bryanston
The contractor quotes you after measuring the job in Bryanston. These are the things that move that quote:
- Length of the drive and the steepness of the slope.
- Number and length of channel drains needed across it.
- Retaining edges where the drive is cut into or built up above the garden.
- Slower working on a steep site, with more care during compaction.
- Removal and cartage of the old surface.

Frequently asked questions
Is herringbone better on a steep drive?
It is often recommended because it locks blocks in every direction. Ask your contractor which pattern they recommend for your slope.
Can a channel drain fix water in my garage?
Often, if it is placed across the drive in front of the door and connected to a proper outlet. Levels need checking first.
Do steep driveways need thicker pavers?
Not always. Base, edge restraint and pattern usually matter more. Ask the contractor to explain their choice.
