Why does a long Karen driveway cost more per metre than a short one?

Falls. Over sixty metres you cannot simply run one continuous gradient: you need intermediate channels and a route to an outfall, and the edge restraint runs both sides for the whole length. The blocks cost the same; the drainage and edging do not.

Which colour works best here?

Charcoal or natural grey. Murram dust from an unsurfaced approach settles on everything, and it is invisible on a dark block and obvious on a pale one. Terracotta looks good on day one and shows both the dust and UV fading within a couple of years.

Plumber in Karen, Nairobi

We cover Karen including Bogani, Hardy, Karen Centre, Miotoni, Marula Lane, Kerarapon, Karen Plains, Mokoyeti, Windridge, Kuwinda. Off Ngong Road and Langata Road via Karen roundabout. Half-acre plots take a ready-mix truck and a tipper directly to the work.

What is different about plumbing in Karen

Karen driveways run sixty to a hundred metres from gate to house, so falls have to be managed over distance rather than set once at the head.
Gate aprons off Bogani Road take turning loads that a straight run never sees, so we specify 80mm there even where the drive is 60mm throughout.
Unsurfaced murram approaches on Karen plots deposit fine red dust constantly, which shows on pale blocks and disappears on charcoal or natural.

Paving in Karen

Karen gives us the longest driveways in the network and the easiest site access. The plot works in your favour; the distance does not.

Falls over distance

A sixty to hundred-metre approach cannot be drained by a single fall from one end. Water picks up volume as it runs, and by the time it reaches the house there is a great deal of it.

We set intermediate channels and cross-falls, with defined routes to a soakaway or an outfall, and we survey levels along the whole run before quoting. Getting this wrong on a long Karen drive means water arriving at the house rather than leaving it.

Turning loads at the gate

The apron in front of a gate takes wheels pivoting while stationary, which loads paving far harder than driving over it does. It is why gate aprons fail first on otherwise sound driveways.

We specify 80mm there as standard, even where the rest of the drive is 60mm. The extra cost is small and confined to a few square metres.

Access is genuinely good

Half-acre plots take a tipper and a ready-mix truck directly to the work, so there is no barrowing and no pumping. That is a real saving against a tight city site, and it partly offsets the extra drainage a long approach demands.

What we are usually called out for in Karen

Cabro paving Cabro laid on an engineered base with edge restraint, the two things that decide whether it lasts. Driveways Driveways in cabro or concrete, with block thickness and falls specified for the actual traffic. Drainage and falls Falls, channels and outfalls designed before laying, because paving concentrates water it did not create. Kerbs and edging Haunched kerbs and edging, the restraint without which paving spreads regardless of block quality.
