We are paving the garden for parking. Any downside?

Drainage. A garden absorbs rain and paving does not, so you are creating runoff that has to go somewhere. On a converted Kilimani plot with no spare outfall, that usually means a soakaway or permeable construction, and it needs planning before the blocks arrive, not after.

Why is pumping concrete an extra?

Because it needs a pump and an operator on site. On a tight Kilimani plot a loaded ready-mix truck often cannot reach the pour, and pumping is the alternative to barrowing several cubic metres. It is a real cost and we survey access before quoting rather than after.

Plumber in Kilimani, Nairobi

We cover Kilimani including Yaya, Dennis Pritt, Wood Avenue, Rose Avenue, Chaka Road, Ring Road Kilimani, Kirichwa, Milimani, State House. Off Argwings Kodhek Road, Ngong Road and Denis Pritt Road. Tight sites frequently mean concrete is pumped rather than discharged.

What is different about plumbing in Kilimani

Kilimani sites off Dennis Pritt Road are tight enough that a ready-mix truck cannot reach the pour, so concrete is pumped and priced that way.
Blocks near the Kirichwa discharge surface water into a storm system that already runs full in the long rains, so a soakaway is often the more reliable outfall.
Converted houses around Argwings Kodhek Road pave former gardens for staff parking, which turns absorbent ground into runoff overnight.

Paving in Kilimani

Kilimani is dense, redeveloped and increasingly paved, and every square metre of new paving here adds to a drainage problem the area already has.

Where the water goes

The storm system serving much of Kilimani runs at capacity during the long rains. Connecting a new paved area to it is frequently not a real solution, because there is nowhere for the water to go once it arrives.

So on most Kilimani jobs we design for a soakaway, or for permeable construction with an open-graded sub-base that stores water and lets it infiltrate. It costs more than a channel and a connection, and it works.

Gardens becoming car parks

Converted houses around Argwings Kodhek and Milimani routinely pave former gardens for staff and visitor parking. That converts absorbent ground into runoff in a single week.

We would rather raise it at quotation than have a client discover in April that the neighbour’s compound is now taking their water.

Access and pumping

Tight sites mean a ready-mix truck frequently cannot reach the pour. Pumping is the alternative to barrowing, and it is a predictable cost we survey for rather than discovering on the day.

What we are usually called out for in Kilimani

Cabro paving Cabro laid on an engineered base with edge restraint, the two things that decide whether it lasts. Drainage and falls Falls, channels and outfalls designed before laying, because paving concentrates water it did not create. Concrete slabs and hardstanding Yard slabs, parking bays and hardstanding, jointed and cured properly rather than poured and abandoned. Ready-mix supply Ready-mix supplied and placed, with the class specified and the volume calculated rather than guessed.
