Kenya Clay Products is located north of Nairobi along the Thika Road on the left side just before Ruiru. With traffic flowing well, it will take you about 30 minutes to reach there from downtown.
They manufacture many different roofing and floor tile options. The product is made from the big piles of murram that you will see outside the factory. If you would like to see some floor tiles already in use, make reservations to the Mediterraneo Restaurant at The Junction. (020-3878608 or 0734-845077)
Prices are inexpensive. Example: their biggest floor tile cost about KS 28 plus VAT. Service is quick, upon payment they load you quickly.
