Dave Onderstall who is the sole owner founded Keramicalia in 1989 and has been based in Randfontein since.

At Keramicalia we manufacture a vast range of specialised refractory and moulding materials all of them are unique. 

Keramicalia has  a unique in house Q.A. system aimed at research and development, not focused mass production.

Most of our materials are batched in 8kg to 25kg bags, this means that there is no variation from segregation from bag to bag.

Our data sheets carry a claimer where other manufacturers have a disclaimer to indemnify themselves from non conformity therefore Mr. Onderstall accepts full responsibility for the conformity of each bag produced and sold.

We do not make standard materials or equivalents to other products, If a formulation is not superior in some way, we do not manufacture it.All products are developed in house, from just under 1000 development projects. Our products cover a much wider range of technologies than those of any other manufacturer and are therefore able to supply products more appropriate to each unique application. We have developed a wide range of rapid moulding techniques that can produce many new precast items at one day’s notice.

We have 350 running meters of shelves containing samples of every material we have developed over the years and are kept in a sequential recording system. We can therefore supply your exact requirement or modify the closest material within hours or days to fit your exact requirements.

Keramicalia consists of 5 mini factories, with 10 qualified staff members. That makes turnaround time extremely fast and efficient, making same day production and delivery possible. 


Here at Keramicalia you will find that we have a vast amount of information to answer questions you might have about all the the products we have ever developed
