Manufacturer and Supplier of Concrete Rib and Block Slabs
PJ Projects has been manufacturing pre-cast concrete rib and block first floor slabs for more than 20 years. Big enough to provide in all your pre-cast concrete requirements, but small enough to build a relationship with you, PJ Projects has become well-known for its reliability and prompt service.
PJ Projects is situated in Cullinan, just outside Pretoria. We supply pre-cast concrete rib and block first floor slabs to building contractors, developers and individual builders in the whole of Gauteng, Limpopo and Mpumalanga provinces. We deliver in a 300km radius from our yard. Please request a quote here.
Please Note: PJ Projects are only manufacturers of the rib and block material – we do not do installation. However, we can provide clients with the names of trusted installers, who all have extensive experience working with the engineers we use on our projects.
