Pre-cast Concrete Blocks

Our core business is manufacturing concrete precast rib and block slabs. Reinforcing from 1Y10 to 3Y16 gets cast accordingly, depending on the lattice beam spans. PJ Projects can manufacture ribs of up to 13m long. The engineer will approve all casted ribs/lattice beams. The lattice girder forms a substantial key with the concrete topping. The…

The PJ Projects rib and block concrete slab system are the best choice you can make for your next building project because they make building quicker and more cost-effective. The job is quicker and easier and keeps costs low. The rib and block concrete slab systems make adding a floor quicker and easier. The hollow-core…

A new slab system with precast concrete lattice-reinforced joists began to be developed in Germany in the mid-20th century, using brick blocks as filler, and a cement and sand topping. This new system was introduced in Brazil in the 1940s. The ever-changing requirements of modern architecture, and the growing need for efficiency in civil engineering,…

Pre-cast concrete blocks are made from cement, sand, and gravel, and they tend to get stronger over time, thus make them a great choice for building. Concrete has been used in construction since the late 1800s. It was first used in South Africa when the first reinforced concrete, coal-washing plant was constructed in Vereeniging in…
