What are precast walls?
Precast Concrete Wall Panels Precast concrete simply means concrete cast into a reusable mold or “form,” which is then cured in a controlled environment, transported to the install-site and lifted into place. Our precast wall panels make a beautiful addition to any plan.

What is precast beam?
Precast concrete beams and slabs (or planks and joists) is a construction system comprised of precast concrete elements that span in modules between walls and are tied together with rebar that locks into a thin cast-in-place slab. A thin reinforced concrete layer is then poured on top.
What is precast column?
Precast concrete columns may be single or double storey height. Foundation connection may be via a base plate connected to the column or by reinforcing bars projecting from the end of the column passing into sleeves that are subsequently filled with grout. …
