Clint from Lattey’s precast yard explained how the Castle PC50/65 is their chosen chair for holding the mesh at the correct level. What they like best is the stability of the large base their resilience when twisting the chair into place, meaning the legs don’t break and most importantly, it maintains the correct cover.
As we know, insufficient concrete cover is one of the main reasons for corrosion of reinforcing in precast structures, very few other building materials have been shown to be as durable as concrete when you compare it with examples existing from the Roman times.
