Concrete Steps – Henley

F A Brothers built a flight of concrete steps outside a factory building in Henley, Oxfordshire.  These were to replace some existing steps which were inadequate.  The approach taken was to build a wooden shuttering (frame) and fill this with mesh steel reinforced concrete.  We also put some vertical bars into the existing concrete steps so that the new concrete would bond to the old concrete.  After the frame had been built and the steel mesh put in place the concrete was poured in and vibrated (with a petrol driven industrial vibrator) to suck out all the air and to give a smooth finish.  Vibrating the concrete prevents air pockets forming (especially next to the wooden frame) and makes the concrete stronger.
