Strength and durability
Higher cement content, low permeability and aggressive-environment specifications typically add £15–£80/m³.
Pour volume
Small pours, part-load charges and repeated mobilisation can increase the effective rate by £35–£120/m³.
Pumping logistics
Long pipelines, additional pump attendance or specialist boom requirements commonly add £10–£45/m³.
Element complexity
Thin sections, congested reinforcement and difficult vibration can raise placing costs by 10%–25%.
Programme constraints
Out-of-hours working, short-notice bookings and accelerated pours may increase the rate by 10%–20%.
Location and access
Regional supply conditions, urban delivery restrictions and extended haulage can move rates by £15–£50/m³.
