Volex Labs / Calculations / Reinforced concrete ground beam design to Eurocode 2.

Reinforced concrete ground beam design to Eurocode 2.

Enter the span between supports and the wall/ground loading, and Volex Anvil designs the ground beam: the design sagging moment and shear, the flexural and shear reinforcement to EC2, and the deflection — for beams carrying superstructure loads down to pads or piles.

Ground beams also resist heave and ground-bearing effects; the design reports the moment and shear envelope and the reinforcement so both the span and support conditions can be checked.

Frequently asked

Does it allow for ground heave?
Yes — where a void former or heave case applies, the reversed (hogging) moment can be checked in addition to the gravity sagging case.
Between pads or piles?
Both — the beam is designed for the clear span between supports, whether pad foundations or pile caps.
Is it validated?
The design moment and shear are checked against statics — within 0.03%.
Free to use?
Yes — 10 calculations a month free; Pro (£29/month) adds unlimited runs and PDF calc sheets.
