Masonry design to Eurocode 6.

Check a loadbearing wall in the time it takes to find the brick strength: Volex computes fk from unit and mortar strength (EC6 Eq 3.1), the slenderness reduction Φ at top, bottom and mid-height including eccentricity (Annex G), and the design vertical resistance with UK National Annex γM.

Validation follows Curtin's 'Structural Masonry Designers' Manual' — the standard UK reference — and the EC6 equations directly, with every case public on the verification page.

Frequently asked

Does it use the UK National Annex?
Yes — γM from UK NA Table NA.1 and the UK values throughout, which is where generic EC6 calculators usually differ from UK practice.
Does it handle slenderness and eccentricity?
Yes — Φ is evaluated at the top, bottom and mid-height with eccentricity per EC6 Annex G, including the Eq G.4 mid-height case.
What about lintels?
Masonry lintels are a dedicated module with their own validation cases.
How much does it cost?
Free tier: 10 calculations/month. Pro: £29/month, unlimited, with PDF calc sheets a checker can audit.
