Key points

Note: This formula has upper and lower limits. P_max should not exceed the full hydrostatic head (ρgh) nor drop below a recommended minimum of about 25 kN/m² for normal pours. You can use this as a LinkedIn article,

) based on factors such as concrete weight density, rate of rise, and temperature, is recognized within BS 5975:2019. For detailed information and to acquire the report, visit CIRIA.  For design detail, charts, curves and worked examples,

Recognizing this gap, CIRIA initiated a research program in the late 1970s, led by A.C. Hargreaves and others, to measure actual lateral pressures during real-world pours. The result was CIRIA Report 108 (1985), which provided:

Calculation: P_max = 1.2 × 24 × 2 × 2 = 115.2 kN/m²
