🧱 AWWA M23 (Concrete Thrust Blocks at Bends/Tees based on Soil Bearing PSF)

Underground Pipe Thrust Block Calculator

Size cast-in-place concrete thrust restraint blocks and mechanical joint restraint harnesses for underground pressurized water pipelines under AWWA M23 & DIPRA: calculate dynamic hydraulic thrust force (T = 2PA sin(θ/2) at horizontal/vertical bends, tees, and dead ends), calculate required concrete bearing surface area (Sq Ft based on soil bearing PSF), and piping profits.
