Both calculators run independently — change the inputs on either side to compare results.

Slope Stability Calculator

Compute the factor of safety against sliding failure on an infinite slope using soil strength and groundwater parameters. Used by geotechnical engineers assessing embankments, hillside cuts, and natural slopes.

Concrete Volume Calculator

Estimate the in-place concrete volume for slabs, footings, walls, and other rectangular structural elements using V = L × W × T. The geometric volume in cubic metres — add 5–10% waste before placing the order.
