How do I determine the spacing between joints?

You can use the `calculate_optimal_spacing` tool. Provide the slab thickness, concrete type, reinforcement ratio, base friction, and the expected temperature range.

Can I estimate sealant volume?

Yes, the `estimate_sealant_needs` tool calculates both the total linear meters and the total volume in liters required for your specific slab area and joint dimensions.

How is load transfer capacity assessed?

The `analyze_load_transfer_capacity` tool evaluates the remaining un-cut thickness of the slab against the reinforcement density to ensure structural stability.

This MCP server provides precise engineering calculations for concrete slab contraction joints. It helps engineers and contractors determine the ideal horizontal distance between joints using calculate_optimal_spacing to prevent uncontrolled cracking. It also calculates necessary cut depths with determine_joint_geometry, estimates material needs via estimate_sealant_needs, and verifies structural integrity using analyze_load_transfer_capacity.
