Calculate the formwork area needed for concrete elements. Enter length, width, and height to find the contact area.

Formwork Area: 120.00 m²
Slab Area: 50.00 m²
Wall Area: 90.00 m²
Total Contact Area: 120.00 m²
Estimated Material Cost: $360.00 (at $3/m²)

Formula: Formwork = 2h(l + w) + (l × w). Add 10% for overlaps and waste.

Formwork Area

Formwork is the temporary mold used to hold concrete in place until it cures. The contact area is the surface area that touches the concrete .
