Foundation

• Concrete Slab CalculatorEstimate concrete volume for a slab from its length, width, and thickness.
• Strip Foundation CalculatorTake off concrete, blinding, reinforcement, stirrups, and formwork for a strip foundation, plus the waterproofing and insulation areas and an indicative bearing pressure.
• Bored Pile Foundation CalculatorTake off concrete and steel for a bored pile foundation: pile layout from the building perimeter or by count, pile reinforcement (bars and spiral or stirrups), the grade beam tying the piles with its own bars, stirrups and above-grade formwork, and totals across the whole foundation.
• Raft Slab Foundation CalculatorTake off concrete, blinding, insulation, welded mesh sheets (packed with laps), and edge formwork for a monolithic raft slab, plus the waterproofing area and an indicative self-weight bearing pressure.
• Frost Depth Calculator (Lithuania)Design frost penetration depth for a footing in Lithuania: the SNiP/VGTU formula on STR 2.01.12:2024 climate normals by station and soil type, adjusted for a heated building, shown next to the regulation's own observed maximum frost depths.
• Excavation CalculatorEstimate the dug (bank) and loose volume of a pit or trench with optional side slopes, the compacted backfill after the foundation is placed, and the soil to haul away and fill to import, with truck loads, whether the backfill reuses the excavated soil or is imported.
• Foundation Drainage CalculatorPipe, gravel, geotextile and inspection well quantities for a perimeter foundation drain, plus trench excavation volume.
• Concrete Mix CalculatorCement bags, sand, gravel and water for a site-mixed concrete ratio (by volume or by mass), with a dry-volume allowance.
• Strip Foundation Formwork CalculatorBoards, courses, stakes, braces, ties and fixings for strip foundation formwork, from the outline, height and width.
• Monolithic Floor Slab CalculatorEstimate concrete volume, soffit formwork area, and prop count for a monolithic suspended concrete floor slab.
• Rebar Weight CalculatorConvert reinforcing bar diameter, length, and count into mass for one or more bar entries.
