Trench Fill Foundation Calculator: Estimate Concrete, Rebar, and Costs Trench fill foundations—also known as trench fill footings—are a common and cost-effective solution for supporting domestic extensions, garden walls, and light commercial buildings. Unlike traditional strip foundations with separate footings and walls, trench fill involves excavating a trench and filling it almost entirely with concrete, often…
Gravity Retaining Wall Calculator: Estimate Blocks, Concrete, and Costs Gravity retaining walls are among the oldest and most reliable structures for holding back soil. They rely on their own weight to resist the lateral pressure of the retained earth. Whether you’re building a garden wall, a driveway edge, or a small agricultural terrace, getting the…
Raft Foundation Calculator: Estimate Concrete, Reinforcement, and Costs A raft foundation—also known as a mat foundation—is a thick reinforced concrete slab that spans the entire footprint of a building, distributing loads over a large area. It is used where soil conditions are poor, where differential settlement must be minimized, or where basements are required. Designing…
Pile Capacity Calculator: Estimate Shaft Friction, End Bearing, and Settlement Piles are deep foundation elements used to transfer structural loads through weak upper soil layers to stronger, more competent strata at depth. They are essential for supporting buildings, bridges, and industrial structures where shallow foundations would be inadequate. Designing a pile requires determining its ultimate…
Ventilation Airflow Calculator: Determine Required Airflow and Duct Size Ventilation is essential for maintaining healthy indoor air quality. Whether you’re designing a bathroom extract system, a kitchen ventilation hood, or a whole-house MVHR system, you need to know how much air must be moved and what size duct will carry it efficiently. Too little airflow…
MVHR Sizing Calculator: Estimate Airflow, Ducts, and Costs Accurately Mechanical Ventilation with Heat Recovery (MVHR) is the gold standard for energy-efficient ventilation in modern homes. It continuously supplies fresh filtered air to living spaces while extracting stale, moisture-laden air from kitchens and bathrooms, recovering up to 95% of the heat in the process. But sizing…
Extract Fan Sizing Calculator: Choose the Right Fan for Bathrooms, Kitchens, and More Extract fans are essential for removing moisture, odours, and pollutants from bathrooms, kitchens, utility rooms, and other spaces.
