How do I calculate how much concrete I need for a slab in Canada?

To calculate concrete for a slab, multiply length × width × thickness (all in feet), then divide by 27 to get cubic yards. For example, a 10ft × 10ft × 4-inch slab requires (10×10×0.333)/27 = 1.23 cubic yards. In Canada, add 10% for waste. Our free Concrete Estimator handles bags, sand, gravel, or ready-mix cost estimates for all provinces.

How many bricks do I need per square foot in Canada?

Standard Canadian brick (modular size 194mm × 92mm × 57mm) requires approximately 7 bricks per square foot of wall area when laid with standard 10mm mortar joints. Add 5-10% for cutting and waste. Our Brick Wall Estimator calculates total bricks and mortar quantities automatically.

What is the correct drain slope for residential plumbing in Canada?

The National Plumbing Code of Canada (NPC) requires a minimum slope of 1/4 inch per foot (2%) for drain pipes 3 inches or less in diameter, and 1/8 inch per foot (1%) for pipes 4 inches or larger. Our Drain Slope Calculator helps you verify compliance and calculate the correct rise/run for your drain installation.

How do I estimate electrical load for a Canadian home?

Canadian electrical load calculations follow CSA C22.1 (Canadian Electrical Code). Basic load = 5000W for first 90 sq m + 1000W per additional 90 sq m. Add loads for HVAC, electric heating (100%), ovens (8000W for first unit), dryers (5000W). Our Breaker Load Estimator calculates your panel capacity requirements automatically.
