SiteRate Builder Calculator SA

Built by a builder, for South African builders.

SiteRate gives you accurate concrete, brick, block, plaster, roofing,
steel and conversion quantities — straight from your phone, on site,
with no signal needed. Plus, get instant cost estimates based on actual South African big-box store prices.

Most calculator apps get the basics wrong. Wall calculators that don't
subtract windows and doors. Concrete mixes that don't match South African
bag sizes or supplier ratios. Ads between every tap. Subscriptions for
something that should be a once-off purchase.

SiteRate fixes all of that.

WHAT YOU CAN CALCULATE

Free — available to all users:
- Concrete — slabs, footings, columns, by SA standard mix ratios
(15/20/25/30 MPa), with cement bags, sand and stone quantities
- Brick & block walls — accurate counts that properly subtract every
window and door you add, for standard, maxi and concrete block sizes
- Conversions — six instant calculators for SA site work:
- Volume to mass (m³ to tonnes) for sand, stone, soil and more
- Bulk material to wheelbarrow loads (65L barrow)
- Pipe fall and gradient — grade % or ratio to fall in mm
- Surface fall for slabs, driveways and paving
- Roof slope area — plan m² to actual sloped m²
- Run of timber or steel from cross-section and volume

WHY SOUTH AFRICAN BUILDERS USE SITERATE
Generic calculator apps are built for US imperial measurements or
international averages that don't match what you actually buy on site.
SiteRate uses South African brick and block sizes, SANS rebar
specifications, and local mix ratios — so the numbers match what's on
the shelf at your local supplier.

Whether you're a contractor quoting a job, a bricklayer working out a
wall, a plumber checking pipe fall, or a homeowner planning a build,
SiteRate gives you numbers you can trust — and a clean material list
you can act on immediately.
