Concrete fiber dosage calculator

Price the whole package, with your own rates

Four calculators for the four places fiber changes a budget. Nothing is pre-loaded with a Polyguard assumption: every steel price, labour rate, dosage and maintenance interval is an input you control, and nothing leaves your browser.

Four concrete fiber dosage calculators

Industrial flooring savings calculator

Total installed reinforcement cost against a fiber dose.

CurrencyUSD

The slab

Floor area (m²)

Slab thickness (mm)

Conventional reinforcement

Mesh weight (kg/m²)

Steel price (/kg)

Lap & cutting waste (%)

Chairs & spacers (/m²)

Placing labour (/m²)

Concrete volume: —

Steel avoided: —

Steel purchase: —

Chairs & spacers: —

Placing labour: —

Conventional, installed: —

Fiber required: —

Polyguard, dosed: —

Saving per m²: —

Saving on reinforcement: —

Direct saving: —

Indicative only. The dosage must be confirmed by structural design and a trial mix; removing mesh is valid only where the engineering design permits it.

Shotcrete & tunnel calculator

Cost and cycle time per linear metre of tunnel.

CurrencyUSD

Saving per linear metre: —

Total project saving: —

Indicative only. Fixing rates and crew costs vary with ground class, profile and method. Confirm the dosage by design and a site trial.

AsphaltGuard lifecycle calculator

Resurfacings, current interval: —

Resurfacings, target interval: —

Lifecycle saving per km: —

Lifecycle saving: —

The extended maintenance interval is your assumption, not a Polyguard claim. Any change in service life must be verified by mix design and laboratory testing on your own materials.

Precast production ROI calculator

Rejection, rework and handling damage against the annual fiber investment.

CurrencyUSD

Annual production

Concrete volume (m³)

Production value (/m³)

Current losses

Rejection rate (%)

Rejection after fiber (%)

Rework rate (%)

Rework cost (/m³)

Handling & transport claims (%)

Polyguard

Fiber price (/kg)

Result

Annual production value: —

Current rejection loss: —

Rework cost: —

Handling & transport loss: —

Annual fiber investment: —

Fiber cost per m³: —

Rejection cut needed to break even (points): —

Recovered production value: —

Rework & claims avoided: —

Return on the fiber spend: —

Months of benefit to cover the dose: —

Net annual benefit: —

Indicative only. Rework and claims are assumed to fall in the same proportion as rejection — that is your assumption to accept, not a Polyguard claim. The dosage must be confirmed by structural design and a trial mix.

How to use these

Four steps to a number you can defend

Use installed cost, not unit rate

Put in what reinforcement actually costs once it is in the slab: steel, waste, accessories, labour and supervision. A steel price alone will always look cheaper than it is.

Use your real rates

Your steel price, your labour rate, your fixing time. The defaults are only there so the fields are not empty.

Get the dosage from design

The dosage field decides the fiber cost. Ask us for a written recommendation against your mix before you rely on the output.

Send it to us with the drawing

We check the assumptions, flag anything optimistic, and come back with a data sheet and a trial-mix plan.

About the numbers

What these calculators do and do not do

Are the results a quotation?

No. They are arithmetic on the figures you enter, intended for early comparison. A quotation comes with a dosage recommendation, a data sheet and a delivery lead time.

Can I really remove the mesh?

Only where the structural design permits it. The calculator will happily remove the mesh line for you; your engineer of record decides whether that is legitimate.

Where does the asphalt lifecycle saving come from?

Entirely from the maintenance interval you enter. If you have no laboratory evidence for an extension, set both intervals the same and the calculator shows the fiber cost with no benefit assumed.

Does anything get sent to Polyguard?

While you are calculating, your inputs stay in your browser and nothing is transmitted or stored. Nothing reaches us unless you press “Send this result to an engineer” — and then the calculation, together with the contact details you type in, is included with your enquiry.

Price the whole reinforcement package, not the steel

Send the drawing, the exposure class and the loading. You get a dosage recommendation, a data sheet and an installed-cost comparison against your current specification.
