MICRO REINFORCEMENT

FOR CRACK CONTROL

Boltron uses polyester micro-reinforcement to reduce shrinkage cracking, improve consistency, and strengthen concrete performance.

The Problem

Why Boltron Exists

Standard concrete reinforcement often fails the same way: cracking appears early, control is uneven, and the workflow adds friction.

Failure mode
Micro-cracks appear during curing

Shrinkage and early stress create visible cracking before the slab reaches stable service.

Plastic shrinkage weakens the surface

Fast moisture loss leaves the finished concrete more exposed to surface damage.

Mix quality is harder to keep consistent

Reinforcement that is difficult to distribute can leave performance gaps across the pour.

Steel-based reinforcement adds handling friction

Weight, corrosion risk, and placement complexity make the workflow harder to control.

Dosage can become hard to standardise

If the reinforcement is inefficient, projects consume more than they should.

Boltron response
Controls cracking across the matrix

Boltron is designed to interrupt shrinkage cracking before it propagates through the surface.

Supports a more stable finish

Fine dispersion helps the mix settle into a more even, controlled result.

Integrates cleanly into existing workflows

The fibre format is designed for direct mix compatibility rather than specialist handling.

Removes corrosion from the equation

Polyester reinforcement avoids the maintenance concerns associated with metal fibres.

Keeps dosage disciplined

Low dosage requirement supports a cleaner specification and tighter material control.

The Technology

How Boltron Works

Polyester micro-reinforcement fibres are engineered to distribute through the concrete matrix, forming a fine structural network that controls early-stage cracking and supports consistent slab performance.

Polyester fibre composition

Material choice is deliberate: durable, lightweight, and free from corrosion concerns.

Fine dispersion

The fibre format is designed to spread through the mix without fighting the workflow.

Low dosage requirement

The product is intended to do useful work without demanding excess material.

Multiple fibre lengths

Length options support different reinforcement needs across concrete applications.

Easy integration

The system is specified to fit the mix rather than force a change in process.

Crack control behaviour

The outcome is practical: help reduce early micro-cracking during curing.

The Benefits

Buyer Outcomes

Technical advantages become easier to specify when the language shifts back to what matters on site.

Reduced visible cracking

The product is positioned to interrupt the cracking pattern before it becomes a larger defect.

Simpler handling

Lightweight fibre reinforcement reduces the friction that comes with heavier alternatives.

Cleaner finish consistency

Even dispersion supports a more disciplined surface outcome across the pour.

More predictable behaviour

A structured mix response gives the specification more stability from batch to batch.

Corrosion-free reinforcement

Polyester avoids rust-related concerns that can complicate long-term performance.

Disciplined dosage

A low dosage requirement supports a cleaner, more controlled material strategy.
