Product Overview

Summary: This Polymer Modified Concrete Procedures Safe Operating Procedure provides a clear, step‑by‑step framework for safely batching, placing, finishing and curing polymer modified concrete in Australian workplaces. It helps your team manage the unique chemical, thermal and structural risks associated with polymer admixtures, while delivering consistent, high‑quality concrete performance that meets project and WHS requirements.

Polymer modified concrete (PMC) is widely used across Australian infrastructure, building and remediation projects for its enhanced bond strength, durability and chemical resistance. However, the introduction of polymer admixtures, bonding agents and specialist curing systems also brings new safety, quality and environmental risks that are not adequately covered by generic concrete procedures. This Safe Operating Procedure provides a structured, practical guide for managing those risks at every stage of the work – from material selection and storage through to mixing, placement, curing and clean‑up.

The document translates WHS and technical requirements into clear actions for supervisors and crews on the ground. It addresses hazards such as exposure to polymer resins and solvents, exothermic reactions, slip and trip risks from polymer‑rich surfaces, and potential structural defects if mix proportions or curing regimes are not followed. At the same time, it supports consistent quality outcomes by standardising mix verification, substrate preparation, application methods and inspection criteria. Implementing this SOP helps Australian businesses demonstrate due diligence under WHS legislation, reduce rework and warranty claims, and protect both workers and assets during polymer modified concrete works.

Key Benefits

• Ensure safe handling, mixing and placement of polymer modified concrete in line with Australian WHS obligations.
• Reduce the risk of chemical exposure, burns, slips and structural failures associated with polymer admixtures and bonding systems.
• Standardise work methods across crews and sites, improving consistency of finish, bond performance and durability.
• Streamline training and onboarding for new workers and subcontractors involved in polymer modified concrete works.
• Demonstrate compliance and due diligence to clients, regulators and auditors through a documented, defensible procedure.
