About Concrete and Shielding

During the centuries many improvements have been made to concrete materials. One of the most important improvements made was the introduction of reinforcement into the cementitious material.

It was now possible to use concrete in structural members where tension or bending forces were occurring. Before this innovation, concrete could only cope with compression forces. Starting with the introduction of iron wires and steel bars into concrete, pre-stressed concrete was developed in the 1920's by Freyssinet. These developments made concrete one of the most used materials in the world, with which almost every new structure is built.

Precast manufacturing holds tighter tolerances and precise mixture proportions.
The factory settings greatly reduce waste. That includes waste from excessive concrete, formwork and bracing, packaging and debris that accumulates on typical cast-in-place sites.
Precast manufacturing businesses recycle waste material. That results in less material sent to landfills or dumped into the environment.
Plant conditions create less dust. This is healthier for the environment and workers protected by ventilation equipment and personal protective equipment like respirators.
Properly designed precast concrete products optimise material use. This means less material must be harvested from the environment and results in less to dispose of when the product’s lifecycle is over.
The workplace environment is healthier for factory employees than those who work on construction sites. Internal shop environments have controlled conditions where air quality, noise and safety hazards are addressed.
Most ingredients used in precast concrete are locally produced, and aggregates are mined within a short distance of production. This greatly reduces hauling trips, which decreases highway traffic, fuel consumption and exhaust levels that present a risk to the public.
Energy conservation is a huge factor in creating sustainable products. Durability and operating costs are key tenets of sustainability’s. Our products are durable and designed for long operational life, up to 500 years and are in many instances multi-purpose products, i.e. that can be used for storage, transport and disposal operations.
