OUR MISSION
At POLY ROADS KZN, we take great pride in successfully connecting clients with the Smart Materials they need to build tomorrows world. This does not, however, come second to our responsibility to protect todays world. The Smart Materials we offer are purposely designed and manufactured in ways that address environmental challenges. All our products are developed to the highest environmental standards.
Smart Materials challenge the core fundamentals of conventional road design, construction and costs. This is why we remain engaged throughout the entire process to ensure that quality standards are maintained through environmentally responsible practises.
SMART MATERIALS
Minimising the use of Crushed Stone
SoilTech polymers has been specifically engineered as binders to be used with in-situ materials, thereby reducing conventional road construction aggregate by up to 80%. Not only do SoilTech polymers reduce aggregate requirements, but it also reduces construction time and thereby realises substantial savings in the costs of road construction. SoilTech polymers will strengthen most soils and aggregates. Formerly discarded materials can now be used in the construction and layer-works of the road. Limited amounts of borrow pit or quarry materials need to be brought in. SoilTech layers are flexible and dramatically increase indirect tensile strengths of construction materials, thereby reducing the normal supporting layers that conventional cement stabilized layers require.
Reduced layer works, means reduced construction time, shorter machine hours, resulting in more economically road construction.
Engineers are now able to construct roads in remote areas that are void of decent materials for road construction. Furthermore Smart Materials are able to bind, virtually any non-plastic materials into a viable and cost effective wearing course seal.
Smart Materials are ideal for international donor projects for roads in developing countries.
Smart Materials have been designed to be environmentally friendly and is the green solution for 21st Century construction projects.
SMART MATERIALS REDUCE CARBON EMISSIONS BY 97%.
GREEN HOUSE GASES (GHG)
Carbon Emission Pollution
Conventional road design and stabilization consists of a cement stabilized sub-base, preceded by multiple supporting sublayers of aggregate of fill materials. A one kilometer section of road, measuring seven meters wide, with a cement stabilized layer, using 4% of cement per weight of the aggregate, at 150mm deep, will consume approximately 84 tons of cement which equates to 75 tons of CO2 released into the air and that is only from manufacturing of the cement. This figure excludes the calculated the fossil fuel CO2 emissions during the construction of the cement stabilized layer, nor the CO2 emissions released during the curing period of the cement stabilized layer.
SOUTH AFRICAN CONTEXT.
Environmental impact of road construction.
Of the 750 000 km of roads in South Africa approximately 600 000 are un-surfaced gravel roads. Every year, more than 150 million tons of gravel (equal to the size of Table Mountain in Cape Town) are stripped from their roads and have to be replaced.
Poly Roads KZN offers a unique solution to prevent this kind of excessive loss. It is our personal and environmental responsibility to make this solution as accessible as possible.
