NATURAL AGGREGATE MATERIALS /More details
The location of BAUVAL’s quarries and sandpits provides the company with a diversified supply of high quality aggregates. Natural or processed, stone plays a crucial role in the composition, strength and durability of infrastructures and materials in which it has been incorporated, including cement concrete and bituminous concrete.
All natural sand and gravel pits, granitic aggregates (gneiss), dolomitic limestones (dolomite and sandstone dolomite) or micritic limestones and metamorphic shists have mecanical and chemical properties that meet the requirements of all contractors and agencies and suit all types of infrastructures.
Granites and dolomitic limestones are classified as High-performance Aggregates which are free from alkali-aggregate reactions and comply with the highest concrete production standards. Furthermore, the polishing stone value of these types of aggregates meets the highest standards related to plant mix used for surface courses.
With its various DB (concrete slab) certified, pyrite-free products, BAUVAL provides stone aggregates that do not swell and that are ideal for the construction of foundations, highway and airport slabs, sidewalks, walls, reservoirs and dikes, highly resistant floor framing and buildings.
For example, the strength of the granitic stones found in the Sables L.G. quarry largely exceeds the designed specifications of concrete exposed to acid solutions, detergents, chlorides and freeze/thaw cycles.
Bauval’s clients benefit not only from high-performance aggregates but from a broad expertise and strict quality controls throughout the production process, from mining to delivery.
BAUVAL offers several categories of graded crushed stones that meet the industry’s requirements.
