Sand and gravel

The sand and gravel range comprises a selection of carefully chosen aggregates and hydraulic binders designed for use in mixtures for the construction industry, industrial sanitation and technical filtration systems. This range provides the structural foundation required to carry out masonry, levelling and blast cleaning work with complete efficiency.

Technical particle size distributions and functional versatility in the Sand and Gravel Series

This range stands out for including aggregates with a controlled particle size distribution that ensures optimum compactness in the preparation of mortars and concretes. The presence of high-purity silica-selected particles guarantees the effectiveness of the mixtures in bonding, grouting and ground levelling applications in infrastructure projects.

Their use in mechanical tasks such as surface treatment using compressed air or water filtration in swimming pool treatment systems ensures impurity-free performance. Thanks to the consistency of its grains, you will achieve homogeneous mixtures with a balanced consumption of water and binders, preventing cracks and loss of mass in demanding jobs.

A range of aggregates and binders developed by Grupo Unamacor

Formulated to strict standards by the manufacturer Grupo Unamacor, this range spans from super-fine grain sizes to Portland-based binders for general construction works. You’ll have access to easy-to-handle bagged formats designed to facilitate transport and direct storage on site.

Range of aggregates and materials in the collection

• Fine yellow sand and bound sand in 25 kg bags for the preparation of masonry mortars.
• Technically purified sand in grain size ranges of 0.6–1 mm and 0.6–1.25 mm for swimming pool filters.
• Sand packs for industrial sandblasting in super-fine, fine, medium and coarse grades (0.2 to 2 mm).
• Portland cement with limestone additive, supplied in 25 kg bags, for structural mixes.

Benefits of using graded aggregates in your building projects

Incorporating materials from this range guarantees excellent consistency and strength in every mortar mix or filtration process. You’ll achieve predictable performance that will optimise completion times and ensure long-lasting results in all your renovation projects.
