Continuous innovation
in the dosing of additives

The dosage taylored to every need

We are a company born more than forty years ago when the additives were still poured manually. The stubbornness and desire for innovation has meant that year after year we have always created new products that are suitable for the needs of the market.

La Serena has designed custom-made products that respond to the required peculiarities. Hand in hand with a practical and technological development, it has created a network of personal relationships within a vast clientele, making every need and individual characteristic unique.

Our strengths are product quality, customer care and listening, building a dialogue together to obtain the best doser.

Our products

  • Dispenser
    for asphalt additives

    With our products we also take care of the dosage of bitumen for asphalt, a very different product from that used for concrete. We have therefore designed and created a new range of dispensers that handle more corrosive and thicker additives without problems.
