All the tanks built that will service throughout the salmon life cycle will be made of concrete on site. The structures are made of different geometries and heights, the most important ones being a set of 10 tanks with walls up to 6 meters high. This makes the formwork process more difficult due to the high pressure exerted by concrete poured into formwork at such height. In addition to the technical issues related to the formwork height, the great challenge for Alsina has been to provide a large amount of material needed for the work in record time.

Alsina: practical and efficient formwork solutions

For the implementation of the project, Alsina provided its Alisply Walls and Alisply Circular formwork systems.

The Alisply Walls modular formwork system is a resistant, versatile and compatible system in its accessories with each of the Alisply family systems. This makes the use of the equipment onsite very profitable. The formwork surface of the Alisply system is phenolic; therefore, it offers multiple advantages over metal surfaces, such as lower weight, greater quality of the concrete, increased performance and greater resistance to inclement weather.

Alisply Circular is a reusable modular formwork system   for circular walls made of finished concrete. It is a fast and cost-effective system designed to be used with a crane, consisting of a galvanized steel frame and a phenolic resin-coated plywood surface. The modules of the system come pre-assembled from the factory and during construction it is only necessary to give the required radius. The panel includes the necessary components and does not require any special tool to curve the plywood.
