The use of fish ladders in rivers is a widespread practice throughout the world.
A fish ladder is an artificial structure built in waterways to allow fish to overcome manmade obstacles as they migrate upstream.
ZAPA beton supplied the concrete to build a fish ladder in the Hutský dam along the Sazava river, a tributary of the Moldau. The ready-mix concrete for the construction project was delivered by the Rícany plant. The concrete used was C25/30 XC4 with the addition of a plasticiser agent and later treated with the VZ1 retarder from Sika.

The Rícany ready-mix concrete plant dates back to 2003 and has its own unique image like the company’s other buildings. The plant has received ISO 9001:2009 certification for the production, transport and delivery of ready-mix concrete and mortar mixes for masonry work.
Construction of the fish ladder represents the first step toward protecting fish and their migration.
