Description Aqualibi water park

Aqualibi is the water park that together with Walibi form a large leisure complex. Sport and fun under a large transparent cover. A space with just the right thermal comfort for any season. A solution for feeling like you’re outdoors. The alternations at the water park included new ETFE covering that covers an area of 3,000 m2


The profile and triple-layer cushions system are attached to the glulam beams. The large octagonal pyramid has a diameter of 48 m. The rapid area, with an elongated ground plan, terminates at its end with a polygonal apse. ETFE sheets have excellent durability and stay transparent over a long time.

Technical Base

ETFE transparent triple-layer cushions

IASO puffy cushion system
It is constructed with two or more closed ETFE laminates in its perimeter and supported with a perimeter anchorage system. Requires an air inflation system in low humidity and at low pressure (250 Pa), which is produced by a unit consisting of fans and air distribution ducts.
IASO solar control system cushions, which by movable intermediate layers and with an upper layer and printed intermediate to modify the passage of light and solar radiation.

What is its dimension?
Normally the circular or square geometry cushions have maximum dimensions of 7.5 m and rectangular cushions should not exceed 4.5 m. The cushion length can reach 40 m. The dimensions can be increased by introducing reinforcement with mesh wire or other materials.

What anchoring system is used?
The cushions are set at the perimeter contour through a system of extruded aluminium profiles. The air tightness of the system is ensured by rubber gaskets. 

What are its design possibilities?
Applications with ETFE sheets allow for unique and imaginative shapes in coverings as well as facades. It enables making imaginative and unique shapes and geometries. The main support structure must be able to be inspired by the planned design of the ETFE enclosure,
collaborating with it as it were.
