Kilo Wharf, Guam

On the island of Guam in the Pacific Ocean a shore protection has been built. The shore protection has an armourlayer of 8 m3 Xblocs.

The 8 m3 Xblocs on Guam were cast using the horizontal casting method. With this method one nose of the Xblocs is below ground level during casting. This facilitates the pouring of the concrete. During casting the X shaped base of the Xbloc is in a horizontal position and the top of the base mould is not covered. A truck mixer was able to pour the concrete directly in the mould without the requirement of an elevated roadway or crane. Both steel and wooden moulds were used. The mould consisted of 6 parts, a bottom part, 4 side parts and a top nose part.

After hardening the 8 m3 Xbloc is lifted out of the bottom mould using cast in lifting anchors.

The project is constructed by IBC-TOA.
