The BT 90 is both powerful and simple. A single operator can easily assemble the self-supporting modules of 1, 2 and 3 meters to the required length without the need for special tools. Once in place the BT90 provides deep vibration effect, and thanks to the heavy steel frame it can remove air voids down to a depth of 200 mm.
