vibro piles

Our vibro-piles are extremely suitable for a large variety of soil conditions, for which the pile length can be adapted to the supporting capacity of the subsoil. This avoids risks of having piles too long or too short.

Steel tubular piles with a footplate attached to the bottom end can be driven through thick sand strata. After the vibro-tube has reached the correct depth, the inside of the tube is filled with concrete. Subsequently the tube is pulled out and vibrated to shake down the concrete. The counterweight of the pile-driving hammer creates a vibrating effect that results in improving the compactness of the concrete and pushing it firmly against the substrata. This creates the best possible bonding.

With this foundation method, the concrete pile displaces soil. This means no soil is pushed to the surface.

A major benefit is that the diameter, length and number of piles can be adjusted until shortly before the piling operation starts. The

maximum pile length is 35 metres.

By varying the diameter of the pile shaft, the pile loading can be adjusted. Reinforcement over the full length of the pile is also possible. This makes vibro-piles very suitable for high vertical pile loads and tensile strengths.

As a result of the construction method, pile trimming is usually unnecessary. After they have been constructed, all the piles can be checked using acoustic testing.

Another major benefit of vibro-piles is the short lead time, which means the pile driving can be started at short notice.

If necessary, noise nuisance can be further limited by using an IHC type of sound muffler.
