Hydraulic borehole tests

In-situ tests are carried out as part of preliminary hydrogeological investigations to plan efficient drainage systems for tunnel, dam or civil engineering projects or to better assess the risk of possible water inrush.

Solexperts offers high-quality equipment and procedures for hydrogeological in-situ exploration. In addition to the classic Lugeon and pumping tests, we also carry out packer pumping tests, slug, pulse and drill stem tests.
