Erosion control

DOLOSSE, TETRAPODS AND SOLDIER PILE WALLS

Béton Provincial - Dolosses

Dolosse

A dolos is an imposing concrete block in a complex geometric shape, with a variety of uses including protecting harbour walls from the erosion caused by ocean waves. In the eighties, numerous dolosse were installed in the island regions, such as the Magdalen Islands, as part of a widespread sea port protection program.

Each dolos is a fully cast piece, with impeccable finishing standards. Self-levelling concrete is used, providing the structures with a good finish. The concrete mixture must ensure great compressive strength, considering removal from the mould and handling the dolosse are exposed to during the manufacturing process.

TETRAPODS

Like dolosse, concrete tetrapods are used to protect harbour walls from the erosion caused by ocean waves. A tetrapod is a reinforced concrete structure made up of four parts, as in tetrahedral molecules. This structure allows tetrapods to be interlocked, and therefore provide coastal protection.
