The versatility of Hydrorock’s “blind” blocks (without plastic channels and connectors) empowered a more innovative, improvised approach to reach a solution; where a high-level design was set but execution was a collaboration between engineers and contractors on site; developing the solution block by block. They understood the characteristics and capabilities of Hydrorock and conceived different ways in which it could be deployed.
Standard density blocks were used in both verges, varying the number of blocks side-by-side to work around obstacles like tree roots, and linked them together using high density blocks stacked three high under the highway. As every block was in contact with at least one other, a large volume unitary aquifer could be created; sufficient to buffer and infiltrate the required volume of run off.
In addition to its flexibility, the speed of installation of Hydrorock meant that the drainage elements of the project completed within the four week timeline.
How important was speed of installation?
