| Drenoblock |
| System for collect and elimination of rainwater |
Advantages:
. Reduces rainwater flow rates into the main sewer
. Is the best solution for rainwater elimination in the private, industrial and public sector
. Offers a high collect volume (equal at 95% of the cell volume) resulting in an excavation volume 3 to 4 times lower than in traditional systems where gravel is used
. The system modularity allows to create drainage systems of all dimensions
. Resists to loads caused by traffic
. Is a substantial alternative to concrete absorbing manholes
. Is easy to handle and install

Instructions for installation
Depending on the space, the modules are simply installed one next to the other or placed one on top of the other.
Feeding pipes can be inserted into the Drenoblock system close to the corresponding openings DN160 or other suitable point.
The system is then protected on top and side by a geo-textile cloth and finally covered with excavation soil.
All infiltration systems should take into account the following conditions:
- Distance from the foundations >6m;
- Distance from the groundwater >1m. |
