Design support for drainage systems and drainage trenches

Our external geologists and in-house Technical Department support designers and contractors for landslides, road drainage, foundations, retaining walls, vineyards, “fishbone” layouts and “parallel trench” systems.

We design using patented modules DRENOTER and IDROSAC, sized with the proprietary software DRAINFILE PRO on the basis of the geotechnical and hydrogeological data of the site.

Hydraulic performance of DRENOTER drainage panels

Performance remains constant within the limits specified in the technical data sheet. The panels can be used both as lateral drains and as main collectors in drainage trenches in landslide areas.

Layout of drainage chimneys

Layout of modules as “drainage chimneys”

The “chimney” layout intercepts water inflows in the upper layers above the level of the main collector, improving drainage efficiency in the presence of heterogeneous stratigraphy.

Road drainage

Lateral drainage along the road platform prevents settlements and deformations both on flat terrain and on slopes.

Parameters: trench depth, horizontal earth pressure, required discharge, K, panel discharge under load (calculated with DRAINFILE PRO).

Landslide drainage

Drainage of landslide areas is often the key measure for slope stabilization.

Parameters: depth, earth pressure, rainfall, K, panel discharge (DRAINFILE PRO) vs design discharge.

Foundation drainage

Foundation drainage prevents groundwater from entering underground rooms and basements.

Parameters: foundation depth, earth pressure, K, panel discharge (DRAINFILE PRO) vs required discharge.

Retaining wall drainage

Proper drainage reduces hydraulic thrust and prevents overturning phenomena of the retaining wall.

Parameters: wall height, earth pressure, K, panel discharge (DRAINFILE PRO) vs required discharge.

Vineyard drainage

Control of excess water in the soil protects the root system under extreme rainfall or groundwater rises.

Parameters: trench depth, earth pressure, K, panel discharge and spacing calculation (DRAINFILE PRO).
