Strata Geosystems’ solutions for check dams

The confined infill and textured surface increase hydraulic roughness and reduce near-bed velocity. Slower water movement upstream means less force along the channel edges behind the obstruction. To handle rougher conditions downstream, protective layers at the base and edge need careful shaping.

Reduced upstream velocity promotes sediment settlement. When dams are spaced so that the downstream crest aligns near the upstream toe elevation, a stepped energy-dissipating profile forms. This supports gradual grade stabilization.

Rigid dams are susceptible to cracking under uneven settlement. StrataWeb® distributes loads through a flexible cellular matrix and improves tolerance to minor differential movement. This reduces structural discontinuity in weak or seasonally saturated soils.

Stability comes from confinement-enhanced composite action rather than relying solely on structural mass. Where hydraulics allow, some uses cut back on concrete - or skip it altogether. Concrete amounts shift depending on flow needs across different projects.

Fewer concrete needs mean less need for molds and shorter drying periods because of lighter delivery requirements - efficiency rises where access is tough.

StrataWeb® geocells are manufactured from durable polymeric materials engineered for geotechnical applications. Service life is influenced by polymer formulation, UV exposure, chemical conditions, abrasion potential, hydraulic loading, and long-term creep behavior.

When buried or protected from prolonged UV exposure and installed in accordance with design specifications, the system provides long-term performance with routine inspection and maintenance.

One advantage involves reducing the use of concrete. Reduced transportation requirements can contribute to lower embodied carbon, depending on project design and material sourcing. Locally available fill material often plays a role instead. Disruption at construction sites tends to stay low. The real impact on carbon levels comes from how each project is designed. Long-term analysis shapes the outcome.
