Expertise with geocells

Deep muskeg soil.

Access and Haul Roads

Stratum designs access roads that can be built directly over swampy muskeg, often utilizing locally available materials (e.g. sand). By alleviating the need to import costly aggregates this saves time and hauling costs. Additionally, by using geosynthetic reinforcements, Stratum builds roads that drastically reduce the need for ongoing road maintenance and/or seasonal replacement.

Soft soil.

Expansive Clays and Soft Soils

Stratum conducts detailed geotechnical and hydrological investigations to predict the extent of expected ground movements to inform the design of appropriate mitigation measures.

Whilst settlement cannot be prevented, differential settlement can be attenuated through “peak shaving” methods thus creating a “beam effect” that:

  • ensures lower and longer amplitudes
  • reinforces the integrity of foundations and ground slabs and improve IRI in pavement structures

In many cases, Stratum is able to substitute costly soil replacement with geotechnical designs using advanced geosynthetic materials.

Frost Heave

Frost-heave is a common problem in areas where the ambient temperature falls below freezing during winter. The problem becomes severe when it is compounded with a poor subsoil condition and high water table.

Stratum uses structural NPA (novel polymeric alloy) geocell reinforced granular layer(s) beneath the surface to minimize the impact of moisture in subsoils. The accumulating moisture is continuously drained and redirected while in a liquid state.
