Construction costs have gone up, but geosynthetics keep costs down
The prices of crude oil and gas have inclined steadily. The trend has been felt by manufacturers and end users involved with geosynthetics. Costs are rising in all construction material fields but the overall project cost-savings that are realized through geosynthetics remain steady. Some cost savings are direct (e.g., less need for soil excavation/replacement), and some are long-term (e.g., reduced maintenance, extended life). Key to figuring much of this lies with understanding the interaction between the soil and geosynthetic, understanding the geosynthetic's function, and keeping in mind that geosynthetic materials can be engineered to specific site circumstances. Consider that soils contain a number of common flaws, including non-uniform particles, natural instability in the subgrade, moisture inconsistency problems (e.g., swelling/shrinking, loss of strength), and poor tensile strength. Traditional approaches to redoing these soils are costly. Geosynthetics provide stable options supported by performance data to improve drainage, supply greater confidence in expected settlement, and mitigate problems such as frost heave. Examples for successful applications of geosynthetics are clay liners that can reduce the amount of compacted clay beneath an environmentally sensitive containment installation, and paving fabrics that reduce reflective cracking and extend the life of the roadway.
