2. Pavers (flooring) - Wikipedia

   en.wikipedia.org/wiki/Pavers_(flooring)

   This raised concrete sand helps lock the pavers in place so that they can handle more weight. [9] [10] Concrete sand is a more preferable bedding layer than rock dust. Because rock dust retains rather than drains water, it prevents polymeric sand from drying and curing.

3. Sand reinforced polyester composite - Wikipedia

   en.wikipedia.org/wiki/Sand_reinforced_polyester...

   Sand reinforced polyester composites (SPCs), are building materials with sand acting as reinforcement in the composite.Pioneers in using sand reinforced composites include German business men Gerhard Dust and Gunther Plötner, who made sand reinforced composite bricks with polyester resin and hardener to provide emergency relief housing for those affected by the 2010 earthquake in Haiti.

4. Polymer soil stabilization - Wikipedia

   en.wikipedia.org/wiki/Polymer_soil_stabilization

   Synthetic polymers began replacing other chemical binders for soil stabilization in agriculture in the late 20th century. [1] Compared to traditional chemical binders, polymer soil additives can achieve the same amount of strengthening at much lower concentrations – for example, mixtures of 0.5-1% of various biopolymers have strength levels that match or exceed those of 10% cement mixtures ...

5. Soil stabilization - Wikipedia

   en.wikipedia.org/wiki/Soil_stabilization

   Soil stabilization is a general term for any physical, chemical, mechanical, biological, or combined method of changing a natural soil to meet an engineering purpose. [1] ...

6. Paver base - Wikipedia

   en.wikipedia.org/wiki/Paver_base

   Paver base is a form of aggregate used in the construction of patios and walkways whose topmost layer consists of mortarless (or "dry-laid") pavers. The first layer in the construction of such a surface is called the subgrade —this is the layer of native material underneath the intended surface.

7. Geosynthetics - Wikipedia

   en.wikipedia.org/wiki/Geosynthetics

   The exposed lifetime of geosynthetics, being polymeric, is less than unexposed as when they are soil backfilled. Clogging or bioclogging of geotextiles, geonets, geopipe and/or geocomposites is a challenging design for certain soil types or unusual situations.
