Elevation Change and Drainage

Often before constructing a landscape we need to modify the elevations of the site and fix drainage problems. There are many different kinds of retaining wall that you can use to achieve this. Of these kinds we build:

  • Dry stack basalt. This is probably the most elegant type of material you can use to build a retaining wall up to 5 feet high. It requires no mortar or concrete and is totally self-supporting. People chose this over concrete walls as it blends into the landscape very nicely and looks like it is meant to be there. Also free form shapes and curves, basalt pillars, and lighting can be integrated into the wall in a natural looking way.
  • Alan blocks are another material used to build retaining walls. When built properly these will last for many years and still require no mortar. Curves can be built but they must be gentle to allow for the connection of the wall blocks.
  • Basalt cabin mini stack wall stone. This is for walls under 2.5 feet tall and uses smaller stones. Usually used to separate garden areas from the rest of the landscape these can be a very nice accent to a beautiful garden.
  • Roman stack stones are also used to walls under 2.5 feet tall. These are similar to Alan blocks but smaller and allow for a much curvier style.

For drainage we install simple systems that require little maintenance while removing water from areas of the site with poor drainage. These can be combined with retaining walls to allow for excellent drainage as well as increasing the longevity of the wall.
