Retaining Walls

Landscaping Walls Nashua NHAn excellent solution to a home landscape that is not perfectly level is to install a retaining wall. There are many different styles and patterns of retaining wall block available throughout New Hampshire. There are many landscape contractors who can construct a wall. A misconception made by many homeowners is that the retaining wall block itself supports the wall. The block actually does very little to hold back the earth behind it. In order to build concrete block retaining walls successfully, the installer must understand soil types and water drainage behind the wall they are building.

Water is the prime shaper of the landscape. A basic component behind any retaining wall is an adequate amount of clean drainage stone and a footing drain to remove the water that results from heavy rain. Without it, pressure from storm water will build up behind the wall and push the wall over. Many concrete retaining block systems have pins, tabs or tongue and groove concrete molded into the block- but these mechanisms are simply locators to help keep the wall straight during construction. Redirecting storm water flow is the first priority in building a wall that will last.

How much earth will a retaining wall hold? The answer to this question depends on several things. How steep is the slope behind the wall? What type of soil is on site? Is it a “cut wall” or a “fill wall?” When a terraced retaining wall is desired, how close can walls be to each other? As you can see, the solution to leveling the landscape in your yard successfully is a little more involved than picking a style and color of concrete retaining block that you like the best.
