Erosion is a natural, but potentially destructive process in which soil is actually washed off your property.  This erosion can result in damage to trees, shrubs, and other plantings, the collapse of a driveway, or even more serious damage to your home or property.

A retaining wall can provide stability to a hillside, create new and add a beautiful element to a sloping landscape. Retaining walls can surround your landscape hideaway or garden pond to give you both privacy and protection.  Most importantly, a retaining wall can take unusable, sloping hillsides and instead, create a more usable “flat space” for your outdoor area.

Retaining walls are only as good as their construction.  We adhere to the highest design practices and standards when designing and installing a retaining wall.  If a retaining wall, whether two feet or ten feet in height, stone or block, is not constructed using the proper base preparation, drainage techniques, and backfill compaction, it will shift or even collapse at some point in the future.  We are always sure to include retaining wall engineering when necessary.  Minnesota building codes require building permits on landscape retaining walls in excess of four feet tall.

Your sloped area may require an SRW (segmental retaining wall) to control erosion of a hillside or other area.  We use geogrids, net-shaped synthetic polymer-coated fibers, to reinforce the sloped area.  These geogrids provide a stabilizing force within the soil structure itself, which occurs as the soil “fill” interlocks with the grid itself.  A properly installed geogrid can support the weight of automobiles and even houses and other structures.

We understand the problems that can occur when a retaining wall is improperly designed or installed.  We do not cut corners when installing retaining walls and you can rest assured that your Premier Patio and Landscape, designed and installed, retaining wall will provide many years of safety and security.  Premier Patio and Landscape can either build stand-alone retaining walls or design and install a retaining wall as part of your next landscape design project!



Choosing Materials For Your Retaining Wall

We can build you a structurally sound retaining wall using a variety materials.  Our professional installers have much experience with both modular(block) and natural stone(boulder and other) landscape retaining walls.  They both have their advantages.  The advantages of man-made materials such as concrete blocks are lower cost for materials, uniformity in shape and superior weather-resistance.  Modular walls are extremely sturdy and lasting whether it is a pinned or weighted system.  There are many brands and styles of blocks available for building retaining walls. We work with the top  brands in the industry: VERSA-LOK , Unilock, Anchor Block, Diamond, Keystone, Timberwall and Belgard Wall Block.  Stone is the other acceptable material used for constructing landscape retaining walls.  Boulder walls are very popular for their strength and natural appearance.  Fieldstone boulders are among the most widely used, but any type of boulders will suffice.  The advantages of boulder and stone retaining walls are their weight and the fact that they will literally last forever.  The heavier the materials are, the less engineering and reinforcement is required.  One isn’t necessarily better than the other.  It really comes down to personal preference and the surrounding environment.

Materials you should avoid when constructing landscape retaining walls are landscape timbers and railroad ties.  Wooden products will rot even if treated.  They were extremely common twenty years ago, but now we are constantly replacing them with concrete blocks, boulders and stone.   Not only will timber walls rot, but they are expensive to dispose of because they are usually chemically treated and there are a limited number of disposal sites across Minnesota that will accept them.

Freestanding Walls

 Freestanding walls and accent walls are becoming more and more common in landscape design.  They help to define outdoor spaces and can add privacy to an otherwise exposed patio area.  Freestanding walls are almost always modular block or stone and are usually held together by gravity and concrete adhesive.  You want to avoid any kind of mortar in Shakopee, Minnesota and anywhere there is freezing temperatures unless you plan to install a frost footing to build on.  Mortarless modular walls and columns last the test of time proven by the great pyramids and other ancient structures.  When designing a freestanding wall you want to choose a material that is finished on both sides to avoid much unnecessary labor.  Not all retaining wall block will work for this application, but Borgert, Belgard, Versa-lok and Anchor all offer a freestanding wall unit.  There are many different styles and designs for freestanding walls.  Please contact us today and ask to see our many photos of retaining walls and freestanding walls.
