A retaining wall can sometimes be simply a functional and necessary way to remedy a steep slope in your client’s landscape, but other times it can serve to add some much needed dimension and interest. While natural stones are quite beautiful, they can also add cost to a project because they are heavier to transport and require a lengthier construction time. Unilock wall units have all of the charm and appeal of natural stones, but they can significantly shorten the installation time for a York, PA, retaining wall project.
