The use of a gravel base is the most economical and straightforward approach to building a stone wall. Gravel Masonry can be used for anything from retaining walls to garden borders, and is a great alternative to standard brick work or concrete block masonry.
The best gravel for a stone wall is a fine, washed, crushed aggregate. This type of gravel is typically produced by crushing granite, gneiss, limestone or trap rock and then washed through screens to make sure the resulting granules are consistent in size. The best gravel to build a stone wall is also free from sand, silt and clay. This ensures that the stones will adhere to the mortar and the mortar will not loosen over time.
It is important to start with the largest possible rocks to build your wall with. This will help reduce the number of smaller pieces needed to fill the voids in the wall and increase the strength of the structure. Also, starting with a level base will help to minimize the number of steps in your finished wall.
The first course of the stone wall should be built tightly and securely to support the weight of the wall above it. This is particularly important in windy areas.
After the foundation course of stones is laid a coarse gravel is packed in between the courses for stability. This can be either a decomposed granite or pea gravel, and should be free from any large clumps of sand or clay.
Generally, the height of gravel masonry walls is limited to 3 feet. If a higher wall is desired then an engineered system should be considered. The construction of a dry-stack stone wall requires a very high degree of accuracy in the placement of stones. A string line, stakes and a level will all be very useful in keeping your wall straight.
Stones should be sorted and graded to ensure that they are free of large cracks or imperfections. In general, good stone has at least one longer dimension (cubes and spheres are difficult to build with) and should be flat or blocky in shape rather than rounded. If a more refined look is desired the use of smaller stones with a more defined face will achieve this.
Once the stone is prepared it is important to plan out your course layout. One of the primary reasons that stone walls fail is due to a lack of proper planning. It is imperative that you set each stone so that its long edge goes into the wall. This increases the friction between stones and helps keep them from moving independently of each other.
A good mason will use a concrete sand for mortar, which is usually a mixture of sand and varying sizes of aggregate, but can be any type of quality sand. In addition, mason sand is washed to ensure that the granules are consistent in size and free of clay and silt.
