Retaining and Boundary Walls

Blockwork

In the construction of a retaining wall there are a variety of strength options depending on the load of the wall.  The most common is of a 9 inch hollow section block which is then later filled with a 4 in 1 or C25 strength concrete mix.  This can then be faced with brick if desired. Another Option for a less load bearing wall is a 4 inch solid block which is then faced with a 4 inch brick

Boundary Wall

This is largely down to personal preference.  It can be either a concrete block or brick built wall
