London Boulder

48” Full Block

48” x 18” x 42” (32”)
Weight: 2160 lbs
Sq. Ft./ Block: 6 sq. ft.

The 48″ Full Boulder will make up the majority of most walls. The primary characteristics of the Full Boulder are its 48″ front face tapering back to a 32″ rear face, with two parallel channels on the top surface and two interlocking box lugs on the bottom surface.

The tapered block is a benefit when building curved walls as it allows the turning of a radius in shorter distances and with no cutting. If your radius is extremely tight, simply knock off the necessary box lugs and rely on the ball lug to keep the two units interlocked.

The 1/2 Corner has all the same features as the Full Corner with the exception of its front and rear faces being 24″ and 16″ long, respectively.

When building a retaining wall, this is the perfect unit to begin your second course since it allows for a half-stagger of the vertical joints. Likewise, it is a great finish to the end of your wall.

Whatever the type of wall, the Cap Boulder is the perfect unit to finish the top course. With a front face that is identical to that of the Full Boulder, the Cap Boulder maintains continuity on the front side of the wall.

However, the back side of the boulder is recessed 8 inches to allow for the application of soil, sod, rock, mulch or any other fill material the end user deems necessary. The Cap Boulder¹s sides are tapered to allow for a radius wall if desired.
