- What is a Mortarless Wall?
- Mortarless Walls are made up of modular units
of pressurized concrete that stack and interlock to form a very
strong wall. As the name implies, no mortar is used between
- Do I need a foundation?
- Yes, but nothing similar to a poured concrete
wall or house foundation where you would need to excavate up to 4
feet deep and between 2 and 3 feet wide and pour a concrete
foundation. Typically all we need to do is excavate a trench
18 inches wide x 6-12 inches deep depending on the height of the
wall. The "foundation" is a mix of 3/4 inch stone
down to stone dust.
- With no mortar and no concrete
foundation, is the wall strong?
- Yes, no question about it!
- The Stones are made of pressurize concrete.
- Each row steps back (batters); by the time we
get to the top many rows of blocks are actually behind the bottom
- This reduces the hydrostatic pressure
behind the wall by almost 33%
- This also causes an aesthetic
effect. Instead of having a 4 foot wall that is straight
vertically, "boxy looking", the battering of the
courses causes a feathering of the wall.
- Because each stone is not mortared, in essence
that creates numerous drainage locations during heavy rainfall.
- Behind the wall is filled with approximately 1
foot wide of gravel, causing the water to follow gravity instead
of causing pressure, which causes other type walls (timber, poured
concrete, cinder, brick) to lean or tip.
- Does my wall have to be straight?
- Absolutely not, possibilities are
endless. With the Diamond Block we can build convex
(outside) curves, concave (inside) curves and slow winding
serpentine curves. see examples
- Can I have steps integrated within
- Can I plant behind my wall?
- Yes. You can plant shrubs, trees and
grass. When reinforced you can plant vehicles behind the top
of the wall. see examples
- Do I need caps on my wall?
- Do you only build with Diamond
- No, but....We have built walls using 6 or 7
different manufacturer's blocks. Some are less expensive,
some are lighter and some have different functions. Taking
everything into concern: customers needs, ease of
installation (no pins), cost, steps, caps and application
possibilities. The Diamond Block meets more of those that
any I have used. I have no affiliation with Anchor Block
(manufacturer of Diamond Blocks) and will work within your needs.
