Cinder block retaining wall no mortar.

Dry stack concrete block cinder block technique uses surface bonding cement sbc instead of mortar for high thermal mass htm thermic walls that are waterproof and much stronger than conventionally laid mortar block walls. Expect to spend 20 36 hours building a 3x10 foot concrete block retaining wall. As the last step fill the cores around the rebar with mortar from the bottom to top. Known as half blocks these smaller blocks are used to create a running bond pattern that lends strength to.

The hollow core design combines with mortarless construction to allow water to drain freely from behind the segmental retaining wall. Terra force is an environmentally friendly cost effective and attractive alternative to other retaining wall systems. At each end of the wall set an 8 x 8 x 8 cinder block smooth side facing out. Incidental water moves easily through a vertical drain that is formed by the layer of wall rock placed behind the block and in the block cores.

No mess and no mixing required. Place the first cinder block on top of the mortar. A well built cinder block retaining wall can add a sense of a separate secure space within a wider space turn a slope into a garden and add living space by holding back a hillside. This should be done at every three blocks or at intervals specified by your local codes.

Quick wall build time. A retaining wall design service is available with a construction drawing being provided if required. Line the cinder block up right over the prepared area then gently lower it onto the mortar. Although type s mortar must have a minimum compressive strength of 1 800 psi it is often mixed for strengths between 2 300 and 3 000 psi.

The dry stack construction technique allows the incidental water to escape by flowing around the blocks and out the. No mortar required for the jointing of the wall blocks.

Type s is the common choice for many below grade applications such as masonry foundations manholes retaining walls and sewers as well as at grade projects like brick patios and walkways. Push the cinder block into the mortar very gently until it s sitting 3 8 inch 0 95 cm above the footing.
