Wall Block Installation

Building a Comfort Block wall couldn’t be easier. Once the base course is laid, simply stack and glue the blocks with masonry adhesive. Our blocks are ground to precise dimensions so they remain level.


The simplicity of the Comfort Block system makes masonry construction accessible to builders, landscapers, and even DIY homeowners with no prior masonry experience. There is no mortar to mix, and cleanup is virtually eliminated at the end of the day.

Just Glue and Stack!

Step-By-Step Guide


Before construction of the Comfort Block wall, ensure that all wall dimensions conform to the block dimensions to reduce gapping and cutting.


All steel reinforcement should be located according to engineering recommendations before the base course is constructed.


The preparation of the base course is the most critical stage of building with the Comfort Block System.


Before beginning construction, all coursing requirements should be considered. Comfort Block units should be used as the base course blocks. When laying the first course, standard mortar may be used to overcome any excessive variation in foundation levels. This should be used between the foundation and the first course of Comfort Block units.


Block layers must ensure that the base course is level horizontally along the length and width of each block and that there are no steps between each block. Once the block layers have the base course leveled, the highly engineered blocks combined with good craftsmanship will ensure that the walls are plumb and maintain a consistently even height.


Mortar adhesive is used to construct the Comfort Block wall system.


Due to the precision of the Comfort Block wall system, the wall remains level during the entire construction, so all that is needed is adhesive to glue the blocks together.


A special adhesive specifically developed for gluing masonry products together is available from Comfort Block.


Once the base course has been prepared, laying Comfort Block units is a simple process.


Apply at least two beads of adhesive on top of each Comfort Block unit, on the outermost and innermost walls of the block. Additional beads may be used in the middle of the block if desired, but a minimum of two beads is required.


Apply enough adhesive to cover several blocks at one time. There is adequate time to work with the adhesive (5 minutes or so), and this will speed up the laying of the blocks.


Lay the blocks next to each other using the interlocking design. The accuracy of the Comfort Block units combined with the correct standards of workmanship ensures that the walls are vertically level. Where string lines are used, they are for range only. The Comfort Block system incorporates a place to insert line pins for such a purpose.


Mechanical cutting is recommended when cutting Comfort Block units.


Use water-suppressed disk cutters, chop saws, or appropriate bench cutting saws.


Grouting the Comfort Block wall should be done when the wall is no higher than 7 courses.
Please note that some Comfort Block systems are designed to be built higher before grouting is needed.
Horizontal grouting may also be done as required.


Steel may be laid into the lowered web locations to ensure that grout covers the steel properly.


Corners must be cut to ensure that the steel intersects with the vertical grout.


It is recommended that concrete sand be used for grout, as it flows better and has additional strength. However, mortar sand may be used if that is what is available on the job site.


The Comfort Block wall system MUST have a finish on the outside to ensure that the wall remains weather and air tight.


Examples of finishes are cement stucco, architectural finishes such as Parex, and cement- or gypsum-based plaster finishes for the interior.


Thin stone veneer and external insulation systems are also an option.
