The special mixture of mortars adds to our Solid Bricks properties such as greater resistance to thermal changes, to acidity and to salinity.Furthermore, Roka Refractories’ concrete bricks present notable resistance to humidity since their water absorption rate is very low. Concurrently, they present notable compressive strength (43,5 MPa).As a result, our concrete bricks remain unaffected by both time and weather conditions.Applications of humidity resistant bricksHumidity resistant bricks are applied mostly for the construction/decoration of public buildings and private in order to prevent humidity from entering causing this way. Those bricks could be found mostly in the following categories of buildings:Administration BuildingsUniversities/Schools
Accommodation CentersUnderstanding the effects of humidityPreventing humidity level to be balanced is essential to improving indoor air quality and the overall health for the substitutes living/working at the building. To ensure air quality, the Environmental Protection Agency (EPA) suggests maintaining proper.Roka Refractories indoor relative humidity (RH) levels to reduce the effects of many of unwanted conditions associated with poor indoor air quality.Effects of high/low humidity levels to individuals.Too much humidity can cause an increase in biological pollutants, like
Those pollutants through dust can trigger respiratory health ailments.
Too little humidity can lead to nosebleeds, painful skin irritation, difficulty breathing and damaging static electricity.Best for DesignThanks to the innovation of Roka Refractories R&D department, our products can meet most of the architect’s demands by giving the most outstanding result not only in refractoriness and humidity insulation but in design as well since that they are available to the following colors:Colors:Still de Grain Yellow

Application of bricks to wall
Step 1: Prepare Wall for Tile
Make sure the wall is smooth and clean. Dust and debris will make it more difficult for the glue to properly bond. Then, use a level and a straight piece of wood to create a temporary “ledger” across the bottom of the wall. The ledger is a guide that will allow you to keep the bricks straight and level as you tile. When you’re finished, the ledger will be removed.
Step 2: Cut Bricks
Start by cutting several thin bricks in half using a tile “wet” saw or a diamond blade grinder. Doing this prior to installation will save time during the process so you’re not continuously stopping to cut more bricks.
Step 3: Install Corner Bricks
Start your installation at the bottom corner of the wall. Use a notched trowel to spread mastic over a small section of the wall Next, press a full brick to the outer edge of the lower corner of the wall. Continue upward with a half cut thin brick with the same application technique: full brick, half brick, full brick, half brick,
This creates the start of your “running bond” pattern, which is the most common layout of real brick masonry partitions.
Step 4: Install Full Rows
Continue this technique about halfway up the wall to start. Then, go back down to the bottom of the wall and start running the full bricks to complete the first row, or “course.” Work your way up the wall, row by row.
Step 5: Make Sure Rows are Level
Check that the courses are running straight by using a 4-foot level. You have about 20 minutes to adjust the veneer bricks before the adhesive begins to set.
Step 6: Leave Space for Grout
Create grout joints of 3/8” to 1/2” wide between bricks and between upper and lower rows, as well (Image 1). Measuring by eye is encouraged to give a more authentic look. Alternatively, you can rip down some scrap wood on a table saw into 3/8” strips to make grout spacers (Image 2).
Step 7: Install Remaining Bricks
Once you’ve reached the halfway point, continue with the corner bricks the same way as Step 2. You may finish the remainder of the wall to the ceiling height. Continue the laying of full bricks to complete the remaining rows. Stand back from the wall every so often to “size up” the job and to check for even running courses.
Step 8: Apply Grout
Allow brick to dry for at least 24 to 48 hours. Then grout in between joints using Portland cement mixture squeezed through a grout bag and apply to joints in small areas at a time.
Application of bricks to floor
Brick flooring can provide you with a beautiful look for both internal and external. You can also install it outside for a nice touch to your patio. If you are going to install brick flooring, you want to make sure that you understand how to do the job properly. Here are the basics of how to install brick flooring.
Step 1: Determine How Much You Need
First, you’ll want to measure the area in which you are going to install the brick flooring. Take your tape measure and get the length and the width of the area. Multiply the two numbers together to get the exact square footage of the room. Then you will want to add approximately 10 percent to that number so that you will have enough for waste.
Step 2: Plan the Layout.
The next thing that you will want to do is plan the layout. There are several different patterns that you could do with your brick flooring. You could utilize a straight lay, a brick pattern, or a herringbone pattern among others. It will usually be to your advantage to draw out a diagram so that you can see how the flooring will lay out when you are done. Spend some time planning so that you can get a good picture of what you want to accomplish.
Step 3: Prepare the Floor.
You will need a solid subfloor to attach the brick flooring to. If you have a concrete subfloor, you can attach it directly to that. If you are dealing with a wood subfloor, you are going to need to put some concrete board down on top of it. Put some adhesive on the bottom side of the concrete board and then nail it down to the wood subfloor.
Step 4: Determine Starting Point.
You will then want to determine where you are going to start laying the brick flooring. In many cases, you will want to center the brick flooring in the room. You can do this by measuring the center point of each wall and snapping a chalk line in both directions. This will divide the room into four quadrants and then you can focus on one at a time.
Step 5: Lay the Brick Flooring.
At this point, you can start laying the brick flooring. You should be able to apply some of the adhesive to the floor with your trowel. Make sure to smooth the adhesive out with your trowel. Then press a brick down into the adhesive firmly. Press another brick down directly next to the first brick according to your pattern.
Step 6: Making Cuts
When you get to the edge of the space, you are going to need to make cuts in the appropriate dimension. Measure the size of brick flooring that you need and then use your wet saw or a grinder to cut the piece that you need.
Step 7: Finishing Up
Once you have the brick flooring laid, you will want to allow the adhesive to dry overnight before walking on the floor.
