Werkhof Blocks Benefits

Use Werkhof Blocks to build high quality and durable walls - faster than CHB!

Cooler Rooms

Heat always travels from hot to cold.  Werkhof Block slots are not filled with mortar.  Only the single rebar core hole is filled with mortar.  The "air gap" of two or three rows of slots within the masonry wall reduces conduction.  The air cells allow convection, this helps dissipate the heat within the outer layers thus insulating the inner wall surface from exterior wall face heat.  Cool rooms faster and save energy.  Stay in your cooler home with Werkhof walls and stay safe.  No need to go to the mall to cool off.

Build like "LEGO"

Doors and  window openings are easy - no formwork is required.  Using our precast Post Blocks, U-blocks, Transom bars and Lintels these accessories are stacked on the blocks over the openings eliminating the need of formwork and waiting for lintels to cure. Header walls can then be completed on the same day.  Much faster construction.

Easy piping and No cracks

Our blocks are very High Density and do not easily chip or crumble, but because of the unfilled slots, it is easy to cut into the wall for embedding of pipes, switch boxes, power outlets, plumbing, etc. Just cut into the outer wafer of the Werkhof block with a diamond cutting wheel or pipe chaser and strike with a hammer to make a groove.  JUST ONE HAMMER STIKE to open a groove.  No more inefficient chipping with concrete nails or chisels.  Some masonry claim to have 'workability like wood',  but is still very time consuming to chip away grooves.  With some softer blocks, chipping actually causes cracks on the mortar joints.  Werkhof is the fastest wall to make grooves for embedment.

And by cutting out the outer wafer to access the first slot, piping groove depth is consistent at 40mm.  Therefore, pipes are always adequately imbedded to the correct depth allowing for correct patch thickness.  This eliminates patch cracking and paint failure over incorrectly imbedded piping.

No Plaster = No Cracks, no peel off, less material, cleaner jobsite, faster to complete = LESS COST

After the wall is piled, the pipes and switches have been embedded, the doors and window openings have been cut straight.  All the damage have been patched and bulges have been ground to within 3mm flatness.  Simply apply 2mm to 5mm thick render skimcoat and paint.  The blocks are pre-cured and of high density, the render remains thin and will have good adhesion.

Accurate and Straight Windows - much faster and cheaper than AAC

How long does it take your mason to finish a door or window opening?  CHB, AAC or any other softer masonry carcass' needs a solid concrete edge patched or plastered around the opening for attaching windows and doors.  Not Werkhof, openings are merely cut straight to the final opening dimension.  No need to plaster for solid edge frames.   

Just use Frame Bolts or Concrete Screws to directly install doors, windows, TV's, cabinets, etc. to our high density blocks.  This means higher quality and stronger window anchorage and very durable door  attachment.  Hard homogenous edge also means less edge chipping and no dry patch or cold joint cracking.  Up to 10 window openings done by one laborer a day, much lower labor cost and faster than a mason + helper to plaster edge one window per day!

5X faster than CHB

Werkhof blocks have profiled tongue and groove ends for quicker end to end alignment resulting in straighter walls.  Thin bed tile adhesive between rows allows for straighter stacks and quicker tack times unlike thick mortar that you need to allow to dry and set before you can pile on more rows of blocks.  Only one rebar core to fill, so very little mortar is used.  Therefore, much less material, much less labor and a cleaner Job site.  

 

Straight and Flat walls with sharp and accurate corners and edges are also faster to finish and paint.  Less time is spent on repairing the surface, crooked corners and chipped edges.  Therefore, added savings on painting and finishing costs.

No joint cracks and leaks

Werkhof Blocks have profiled vertical end joints that 'lock' the individual bricks to form a contiguous wall.  1mm tolerances at the joint nest stops any capillary migration from the outside wall surface to reach the internal half of the wall.  Once exterior render and paint finish is applied the joints are 100% sealed.  Thus highly leak resistant.  This locked joint also greatly strengthens the joint against seismic or building settlement movements that are the main cause of cracks and leaks.

Secure tile adhesion, no damaged tiles

Werkhof walls are high density hard walls, therefore the best substrate for tiles.  Install your tiles directly on Werkhof, no need for render or plaster as the werkhof wall will not leak.  Stronger bonding of tiles direct to the block and not to the plaster or skimcoat means no cracking or delaminating of your expensive tile.  Build stronger, build faster, better quality finish. 

 

Unlike AAC that is low density, porous and absorbent, Werkhof walls do not require solid concrete 'zocallo' in the bathrooms.  This is a cost and step in the work of bathroom walls that is eliminated.

Customer Service

German technology and efficiency at work for you. Our engineers have worked out not only how to make the blocks but how to build your wall.  Our work does not stop at our door, we invest in tools like stone splitters, stone cutters and shipping pallets to service our customers to make your project more organized and manageable. 

We provide hands on and on-site training on the best practices to build your Werkhof walls safely, clean, plumb, straight, flat and strong so that you optimize the benefits of using the Werkhof System.   Our team is on call to orient new workers as they are hired and also do servicing of the stone cutting tools that we provide for free.

 

Our Staff will also continue to visit the Project at least once a week until it is completed to ensure that your masonry crew is applying the correct procedure and that they are using the correct tools to make sure that the wall is built correctly. 

We don’t just sell blocks, We teach how to build good walls!  We partner with you to efficiently build high quality and durable  structures using our Werkhof Blocks.
