Can I install the Stavoblock facade on my own?

Yes. If you are skilful and have the proper equipment, you can start working. The installation manual is available on our website. We are available to address any questions, or we can also provide training on the site.

How is the Stavoblock facade installed?

First, you install the load-bearing grid. Then you anchor the protection against rodents on the Omega bars to the footing of the house and insert thermal insulation, which you attach to the wall using disc shear plates. Then, it is time to start installing the Stavoblock facade bricks. Everything is described in the installation manual.

Does it mean I have to screw each brick individually?

No. When the load-bearing and spacing Omega bars and the thermal insulation are installed, you simply lay the individual rows of bricks, one on another, and the Omega bar mounts lock in the groove on the back of the brick. There are two methods of laying the bricks on the grid: facing bond, or no-bond – to cut. The individual rows of the facing can be “LOCKED” to the load-bearing Omega bar by bending the bottom mount of the Omega bar using side cutting pliers. That prevents any vertical movement of the facing. WE RECOMMEND LOCKING EVERY TENTH AND LAST ROW /end row/. When the bricks are locked, they are inserted horizontally to the Omega bar mounts. When laying bricks on the wall, alternate between various pallets to achieve better identity of colour. Check the planeness during installation using the water level. It is important that the bricks are properly laid to prevent penetration of rainwater into the facade casing. Lay the bricks so that the top part of the brick is the tongue and the bottom part of the brick is the groove.

Does each brick have the suspension grooves?

Yes, each brick has two grooves forming a V-joint on its “back”. This groove position is a typical feature of the whole Stavoblock product series.

How are the Omega spacing bars anchored?

The Omega bars are attached to the wall vertically, with axial distance of 470 mm using the adjustable angle bars. The angle bars are attached to the wall using Mungo dowels 10x100 mm with a hexagonal bolt, in horizontal spacing of 900 mm and below. The Omega bars are connected using a connecting piece and two M6x12 bolts with flanged nuts. Gently tighten the bolts and use force to pull the bars apart. Then, tighten the bolt nuts to the end. That will provide a constant distance between bars, which should be 4 mm. The adjustable angle bars are used for levelling the load-bearing grid vertically and horizontally and they provide a sufficient stability of the spacing grid. Their dimensions are determined by the thickness of the used insulation and the requirement for offsetting the Stavoblock facade from the wall.

Can I also use wooden spacing bars?

No. Never use wooden spacing bars for the installation of Stavoblock facade.

What to do when one of the bricks in the facade gets damaged?

The bricks can be replaced without the need of disassembling the neighbouring bricks. Carefully cut out the damaged brick, e.g. using a sharp blade. Collect all fragments of the broken brick from the spot to be repaired. Then, take a new brick, lightly lift the top row of bricks and insert the new brick to the original spot. If the brick is locked, you pliers to bend the bottom mount on the Omega bar towards the wall so that you can suspend the brick on the top mounts. Sometimes, it is better to replace the damaged brick from the closest corner. Carefully disassemble the corner brick in the row of the damaged brick and then insert the side tiling to the missing spot and add the remaining bricks.

Do any small parts of the material loosen from the brick surface?

Yes. This can happen in all products with split surface treatment of the facing. When splitting products, the individual grains on the level of the product crack (split) at the facing due to the splitting knives. The loosened particles and grains then remain trapped between the two facings of the product. During installation and after installation, the surface of the product may seem to be crumbling and dusty. This is not a product defect; they are just loosened particles after the splitting process. Atmospheric effects on the facade (rain, wind) remove the particles from the surface of the bricks.

What is the maintenance of the facade, does it have to be painted?

No, you never ever need to paint your facade again. If required, you can wash it with water.

Can I use combined bolts for anchoring the bars?

Yes, you can. The combined M6 x 80 bolts are used for “tight” wall cladding when the distance between the rear face of the Stavoblock brick and the wall is only 10 to 40mm. To level and set the bars, simply use thin M6 nuts.

Can I use Stavoblock bricks in the interior?

Yes, you definitely can. Follow the installation manual, or use dry-bond building adhesive to attach the tiling.

How much is a square meter of Stavoblock?

We need more information about the project to be able to answer this question. To provide correct information, we offer free consulting services, including the preparation of a quotation, directly on the site, a statistical calculation or preparation of project documentation.

What are the advantages of Stavoblock when compared with other systems?

Stavoblock is definitely advantageous thanks to the fact that it is not required to brick up foundation. The wall is built on a packed aggregate bed (about 150 to  200 mm thick – according to the wall thickness) and the individual blocks are then assembled in a dry manner without any concreting and reinforcing. There is no pouring of concrete and technological breaks. Dry assembly constructions allow relative displacement between the  individual bricks caused by uneven settling, different load and other effects.

Dry joints eliminate ugly cracks in the bed and butt joints and braces that prevent movement of the wall. The variability of the system is also an important aspect, as well as its visual effect where it is possible to combine shapes, surfaces and colours.

How high can the wall be built?

Stavoblock is suitable for the construction of dividing walls and supporting walls, almost without any height limitations (static evaluation is required for heights above 1 m).

Can I use Stavoblock to build a fence?

Yes. Basically, two facing elements are assembled together. They are connected using anchoring connections (the selection of which depends on the thickness of the wall). It is possible to build a fence wall that is split with sand colour on one side and red-brown ground on the other side. The system also provides other elements for solving corners and finishing covering boards.

What is it like with fence filling and the gate?

You can install both filling and a gate or a large gate for a vehicle into the dividing walls, as well as electric distributors. We recommend consulting the method of anchoring and installation with a technical consultant, or you can find the information you need in the recommended installation manual.

How do I finish a supporting wall?

You can finish the supporting wall with covering boards or by levelling the terrain up to the height of the supporting wall. If you use the covering board to finish the supporting wall that will be walkable (terrace), we recommend using adhesive for concrete to install the board.

How many anchoring braces do I need to use behind the facing element?

The number of anchoring braces is calculated statistically based on the load. You can find construction drawings of supporting walls on our website, sorted by height and load based on the statistical calculation.

Is it possible to use Stavoblock to build the supporting wall and then do the backfill?

No. Each layer of the Stavoblock masonry must be backfilled with the filling material. The material is compacted, overflowing material is removed, bricks are swept on the top and then you can start building a new layer. Compaction of the reinforced soil or soil behind the wall is also done by individual layers.

What material to use for backfilling a Stavoblock supporting wall and for foundation?

To backfill Stavoblock bricks, you should use sorted and washed aggregate with appropriate grain composition. The ideal backfill material is aggregate /gravel/ with fraction 4-8 or 8-16 mm. For the foundation, you can use aggregate with a larger fraction /16-32 mm/, or the same aggregate as for the backfill. It is important to create a levelling layer from fine aggregate into which Stavoblock bricks will be installed.

Can I use Stavoblock for outdoor staircase?

Yes. You can use the facing element with a combination of anchoring braces to build the staircase and the covering boards as the contact layer. The system can be used to build an open, closed or arched staircase.

What are the advantages of a staircase built from Stavoblock?

Stavoblock has a great advantage in not having to brick up the foundation. The wall is built on a packed aggregate bed (about  50 to 200 mm thick – according to the wall thickness) and the individual blocks are then assembled in a dry manner without any concreting and reinforcing. There is no pouring of concrete and technological breaks. Dry assembly constructions allow relative displacement between the individual bricks caused by uneven settling, different load and other effects. Dry joints eliminate ugly cracks in the bed and butt joints and braces that prevent movement of the wall.

Another advantage is the better static bonding of the facing elements using connections and braces that prevent movement of the wall. The variability of the system is also an important aspect, as well as its visual effect where it is possible to combine shapes, surfaces and colours.

Is it necessary to always build a staircase as a part of the supporting wall?

No. The staircase can also be built as a solitaire in the garden with adding a railing, which depends on the owner of the construction.

What is the height of the stair?

The stair is 200 mm high. Standardly, it is formed by the Jumbo element (200 mm) and the covering board (75 mm). The covering board for each stair always covers the part of the facing area of the Jumbo block. The facing area of the stair is thus 125 mm.  

How much is a square meter of the Tri-Lock pavement?

To calculate the price per square meter, we need to know what purpose the pavement is to serve, what terrain it is going to be installed in and what the load will be. Then we can recommend a suitable thickness, reinforcement or surface treatment.

What is Tri-Lock made from?

The pavement is made from high-strength precast concrete and it consists of two parts: the lock and the key. The elements of the system are manufactured in two dimensions and weights for maximum protection of the foundation and for various loads.

What are the advantages of Tri-Lock when compared with other systems?

A regular interlocking pavement is not only more demanding when it comes to the base material, preparation of the bottom layer and duration of the installation, but it also often requires securing the side edges of the pavement with curbs to prevent gaps between the individual pieces. We need to emphasize that such types of pavements are impermeable, without the ability to absorb water after rain. Any slight irregularities of the surface of the pavement creates puddles. When you use Tri-Lock, you don’t need to install curbs along the edges of the pavement and the shape of the pavement prevents the creation of puddles.

How is Tri-Lock assembled?

The individual blocks are standardly assembled manually. For roads, the base is prepared in the same way as for an interlocking pavement but curbs are not required to be used with Tri-Lock. The system is easy and it can be installed by untrained workers supervised by a trained employee. The pavement is maintenance-free for its entire service life.  

Can I also use Tri-Lock as a porous pavement?

Yes, you can use the pavement to reinforce areas that will be turfed later. The system is suitable for parking lots, temporary roads and park pavements. It is safe for lawnmowers.

What are the main rules for installing outdoor pavement?

The installation of outdoor pavement must follow several important rules. The pavement must have a falling gradient to prevent the formation of puddles and to allow water that is not absorbed to flow away. When the terrain is sloping, you should choose a rougher surface of the pavement for safer walking. Place the pavement on a permeable, properly pointed base layer of fine chippings (5 cm) placed on a rougher gravel layer (10-15 cm). Use dry quartz sand (0-2 cm) to fill in the joints and let it sit for about three weeks to settle before you sweep the pavement.

What is the load capacity of the interlocking pavement?

If you choose an industrial interlocking pavement, the load capacity is really high. The joint concrete pavement is able to withstand the load of freight traffic of up to 40 tonnes.

What terrain is Tri-Lock suitable for?

Tri-Lock is ideal as reinforcement of areas surrounding buildings, water channels and lake dams. It is ideal for sloping or statically or dynamically exposed areas and slopes that are exposed to erosion. It can be used as permanent concrete mesh installed below the surface of the terrain and so on. Flexibility is achieved by bevelling the internal lock of the blocks that allows using the system in an undulated terrain. It can also be wrapped in the plane and twisted into a helix. It can be applied on slopes of up to 60°. It can also be installed under water.
