Regardless of the type of ground cover you choose, it should always be installed with a minimum slope of 2.5%. In addition, the slope of the improved subsoil should be identical to that of the finished ground. Water drainage should also be planned. There could be nuances of tones due to the use of natural materials. We advise that all products be gathered before starting the job and that the materials from different pallets be mixed at the time of installation. In order for claims regarding the appearance or other aspects to be admissible, they must be made prior to installation, given that our liability is limited solely to the replacement of defective products, and any other expense for removal and new installation is excluded. The use of acidic products or the derivatives thereof is strictly prohibited, as well as salts used for de-icing or other products that might deteriorate the cement and cause irreparable damage. CLARIFICATION This ‘installation advice’ for paving tiles and pavements is adapted to ordinary application within the framework of private spaces. In all other cases, we refer to the current guidelines for use and installation.
1. PREPARATION OF THE WORK AND TERRAIN. PREVIOUSLY LAY OUT THE PROJECT ON A CONTOUR MAP WITH ELEVATIONS AND SURFACE AREAS
Transfer the dimensions from the drawing to the terrain using stakes and lines. Leave the desired level of the finished ground well defined.
To facilitate installation, mark the ends of the installation area using stakes, and tie cord between them. You will thus have a guide for defining the surface area of the floor. Prepare the base be excavating down to a depth of 10-12 cm.
Put down a layer of gravel. Smooth and compact it. The gravel layer should be about 8 cm below the final grade so that it can be evened out with a thin layer of mortar.
2. INSTALLATION OF ECOPIEDRA GREEN PAVEMENTS. OVERVIEW
The sand that is used must be ‘washed’ (river or other sand).
Regardless of the nature of the installation bed, it must have drainage to prevent accumulations of water on the bottom plane of the paving tiles.
2.1. Installation on a sand bed.
Spread the installation bed over the well-compacted base: a 4-5 cm layer of river sand, which must be levelled using a straightedge set on levelling shims. Next lay the paving tiles, checking that each one is level. Even out using a dowel or rubber mallet (avoid black coloured mallets, which tend to leave marks on the paving tiles).
2.2. Installation on a mortar layer.
When preparing the mortar, we advise 6 parts sand to 1 part cement. The mortar should be wet enough to work with yet prevent the tiles from being stained, which will occur if the mortar is too wet. Prepare enough for a half hour’s work.
2.3. Installation on gravel.
Regarding this technique, the installation bed should have a thickness of approximately 5 cm and a maximum grading of 15 mm.
All other application conditions are identical to the preceding ones.
2.4. Installation with glue (only on a solid base of concrete).
Installation with glue can only be done on a completely dry base (drying time of about 2 months), which must be clean and dust free. The selected mortar glue must necessarily be ECOCEMENT NATURA.
Spread the mortar glue on the base using a smoothing plane or a float, and distribute using a trowel with 20-mm teeth. The paving tiles must always be laid by double-gluing: coating the back side of the paving tiles with mortar glue using the non-toothed edge of the trowel. Then apply the grooves of the glue. Work cleanly: as the work advances, clean all remains of mortar glue from the surface of the paving tiles, because any such remains are hard to remove once dry.
3.1. If the paving is going to support the weight of vehicles (access to a garage, etc.), it is advisable to pour a layer of concrete that is approximately 10-15 cm thick. To correctly tamp the paving tiles to the right level, lay them and adjust them using a straightedge and a mallet. Repeat this process with each row. Leave a 1-cm joint between the tiles.
3.2. Depending on the manufacturing date and the natural materials used, there could be differences in the shades of our products. Therefore, it is advisable to gather all the materials together in the work zone before starting the job, and the materials from different pallets should be mixed at the time of installation.
3.3. Moreover, there could be some dimension variations inherent in the intended rustic look of our products. Such variations may not be the object of any claim or litigation, to the extent that they are within the tolerance margin that is generally accepted for this type of product.
Leave a 1-cm joint between the tiles. To seal the joints, use ECOCEMENT NATURA mortar for grouting, a product that allows the joints to be filled using a grout bag, after which the grouting is compacted using a jointer so that the joints are well sealed. This type of joint is permeable, so it is important to have provided for a good drainage system in the pavement. Subsequently, we advise using ECOCEMENT NATURA waterproofing to waterproof the pavement and the joints. Avoid sealing the joints on rainy days or when the pavement is wet.
5. FINAL CLEANING OF THE PROJECT
Final cleaning of the pavement must be done carefully:
• Never use products that are acidic (hydrochloric acid or others).
• Do not use a high-pressure cleaner.
