Abitasistema: guaranteed procedure

Abitasistema
guaranteed procedure

ABITASISTEMA® is the only guaranteed method for laying Murogeopietra stone veneer on an ETAG 004-certified exterior wall thermal insulation system using EPS, rockwool and cork panels.

Installation tips specific to ABITASISTEMA®.
The materials and methods used in the external thermal insulation system must comply with ETAG 004 certification requirements.

The adhesion surface area of the insulation panel to the wall must exceed 60% of the panel surface area itself. The consolidated layer of reinforcement plaster, created by the insulation panel, must not be subjected to primers or finishing treatments before applying Murogeopietra.
The procedure must be performed by qualified personnel in accordance with the rules of manufacture and following the technical guidelines detailed in the Geopietra installation manual.

The insulation system must be fixed mechanically using special studs for thermal insulation systems, featuring the GEOPIETRA TOP FIX screw-on system. The studs should be of a suitable length, according to the insulation thickness, and should have at least 25mm expansion clearance inside the masonry, depending on the backing.
The anchoring studs must pass through the consolidated layer of reinforcement plaster and the GEORETE mesh substrate embedded in the still fresh layer of GEOCOLL adhesive. ABISISTEMA® should be fixed mechanically by the fitter of the GEOPIETRA stone veneer.

MECHANICAL FIXING

Anchoring holes for fixing the Abitasistema® mechanical fixing are drilled in the properly set reinforced smoothing layer of the ETAG 004-certified thermal insulation. The studs are positioned according to a 40x40cm lattice layout, corresponding to 6.37 studs per square metre. In the perimeter areas (200cm from the building corner), there must be 12.49 studs per square metre. This data is indicative and must be verified according to the 1991-1 standard.

01.Stud installation procedure

 

02. Drilling and milling

Use an 8mm bit drill to make holes of at least 10mm depth in addition to the anchoring depth. Clean the holes thoroughly.
Countersink the hole to obtain a 16-18mm diameter flare to allow for flush screwing of the stud plate.

03. First masonry smoothing using geocoll

Use a smooth knife to apply a 2mm layer of soft GEOCOLL adhesive to the backing.

04. Marking the holes

Although the milled holes are covered with adhesive, they remain visible because they form a small bubble that can be highlighted by perforating it with a tip prior to the application of the Georete mesh substrate.

05. Laying the georete mesh substrate

Bury the GEORETE large fiberglass mesh by overlapping the joints by at least 10cm.

06. Inserting geopietra top fix studs

Immediately insert the Geopietra Top Mix studs by hand into the pre-drilled holes.

07. Screwing in and sealing the studs

Use a screwdriver to screw in flush with the surface top. Any studs that do not adhere should be removed or replaced. Insert the closing plugs provided with the Geopietra Top Fix studs.

08. Surface finish

Apply an even layer of Geocoll adhesive to cover the mesh and stud heads completely. Especially when the cladding is installed “dry”, i.e. the joints are not filled with mortar, make sure the stud heads are fully buried in the smoothing adhesive and add extra GEOCOLL, if necessary.
When the adhesive has properly set, the wall is ready for the installation of the stone veneer.

HOW TO INSTALL THE MUROGEOPIETRA INTEGRATED SYSTEM

Install Murogeopietra only after completion of the installation of the laying insulation system to prevent dirtying the cladding. GEOPIETRA stone veneer must be laid not before 5-7 days from the date of installation of the insulation panels.

The structural expansion joints that are already sealed should be left free.

Care should be taken to properly install Murogeopietra, in accordance with the manufacturer’s technical guidelines set out in the GEOPIETRA installation manual (accompanying each supply or downloadable from www.geopietra.it )
