Mbrico Rooftop and Raised Floor Installation Guidelines

*The following information is the installation guidelines Mbrico recommends when installing the Mbrico Tile Rooftop or Raised Floor system. Installation guidelines are the steps Mbrico recommends to insure a successful application. Ultimately, the purchaser and the onsite installer are responsible for ensuring proper installation.

**Mbrico recommends that consumers contact a qualified installer in their area prior to placing an order to ensure all measurements, order quantities and installation are done accurately. Mbrico is a tile decking product manufacturer and tile distributor. All installations are done by a third party installer of the consumer’s choice.

Verify that your flat roof and structure have been constructed properly. Verify your project’s frame, concrete, walls, slope, grade, quality and attachment to any structure meet or exceed all local and national codes. This system is intended to require no penetration of roof membranes.

Follow the layout that was used to order your Mbrico deck surface materials if possible. Your layout will minimize the cuts and partial tile locations to less obvious areas of the surface just as you would with interior tile products. In some respects, layout of your new deck is similar to laying interior tile. You will need to plan ahead for stairways, angle areas and partial rows that require cutting tiles. Also you will plan for the fastening of your handrails if applicable or surrounding parapet walls. Nothing will be directly attached to the Mbrico surface via fastener or adhesive. The Mbrico deck should be planned and installed with greater care, as it will outlast other deck products and have no maintenance requirements other than an occasional cleaning.

You will want to set the height of your deck accordingly. The Mbrico rooftop surface adds variable height and a total weight of 10.5 pounds per square foot to your existing surface. The finished Mbrico surface is intended to be level.

Installation on raised pedestal system is used mainly on large, regular surfaces, or above previous floors, rooftops or balconies provided these show no signs of infiltration. The open gaps between the slabs allow the rainwater to drain off into the cavity created under the panels. Thus a flat, even floor is obtained, while the underlying waterproof layer will have the gradient required to drain off the rainwater. The load-bearing structure is made of polypropylene feet with a large base and rounded edges, to prevent damage to the insulating layer. This solution allows for passage of any underlying elements and offers a practical passage for pipes and wiring.

For laying on feet, the underlying base must be fully waterproofed.
Before laying clean, the underlying base carefully.
Select appropriate size and height pedestal for starting row with consideration for rooftop slope. Pedestals come in 3 sizes and are adjustable for height and slope. Extension rings are available for additional height requirements.
It is advisable to start laying from a perimeter corner, if there is one. This allows you to use complete tiles and work across the surface using the tiles as your spacers. You will notice 2 sides of the Mbrico tiles have spacing bumpers machined into the substrate. Tiles should be aligned bumper to bumper. Sides without bumpers should be aligned with tracks.
Using your surface plans, begin placing pedestals spaced according to load requirements. (See image below).
Using the rooftop flat track (for flush against perimeter), begin installing first track against perimeter structure of surface. The patented Mbrico rooftop 4-meter extrusion can be “clicked” into the click top pedestal feet. No additional fastener is required between the extrusion and pedestal.
Once tile layout is figured, use supplied epoxy adhesive to fasten tiles. Apply half-dollar size amounts every 6” to top of perimeter track.
Tiles are to be adhered to perimeter track and overlap to compensate for distance between wall and pedestal. Leave at least 1/8” gap between tile and structure.
Cross-bracing must be used to prevent surface racking from side to side. This greatly increases stabilization of the Mbrico surface. Mbrico provides 3/4" x 12' aluminum angle to be used for cross braces. They are simply used as 12' lengths, flipped upside down and installed using self tapping stainless screws to the under side of the T and Offset-L tracks as shown. See chart at bottom of instructions for cross brace spacing guidelines. The cross-bracing can be cut to length as needed to accommodate deck sizes as needed.
Begin installing tiles in first row. Grooved edge of tile is to be receiver by horizontal flange on Mbrico Tracks. Continue previous steps and begin installing tiles outward from perimeter.
For non-perimeter rows, use and Mbrico T-Track so tiles can be received on both sides of the track. This provides automatic spacing and captures the tiles.
When installing, check that the laid slabs are level, using the slope adjustable feet. Supplied shims can be used if additional slope correction is needed. Set laser and tripod on top of tile to insure level installation.
To connect tracks to one another, use a Track Connector Sleeve and included hardware. Four self-tapping screws per connector are included. The aluminum profile system connector enables the system profile to extend endlessly. The connectors are simply inserted and fixed with the matching self-tapping screws supplied in the package.
Track joints of the substructure should always take place directly over a pedestal point. To reduce vibrations, we recommend the adjustable feet every second substructure profile around L/2 offset to arrange. Refer to previous diagram.
When installing, check that the gaps between the tiles to see they run flush and even. This increases aesthetic appearance and also ensures for proper water drainage.
Continue previous steps as you install tiles across deck body surface.
When opposite perimeter is reached and final row is to be installed, tiles can be cut to size to meet dimension requirements. Tiles can be cut using a conventional wet tile saw with a diamond blade.
Use Mbrico perimeter flat track to finish final row against structure. A 1/8” gap should be left between Mbrico surface edge and any structure or wall to allow for proper drainage (see step 7).
