BARA-RT is a T shaped connector profile for balcony and terrace coverings. It can be used in conjunction with loose gravel, stilted constructions, or in bonded assemblies.
In installations with self-supporting pavers on screed contact points or gravel/crushed stone beds, the trapezoid perforated anchoring leg of BARA-RT is placed at the edge of the construction on top of the drainage membrane TROBA or TROBA-PLUS, where it is aligned vertically and horizontally. The vertical finishing leg provides a neat finishing edge for the complete assembly and allows for the drainage of water. The different profile heights from 9 to 65 mm accommodate a variety of edge formats. The profile can also be used in conjunction with tile coverings. In this case, the trapezoid perforated anchoring leg of the finishing profile BARA-RT is fully embedded in the tile adhesive and integrated into the bonded waterproofing assembly.
Alternatively, the trapezoid perforated anchoring leg of BARA-RT can be fully embedded in the screed, which allows for installing the mortar bed flush with the upper edge of the profile. TROBA-PLUS must be installed as an area drainage membrane between the waterproofing layer and the screed to ensure that water cannot accumulate in the screed layer. If DITRA 25 is to be installed, the screed must be 3 mm lower than the upper profile edge. The profile creates a neat edge finish and covers the edge of tiles as well as any exposed screed.
Material
Schlüter BARA-RT is available in colour coated aluminium.
Material properties and areas of application:
BARA-RT is made of colour coated aluminium. The coating of the aluminium profile is colour stable as well as UV- and weather resistant. Visible surfaces should be protected against abrasion. The tile adhesive layer into which BARA-RT is embedded may not accumulate any water (full embedding), since alkaline water has a corrosive effect on aluminium.
In special cases, the suitability of BARA-RT must be verified based on the anticipated chemical and mechanical stresses.
Installation
Installation with self-supporting pavers on mortar contact points or gravel/crushed stone beds
- Select BARA-RT according to the thickness of the edge area to be covered. Pre-formed corners are available for external corners. A distance of approx. 5 mm should be left between profile ends, with the gap covered by clip-on connectors.
- Embed the trapezoid perforated anchoring leg of the angled edging profile BARA-RT in a contact point of thin screed on top of the previously installed drainage membrane, TROBA-PLUS, and align it horizontally and vertically. When installing over gravel, the TROBA drainage mat is installed first, followed by BARA-RT in the screed.
- When using BARA-RT as a gravel retaining edge, the gravel should reach just below the upper edge of the vertical profile leg, depending on the thickness of the covering. Now the concrete pavers are loosely installed on the levelled gravel bed.
- When installing on top of TROBA-PLUS with thin bed moulding rings, TROBA-STELZ-DR, the BARA-RT finishing profile will cover the exposed edge of the assembly. The outside thin bed contact points are positioned on the trapezoid perforated anchoring leg of BARA-RT.
- The self supporting pavers are then laid onto the contact points. When using the stilted construction with TROBA-STELZ-MR, the profile BARA-RT is integrated into the mortar point. The finishing profile covers the exposed edge of the cover assembly. The self supporting pavers are then installed on top of the stilted construction.
Note: A sufficiently large space for drainage must be provided to allow for unobstructed water drainage in the edge area of the cover assembly.
Installation in conjunction with tile coverings
- Select BARA-RT according to the thickness of the edge area to be covered. Pre-formed corners are available for external corners. A distance of approx. 5 mm should be left between profile ends, with the gap covered by clip-on connectors.
- Embed the trapezoid perforated anchoring leg of the edging profile BARA-RT on the edge of the screed or on the previously installed drainage mat DITRA-DRAIN by placing it into the contact layer of thin set adhesive and trowel additional adhesive over the leg so that it is completely covered.
- If using DITRA 25, abut the edge of the membrane to the anchoring leg. The connection with the profile is established with the sealing band KERDI. Use the sealant adhesive KERDI-COLL or the installation adhesive KERDIFIX to attach the sealing band, with an overlap of at least 5 cm on DITRA 25. The sealing band should reach the angled edge of BARA-RT.
- The tiles are now installed, leaving a suitable space to the anchoring leg, which is to be filled with grout.
Installation in screed
- BARA-RT is attached at the desired level in the edge area on a layer of screed and aligned. Pre-formed corners are available for external corners. A distance of approx. 5 mm should be left between profile ends, with the gap covered by clip-on connectors.
- A load distribution layer is now formed by installing a screed mortar, which is sloped to end flush with the upper edge of the BARA-RT profile or lower, deducting the thickness of the tiles to be installed. A space of 3 mm below the upper edge of the profile must be left for the installation of the uncoupling and waterproofing membrane DITRA 25.
Note: TROBA or TROBA-PLUS should be installed between the waterproofing assembly and the screed as an area drainage.
Maintenance
BARA-RT requires no special maintenance. The coated surface of the aluminium profile is colour stable. Damaged visible surfaces can be restored with paint.
