10.0 Tools & Equipment for Construction

Hebel PowerBlocks can be laid using construction tools/equipment.

String Line – A string line is required to accurately set out and lay Hebel PowerBlock Walls.

Brick/Blocklaying Profiles – used to gauge the block course are being laid level.

Mixing Bucket – a minimum 20 litre bucket is required for mixing Hebel Mortar, Hebel Adhesive and Hebel HighBuild render.

Electric Drill – an electric drill is required to mix the Hebel Mortar, Hebel Adhesive and Hebel HighBuild render. It is also used to drill clearance holes in the blocks so they can be placed over the tied down rods where required.

Stirrer – fitted to the electric drill, the stirrer is used to mix the Hebel Mortar, Hebel Adhesive and Hebel HighBuild render inside the mixing bucket.

Notched Trowel – the notched trowel is used to apply the Hebel Adhesive to the Hebel surfaces. The width of the trowel must match the block thickness to ensure the adhesive is applied with full and even coverage.

Rubber Mallet – a rubber mallet is required to ‘tap’ the Hebel PowerBlocks onto the adhesive and into place.

Spirit Level – required to install the blocks level and plumb.

Hand Saw – a Hebel handsaw can be used to cut Hebel PowerBlocks to length and height.

Powered Bandsaw – a bandsaw is ideal for cutting Hebel PowerBlocks. (perfect when there are many site cuts to be performed).

Hebel Square – a purpose built square is available for use when marking and cutting Hebel PowerBlocks.

Steel, Plastic and Timber Trowels – these trowels may be required for the installation of the Highbuild render and texture coatings.

Sanding Float – used to even out inconsistencies in the Hebel PowerBlock Wall in preparation for render/texture coats.

Hebel Hand Router – may be used to chase services into solid Hebel walls.

Circular Saw – (fitted with a diamond blade) may be used to chase services into solid Hebel walls.

Electric Router – may be used to chase services into solid Hebel walls.

Crane – may be required to lift large Hebel Lintels and Hebel custom floor panels.

Lifting Grabs – required for use in conjunction with crane for lifting Hebel lintels and custom floor panels.

Scaffold – Scaffold is required when building block walls. The amount of scaffold depends on the height of the walls.

Sealant Gun – required to fill the control joints in the Hebel PowerBlock Walls.

Appendix A – Carpet Installation

Panel Surface Preparation

Sweep the floor surface to remove debris and loose particles. Expose all surface blemishes such as chips, cracks, gaps, ridges or the like. Fill all unacceptable locations with an appropriate and compatible patching compound such as Hebel Patch or levelling compound as required. Ensure panels are then dry.

Carpet Smooth Edge Installation

Installation of Carpet Smooth Edge (Gripper) is to be in accordance with AS/NZS 2455.1:1995.

Installation of carpet gripper prior to laying carpet requires the use of specifically selected nails or course threaded screws. Standard fixings supplied with the carpet gripper are not suitable for fixing to Hebel PowerFloor panels. Carpet gripper strips are available without factory supplied nails. For carpet gripper installation near the panel edge, only glue is recommended. If relying on glue only, the carpet can not be stretched until the glue is set after approximately 24 hours.

5 Coating Systems QT Eco Series

5.1 Coating /Rendering

The proprietary coating systems consist of polymer-modified cement renders, which must be finished with an acrylic texture and paint. The proprietary coating manufacturer’s instructions and application requirements must be followed at all times.

*(Available to download from the QT website) In most cases these coating systems must be applied by an approved applicator. High profile or heavy texture finishes can minimise surface imperfections or glancing light concerns. Light coloured coatings are recommended. Polymer-modified cement renders must not be applied over sealants or control joints.

5.2 Pre – Coating System Inspection

Check all internal and external corners are formed correctly and have good straight lines. Check the first horizontal course, and panels above rooflines have a good clean bottom line. Check weep holes have been installed in the first horizontal course. With a 1.8m spirit level check for variations greater than 3mm in the QT EcoSeries Wall Panels, especially where panels butt together. If variations are found, take the appropriate remedial action eg. rasp to an acceptable level, or re-fix the offending panels. It is important to eliminate large variations, as they may appear under critical or glancing light conditions. If the internal lining has not yet been installed, advise the building supervisor that internal wall lining cannot be installed using nails as the knocking vibrations will transfer through the frame and crack the render coatings (hairline cracking).

Hence internal lining must be screwed. After the inspection has been completed, application of the base coat can begin.

5.3 Application of a Polymer Modified Render Base Coat

Trowel an even coat of polymer-modified cement render over the entire QT EcoSeries Wall Panel, embed QT FullMesh into the wet Render, overlapping joints by 100mm minimum. Allow to firm and then screed and or float to a flat and level finish. The purpose of this coat is to even out the substrate and the porosity of the QT EcoSeries Wall Panel. 150mm wide x 300mm long strips of QT 45° Mesh are also required to be set into the base coat at 45° angle across the corner of all windows and door openings into wet render. Do not render or texture over control joints. The above is a generic guide only.

Refer to the proprietary coating manufacturer’s instructions for a detailed description of application. Any proprietary coating system specified must meet or exceed the performance criteria of the BCA.
