Support the wall the proppa way.™

Step 1 Mark out your proposed new opening and determine the opening height and proposed position for the lintel. Rake or grind out the mortar joint one or two bricks above the joint in which you are working to ensure that the PROPPA® has clearance and will slide into the clean joint until the web of the PROPPA® is against the face of the wall. Under no circumstances should you hammer in the PROPPA® as this can cause cracking. Ensure that the floor or foundation is capable of providing adequate bearing capacity for the base of the props without settlement or sliding. Ensure an engineer has checked the adequacy of the masonry wall containing the proposed opening before any work commences including lateral resistance at the prop level during its use.

Step 2 Once the PROPPA® is in position, locate the prop, ensuring that the prop is plumb when it is tightened. Note: if you are supporting a double skin, carefully insert a steel wedge to pick up the outside skin if required. Take up the load on the prop, do not over-tighten. This is not a jacking device. The more detailed Instructions for Use contain a safe working load table to assist in determining the maximum safe working load at a given height. This table is a general guide only and is NOT intended as a substitute for the engaging of a structural engineer to determine safe working loads and general propping details/layout. Once props are correctly positioned, carefully remove the appropriate bricks and install the lintel. The brickwork below the installed lintel should be removed carefully and ONLY after the lintel has been permanently secured in place and its supporting new mortar has been fully hardened.

Step 3 After safe removal of the props and the PROPPA®s, go about fixing the holes in the mortar where the Proppas were situated. If there’s any settlement or movement of the masonry wall during the process of installing the PROPPA® wall supports, removing masonry units, installing the lintel or removing the props, check for any cracking in the masonry and conduct repairs as necessary. Always use PROPPA® wall supports in a safe and workmanlike manner and comply with O, H & S / Work Health and Safety regulations and any local or site specific requirements.
