To be read in conjunction with GAR1/TS, B50/TS, appropriate balustrade Tech Sheets and Pointing Recommendations. The balustrade is supplied in component form: ie piers (cap, shaft, base and optional pier undercoping), rail, baluster, plinth and optional undercoping.

All rails, plinths and undercopings are supplied in standard lengths, cutting and drilling being undertaken by the installation contractor. An optional Balustrade Installation Pack X950 (UK only) is available on request.

Unless otherwise stated, all materials other than the stonework are to be supplied by others. Consult a qualified builder or installer to ensure all relevant Building Regulations/Codes are adhered to prior to installation of balustrade.

The balustrade should be erected on a suitable foundation. The foundation, concrete and steel reinforcement to be designed by others to suit loading and ground conditions. Shown is a pier base, pier undercoping, plinth and an undercoping bedded on 1:1:6 cement/lime/sand mortar. All joints would normally be 6mm (1∕4”) with the mortar slightly recessed from the surface of the stonework to allow for pointing after the balustrade is erected.

Mark the pier base centrally and drill a 20mm (3∕4”) hole through the pier base and pier undercoping and into the foundation. Similarly, the undercoping and plinth should be drilled to a diameter of 10mm (3∕8”) and dowelled twice per stone into the foundation. Ensure that holes are positioned so that they will eventually be hidden by balusters.

Resin fix a 10mm (3∕8”) stainless steel dowel positioned to extend 300mm

(12”) above the pier base. The pier shaft can then be bedded, using the method previously described.

It is important that polystyrene/Styrofoam (or similar) is used to act as an isolating/expansion medium between the stone and the infill concrete.

This is inserted into the core of the pier shaft prior to filling with concrete.

Care should be taken to ensure sufficient overlap at the vertical joint with continuous contact between the isolating/expansion medium and the inner stonework core. The pier shaft is then infilled with concrete and hand compacted. The coarse aggregate of the concrete being rounded gravel of maximum 10mm (3∕8”).

ASSEMBLY

RECOMMENDATIONS

Mark and drill plinth to create 16mm (5∕8”) holes to allow for tolerance ready for balusters at desired spacing in accordance with Tech Sheet B70

Bed the balusters on plinth with the dowels resined ensuring any seam marks run lengthways along the plinth.

9 10

Mark and drill the underside of the rail to create 16mm (5∕8”) holes ready for balusters at desired spacing ~ enlarge holes if necessary to allow for installation tolerance. Also drill and resin 6mm (1∕4”) dowels to both ends of the rail. Final assembly of this section can now take place with the rail being bedded on a mortar bed.

The finished balustrade is then ready for pointing. For details refer to the Pointing

Recommendations sheet.

The isolating/expansion material is trimmed and the concrete trowelled so that both are flush with the top of the shaft. Insert 10mm (3∕8”) stainless steel dowel 100mm (4”) long minimum into top of concrete, to protrude by

40mm (11∕2”). Only proceed once concrete has reached its initial set.

Drill a 20mm (3∕4”) hole in underside of pier cap and drill a 16mm (5∕8”) hole in the side of the pier cap at the rail run-in ready for the rail installation. Resin dowel and bed the pier cap on a continuous mortar bed on the pier shaft.

Required: pointing mix, pointing trowel, masking tape, mixing bowl, water, mist sprayer.

Please note: all text and photographs relate to Haddonstone semi-dry pointing mix.

Before pointing ensure each 6mm (¼”) joint is free from loose particles. Avoid pointing in extreme conditions, particularly wet and cold.

Apply masking tape to both sides of the joint, keeping the tape approximately 1mm (1/16”) from the edge of the joint.

The joint is now ready to start pointing.

The Haddonstone pointing mix is ready to use when it has the consistency of damp sand. *See note below.

Scoop the mix into the joint, pressing with a trowel to ensure an even fill.

Smooth the pointing mix to the profile of the stone, removing any excess pointing mix.

Carefully remove the masking tape.

If necessary trowel over the joint once more to ensure a flush finish.

Apply a fine and even mist of water to the joint to prevent drying out.

Any mix residue may be rubbed away with fine abrasive paper 2-3 days after completion.

The finished joint.

Carefully add small quantities of water to the Haddonstone pointing mix, mixing thoroughly to ensure the water is fully dispersed.

*See note below.

* NOTE: It would be advantageous to use a waterproofing additive in the mixing water (SBR or other proprietary mortar admixture). The use of too much water can lead to the pointing mix colour and texture becoming unsightly, and the possibility of the mix bleeding into the adjacent cast stone.

TECSTONE POINTING

RECOMMENDATIONS

Required: pointing mix, pointing trowel, masking tape (if required), mixing bowl, water, sponge.

Please note: all text and photographs relate to TecStone pointing mix.

Before pointing ensure each 6mm (1∕4”) joint is free from loose particles. Avoid pointing in extreme conditions, particularly wet and cold.

The TecStone pointing mix is supplied as separately bagged cement and aggregate with an information leaflet.

Carefully add small quantities of water to the TecStone pointing mix, mixing thoroughly to ensure the water is fully dispersed.

*See note below.

The TecStone pointing mix is ready to use when it has the consistency of putty. *See note below.

Scoop the mix into the joint, pressing with a trowel to ensure an even fill.

Smooth the pointing mix to the profile of the stone, removing any excess pointing mix.

If necessary trowel over the joint once more to ensure a flush finish.

Wipe over the surface of the joint and surrounding area with a dampened sponge to remove all surplus pointing material off the surrounding areas and ensure a flush finish to the joint.

Any mix residue may be rubbed away with fine abrasive paper 2-3 days after completion.

The finished joint.

The cement and aggregate should first be mixed together dry in the ratio of 1 part cement to 4.5-6.5 parts aggregate.
