For stability the balustrade must be laid on a solid base e.g. frost protected foundation or reinforced concrete terrace. In all cases, four 8mm dia. steel reinforcing bars must be securely anchored into the base and used to reinforce the pillars. For strength and stability, pillars must not be laid more than 3m apart.

Fix the pier cap on a thin layer of Weser-Mix JM.
Plinth must be laid on a layer of traditional mortar (minimum tickness 20mm).
Cut the plinths to length using stone cutting discs. Allow 5mm joints between elements.
(Fix pairs of pins in the holes to the ends of these elements using Weser-Mix JM mortar).
(Drill holes to piers and into ends of trimmed coping/plinths as necessary).
Press a layer of Weser-Mix mortar between the elements to obtain a 5mm joint.

3
Arrange balustrers on plinths at correct spacing and bed them on 5mm Weser-Mix mortar.
Lay copings on top of the balusters, again on 5mm of Weser-Mix mortar. Fix pins (again in pairs) at the ends of these elements. Drill holes where necessary: any copings trimmed to length must have pin holes re-drilled to provide continuity of the fixing detail.
