APPLICATION PROCEDURES

  1. Remove the mortar from the joints to a depth > 3 cm.
  2. Dedust the joint surfaces by washing with low pressure water.
  3. Put on the scarified joint an adhesive latex primer, multifunctional, in a light colored viscous solution, based on acrylic polymers in aqueous dispersion, coalescing promoters, deaerating agents and special superpozzolanic reaction fillers, BOND HG, pure or diluted in water 1:1 (depending on the absorption of the substrate).
  4. Reinforcing the mortar joints on existing wall faces, by anchoring HELIX STEEL AISI 304 helical bars in stainless steel with UNISAN (*) composite mortar, fiber-reinforced with double type of READYMESH fibers (glass and polypropylene), dehumidifying, with very high breathability, class R (restoration according to UNI EN 998/1), based on hydraulic binders with a low content of soluble salts, with mechanical resistance in class R2 (according to UNI EN 1504/3), reaction to fire class A1 (EN 13501-1), permeability to water vapor 11 μ (UNI EN 1015-19), compressive strength after 28 days > 20 N/mm² (UNI EN 12190), flexural strength after 28 days > 5MPa (UNI EN 12190) elastic modulus 11 GPa (EN 13412), maximum particle size of the aggregate 1.5 mm.
  5. Insert at least a couple of cm of UNISAN mortar into the scarified joint (*); with the mortar still fresh, introduce the helical stainless steel bar, diameter 6, 8, 10 or 12 mm in the joint, depending on the size of the joint and the need for reinforcement, taking care to incorporate it into the still fresh mortar; complete the incorporation of the mortar and the filling of the joint with a final grouting performed fresh on fresh with UNISAN mortar (*); mortar consumption of 1.5 kg for each dm³ of joint volume

* as an alternative to UNISAN mortar, the super adhesive RASOCOAT mortar can be used, based on hydraulic binders, water-dispersible resins, silico/limestone aggregates and specific agents. Main technical characteristics of RASOCOAT mortar : Adhesion bond (UNI EN 1015-12): > 1.5 N/mm²_ Density: 1.90 kg/l _ Compressive strength after 28 days (UNI EN 1015-11): > 20 MPa _ Flexural strength after 28 days (UNI EN 1015-11): > 6 MPa

Application stratigraphy

  1. Application of BOND HG primer in the scarified joint
  2. Insertion of “helical bar” drowned with UNISAN mortar
  3. Re-styling of the joint with UNISAN mortar

SYSTEM COMPONENTS

 

 

HELIX STEEL AISI 304


AISI 304 stainless-steel helical rod is cold drawn, with elevated mechanical benefits for reinforcing joints and connections, including through-holes, on masonry, reinforced concrete, arches and vaults. Suited to consolidating structures in seismic areas. Beneficial in conjunction with hydraulic binders (cement and hydraulic lime) and with resinous matrix binders, it particularly facilitates the achievement of physical-mechanical benefits in combination with UNISAN mortar, with products form the REPAR family, GROUT, and with the structural resins of the SYNTECH family.

UNISAN


A composite mortar that is fibre-reinforced, consolidating, dehumidifying, grey in colour and utilised for the structural restoration of crumbling old or monumental masonry. It contains no substances that are potentially harmful to masonry and is composed of NHL 3.5 natural hydraulic lime and hydraulic binders free from soluble salts, along with silicas with pozzolanic activity, selected siliceous-calcareous aggregates, specific shrinkage-reducing agents and resistant alkaline READYMESH fibres that confer high flex-traction whilst increasing the performance of the mortar’s fracture energy. In conjunction with ARMAGLASS STRUCTURA fibreglass mesh, it is ideal for the structural restoration of old walls or crumbling constructions.
