re-plate 120/1.5 strengthening solutions

«for statically loaded elements»

The memory®-steel strip re-plate 120/1.5 is used for minor strengthening of slender concrete slabs in building construction (dry areas indoor, X0 and XC1). re-plate is anchored on both sides and functions as an external, unbonded tension strip. re-plate is elongated in the factory and supplied pre-punched at the ends ready to use on-site. The mechanical end anchorage is composed of a Hilti direct fastening system. For activation of the prestressing, the plate is heated using a gas burner or infrared heater.

Plaster, paint coats and insulation must be removed from the substrate beforehand. re-plate is cleaned on both sides according to the method statement. After the installation and prestressing, re-plate is sealed on all sides with Sikaflex® PRO-3 Purform to prevent water ingress between concrete substrate and the strip. A corrosion protection (Macropoxy® EG-1 Plus, formerly SikaCor® EG-1 Plus) is applied to the cleaned surface on the outside. A corrosion protection on both sides of re-plate is possible. This is already applied in the factory. Learn more

Advantages
  • Easy-to-install flexural reinforcement for concrete
  • Active, instant load-caryying reinforcement (prestressing)
  • Minimal space requirement
  • Reduction of deflections and crack opening
  • Increased performance under service load
  • Stress release in the internal reinforcement
Tested Sika products

Fire protection:

  • SikaCem® Pyrocoat sprayed fire protection mortar
  • SikaCem® Pyrocoat Base Sprayed basecoat for the Pyrocoat fire protection mortar

Corrosion protection:

  • Macropoxy® EG-1 Plus (former SikaCor® EG-1 Plus) Corrosion protection coating: epoxy-based intermediate coating containing MiO
  • Sikaflex® PRO-3 PU joint sealant for bilateral grouting of re-plate

memory®-steel has been tested in systems with Sika fire and corrosion protection products. re-fer gives no guarantee if other mortars and products are used in combination with memory®-steel.

 

Combining measures

Combination of re-plate and Sika® CarboDur®:

re-plate

  • Against deflection and cracks in the deck slab and the wall element above
  • To relieve load on the existing internal reinforcement
  • To cover the loads at serviceability state and under fire

Sika® CarboDur® CFRP-laminates

  • To cover the remaining failure load requirement
