How to anchor a metallic masonry element

Onsite we must frequently anchor metallic elements such as claws, piping, toilets, pre-frames and hinges, urban furniture, signage, etc., which must be quickly put into operation.

Traditional materials such as fast-setting cement, gypsum or plaster are not the most adequate products, as they oxidize the metallic element in question, in addition to suffering too much retraction, cracking and consequently weakening the required anchorage.

Preliminary analysis

When fixing a metallic anchorage, we must use a mortar compatible with the substrate and the metallic anchorage, due to which it must be:

  • Highly weather resistant
  • Highly adherent to metallic elements
  • Resistant to cracking
  • Fast setting and have compensated retraction
  • Watertight to avoid oxidation of metallic elements.

Technical considerations

The work to be carried out must be thought through beforehand:

 

  • Affixing of clamps, hinges and braces: 

Fill the hole in the bracket with GECOL Pronto and gradually insert the element to be affixed.

 

  • Affixing of street furniture and signage:

Fill the cavity with GECOL Pronto, GECOL Prontocem or GECOL Cemento rápido and gradually introduce the element to be affixed. 

 

  • Placement of pre-frames and frames: 

For the installation of this type of element, where corrections may be necessary, we can seal the claws with GECOL Prontocem.

 

  • Placement of manhole covers and drains:

Apply the required amount of GECOL Pronto and place the element to be affixed.

 

For GECOL Pronto and GECOL Cemento rápido, being respectively a technical mortar and an ultra-rapid setting cement, it is advisable to prepare only quantities that can be used in 1 – 2 minutes. 

 

The quantity of water has a proportional effect on the speed of setting. The greater the quantity of mixing water, the longer the setting time, as the product is rehydrated by this excess water.
