Anchoring metallic elements in concrete

To anchor prefabricates, heavy machinery and other metallic objects in concrete substrates, it is necessary to use mortars with very specific technical characteristics.

The solution lies in using PROPAM® GROUT, that is, a mortar with high mechanical performance, compensated shrinkage, fluid consistency and great adherence so that it can adapt perfectly to the irregularities of the container in which the metallic element will be housed, ensuring its stability.

SUBSTRATE PREPARATION

The substrate must be firm, rough and free of oils, paints, demoulding agents, dust, etc.

Moisten the substrate with water until saturation, prior to the application of PROPAM® GROUT.

In drill fillings remove dust and dirt debris as well as water soaked from the holes by blowing air under pressure.

APPLICATION

Mix PROPAM® GROUT according to the instructions given in the technical data sheet. Use a low speed drill or a traditional concrete mixer, let stand 5 minutes and re-mix to obtain a paste ready for use.

Fill in the hole provided. Avoid long distances between the place of mixing and the place of work in order to avoid possible decantation.

Once poured, PROPAM® GROUT must be protected from the sun, wind, etc. It is advisable to cover it with wet cloths or polyethylene sheets for 2 or 3 days. The curing operation is essential in all cases.

Recommendations

  • Applicable thickness from 5 to 50 mm.
  • For filling, it is convenient to pour the material using a rod.
  • In fillings under plates, a conduit must be provided for the air, facilitating the exit of this during the filling with PROPAM® GROUT.
  • In filling deep drillings the air outlet must be secured by placing a plastic tube that will be slowly extracted.
  • In case of use of mortar with plastic consistency it will be necessary to help compaction with a slight vibration.
  • In the case of fillings with thicknesses greater than the maximum indicated, the formwork must be maintained for at least 3 days.

Technical mortars

Build a barbacue

Making barbecues, chimneys, ovens, etc., requires using specific materials that withstand the extreme conditions to which they are going to be exposed (high temperatures, expansions and contractions, etc.). The solution lies in using PROPAM® REFRACTARIO, a refractory mortar which, due to its technical characteristics, is suitable for coating walls and making joints that are subject to environments in contact with fire or high temperatures. The abrupt changes in temperature that occur when lighting barbecues, fireplaces, ovens, etc., produce dilations. When turning off facilities, contraction movements in the materials used are produced. These changes can produce cracks and even lead to loosening, if the materials used for its...

Build a wall with glass blocks

A glass block is a very useful material both in construction, decoration and interior decoration, as it can be used to separate different ambiances, showers, outside walls, or simply as decoration. It is formed by two pieces of molded glass, which are welded at a very high temperature, to create a vacuum air chamber between the two pieces. This air chamber confers the capacity of thermal-acoustic insulation. Once placed provides highly decorative finishes, given the wide range of formats and colors.

Fixing glass wool in an enclosure chamber

The need to obtain efficient thermal insulation and even more so since the TBC came into force a few years ago, has lead the construction industry to develop materials like glass wool, for use as thermal insulant and acoustic absorbent in enclosure walls inresidential, commercial, industrial and service buildings. For its correct placement it is necessary to use a mortar that allows the waterproofing of the enclosure against water that can penetrate from the outside, without forming a vapor barrier.
