MAXREST ® is a one-component structural repair mortar, composed of special cement, additives and selected aggregates, which provides a thixotropic product with quick-setting and shrinkage-compensated. Meets Class R4 according to European Standard EN-1504-3.




  1. Restoration of structural concrete elements, recovering original shape and function. EN 1504-3 standard, Principle 3 (CR) – Method 3.1 Applying mortar by hand in:
    * Repair of general structural concrete on vertical or overhead surfaces, without form works. Repair of honeycombs, cracks, and fissures.
    * Repair of pillars, lintels, rain caps, and architectural concrete exposed permanently to weather condition.
    * Repair of lines and shapes in prefabricated concrete elements and structures damaged by mechanical impacts, corrosion of reinforcements, freeze/thaw cycles, etc.
  2. Structural strengthening of concrete elements. EN 1504-3 standard, Principle 4 (SS) – Method 4.4 Adding mortar.
  3. Restoration of passivity for rebars on concrete elements. EN 1504-3 standard, Principle 7 (RP) – Method 7.1 Increasing cover to reinforcement with mortar, and Method 7.2 Replacing contaminated concrete in:
    * Repair of concrete structures subject to the carbonation process.
    * Increasing cover for concrete structures.
  4. Patching of cold joints and making of concave corners prior to waterproofing jobs in reservoirs, swimming-pools, basements, etc.


  1. Quick-setting time: from 15 to 20 minutes. The repair can be accomplished in a single phase and in an agile process.
  2. High adhesion to concrete and reinforcements. No special bonding agent/primer is required. Loads are transmitted onto the repaired structure. It forms part of the substrate and repairs are structurally sound, and stable.
  3. Mechanical properties are comparable to or higher than concrete.
  4. Good thixotropy. Application in successive layers without slump or the need to use formwork. Allows high thickness per layer from 10 to 30 mm.
  5. It does not shrink, avoiding the risk of cracks when sets.
  6. Odour-free, making it the ideal material to use in badly ventilated places, such as water tanks, shafts, sewers, etc.
  7. Does not contain any chloride.
  8. Easy to mix and use: one-component mortar, just adds water, and apply by trowel.
  9. Environmentally friendly: non-toxic, cement base and solvent-free product.
