PU Injection Resins

WEBAC® 1403P CE

WEBAC® 1403P is a CE-certified PU injection resin for crack injection in concrete elements. In contact with water the resin reacts to a fine-pored closed cellular foam with high chemical resistance, specially for contaminated facilities in agricultural sector and waste water disposals.

Range of Application

  • Crack repair in concrete according to EN 1504-5
    (CE Declaration of Performance/2+)
  • Injection of injection tubes (National Test Certificate)
  • Repair of waste water facilities and sewer repair
  • Sealing of construction joints
  • Sealing of foundation pits


Properties

  • Mixing ratio 1 : 1
  • Low viscosity
  • Good elasticity
  • High chemical resistance
  • Adjustable reaction time (accelerator WEBAC® B14)
  • With accelerator also suitable for use at low temperatures
  • Total solid


Application



WEBAC® 1403P: injection resin for closing, sealing and filling cracks

WEBAC® 1403P is a high quality, very low viscosity PU injection resin. WEBAC® 1403P is used for the closing, sealing and limited-flexibility filling of water-bearing, damp or dry cracks. The PU injection resin is also suitable for injection procedures via injection tubes to seal construction joints in concrete structures. WEBAC® 1403P is certified according to DIN EN 1504‑5 for areas relevant to structural stability (PU resin CE sign).


Fully cured WEBAC® 1403P provides for constant volume and chemical resistance

WEBAC® 1403P cures to form an inert, chemical-resistant resin of constant volume. Please note that lower temperatures will slow down the reaction, whereas higher temperatures will accelerate the reaction. At low temperatures (<10 °C) it is recommended to add accelerator (WEBAC® B14). The injection resin WEBAC® 1403P stands out due to its compatibility with masonry mortar,  concrete, steel, foil and cable sheathing materials. 

In case of water-bearing cracks under hydrostatic pressure it must be checked on site whether a preliminary injection of WEBAC PU injection foam resin is necessary. A preliminary injection is always required if the water pressure is so high that the injection resin would otherwise be washed out of the structure before it has fully reacted.
