AQUAFIN®-P 4

Elastic Polyurethane Injection Resin

Properties:

AQUAFIN-PA is a solvent-free thin liquid, two-component polyurethane resin. AQUAFIN-P4 is slow-reacting and hardens to a non-foaming, nonrigid, pore-free material which slightly foams when put into contact with water. AQUAFIN-P4 bonds to a dry, moist surface and offers an excellent adhesion and tear resistance. AQUAFIN-P4 has a low glass transition temperature and resists to winter temperatures without causing embrittlement and widening of cracks due to low temperatures without tearing.

Areas of Application:

AQUAFIN-PA is used for the close, waterproofing and elastic connection of cracks, joints and cavities in construction made of concrete, natural stone or bricks. AQUAFIN-PA is suitable for the waterproofing of car parks, concrete tanks, inner shells, construction joints, furthermore, for the waterproofing injection using injection hoses, AQUAFIN-CJ1 and AQUAFIN-CJ2 in concreting joints.

Due to its mixing ratio of 1:1 parts by volume AQUAFIN-PA is perfectly suited for the injection with the two-component-pump. AQUAFIN-P4 can be injected via packers or embedded injection hoses AQUAFIN-CJ1 and AQUAFIN-CJ2. The evaluation report of the KTW for small-area waterproofings is available.

Storage:

24 months in unopened original packs, in a cool and dry place between +10 and +30° C. Storage has to be effected in accordance with the regulations for the storage of water hazardous substances.

Method Of Application / Consumption

Generally the mixed injection resin is injected via boreholes and packers into the cracks to be waterproofed, until the material comes out of the control holes.

Example:

  1. Existing cracks (crack width approx. 0.2 mm) have to be bored in a distance of approx. 20 to 30 cm.
  2. The boreholes have to be cleaned with oilfree pressure air from the dust.
  3. Place the injection packers
  4. If required pre-isolate the packers and the crack zone on the surface, for example with ASODUR-EK98. Strip width: approx. 15 cms, consumption: approx. 300 g/m3
  5. After hardening of the crack insulation inject the thoroughly mixed AQUAFIN-P4 with suitable press. Vertical cracks: begin injecting from the bottom. Horizontal cracks: start the injection from the left side. Consumption: approx. 1.000 g/|.
  6. If necessary, remove the injection packers after thorough hardening of AQUAFIN-P4 and close the boreholes with ASOCRET-RN.
