Sikadur®-53 - Epoxy Crack Injection And Grouting Resin
Verified by manufacturer 1 day ago
Epoxy crack injection and grouting resin for all conditions, including wet and underwater.
Application
- Crack injection resin to seal damp and wet cracks by high pressure injection.
- Fills and seals voids and cracks in structures such as bridges, civil engineering structures, industrial and residential buildings (e.g. columns, beams, foundations, walls, floors, water retaining structures, etc.).
- Structural bonding.
- Preventing ingress of water and infiltration of reinforcement corrosion promoting substances.
- As a grouting resin or adhesive for bonding concrete and steel underwater (by water displacement).
Description
Sikadur®-53 is a two-part, epoxy, moisture-resistant crack injection and grouting resin.
Features and benefits:
- Suitable for dry, damp, wet and underwater conditions.
- Application temperature range +5 to +30°C.
- Shrinkage-free hardening.
- Seals against moisture and oxygen.
- Good adhesion to concrete, masonry, stone and steel substrates.
- Good adhesion to salt water immersed, cementitious substrates.
- High density ensures good water displacement.
- Good mechanical underwater strengths.
- Minimum crack widths 0.5 mm.
- Injectable with single component pumps.
Approvals/ standards:
- CE Marking and Declaration of Performance to EN 1504-4 - Structural bonding.
- CE Marking and Declaration of Performance to EN 1504-5 - Concrete Injection.
- CE Marking and Declaration of Performance to EN 1504-6 - Anchoring of reinforcing steel bar.
