Polyurea grouting fluid is a new type of single-component grouting
and plugging material, belonging to modified polyurea polymer
compounds. It features high solid content and high elasticity as a
chemical grouting solution that cures in water and maintains strong
adhesion in wet conditions. Using a small high-pressure grouting
machine, it cures into a dense rubber elastomer after injection
into holes and gaps, creating a tight seal. After curing, it does
not foam or shrink, maintaining a tough rubber shape for long-term
plugging effects. Being solvent-free, it prevents concrete surface
contamination. Projects using this material experience minimal
leakage and require no rework. For gaps larger than 2mm,
traditional drilling and nailing grouting techniques can be
replaced with pressure filling methods, significantly reducing
labor costs.
STEP 1: Drill diagonal holes along both sides of the crack,
ensuring penetration through the crack
STEP 3: Pour material into grouting machine and begin grouting,
filling entire gap from bottom to top
Multiple stretching effects effectively resist surface cracking
recurrence.
Demonstrates strong toughness through multiple pull-up tests.
Superior film forming strength with excellent aging resistance,
wear resistance, and long service life.
High Solid Content Without Shrinkage
Strong toughness, high elasticity, excellent crack adhesion, and
superior adaptability unaffected by thermal expansion and
contraction.
Superior Adhesion: Outperforms epoxy resin in adhesion strength.
Enhanced Performance: Superior strength and high pressure resistance compared to
polyurethane.
Machine Construction for Deep Plugging
After sealing and fusing with the substrate, the product gradually
solidifies and firmly adheres, achieving deep sealing and
waterproofing effects.
Self-Healing and Blister Resistance
Automatic repair after puncture without water leakage.
Advanced Technical Features
Solid Content >95%: High solid content enables construction and formation on any
irregular structure with curved, inclined, or vertical surfaces.
Self-Flowing Seam Recognition
Polyurea products feature innovative self-flowing permeable crack
technology.
Automatic Leakage Detection
Superior permeability allows easy penetration of small molecules
into concrete micro-cracks for deep penetration.
Temperature Performance
Excellent weather resistance with high and low temperature
tolerance - no deformation at high temperatures, no cracking or
hardening at low temperatures.
High Temperature Resistance
Maintains integrity without deformation in 100℃ boiling water.
Low Temperature Performance
Resistant to -25℃ low temperatures without cracking.
Underwater Application
Can be bonded and cured effectively in water environments.
High Resilience Performance
Polyurea material withstands settlement and cracking with strong
coating toughness and high adhesive strength (approximately 4MPa
concrete bonding).
Superior Adhesion and Flexibility
Strong adhesion and toughness prevent cracking during building
settlement and displacement, providing superior joint filling
performance and durability.
Maintains gap sealing during wall expansion and contraction from
thermal changes.
Impact Protection
Polyurea protection shields construction surfaces from weathering,
corrosion, oxidation, UV radiation, and impact damage.
