High Elastic Polyurea Grouting Fluid Waterproofing Materials
Polyurea grouting fluid is a new type of single component grouting and plugging material, belonging to modified polyurea polymer compounds. It is with high solid and high elastic chemical grouting that can curing in water and has strong adhesion in water. Using a small high-pressure grouting machine, it cures to be a dense rubber elastomer after being injected into the holes and gaps, and tightly seals the gaps in the holes. After curing, it does not foam or shrink, and maintains a tough rubber shape for a long time, achieving a long-term plugging effect. Due to it is solvent-free, it will not cause contamination on the surface of concrete. The used projects have almost no leakage and do not require rework. For gaps larger than 2mm, traditional drilling and nailing grouting techniques can be used to block leaks, and instead, the pressure filling method can be used for construction, greatly reducing labor costs.

Advantages
—
Solving the problem of easy blockage in large water and difficult treatment in small water
● It can fully curing in water, and has good bonding with concrete on damp surfaces or in water;
●The internal structure is dense and has good impermeability;
●Curing is not sensitive to temperature and can be cured at high or low temperatures.
Solve the problem of blockage and continuous leakage
●Having a certain strength and elasticity, it can be reinforced and adaptable
●No shrinkage in the later stage.
Good durability
●Resistant to water immersion, acid and alkali, and high and low temperatures;
●Environmentally friendly and non-toxic, harmless to the human body.

Operation Notes
—
1. There should be no open water on the base surface of the project, otherwise construction should be done 24 hours after it is drained
Construction should be carried out at temperatures above 5℃. The construction site should be well ventilated and fire-fighting equipment should be placed.
2. After opening the barrel, it should be used as soon as possible, and the time should not exceed 15 minutes; avoid direct exposure to the air for 3. a long time to prevent skin formation.
4. After opening the lid, the unused material should be tightly closed immediately and the remaining material should be used up as soon as possible.
5. Pay attention to protecting the construction site before it is completely dry.

Construction Process
—
Easy to operate, only three steps are needed to seal the leak
STEP 1:Drill diagonal holesalong both sides ofthe crack, payingattention to drillingthrough the crack
STEP 2:Install grouting nailsand tighten them
STEP 3:Pour the materialinto the groutingmachine and startgrouting, filling theentire gap frombottom to top

Why choose Polyurea?
—
High solid content,without shrinkage: Strongtoughness, high elasticity,strong adhesion to cracks,strong adaptability, not affected by thermal expansion and con-traction to prevent leakage
High solid content,without shrinkage:
Compared with epoxy resin,Compare adhesion strength.
Compared with polyurethane,Comparative strength,high pressure resistance.
Machine Constructiondeep Plugging:
After the product is sealed and fused with the substrate,it gradually solidifies and firmly adheres to the supply surface,achieving the effect of deep sealing and waterproofing
Self-Healingresistant To Blisters:Automatic Repair After Puncture Without Water Leakage
Infiltration Leak Sealing / Pilot Leak Sealing / Strong Stretching Force
Solid content>95%:High solid content, can be constructed and formed on anyirregularstructure with curved,inclined, orverticalsurfaces
Self Flowing Seam Recognition:Polyurea products have a new self flowing permeable crack technology
Compared with polyurethane,Comparative strength,high pressure resistance.
Automatic Searchleakage Pointdo,Not Miss Any Leakage Holes:
Superstrong permeability, easy penetration of small molecules,able to penetrate into small cracks in concrete, playing a deep penetration role
Good Weather Resistance,High And Low Temperature Resistance
High temperature resistance without deformation, frost resistance without cracking or hardening
High Temperature Resistance:No Deformation In 100℃ Boiling Water
Resistant To Low Temperature Of -25℃ Without Cracking
It Can Be Bonded And Cured In Water
High resiliencefearlessofsettlementand cracking
Polyurea material, with strong coating toughness and high adhesive strength, can bond with concrete with a strength of about 4mpa resistant to peeling and non peeling
Strong adhesion, strong toughness, buildingsettlement and displacement, adhesive still doesnot crack, stronger joint filling performance, andmore durable
The wall expands and contracts due to heat, and the gaps becomelarger. Polyurea still firmly blocks the gaps as they stretch
