One-component foaming polyurea grouting material for concrete cracks, leakage paths and localized waterproof repair. It expands after contact with water to help fill voids, block water channels and stop active leakage.
BW6-190 One-Component Polyurea Elastomer Grouting Plugging Agent is a hydrophilic polyurea elastomer plugging material, prepolymerized with amine-terminated polyether and isocyanate as the main resins. After pressurization by a grouting machine, the agent can penetrate into the microcracks of concrete structures and react with water or moisture present in the cracks. This product exhibits rapid reactivity with water, and its volume expands more than tenfold quickly after the reaction, forming a high-toughness and high-strength polymer elastomer. Endowed with high permeability, high bonding strength, high expansion rate and flexibility, it can rapidly seal microcracks (less than 0.2mm) and capillary pores of concrete structures, providing permanent waterproof and anti-leakage protection.
Application Scope
BW6-190 is used for grouting plugging engineering in concrete-structure leakage scenarios, including drinking-water and sewage tanks, building basements, subways, tunnels, culverts, utility tunnels, villa basements and toilet leakage repair.

Basements and utility tunnelsPressure-injection repair for large building basements, civil villa basements and basement utility tunnels.
Subways, tunnels and culvertsGrouting repair where concrete leakage paths can be reached with suitable needle layout and injection pressure.
Toilets and facility leakageConcrete-structure leakage repair where water-reactive crack filling is appropriate after site review.
Designed for Water-Reactive Crack Plugging
BW6-190 helps applicators pressure-inject a hydrophilic elastomer into concrete leakage paths. It is suitable when a project needs crack penetration, rapid water reaction and an expanded plugging body inside the structure.

Application instructions
Product data table
Step
Application instruction
01Grouting equipment
Use the same equipment used for traditional foamed polyurethane grouting; no need to replace the machine when changing materials.
02Substrate treatment
Clean debris and dust on and around concrete cracks; ensure the surrounding concrete is firm and clean.
03Pre-embedded grouting needles
Drill inclined holes at a 45° angle along both sides of the crack. Hole depth must penetrate the crack. Set one needle every 10-15 cm and add a 45° needle at crack intersections.
04Crack cleaning
If conditions permit, inject water for crack cleaning and observe whether water overflows from the crack surface. Add needles where local areas do not overflow.
05Polyurea grouting
Pour the grouting agent into the hopper and start water-stop reinforcement grouting. Continue pressing for 2-3 seconds after the next needle exudes grout.
06Supplementary grouting
Ensure cracks are fully filled. Add grouting needles for insufficiently grouted areas until there is no water seepage.

FAQ about BW6-190 hydrophilic grouting material.
These answers stay focused on grouting equipment, water-reactive crack filling and leakage plugging workflow.
BW6-190 is a one-component hydrophilic water-reactive grouting material for pressure injection into concrete cracks, capillary pores and active leakage paths.
No. BW6-190 is not a surface coating. It is injected under pressure into concrete cracks or leakage paths, where it reacts with water or moisture and forms an elastomeric plugging body inside the structure.
It reacts with water or moisture inside the crack and forms an elastomeric plugging body. Use the listed 800-900% foaming-rate data for expansion review.
It can be reviewed for concrete crack leakage, capillary-pore sealing, basement leakage repair, tunnel or culvert leakage and concrete tank or underground-structure grouting.
The guide references traditional foamed-polyurethane grouting equipment and 45 degree inclined holes, typically with one needle every 10-15 cm along the crack path.
Confirm the leakage path, water condition, concrete soundness, injection pressure, needle spacing and whether structural movement or damage requires separate engineering assessment.
