Product description

BW6-190 hydrophilic polyurea elastomer grouting plugging agent.

BW6-190 is prepolymerized with amine-terminated polyether and isocyanate as the main resins. It is designed to enter concrete cracks under grouting pressure, react with water or moisture and form a high-toughness elastomeric plugging body.

What BW6-190 delivers for leakage grouting repair

The formulation focuses on leak plugging inside concrete cracks: penetration, reaction with water, rapid expansion, elastic sealing and durable waterproof reinforcement.

  • Elastic waterproof pluggingAfter reacting in the crack, the material forms a high-toughness, high-strength polymer elastomer for anti-leakage protection.
  • Microcrack penetrationThe data sheet positions BW6-190 for concrete microcracks less than 0.2 mm and capillary pores.
  • Rapid water reactionIt reacts readily with water or moisture and expands more than tenfold quickly after reaction.
  • Wet-crack suitabilityThe product can cure in water, has good fluidity and can react with weak acid or alkaline water without affecting plugging effect.
  • Deformation toleranceHigh strength and outstanding elasticity help the cured material adapt to structural deformation.
  • Simple one-component handlingSingle-component, solvent-free material listed as odorless, non-toxic and free of VOC emissions in the source data sheet.

Application scope

Typical use areas for BW6-190.

BW6-190 is used for concrete structure leakage grouting and plugging where water is entering through cracks, pores or joints.

Concrete leakage scenarios

  • Basements and underground spacesFor leakage grouting in large building basements, utility tunnels and civil villa basements.
  • Tanks and water-retaining structuresFor large concrete drinking water tanks and sewage tanks where crack leakage requires pressure grouting.
  • Tunnels, culverts and subwaysFor underground infrastructure leakage plugging where grouting needles can reach active crack paths.

Repair planning checks

  • Crack path confirmationClean the crack, observe overflow during water injection where possible and add needles where grout paths are incomplete.
  • Needle spacing and angleUse 45 degree inclined drilling on both sides of the crack, typically one needle every 10-15 cm.
  • Supplement until dryInsufficiently filled sections should receive extra grouting needles until there is no water seepage.

Application guide

Grouting equipment and crack repair instructions.

Follow the source data sheet sequence: crack cleaning, 45 degree grouting needles, water-checking where possible, pressure grouting and supplementary grouting until seepage stops.

Application instructions

StepApplication instruction
01Grouting equipmentUse the same equipment used for traditional foamed polyurethane grouting; no need to replace the machine when changing materials.
02Substrate treatmentClean debris and dust on and around concrete cracks; ensure the surrounding concrete is firm and clean.
03Pre-embedded grouting needlesDrill 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 cleaningIf 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 groutingPour 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 groutingEnsure cracks are fully filled. Add grouting needles for insufficiently grouted areas until there is no water seepage.

FAQ

FAQ about BW6-190 grouting leakage repair.

These answers follow the BW6-190 data sheet and focus on grouting equipment, crack preparation and leakage plugging workflow.

What is BW6-190 used for?

BW6-190 is a one-component hydrophilic polyurea elastomer grouting plugging agent for concrete structure leakage, including microcracks, capillary pores, tanks, basements, tunnels, culverts, utility tunnels, villas and toilets.

What grouting equipment is used for BW6-190?

No. The application guide specifies grouting equipment like that used for traditional foamed polyurethane grouting, so teams can change material without changing the grouting machine.

How are grouting needles arranged for cracks?

The guide calls for inclined holes at a 45 degree angle along both sides of the crack. The hole depth should penetrate the crack, with one needle every 10-15 cm and an additional 45 degree needle at crack intersections.

Can BW6-190 react and cure in wet cracks?

Yes. The product reacts with water or moisture in the crack, expands rapidly after reaction and forms a high-toughness, high-strength polymer elastomer for waterproof leakage plugging.

What should be checked during crack cleaning?

If site conditions allow, inject water with a grouting machine to clean the crack and observe whether water overflows from the crack surface. Add grouting needles where local areas do not overflow.

When should grouting continue or stop?

During polyurea grouting, continue pressing for 2-3 seconds after the next grouting needle exudes grout. Areas with insufficient filling should receive additional needles and supplementary grouting until seepage stops.
