Product Description

BW6-190 is a one-component hydrophilic polyurea elastomer grouting material based on amine-terminated polyether and isocyanate prepolymer chemistry. When injected under pressure, it can enter accessible microcracks and capillary paths in concrete and react with water or moisture to form an expanded elastomeric seal. The technical data lists an 800-900% foaming ratio under the stated test conditions. Actual expansion, crack filling and leakage-control performance depend on moisture, crack geometry, injection pressure, substrate condition and the completed repair procedure.

Application Scope

BW6-190 is used for injection-grouting repairs to leaking concrete structures, including sewage tanks, basements, subways, tunnels, culverts, utility tunnels and sanitary facilities. Drinking-water-contact use requires a separate suitability assessment and dedicated documentation for the product and repair system.

  • Concrete tanksLeakage grouting for concrete tanks, sewage tanks and suitable water-retaining structures. Confirm dedicated health-safety documentation before any drinking-water-contact application.
  • 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.

800-900%Foaming RateSupports crack-filling review where the material reacts with water or moisture and expands inside the leakage path.
90%Solid ContentProvides listed solids data for material comparison and grouting-work review.
120%ElongationHelps the reacted elastomer adapt to structural deformation inside compatible concrete leakage paths.
30-60 minCuring TimeHelps plan injection sequence, observation time and supplementary grouting during leakage repair work.

Product Features and Advantages

BW6-190 is designed for water-reactive leakage plugging, helping injected material expand inside concrete crack paths to fill voids, block water channels and form an elastic plugging body.

Reaction and Plugging Behavior

  • Hydrophilic Water ReactionReacts with water or moisture inside cracks and forms a polymer elastomer for leakage-path filling.
  • High Expansion RateThe official English technical sheet lists 800-900% foaming rate for water-reactive plugging review.
  • Microcrack PenetrationDesigned for concrete microcracks less than 0.2 mm and capillary pores.
  • Flexible Plugging BodyHigh strength and elasticity help the cured body adapt to structural deformation.

Construction and Site Review

  • Water-Curing CapabilityThe technical sheet lists curing in water and good fluidity for crack grouting work.
  • Weak Acid or Alkaline WaterThe material can react with weak acid or alkaline water without affecting the plugging effect according to the technical sheet.
  • Temperature-Insensitive CuringThe technical sheet lists curing at both high and low temperatures.
  • One-Component MaterialOne-component handling supports simpler field preparation with compatible pressure-grouting equipment.

Application Environment and Guide

Stable grouting performance depends on concrete soundness, crack continuity, water condition, needle layout and injection pressure. Review the application sequence and guide values before installation, and confirm final parameters with the latest TDS and project requirements.

Application instructions

Product data table
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 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.

Buyers can request the latest TDS, SDS, application guidance, packing information and project-specific grouting review before ordering.
