    Where to use RAPIDSTRONG EC 211: crystalline water barrier grout for tanks and pits

    RAPIDSTRONG EC 211 is a crystalline water barrier grout that is also elastomeric. It comes as two components, Part A and Part B, which are mixed and applied with a stiff brush on a damp surface. The crystals activate over time in the presence of moisture, which gives a self healing waterproofing layer for tanks, pools, pits and walls below ground.

    • Water tanks

      Brushed on the damp surface to form a water barrier.

    • Swimming pools

      Elastomeric, crystalline blended coat applied with a stiff brush.

    • Sewage treatment plants

      Two component grout with compressive strength above 30 MPa.

    • Lift pits

      Self-healing crystals seal fine cracks and capillaries over time.

    • Below-grade walls

      Applied on damp walls, then kept moist for 48 hours.

    For water tank leaks and lift pit seepage, this grout gives compressive strength above 30 MPa and complies with BS 1881. Its self-healing crystals seal fine cracks and capillaries when moisture is present, which suits below grade wall waterproofing too. Mix Part A and Part B to the specified ratio, brush on a damp surface and keep it moist for 48 hours.

    Armstrong Chemicals supplies RAPIDSTRONG EC 211 to sites across Telangana, Andhra Pradesh, Karnataka, Kerala and Tamil Nadu, including Hyderabad, Vijayawada, Bengaluru, Kochi and Chennai.

    Why RAPIDSTRONG EC 211 works

    • Self-healing crystals

      Crystalline chemistry activates with moisture over time and seals fine cracks and capillaries through crystal growth.

    • Elastomeric blend

      The elastomeric part adds flexibility, so the barrier combines strength with some give.

    • High compressive strength

      Compressive strength above 30 MPa gives the water barrier structural strength as well as flexibility.

    RAPIDSTRONG GROUT PU

    RAPIDSTRONG GROUT PU is an expansive, water-reactive, water-barrier polyurethane injection grout for free-flow pressure grouting. When it contacts water — including seawater and water containing slight acids or alkalies — it reacts quickly, expands into surrounding pores, cracks and narrow gaps, and polymerises within 36–48 seconds into a tough, highly adhesive solid. Non-toxic, non-pollutant, with no effect on potable water or marine life. Suitable for soil and abutment stabilisation, underground basements, retaining walls, rock areas, earth filling segments and structures exposed to waste water, industrial, chemical and sewage environments.

    RAPIDSTRONG GROUT VM 99

    RAPIDSTRONG GROUT VM 99 is a high-performance, solvent-free, two-component polyurethane-based duromer injection resin for the structural sealing and strengthening of cracks, joints and cavities in both dry and water-bearing concrete structures. Mixed A+B at 1:1, it gels in 25–30 seconds and achieves >75 MPa compressive strength and 70 MPa flexural tensile strength — tested to DIN EN 196 T1. Capable of curing down to -20°C, with 1–12× volume expansion on water contact depending on ingress, and re-injectable through existing hoses for permanent capillary sealing. Suitable for pressure injection and gravity feed. Industrial use only.

    ROOFEX

    ROOFEX is a high-performance penetrative crystalline waterproofing system. When applied to concrete, its active ingredients penetrate deep into the substrate and react with cement compounds and moisture — forming multiplied crystals that seal capillaries, pores and hairline cracks from within, transforming porous concrete into an impermeable mass. Effective against both positive and negative hydrostatic pressure. Four application methods: slurry coat, dry shake on fresh concrete, dry pack for joints and fillet sealing at construction joints. For water retaining structures, basements, effluent treatment and sewage plants.
