    Look at a snap shot of major innovations introduced by CONVERGENT which has transformed the industry as we know it.
    2001

    Introduction of the PENTRA® brand

    A line of specialty products for distribution. Launch of Pentra®-Sil Lithium Silicate Densifier, replacing sodium and/or potassium silicate densifiers. This set a new standard in the flooring industry for hardening, densifying, and sealing concrete.
    Also introduced: Patented Pentra®-Sil (244+), an advanced hardener, densifier, and sealer offering protection against moisture, salt, and efflorescence.
    2003

    Introduction of Pentra®-Guard (HP) and Pentra®-Guard (EXT)

    • Pentra®-Guard (HP): The first "Guard", a micro-film-forming inorganic hardener/sealer hybrid, providing enhanced wear resistance, chemical resistance, and stain protection for industrial floors.

    • Pentra®-Guard (EXT): The first exterior-grade hybrid, offering similar performance benefits for pavers and other masonry substrates in outdoor applications.
    2010

    Introduction of Pentra®-Sil (HD+C) and Pentra®-Finish (HG)

    • Pentra®-Sil (HD+C): A patent-pending, membrane-forming hardener that meets ASTM C309 standards. Functions as both a curing agent and a hardener.

    • Pentra®-Finish (HG): A patented, high-gloss, “non-whitening, non-streaking” inorganic hybrid treatment for concrete, tile, and terrazzo.
    2010

    Introduction of LisoTop

    A range of penetrating sealers designed to provide long-lasting water and oil repellency for natural stone, marble, granite, and concrete surfaces.
    Easy to apply, these sealers penetrate deeply without altering the appearance of the surface, allowing it to breathe while protecting it from stains, moisture, and dirt.
    Ideal for both interior and exterior use, they help preserve the natural beauty and durability of mineral surfaces.
    2014

    Introduction of Transil

    A lithium-based hardener specially formulated for concrete road surfaces.
    It penetrates deeply and reacts with free lime to form a crystalline structure, densifying and permanently hardening the surface.
    Ideal for roads exposed to heavy mechanical stress, it enhances abrasion resistance, reduces dusting, and significantly extends pavement life.
    2016

    Introduction of Pentra®-Sil (HW)

    A dual-component product: mixing Part A with Part B creates an advanced micro-bonding stain protection treatment for stone, masonry, and concrete.
    Its reactive and water-repellent properties protect porous surfaces from water-borne staining, efflorescence, dirt, and grime buildup.
    2021

    Introduction of LisoFloor

    A range of potassium silicate-based hardeners and protective coatings designed for easy application without the need for machinery.
    These products penetrate deeply into concrete, increasing hardness and durability while offering effective protection against dusting, abrasion, and water ingress.
    Suitable for new and existing concrete floors, they enhance surface strength and longevity with minimal effort.
    Between 2022 and 2025

    Introduction of Rock-Pro

    As a company rooted in research and innovation for concrete surface protection, we’ve introduced various hardeners and performance-enhancing products.
    Rock-Pro: A sodium silicate-based hardener and protective treatment designed to deeply penetrate concrete, improving surface hardness and long-term durability.
    Between 2022 and 2025

    Introduction of Silico Surfacer

    Based on colloidal silica, this product is generally used for large surfaces and follows a 3-step system: curing, densifying, and polishing—often using a power trowel.
    This technology is based on the oldest known hardener and densifier system in the world.
    Between 2022 and 2025

    Introduction of CG PA Polyaspartic Resin

    Epoxy resin is well known for creating high-resistance flooring, but it comes with major drawbacks—strong fumes, flammability, and health risks.
    Our CG PA polyaspartic resin delivers the same high durability with very low odor and a safer application process.
    It can be used on its own, with CG PA Color (our polyaspartic-based color resin), or enhanced with Pentra®-Color Hard or decorative color chips for a customized finish.
    2025

    Introduction of B-Mortar

    This versatile repair mortar is designed for all types of cracks and holes.
    Compatible with all our product lines and completely resin-free, it is easy to apply and offers excellent adhesion and durability.
    Ideal for various substrates, it restores surface integrity without compromising the performance of subsequent treatments.
    2026
