CONTROLL INNERSEAL® - Deep Waterproofing Sealer

Controll Innerseal® is a crystallising deep waterproofing to protect concrete against moisture problems and strengthen the mineral substrate. The protection is open to diffusion and it is permanent.

Innerseal® is a non-toxic and colourless deep waterproofing that prevents water, acid rain, oils and other contaminants from penetrating. Thus, a proactive protection is formed against rebar corrosion, carbonation, cracking, efflorescence, weathering and algal growth.

Innerseal® forms insoluble crystals a few centimetres down in the concrete and becomes an integral part of the substrate. The protection is deeply seated and insensitive to external influences such as abrasion and impacts. Innerseal also has very good reinforcing properties in old and new concrete and mortar.

The treated surface does not become water repellent (hydrophobic) and thus can be coated with plaster or concrete, for example. If a water repellent surface is wanted, we recommend a combined treatment using ControllTopseal®. For stain protection on ground concrete floors, we recommend Controll SP Satin/Gloss.

For concrete surfaces with extra strict requirements to resist heavy wear and tear, chlorides or aggressive liquids, we recommend a combination treatment using Innerseal and Controll Innerseal® Plus(+).
