    Water tanks made of concrete/steel reinforced concrete or otherwise, steel or other material
    prefabricated concrete tanks,
    Drinking water tanks,
    Tanks with wall movement due to expansion and contraction

    TYPICAL SPECIFICATIONS

    HYPERDESMO®-2K-W shall be applied on internal surface over the coat of primer AQUASMART®-DUR. The product shall be certified for potable water (O.T.E.C institute in accordance to the EU guideline 98/83/EC), having excellent chemical and mechanical resistance. The cured membrane shall have tensile strength >20 MPa, adhesion to concrete > 2 MPa and water absorption <0.5%.

    SURFACE PREPARATION

    All waterproofing treatment performances are based on the soundness and suitability of the surface. The surface shall be cleaned from all loose materials, oil, laitance and any other construction debris. The surface shall be free from spalling and unevenness, if in case the surface is very uneven, then it shall be resurfaced using polymer modified repair mortars

    APPLICATION OF PRIMER

    AQUASMART® -DUR shall be mixed well and applied using roller /brush over the prepared RCC surface as a primer that shall be self-cured.

    JOINT FILLING

    Joints and inner angles should be treated with polyurethane based sealant HYPERSEAL®-EXPERT-150 or HYPERSEAL®-25LM-S.

    APPLICATION OF WATERPROOFING MEMBRANE

    HYPERDESMO® -2KW shall be applied in one single coat over horizontal surfaces and in multiple coats on vertical surfaces. HYPERDESMO® -2KW is certified for usage in direct contact with potable water and needs no protection layer. In case of protection from high chlorinated water the coating shall be over coated by AQUASMART® –TC 2K POOL PROTECT.
