Composed of cement, graded quartz aggregates and selected additives, it stops both \u003cstrong\u003eactive and passive water pressure\u003c\/strong\u003e and is tested for use in contact with drinking water. The cured layer is durable, frost- and heat-resistant, efflorescence-free, yet remains permeable to water vapour so the structure continues to \"breathe\".\u003c\/p\u003e\n\u003cp\u003eVandex BB 75 is CE-marked under EN 1504-3 as a CC fine mortar for structural concrete repair (Class R3, ≥ 25 MPa) and bonds tenaciously to both horizontal and vertical surfaces, making it ideal for tanks, basements, retaining walls and water-retaining structures.\u003c\/p\u003e\n\u003ch4\u003ePrimary Applications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eConcrete and masonry surface waterproofing\u003c\/li\u003e\n\u003cli\u003eFoundations, slabs and basements\u003c\/li\u003e\n\u003cli\u003eRetaining walls\u003c\/li\u003e\n\u003cli\u003eWater tanks and reservoirs\u003c\/li\u003e\n\u003cli\u003eDrinking water structures\u003c\/li\u003e\n\u003cli\u003eActive and passive waterproofing  -  positive or negative side\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eKey Features \u0026amp; Benefits\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eResists both active and passive water pressure\u003c\/li\u003e\n\u003cli\u003eApproved for drinking water contact\u003c\/li\u003e\n\u003cli\u003eEfflorescence-free finish\u003c\/li\u003e\n\u003cli\u003eExcellent initial and final bond  -  works on horizontal \u0026amp; vertical surfaces\u003c\/li\u003e\n\u003cli\u003eFrost and heat resistant after setting\u003c\/li\u003e\n\u003cli\u003eVapour permeable  -  concrete still breathes\u003c\/li\u003e\n\u003cli\u003eReaction to fire: \u003cstrong\u003eClass A1\u003c\/strong\u003e (non-combustible)\u003c\/li\u003e\n\u003cli\u003eApply by brush, trowel or spray\u003c\/li\u003e\n\u003cli\u003eEN 1504-3 compliant  -  CC fine mortar for structural repair\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eTechnical Properties\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAppearance:\u003c\/strong\u003e Grey powder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDensity of wet mix:\u003c\/strong\u003e approx. 2.0 kg\/L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorkability at 20 °C:\u003c\/strong\u003e approx. 45 min\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetting time at 20 °C:\u003c\/strong\u003e approx. 5–8 h\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompressive strength (28 d):\u003c\/strong\u003e approx. 40 MPa (Class R3 ≥ 25 MPa)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBending tensile strength (28 d):\u003c\/strong\u003e approx. 6 MPa\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStatic modulus of elasticity (28 d):\u003c\/strong\u003e approx. 28 GPa (≥ 20 GPa)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdhesive bond:\u003c\/strong\u003e ≥ 2.0 MPa\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapillary absorption:\u003c\/strong\u003e 0.06 kg\/m²·h\u003csup\u003e0.5\u003c\/sup\u003e (≤ 0.5 kg\/m²·h\u003csup\u003e0.5\u003c\/sup\u003e)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChloride ion content:\u003c\/strong\u003e ≤ 0.05%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMixing:\u003c\/strong\u003e 25 kg + 4.5–6 L water; mix mechanically for 3 min\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCoverage\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressureless water:\u003c\/strong\u003e 3–4 kg\/m² (1.5–2 mm total)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater under pressure:\u003c\/strong\u003e 4–6 kg\/m² (2–3 mm total)  -  depending on water pressure\u003c\/li\u003e\n\u003cli\u003eMaximum 2 mm (≈ 4 kg\/m²) per single working cycle; multiple coats usually recommended\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003ePackaging \u0026amp; Shelf Life\u003c\/h4\u003e\n\u003cp\u003eSupplied in \u003cstrong\u003e25 kg PE-lined paper bags\u003c\/strong\u003e.
