Quick and watertight floor repair

In basement rooms, damp, uneven and leaky floors are often found instead of the desired storage space.
Conventional solutions are usually very costly. They involve many work steps and are above all effort-demanding, time-consuming and therefore expensive. The self-levelling and watertight floor compound weber.tec 932 is a labour-saving solution and is quite easy to process. It is suitable for layer thicknesses from 5 mm to 30 mm in one go as bonded system. This enables particularly low construction heights to be achieved. The floor surfaces are open to pedestrian traffic after only a few hours.

Simple & safe to the goal

  1. 1. Substrate preparation
    Check the substrate for sufficient load-bearing capacity. Remove adhesion-impairing particles and substances.

  2. 2. Flatness check and calculation of layer thickness and material requirements.

  3. 3. Floor/wall connection
    Create a groove with the watertight mortar weber.tec 933 in the angles between floor and walls.

  4. 4. After priming, apply the 2-comp. reactive and quick-setting waterproofing coating weber.tec Superflex D 24 on the pre-said connection area and also on the floor along the walls in a width of approx. 20 cm.

  5. 5. Application without a groove at floor/wall connection
    After the waterproofing layer has dried through, install the self-bonding acoustic insulation foam strip weber.floor 4960 along the walls.

  6. 6. Priming of mineral substrates
    Apply the specific primer weber.prim 932 P. It is mixed with water in a ratio of 1 : 3 parts by volume and brushed intensively on the substrate up to saturation.

  7. 7. Priming of brick substrates
    Use the alkaline horizontal damp-proof barrier weber.tec 941 as blocking primer. It is used full-surface in 2 coats undiluted and intensively brushed onto the substrate.

  8. 8. Mixing of the self-levelling and watertight compound
    Mix with water until a completely lump-free mortar is obtained.

  9. 9. Pouring of the self-levelling and watertight compound.

  10. 10. The material is poured from one lane to another one "wet-in-wet".

  11. 11. weber.tec 932 is applied without primer on the overlapping area covered with weber.tec Superflex D 24 on the 20 cm wide stripe along the walls.

  12. 12. Check of layer thickness
    weber.tec 932 is applied in one layer in thicknesses of 5 - 30 mm, depending on requirements and substrate. On brick floors the minimum layer thickness is 15 mm.

  13. 13. Surface treatment
    After application up to the required layer thickness, smooth the surface of weber.tec 932 with a flat rake. In case of layer thickness ˃ 20 mm, it is recommended to de-aerate the surface with the wobbling bar weber Schwabbelstange.

  14. 14. Ready, levelled and flat surface after completion of levelling and waterproofing works.

  15. 15. The finished surface can be walked on after approx. 3 - 5 hours; after final hardening, it is open to full load after 7 days and also fully abrasion-resistant, i.e. directly usable as a wear layer and resistant to chair castors.

  16. 16. Protection against moisture and radon gas
    In this case, the whole floor surface is waterproofed with weber.tec Superflex D 24 in a dry layer of 4 mm thickness prior to application of weber.tec 932. After drying, weber.tec 932 is applied in one layer of at least 10 mm thickness without primer.
