Self-levelling floors are immensely popular because they are stylish and comfortable. Evidently, such eye-catching floors should be free of defects. Therefore, we developed the EPI Superbase self-levelling floor with a special crack-bridging membrane. This membrane absorbs 99% of all cracks, which means that with this solution you opt for security. This combination also reduces the impact sound by 15 dB!
What causes cracks in self-levelling floors?
The sleek look of self-levelling PU floors is due, among other things, to their superb adhesion to the substrate. Cracks in PU floors are often caused by cracks in the substrate. Movement in the substrate may also cause cracks in the PU floor. Fortunately, EPI Superbase self-levelling PU floors are slightly elastic. This elasticity prevents little cracks in the substrate from continuing into the PU floor. If a crack in the substrate increases, a crack or a fine line (vein) will develop in the PU floor.
Can you prevent cracks?
Often you can! The right preparation of the substrate is essential to prevent crack formation in most situations. When you have underfloor heating, you should always observe the heating protocol before installing the floor. In case you have a newly-built house in which the floors still need to settle, or if you come across dilatations (expansion joints) in your home, we recommend extra precautions.
Do you have a newly-built house or do you simply want to be sure? In that case, you should opt for an EPI Superbase cast floor combined with the EPI Membrane. Both contraction cracks and cracks due to settlement with a width of up to 2.5 mm will be bridged. This may not seem much, but it is substantial. Cracks due to contraction and settlement that exceed 2.5 mm are exclusively caused by building errors and natural disasters. With its static crack-bridging properties amounting to at least 2.5 mm, the EPI Superbase cast floor combined with EPI Membrane falls in the highest possible crack bridging category (A5).
Additional advantages
Standard EPI Superbase floors are already superbly strong and comfortable. If you opt for the extra EPI Membrane, your floor will be even more comfortable. As a Superbase floor with membrane reduces the impact sound by 15 dB, your floor will also amply meet the European standards for apartment floors. And finally: both the EPI Superbase cast floor and the EPI Membrane are fully solvent-free and contain for the most part natural raw materials and fillers, which benefits the environment. Your floor will last on average forty years and after that, the floor may be recycled to become a filler for a new floor!
