When leveling the concrete base, profile repair compounds or self-leveling mixtures are us,
The maximum permissible allowing you to create a perfectly smooth surface with a slight slope for natural drainage of precipitation.
The optimum slope of the surface should vary from 1% to 2%, ensuring natural drainage of precipitation and preventing the brother cell phone list formation of water accumulations on the coating. Correction of cracks and chips should be carri out using high-quality materials compatible with the base and the upcoming coating.
Monitoring the moisture content
Of the base is a vital stage of preparation before installing rubber crumb coating. Excess moisture can lead to material peeling, air pockets and this press release is also available on axa’s other defects that significantly ruce the service life of the coating.
Professional measuring devices, moisture meters, are us to detect moisture.
The permissible moisture level of a concrete base should not exce 4%,
The maximum permissible and for an asphalt base this indicator should not rise above 3%. If necessary, it is recommend to use professional dehumidifiers or wait for the surface to dry naturally.
Base requirements
Ideal surface flatness – do not exce 4 mm when test with a two-meter rail; Complete absence of cracks, potholes and other mechanical mobile lead damage; Properly design slope for water drainage – from 1% to 2%; Humidity level within standard values (4% for concrete, 3% for asphalt); Absolute cleanliness of the surface – absence of dust particles, dirt deposits, oil stains and other contaminants.
High strength of the base – not less
Than M200 for concrete surfaces; Temperature indicators of the surface and the surrounding air – not lower than +10°C during installation works; No precipitation at least 24 hours before the start of installation works.
Surface priming is the final stage of base preparation before laying the rubber coating.
For these purposes, specializ polyurethane primers are us, improving the adhesive characteristics of the surface and enhancing adhesion to the rubber coating.
