SRO932 –Levelling Internal Dry Floors- Old Concrete

This recommendation is regarding the levelling of internal dry area floors prior to the installation of most types of floor finishes. It applies to aged concrete substrates but does not apply to internal wet areas. The concrete must be structurally sound (at least 20MPa compressive strength and at least 1.5MPa tensile strength). All remedial work to repair corroded reinforcement steel shall be completed prior to levelling.
Note: Some old concrete substrates may not be suitable for levelling cements.
