QPro Concrete Sleepers can be cut to achieve specific sizes when required. It is recommend that you only use equipment that is designed to cut concrete and reo. It is also best practice to treat the exposed reo with either cold galvanised spray or solvent based bituminous paint.

Why the Reo? It has been calculated that the initial 350mm of subterranean post bear the load of a retaining wall. Beyond this point the purpose of the reo is to bind to the concrete footing. Depending on the wall height the size and number of reo will vary.

QPro Concrete Sleepers are manufactured to a strength of no less than 40MPA and contain reo bars. All Qpro Concrete sleepers are 200mm high x 75mm thick and come in various lengths.

Reinforced concrete elements crack wherever the tensile stress in the concrete reaches the tensile strength of the concrete. This stress in the structure can occur at any location and may be caused by a number of factors, including applied loads, restrained shrinkage, temperature changes (including early-age cooling), support settlement and so on. Flexural cracks, caused by bending, occur at the tensile face when the fibre tensile stress reaches the tensile strength of the concrete. It should be noted then that the result of hairline cracks in a concrete member would not be detrimental its overall integrity provided the minimum reinforcement requirement has been met. This requirement ensures that a lightly loaded member has an adequate reserve of strength if unexpected cracking occurs and applies to tension members, as well as flexural members.
