Reinforced concrete channeling TEC

for drainage systems

The HM reinforced concrete pipes by PREFABRICADOS ALBERDI S.A. is intended, principally, for underground pipelines, road drainage, black water or sanitation, rainwater and surface water by gravity or, occasionally, pressurised. Given their inner steel reinforcement, they are ideal for bearing considerable loads generated by road traffic or significant coverings of soil. They can be classified according to their geometric shape and their manufacturing method. On one hand, there are the “bell and spigot” type pipes manufactured by radial compression (hereafter TEC) and “tongue and groove” or “halved joint” type pipes made by vibrocompression (hereafter TEM). At the same time, the European Directive 89/106/CE of Royal Decree 1630/1192 establishes that reinforced concrete pipes must have the CE marking complying with the provisions of the current standard in force, UNE EN 1916:2003. This is why at PREFABRICADOS ALBERDI S.A. we mark all our pipes accordingly.
