Concrete manhole base with cradle new

DESCRIPTION AND USES OF THE PRECAST CONCRETE MANHOLE BASES

Base modules

The precast concrete manhole bases with cradle by PREFABRICADOS ALBERDI S.A. are cylindrical on the inside, with concrete water pipe-work already executed and joined monolithically to the floor. This concrete cradle or half-pipe perfectly redirects the effluent and has a coat of coal-tar epoxy, depending on the aggressiveness of this effluent, always at the request of the customer. At the same time, it has flexible gaskets that ensure a watertight connection with the pipelines and the other modular pieces.

Another of the fundamental specifications of the concrete water cradles or half-pipes is that, due to their monolithic nature, the leaks that may occur between them and the vertical wall are prevented. In addition, unlike those of origin plastic, the prefabricated concrete bases for manholes can resist the sun perfectly while maintaining the properties they had before being installed on-site.

At the same time, every base module also consists of various pins to facilitate transport, loading and unloading and the positioning of these pieces on-site, providing greater speed, agility and safety in the execution.

The methods used in the manufacture of the concrete manhole bases and the use of high quality materials fully guarantees the quality, durability and function of our precast concrete manhole bases.

The base modules by PREFABRICADOS ALBERDI, S.A. are manufactured according to the layout of every sewer, and different inlet and outlet angles with different water sheet shoulder measurements can be combined.

Due to Royal Decree 1630/1192 entering into effect through European Directive 89/106/CE on the provisions for the free movement of construction products, it is established that the elements that make up the manholes or inspection chambers must carry the CE marking complying with the provisions of the current valid standard, UNE EN 1917. This is why at PREFABRICADOS ALBERDI S.A. we mark all our bases accordingly.
