Reducing slabs

DESCRIPTION AND USES: REDUCING SLABS

Precast concrete reducing slabs are horizontal parts of reinforced concrete that consists of a polypropylene step forming a stairway to allow access to and maintenance of the pipeline.

In addition to joints with elastomeric sealing gaskets, every reducing slab also has various pins to facilitate transport, loading and unloading and the positioning of the concrete manhole bases on-site, providing greater speed, agility and safety in the execution.

The methods used to manufacture these precast concrete reducing slabs and the use of high quality materials fully guarantee the quality, durability and function of these products. These pieces will have two mat reinforcements in the form of a slab that guarantees adequate mechanical resistance.

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 1917:2004. For this reason PREFABRICADOS ALBERDI, S.A. marks all of its pipes with the CE marking by means of dispatch notes.
