All the components that make up all the rainwater gully are sealed together by elastomeric gaskets that guarantee absolute tightness of the sewerage system, thus eliminating the risk of soil pollution due to possible loss of rainwater with high oil content.
WATER TRAP AND SLUDGE DEPOSIT
The rainwater gully body is provided with an element that ensures the smell trap by creating a hydraulic guard, so it is avoided the emanation of odors from the sewer drain in the gully area. Also ensure a generous storage volume of sand and mud which is washed by rain, avoiding so the entry in the sewage system.
RESISTANCE TO CHEMICALS AND ABRASION
The PE rainwater gully has an extremely high resistance to abrasion and aggression of chemical substances existing in the rainwater.
RESISTANT AND ROBUST
TeraPlast rainwater gully has all the advantages provided by plastics: sturdiness, shape stability, flexibility. As it is well known flexibility of plastic products ensure their long-term behavior much better than those rigid (concrete) because it performs much better in successive loads of traffic load.
EASY INSTALLATION AND ECONOMIC EFFICIENCY
All components are lightweight and can be handled by one person, so the installation of the rainwater gully is simplified and fast, without additional costs generate by other machine. In addition to these advantages must be taken into account the easier transport and with a much lower cost.
Expected life of these types of rainwater gullies is 50 years.
