KARMAT telescopic covers for sewage chambers are made of the highest quality plastics resistant to high and low temperatures. These materials are enriched with high-quality additives that significantly increase the durability and resistance of finished products to discoloration caused by weather conditions. We offer telescopic covers with increased pressure resistance up to 3 tons (30 kN), confirmed by tests carried out by an external laboratory. Telescopic covers allow for easy adjustment and their setting to the ground level during assembly. They easily compensate for surface movements that change their level in winter conditions.
