• the sealant can be particularly well dosed in terms of its amount to be used.
• the sealant can be used very sparingly. Because the wall is lower than one
• outside wall of the cover ensures that the wall defines an overflow height and therefore the amount of sealant that seals the joint is normalized.
• sealing compound flowing over the wall does not flow into the area outside the cover. This ensures that the sealant does not contaminate the manufacturing facility. If at least one of the ladder per joint breaks out and the pedestal is dimensioned so that it is at the
• Joining process projects into a subspace, this ensures that the joint is completely immersed in the sealant. If the pedestal and / or the cover is wedge-shaped or pyramid-shaped, an entry of the gas bubbles into the sealant is thereby avoided during the joining. Under certain circumstances, gas bubbles could lead to the joint or a gap between the sealant, joint and pedestal possibly becoming moist, and thus such a small gap may be a place for first corrosion at the joint.
