What are the advantages of slipforming curb over hand forming?

• Slipformed curb is stronger: Low-slump concrete is stronger than the high-slump concrete used in hand pouring.
• Slipformed curb is faster: You get more production with the same number or fewer people, resulting in lower price to the end user.
• Traffic patterns are diverted for a shorter time due to the speed of completing the project; thus, the traveling public (the taxpayer) is happier.
• Low-slump, air-entrained concrete is more resistant to salt and slag deterioration.
