A Stronger and Durable Landscape Curb for Minnesota
Curb Creations of MN has perfected this process to make sure you have the most durable and attractive Concrete Edging for your home or business.- Portland Cement - One of the most widely used types of basic building materials in the United States. It is a sustainable material that is durable, dependable, and suitable for a variety of concrete construction applications. It is formulated to provide optimal strength characteristics meeting ASTM C 150 Type I-II.
- Sand - Washed concrete sand is used because it contains light gravel aggregate for a stronger curb. Mason sand is too fine and does not contain a light gravel aggregate.
- Assurance Admixture - Assurance is a neutral, biodegradable, lubricating, chemical additive designed to reduce shrinkage and cracking that can occur in low slump concrete mixes. The plasticizing properties of Assurance also contribute to easier placement and extrusion of the concrete, while intensifying colors, textures, and workability.
- Air-Entrainment - This is a chemical found in Assurance. Millions of microscopic air cells per cubic foot. These air pockets relieve internal pressure on the concrete by providing tiny chambers for water to expand into when it freezes.
- Cable "Re-Bar" Protection - A 1/8 inch hot dipped galvanized steel cable goes through the curb as it is being extruded. The cable increases the tensile strength of the curb by 1700 PSI. The cable improves strength and durability and minimizes shifting and/or separation during freeze/thaw cycles. The Zinc coating on the steel cable helps to inhibit corrosion, Our steel cable is 1700 PSI compared to stainless steel at 1300 PSI.
- Exact Amount of Water - To produce workable slurry on surface of curb and to maintain “0” slump for extrusion precision as well as strength.
- Experienced Curb Machine Operator - The operator is consistently putting pressure against the curb machine creating stronger compaction. The operator is also making sure the correct amount of concrete is being extruded through the mold to produce maximum mass and strength.
- Skilled "Finish" Craftsman - Trowel out any imperfections and then compact the landscape curb with firm, commanding strokes thus producing a higher PSI.
- Control Joints - Are cut approximately half way through the curbing every 2 – 3 feet to allow expansion and contraction from seasonal changes.
- Cure and Seal - Solvent based sealant. Aids in proper curing of concrete curb as well as protection from color fading and staining. For best results a solvent based concrete sealant should be applied every 2 - 3 years.
