Concrete
• A mixture of cement, sand, aggregate, and water in specific proportions that hardens to a strong stony consistency
• Premixed concrete comes in many forms– Quick setting– Crack resistant – built in fiber –does not
require rebar – High strength– Comes in 40, 60 & 80 lb bags
Cool Looks in Concrete
Steps to pouring a concrete pad
1. Mark the area with stakes and mason’s string.
2. Remove the sod at least 6” deep and 6” past the outside lines
Steps to pouring a concrete pad
3. Fill the area with 2” of compacted base. Tamp with a tamper to prevent settling
• Some people do this after they build the form
Build and install forms made of 2 X 4 lumber set on edge
• Position them so the inside edges line up with the strings, then drive 1 X 3 stakes next to the forms at 3' intervals.
• Attach the stakes to the forms with nails for easy removal.
• Use a carpenter's level to make sure the forms are level to one another (from side to side), but fall at least 1/8" in 10' along the walk.
Isolation Board
• Glue an isolation board (expansion joint) to steps, the house foundation, or other permanent structures that adjoin the walkway.
Rebar
• Reinforce the walkway with rebar or welded wire mesh
Control Joints
• Mark locations for control joints (to be cut by a groover later) by tacking nails to the outside faces of the forms, spaced roughly at 3 ft. intervals.
Mixing
• Mix concrete according to package instructions
• Consistency should be like mashed potatoes.
• Make sure you mix all the way to the bottom
Pouring
• Pour the concrete in the forms.
• Use a screed board to level the concrete.
• Run a spade along the inside edges of the form, then rap the outside edges of the forms with a hammer to help settle to concrete.
Finishing Concrete
• Smooth the surface with a wood float
• Precut control joints at marked locations using a trowel and a straightedge.
• Run an edger against the forms.
Texture or Color
• Brush concrete with a push broom or stamp with a form
• If you want to stain the concrete, do it now
• Cover with plastic and allow it to cure for 5-7 days
