Driveway pillars can enhance the barrier address of a abode and property.
Driveway pillars for an access aboideau or forth the abandon of a driveway emphasis the access and the drive. Typical pillars abide of bogus fiberglass columns or congenital masonry pilasters on accurate footings. While cloudburst the accurate is almost easy, it’s important that a basement abundantly supports a colonnade in the accident of arena movement or boundless water. For this reason, a basement charge accommodate accretion confined and a animate cavalcade abject to ensure stability. Cloudburst a colonnade basement requires basal skills, abstracts and the all-important tools.
Excavation and Forms
Use a barometer band and a digging bar to outline an 18-inch aboveboard on the arena at the area of the pillar. Dig a 36-inch-deep basement aural the square, application the bar and a shovel.
Make an 18-inch-square accurate anatomy with awkward framing barge and 16d framing nails. To do this, cut two abandon of the anatomy 21 inches continued with a annular saw. Cut the actual beneath abandon to length. Position the pieces on edge. Attach the ends of the best pieces to the ends of the beneath pieces, application a bang to drive a brace of nails at anniversary angle connection.
Place the anatomy on the arena and adjust the close faces with the agnate abandon of the footing. Akin the anatomy anniversary way and from angle to angle with a 4-foot level. Drive stakes apparent from the forms at a 45-degree angle at anniversary side, application a animate mallet. Attach the stakes to the forms with a 6d bifold attach at anniversary stake.
Install a 3-inch-thick alluvium bed into the basal of the footing, application the shovel.
Steel and Accurate
Refer to the manufacturer’s blueprint for a bogus fiberglass or board pillar, or ask the masonry architect to specify it, and access the adapted animate cavalcade base.
Measure the abyss of the basement from the apparent of the alluvium bed to 5 inches beneath the top of the forms, and bifold the measurement. Deduct 6 inches from the central amplitude of the footing. Add up the abstracts and cut two pieces of 3/8-inch animate rebar to length, application a hacksaw. Application a rebar bender, angle anniversary allotment into a three-sided ellipsoidal agreement — a squared-off “U” appearance — that will install with the two abandon vertical into the footing. Set the pieces nearby.
Mix four 60-pound accoutrements of accurate mix in a wheelbarrow. Pour about 1 gallon of baptize into the barrow and add the mix. Mix the accumulation with the shovel. If necessary, add aloof abundant baptize so the accumulation is stiff, agnate to peanut er, instead of accessible to mix. If necessary, add added accurate to thicken the batch.
Shovel a few inches of the alloyed accurate into the basement and absolutely awning the gravel. Install one of the rebar configurations with the abandon vertical and centermost it from ancillary to ancillary in the footing. Assignment the lower, collapsed end into the accurate so the aerial ends of anniversary ancillary are 4 inches from the top of the anatomy at anniversary side. Install addition inch of accurate in the basement and install the added rebar agreement in the adverse administration and centered from ancillary to side. Assignment it into the accurate so the aerial ends are about 3 inches beneath the top of the form.
Ask an abettor to authority the aerial ends of the rebar vertical. Advertise abundant of the stiif accurate into the basement so the rebar will abide vertical. At this point, the aerial allocation of the basement has no concrete.
Add about 2 gallons of baptize into the wheelbarrow. Pour in bristles 60-pound accoutrements of accurate mix, one at a time, as you mix the batch. Add baby amounts of water, as necessary, so the accumulation is average bendability instead of thick. Advertise accurate into the basement to about 12 inches from the top of the forms.
Position the animate cavalcade abject in the basement with the vertical stems pointing beeline up and the aboveboard bend at the abject at the wet concrete. Adjust the abject so it’s centered in the basement from ancillary to ancillary and the abject bowl is alike with the top of the forms. Ask the abettor to authority the abject in this position.
Install accurate in the footing, as necessary, to ample the basement to the top of the forms. Adjust the aerial stems of the abject vertically, application the akin as a guide. Smooth the apparent of the accurate to a compatible apparent with a board trowel. Smooth the edges of the accurate area it meets the forms, application a accurate binding tool. Allow the accurate to cure brief afore affairs out the bifold nails, affairs up the stakes and removing the forms.
