General Notes

-A qualified engineering professional should be used to determine all structural requirements.

-All instructions should be read prior to commencement of any work.

-A listing of recommended products is located at the end of this section.

-Installation should only be attempted by qualified personnel with the necessary tools and experience to undertake this type of work.

-This work may require the prior approval of local building officials and be affected by local building codes

-All grouts, mortars sealants, etc. should be installed in accordance with the manufacturer's instruction unless noted otherwise.

Installation: Prior to installation ensure that the surface that is to receive the column is clean, level, and structurally sound. Once you ensure that all the above conditions are met, begin installation by installing the stone base (see diagram 1.1). Apply a layer of mortar to the surface that is to receive the base. This mortar will allow for leveling of the column base and help in anchoring the column to the substrate. When fitting all column pieces together, a ¼” joint should be maintained. The halves of the column base should be anchored together using traditional pin attachment methods as shown in diagram 1. 1. Attach the pieces together using strap anchors and masonry screws (Tapcon). Do this by laying the strap anchor across the joint line, and screw into the stone using your Tapcon screws as shown on 1.1. It is very important to attach your stone to the structural support to keep the column pieces from moving. Do this by attaching strap anchors to the stone using masonry screws on the sides with no joints as shown on 1.1. Flip the anchor up in an L position and lay it flush up against the pole. Attach the anchor to the pole using metal screws. We do not recommend infilling the column with cement. Using pins to anchor the pieces to one another vertically is an essential part of installing a column correctly. Pins are usually made from 1/4” dia 3”-6” lengths of rebar or all thread; you can also order specialty made pins from a steel manufacturer if desired. To install pins you will simply drill 4 places into the stone at your desired depths. The holes will need to be symmetrical in placement as shown in diagrams 1.1 and 1.2. Place a good amount of epoxy into the holes to insure anchorage. Place the pins into the holes. Then take the shaft piece that will be placed on top of the base pieces and drill holes at the exact same locations the pins were placed on the base pieces. Be sure before drilling that your marks for drilling are lined up with the existing pins. Fill the newly drilled holes and the joint surfaces with epoxy then apply the shaft to the base by slipping the holes onto the pins. Be sure to use spacers on all joints to keep your 1/4” space. Joints should be rotated per piece layout as shown on diagram 1.2. Repeat the process above for all remaining pieces. Water should not be allowed to sit on the top of the columns, or drain into the shaft hole. Care should be taken to cover and seal the top of the column if it is to be exposed weather and elements. When grout joints abut other surfaces or when the column is subject to movement a sanded caulk should be used in lieu of grout to eliminate grout cracking. Sealer should be applied to the product in accordance with manufacturers instructions.
