The base is where a column meets the ground or plinth, and it carries a lot of the visual weight of the whole feature — a mismatched or roughly finished base undermines an otherwise well-detailed column. Unitex Column Base profiles give builders and renderers a lightweight, precisely formed transition piece that installs cleanly at the foot of a column and finishes as part of the same render system as the rest of the facade, without the weight or on-site shaping that a masonry base demands.

What’s in the Column Base Range

The range covers five distinct base profiles, each available in two standard diameters to suit different column widths. Most series are offered in both round and square (SQR) options, so the base profile can match whichever column style is being used elsewhere on the project — a traditional round column or a more contemporary squared one. Several combinations are held as stock items, with a smaller number of round and square variants supplied as bespoke where a less common size or profile combination is needed. One profile in the range includes an additional ring detail, giving a more decorative, layered transition where a column meets its base for projects wanting extra articulation at that junction.

Built for Render Integration, Not a Standalone Finish

Like the rest of the Uni-Shape® range, column base profiles are designed to be coated with Unitex base coat render and finished with the chosen texture and topcoat finish, so the base reads as a continuous part of the column and the facade rather than a separate applied piece.

Why Builders Choose Lightweight Column Base Profiles

A masonry or precast column base has to be formed, cured and finished on site, and getting a clean, sharp transition at the base of a round or square column by hand takes real skill and time. A pre-formed EPS base profile arrives dimensionally consistent and ready to fix in place, cutting both the labour and the skill dependency out of that detail. With multiple diameters and both round and square options held as stock, most standard column installations can be matched without waiting on a bespoke order.

Ordering Column Base Profiles for Your Project

Stock diameters and profiles can be ordered directly against the plans. Where a project needs a size or round/square combination outside the standard stock range, the Unitex technical sales team will confirm dimensions and lead time before quoting, the same as any other bespoke Uni-Shape® item.

Column Base profiles sit alongside Uni-Shape balusters and the wider Uni-Shape® Profiles & Columns range, all finished using the same Unitex base coat render, texture and topcoat system for a consistent facade.

Frequently Asked Questions

What diameters are Column Base profiles available in? The range is available in two standard diameters across each base series, covering the most common column widths used in residential and light commercial facades.

Can I get a round base for a square column, or vice versa? Most series in the range offer both round and square profile options, so the base can be matched to the column style being used. Where a specific combination isn’t held as stock, it can be produced as a bespoke item.

Do column base profiles need to be rendered? Yes. They’re designed to be integrated into a render and texture system rather than left exposed or painted directly, so the base finishes consistently with the rest of the column and facade.
