Filling Holes in Tumbled Travertine

22 January 2019


To fill or not to fill, when it comes to travertine - that is the question! Our outdoor stone specialist, Gary Bazzana, explains why our customers usually fill in the holes in the travertine when using travertine outdoors.

Travertine is a freshwater sedimentary stone composed of calcite which is usually formed at the mouth of hot springs or in limestone caves. It naturally has open holes that once held little bubbles of trapped gas.

The most popular finish for Travertine to be used outdoors is the tumbled finish.

The tumbled finish has a higher slip rating than the filled and honed tiles, favoured for indoor use.

Tumbled Travertine pavers and tiles are imported with the holes in the stone still open, known as “Tumbled and Unfilled”.

Classic Travertine Tumbled – Left Unfilled

To achieve the tumbled finish, the stone is placed into large open rounded machines resembling top loader washing machines filled with pebbles. The machine vibrates and this moves the tiles or pavers around in the pebbles to pre-age them giving them a more organic and tumbled look rather than a square edge.

More often than not, customers choose to fill the holes with grout after installation rather than see those holes fill with dust and organic matter such as leaves or grass clippings.

In areas prone to dampness, mould can quickly develop in the unfilled holes.”

To fill the holes in the tumbled travertine, we recommend using a pre-packaged grout in a complementary colour to the stone.

We do not recommend grouting travertine with a sand/cement mix as this will discolour quickly – the coloured grout option will work best.

Choosing a grout colour a shade or two lighter than the travertine, will help to brighten the overall appearance of the project. A colour choice closest to the stone will draw the least amount of attention to the holes in the stone.

Classic Travertine Tumbled – Filled on Site

In choosing the first-grade stone the hole sizes will be smaller and hole frequency lower as a general rule.

When it comes to filling the travertine, the first-grade stone will mean less fill, less time, and less money spent on the job.
