How to seal gap between Travertine pavers and brick wall?

[geoffr]

We have just had laid new travertine pavers in our courtyard and on the path surrounding the house, and now wondering what to do for where they meet up with the house wall. Should the concrete/sand grout have continued all the way, should we use a silicon, or some other product? Perhaps a sealant that also helps with pest treatment? (There are no gardens or greenery near this edge, only pavers.) Currently when it rains water is collecting in the gap (under which is concrete) up against the house.

Thanks,

Geoff

Hi @geoffr,

Thank you for your question about how to seal the gap between your new pavers and a brick wall.

This gap has been left to allow for expansion and contraction of the materials, so you'll need to treat it like an expansion gap and use a flexible sealant such as Sikaflex 11FC Purform to cover the gap.

Start by cleaning out the gap with a vacuum to remove any loose material.

You can then use Sika 6mm x 50m Abelrod Gap Filler to fill the majority of the gap. This is a weather resistant foam filler that will allow for expansion and contraction and takes up much of the space, reducing the amount of silicone required.

When the Abelrod is in place, use painter's tape to mask off the wall and tiles. Once the bead of silicone has been applied, pulling the tape will create a nice clean line.

Once the tape is in place, apply your bead of Sikaflex 11FC Purform. The aim is to fully cover the gap and create a slight slope away from the wall. You can use one of the scrapers in this Paint Partner 4 Piece Silicone Scraper Set to strike off the silicone. After striking off the silicone, while the silicone is still wet, remove the tape to reveal a nice clean finish.

Let me know what you think and if you have any further questions, please don't hesitate to ask.
