Adhesives, grouts, waterproofing membranes, trims and shower channels. Nobody chooses a tile for its adhesive — and yet the adhesive is what decides whether it is still there in ten years on a Caribbean terrace.
Butech — wet room, installation and trims
The house
Butech makes the installation systems of the Porcelanosa group: adhesive mortars, grouts, waterproofing systems, finishing trims, channel drains and ventilated façades.
One thing sets it apart from the six other firms: it does not serve Porcelanosa tile alone. Butech works with any make of tile. It is the one house in the group we sell to tilers who are laying something else.
The ranges
Adhesive, membrane, grout and trim are designed together — and Butech goes much further: pool drainage, substrate boards, cantilevered staircases and bathrooms delivered complete. The catalogues at the foot of this page carry the detail.

Adhesive mortars matched to the format, the substrate and the exposure. Large format and outdoor work call for classes that general-purpose products never reach.

Membranes and underlays for walk-in showers, shower rooms and terraces over occupied rooms. The invisible item that decides everything at five years.

Cement and epoxy grouts, in shades matched to the tiles. Outdoors and at a poolside, epoxy is not a luxury.

Corner trims, stair nosings, thresholds and shower channels. The visible parts of the installation system, and the ones that date a job.

Shower Deck for the walk-in shower, Pool Deck for the poolside, and the finishing gratings. On a pool meant to be finished in ceramic there is no prefabricated channel: the contractor has to design one on site. Butech turns it into a system.

The tiling substrate for ceramic: light, insulating, cut to size on site. It replaces built-up work where load is a problem, and it saves rebuilding a substrate just to tile over it.

The cantilevered stair structure, from the same technical catalogue as the rest of the system. A piece of architecture, ordered on the same purchase order as the tiling.

Why this brand here
On a Caribbean site, the installation system takes what the tile does not: heat, humidity, salt and slab movement.

The installation system ships with the tile. That is unremarkable elsewhere; here, it is what keeps a site from standing still for six weeks over one bag of adhesive.
