Mosque Ablution Room - In-Situ Terrazzo

Before: Wooden Floor

We started with a wooden floor and raised pedestal featuring stools. The channel (on left of picture) falls away to various drainage points and is used for ritual washing. Careful planning was followed to ensure all our work lined up with existing tile joints and was even across the floor.

Screeding

In order to bond terrazzo onto the existing tiles, we used a bed of 35-50mm sand cement with a scratch coat. The walls, channel, plinth all required accurate screeding both horizontally and vertically. The strips were set in after screeding was completed

Installing Divider Strips

Solid aluminium strips were strategically placed along the wall and floor all aligned to safeguard against cracking. Divider strips and control joints can be researched more in NBS M41 specification also BS 8204-4.

Laying In-Situ Terrazzo

Mixed and laid by hand, Premfloor operatives lay the channel first using the bespoke cementitious terrazzo mix. In-situ terrazzo has to be installed by experienced progessionals and mixed correctly in order to maintain a uniform colour and aggregate distribution across the project.

Grinding & Polishing Walls

We protected the wall with strong correx affixed to ultra low tack adhesive. The limestone tiles were interfaced to the terrazzo, both finishing at the same depth. Vertical grinding was done with specialist 110v equipment and powerful air movers to remove the majority of dust from the area into a HEPA filtered system.

Grinding & Polishing Floor

The floor was ground by hand with a series of carborundum and diamond discs. As the floor is regularly exposed to water, it was specified to finish on a coarse grit of 80 with a matt finish anti-slip sealer.
