Specialized substrate & shower preparation
Drypack and shower preparation, built to the millimetre.
Silveira Drypack prepares what the finish depends on: scratch coat, waterproofing membrane, drypack mortar beds and sloped shower bases — packed, screeded and checked so the tile that follows sits flat, drains properly and lasts.
Working with contractors, builders, renovators and tile professionals in Toronto, Ontario.
What we do
Four services. One discipline.
Every layer we build is a substrate for someone else's finish, which is why each one is set out, checked and detailed on its own terms.
- 01
Scratch Coat
A keyed cement mortar base coat applied over lath or a prepared substrate to create a flat, mechanically sound surface for the layers that follow.

- 02
Membrane
Waterproofing membrane work for wet areas — applied over prepared substrates so water is managed at the correct layer of the assembly.

- 03
Drypack
A stiff, low-water sand and cement mortar bed, packed and screeded to a precise plane or slope as a substrate for tile and stone.

- 04
Shower Drypack
Shower floor and base preparation: drypack mortar packed and screeded to consistent slope toward the drain, ready for the finishing trades.

The Silveira approach
Preparation decides the finish.
A tiled shower is an assembly, not a surface. Each layer — the substrate, the keyed base coat, the waterproofing plane, the mortar bed — has a job, and each one depends on the accuracy of the layer beneath it.
Once tile goes down, the substrate is no longer accessible. A bed that is out of plane, a fall that flattens near the drain, or a membrane detail rushed at a corner cannot be corrected afterwards without opening the work back up.
That is why our scope stops where the finishing trade begins. We concentrate on the layers that get covered, and hand over work that is measured, checked and ready to build on.
Process
Assess. Prepare. Build. Finish.
- 01
Assess
Review the drain, substrate, framing, heights and access, and confirm what the assembly needs before any material is mixed.
- 02
Prepare
Set the reference points and protect the area — lath, screed rails, drain height and perimeter lines established before packing begins.
- 03
Build
Pack, screed and compact the mortar to the required plane or slope, then detail corners, curbs and edges by hand.
- 04
Finish
Check the plane and fall, clean the area, and hand over a substrate the tile setter or finishing trade can build straight onto.
Proof of work
Real work, before it disappears under tile.
Floors, corners, drains and transitions documented on site — shaped by hand and checked before anything covers them.
On the job
Fresh drypack, straight from the site.
Short walkthroughs from recent projects — full-floor mortar beds screeded flat and ready for the next trade.
