Watertite alternatives for basement?

I plan on waterproofing a moldy basement with Watertite on the brick walls but it costs £65 / 5kg. Is there anything cheaper?

I believe tanking slurry is the wrong approach because the floor is made of stone slabs that are damp and I plan on sealing it with polyurethane or epoxy after filling any cracks. Replacing the floor isn't an option.

The walls aren't running with water, but mold will grow on the bricks.

"If its a cellar the floor and walls will need to be tanked.

It's a specialist job and a very approximate cost will be in the region of £6000
