Plastic Masonry Shims

Plastic Masonry Shims

Solid plastic shims are able to align, cushion, and relieve stress while stone materials are put in place and mortars are set.

For stone masonry, plastic masonry shims can establish temporary or permanent joint spacing.

When used for stone panel cladding, shim panels align both vertically and horizontally. Additionally, masonry shims can be used to relieve stress while mortars set.

The advantage of utilizing plastic shims for terracotta is that brittle materials can be temporarily cushioned with shims to prevent damage before being fixed or sealed into place.
