Portico
Application

The cast stone porticos can be easily incorporated to transform any doorway into a grand entrance. It is often possible to combine individual elements in order to create a completely new design.

Foundations to be designed by others, to suit site conditions and loadings. All materials other than stonework to be supplied by others, consult technical literature for further details.

Description

From their beginnings as a shelter from the elements, they’re now a popular feature often associated with Georgian, Neo-Georgian and Georgian revival style projects. A portico is sometimes called a porch.

Available in 10 different styles, consult manufacturers literature for further information.

Combine with columns to achieve desired height. Consult manufacturers literature for further information.

Material:

- Haddonstone (Semi-dry cast limestone):

High quality semi-dry cast stone, consisting of over 50% limestone aggregate. With a surface texture similar to Portland Stone, Haddonstone is regularly used alongside or as an alternative to natural stone.

- TecStone (wet cast limestone):

High quality wet cast stone, comprising over 60% natural limestone aggregate. Denser than the Haddonstone material, TecStone is acid etched as standard to provide an attractive appearance similar to a finished natural stone. Designed to meet demanding performance criteria and can incorporate structural reinforcement and cast-in fixings. TecStone is the preferred material for architectural projects where structural performance is required.

Features and benefits:

  • Highest quality semi-dry cast limestone.
  • Straightforward installation.
  • Bespoke designs are available.
  • Suitable for existing and new builds.
  • Return entablature components are available for 90° external corners.
