String Course
Description

Cast stone string courses available in five standard designs to help add contrasting architectural elements. String courses can also be produced to individual requirements. String courses are also known as a band course.

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:

  • Suitable to breakup brickwork, they can be designed to be either flush within the wall or to project slightly.
  • Can be used in conjunction with other architectural dressing, such as plinth courses and quoins.
