Specifying Broomed Exterior Concrete Surfaces

featured1

As a safety requirement, all exterior concrete surfaces must have a slip-resistant surface. The most common method for this is specifying a ‘broom finish.’ But, is that all there is to it? Specifications must also satisfy owner requirements for appearance, flatness, texture, as well as drainage.

Epoxy types: A guide for specifiers

Ideally, a bonded anchor should be installed into concrete of known compressive strength. Engineers who specify epoxy anchors also specify the compressive strength to ensure the epoxy can achieve its published bond strength.  If the compressive strength or overall integrity is unknown, they sometimes require field testing of the embedded anchor to determine if the concrete is good enough.

Epoxy types vary widely, and specifiers need to note such attributes as nozzle time, gel time, load time, sag, cure time, and chemical resistance—each property will affect what makes the product ideal for the intended application. When searching for the proper epoxy to specify, it is important to note there are three general classes—pure epoxy, polyester resins, and epoxy acrylates—that break out in different ways with respect to properties and performance.

During the medieval period, complex Gothic structures were built from drawings that communicated a designer’s overall vision without detailing specific means of construction. Master craftsmen translated designs into buildable structures using simple tools available at the time. Now, in some respects, the construction industry has come full circle.
