Yes, CMU is the exterior clading mostly single wythe. It seems architects also like to extend masonry(brick & CMU) below grade as they do not want the foundation exposed. Therefore, I am concerned with the wicking you noted & environmental problems noted in Thread. Usually the details I am referring to the below grade reinforced CMU Stem Wall extends up to grade and the exterior CMU wall extends from there (often single wythe) which I tried to cover in my last post.

Rgerk Thanks for your reply.I did not intend for you to have to read between the lines. I posted a similar Thread and received no replies.

Known Code or Technical references would be helpful.

Please provide your recommendations and thought on these two subjects, as I often feel I am the only one concerned about these two problems. Therefore, masonry/brick ledge should be installed, which is more accepted for brick than CMU.

This joint often becomes unbonded from the foundation, losing the shear strength, and creating a crack which often causes water penetration in blowing rains. To me this does not seem to be good engineering practice and I would like to see waterproofing masonry below grade be addressed better by the Masonry Societies, due to the Environmental problems of algae, mildew, mold, staining, and efflorescence.Īnother problem I do not see addressed is CMU Walls being placed at Floor Grade without Masonry/Brick Ledges. The Brick Industry Association in their Technical Notes 28B – Brick Veneer does state, “If the soil immediately adjacent to the brickwork is not free-draining the brick wythe exterior should be waterproofed below grade.” However I have found nothing in the National Concrete Masonry TEKs concerning this and their details use CMU extensively below grade without waterproofing. Architects & Structural Engineers, often detail CMU/Brick being used below grade, without being waterproofed.(not talking about basements) This is especially disturbing when CMU stem walls are supported on spread footings extending to finish floor grade, when reinforced concrete would seem a better choice. easily adhered to the EPS of the ICF for stucco applications.I review Structural Drawings for a design/construction firm. Architectural detailing of the exterior may be enhanced with additional EPS molding, trim, window trim, etc. The success of the stucco application depends on proper installation, including details at openings, transitions, and the edges of the wall cladding. Traditional stucco, using a metal lath is directly applied to the ICF with the lath secured into the ICF fastening strips.

This eliminates the need to install an additional EPS layer over the wall assembly. ICF typically utilizes the thin-coat stucco method because it allows for quicker and less expensive installation than traditional stucco and EIFS.Īn ICF substrate is EPS which allows for the direct application of thin-coat acrylic stucco. Stucco cladding comes in three types: traditional stucco, exterior insulation and finish systems (EIFS), and thin-coat acrylic stucco. Other advantages of stucco include rot-, rust-, and fire-resistance. Stucco provides a weather resistant finish to the ICF. Stucco provides a beautiful exterior finish for ICF.
