Repointing Brick and Stone Buildings


The Providence renaissance Hotel was a full scale renovation to a very historic façade. The exterior walls for this project were the originals from the construction of the Masonic Temple in downtown Providence. Phoenix Bay State was charged with the tasks of cutting and pointing the complete brick and limestone façade. The St. Astier product of Ecomortar G was used for the pointing of all limestone on the project. Also required were various repairs to the limestone façade in which St Astier’s NHL lime was used for varying crack repairs throughout the façade. Phoenix Bay State was very pleased with the products provided by St. Astier and the expedient service for delivery of materials which were critical for scheduling the project and beating the winter months. To date the installed materials and products have received accolades from the Rhode Island historical commission and the architects, engineers and contractors for the project, Hensel Phelps Management. Phoenix Bay State is very proud of the project and will be submitting the project for national historic restoration recognition.

This Porte cochere support wall needed a full repointing. The Wissahickon Shist stone also referred to as "Chestnut Hill stone" is found throughout the Philadelphia region.

This stone is a porous and soft sedimentary rock. Often ashlar blocks of stone and "Snecked rubble" coursing complemented the stone with evenly gauged mortar joints. In this case the "Ruled raised ribbon style" was used to create a more formal uniformity.


deGruchy Masonry, Inc. repeated the original use of a ruled raised ribbon pointing to match the balance of the house. Many times when the masons did this style of pointing it was highlighted in a white lime paint in the center of the ribbon. It is typical that only the base color of mortar remains and often the white highlight which has washed away from the acidity of rainwater does not get renewed.

Rarely seen is a rural farmhouse where the winning of stones from a quarry, many miles away, was then brought by cart to the site. Many rubble fieldstone buildings were simply "lined-out" in the wet plaster to make the building have the faux appearance that quarry-cut blocks of stone were used. Quarried stone used to build with is what is pictured here. Joint profile is the inverted “V.” Quakertown, PA. Color code Ecologic™ is DGM 50.

Joint Profile is the "Cobweb ribbon" style. Raised white material on top of a neutral background mortar was the method originally performed on this building in Philadelphia, PA. Color code-Base is Ecologic™ DGM 200. Ribbon- NHL 2 with fine white sand at a 1:1 ratio.



The Braithwaite Building of Southern Utah University in Cedar City, Utah had a total repoint using NHL.

Note- All the photos depicting Color code "DGM 50" is what can be used to replicate this off-white color that we have also called "Standard Cream Color" in the past. Everything required except water and mixing is already in a bag of Ecologic™ mortar. However, regular yellow mason's sand that meets ASTM C-144 specifications and NHL 3.5 could be mixed on site to also reproduce this color, or a shade very close to this color at a lesser cost. A mason can use yellow, brown, white or any other sand that meets ASTM C-144 specifications to achieve a similar hue to that of the sand color when using a Natural Hydraulic Lime as the binder.
