NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) January 1, 202 4 Volume 2 Joints shall not be filled by pouring in a thin or liquid mortar.
E.Pointing (new construction) and Tuck Pointing (raking out and repointing).
1.Pointing. Tool the face joints with a pointing tool before the mortar sets, as approved by the Engineer. Avoid smearing the masonry surfaces with excess mortar forced out of the joints. For joints not pointed when the masonry is laid, prepare the joints for poin ting by following the tuck pointing procedures. There will be no separate payment for this work.
2.Tuck Pointing (Repointing). Repoint the joints in masonry where indicated on the Contract plans or directed by the Engineer. Use an Item 705 -21 Type M, S or N masonry or mortar cement, tuck pointing mortar (or a specially designed one) with the same or weaker strength than the ori ginal mortar, as approved by the Engineer. Remove soft, loose, cracked and deteriorated mortar to a minimum depth (measured from the wall face) of twice the average joint width, and remove all deteriorated mortar beyond the minimum depth, as ordered by the Engineer. Do not damage the masonry durin g the removal process. Clean all contamination from the prepared joints. Prior to repointing, flush with water and leave all surfaces to be re -mortared in a dampened, surface dry state. Pack the prepared joints in layers with mortar that closely matches the original color and texture, allowing each layer to become thumb -print hard befo re the next. Use at least two layers when the joint depth is twice the joint width. Apply a final layer thickness that does not exceed the joint width. When the final layer is thumb -print hard, finish with a pointing tool that recreates the original joi nt shape, or as approved by the Engineer. Perform pointing when the ambient temperature is 40°F or above, and the masonry is frost free. Avoid recessed joints that hold water. After the mortar sets, clean all mortar and cement stains from other surfaces. In direct sunlight, keep the newly pointed masonry moist for at least 3 days. In shade, moisten 2 to 3 times a day for at least 3 days.
F.Drawings. The contract plans show the general character of the masonry. Prior to the beginning of any work, the Contractor shall prepare and submit for the approval of the Regional Director, three sets of detail plans for all dimension masonry shown on the plans .
