We restore or replace elements of brick, stone, and terra cotta through Masonry Restoration. During the process, some intricate pieces may need to be recast to match existing work, while stone elements are patched and molded with special products to match existing stones, make up, profile and color.
The concrete restoration process involves making and locating delaminated and/or deteriorated concrete. We properly remove, prepare the cavity, and patch with the proper materials depending on the use of the structure.
Tuckpointing is the process of removing deteriorated mortar joints between the brick, CMU and stone.
The correct mortar is chosen to match the strength of the existing mortar so as not to cause stresses that will cause it to fail. Samples are performed on site in order to match the existing mortar color.
The use of carbon fiber is a solution to add stability and repair cracked or bowed concrete structural elements. Carbon fiber is bonded to an area with epoxy. Once the carbon fibers are bonded with the epoxy, the system becomes stronger than steel.
This process involves installing product into joints of a structure, thus prevent water from entering the building, as well as providing aesthetics/cleanliness.
Sealant joints deteriorate over time and if not maintained, will cause deterioration of the structural elements inside, which cannot be seen.
Epoxy injection is a structural repair, not a waterproofing technique, used to re-establish the integrity of a cracked beam or column, haunch or etc.
Specially designed injection ports are inserted into holes drilled into the existing crack. Epoxy is then injected into the holes from a hose. The hose is then moved up to the next port when the epoxy reaches it from the previous one. This process is continued along the full length of the crack.
Waterproofing is the process of applying/installing product prohibiting the infiltration of water through a wall into an occupied space.
Damp Proofing is applied/installed for “shedding” water from a surface. Damp Proofing does not guarantee prohibited infiltration of water.
Waterproofing/Damp Proofing can be applied on vertical below grade walls or horizontally between a topping slab and the structural deck.
Traffic and Pedestrian Coatings
This process prepares an existing concrete surface in order to apply a coating. Coatings are applied as a remedy slippery surfaces, protect the existing surface from the elements, and repair surface deterioration or, simply protect the surface.
Products used to coat concrete surfaces are epoxy resins with sand, methyl methacrylate with sand, polymer modified cementitious products and urethanes.
Water Repellants (Clear Sealer)
Many products claim to repel water on concrete; however, effective water repellants have a solid hydrophobic material suspended in a solvent or other carrier, which carries it into the concrete or masonry then evaporates. These products contain siloxane or silane.
Cleaning of the surface prior to application of water repellant is always highly recommended prior to application. Performing a small test area is highly recommended to ensure the sealer does not change the appearance to the existing substrate.
