CAULKING AND SEALANT
Missing or deteriorated sealant within building expansion joints and at the perimeter of masonry openings (windows, doors, etc.) is often the source of moisture entry into the wall system. Caulk is designed to seal joints or cracks, and to protect them from water, dust, insects, air, and noise. Sealants are used to help joints with expansion and contraction, and adhesives are used to prevent joints from moving.
Tuckpointing can be defined as the removal and replacement of mortar between stone, block, or brick. The objective is to replace the existing failing mortar with new mortar to match the original texture and color as closely as possible. Once mortar has been placed within the joint it is then tooled. Tuckpointing is also known as repointing or just pointing. When done properly, tuckpointing will provide a strong, sealed joint that will help extend the life of the building.
When excess moisture within brick or concrete block freezes, the result often times is the cracking, spalling, or disintegration of these units. This is due to the expansive nature of confined moisture as it freezes. Deteriorated brick or block would be identified and replaced with new units that closely match the original in size, color, and texture. Repair of conditions that expose the masonry to abnormal moisture is recommended to keep the same deterioration from occurring in the future.
Waterproofing is the formation of an impervious barrier, which prevents water from escaping wet areas to dry areas. Internal areas that are waterproofed consist of shower recesses, bathrooms, flooring, and indoor swimming pools. Outdoor areas that are waterproofed consist of split face block (rock face), brick, block, planter boxes, balconies, decks, retaining walls, and outdoor swimming pools. Waterproofing can be applied to a variety of surfaces.
Masonry walls effectively resist moisture when properly designed and constructed. Excess moisture may develop within the wall system if an effective means of relieving the absorbed moisture is not used.
The result of this can lead to the corrosion of masonry anchors, lintels and relieving angles, water damage to interior finishes, and the creation of mold or mildew on the non-masonry surfaces.
When flashing and new lintels are installed, we demo out 3-4 courses of brick, remove the old lintels, install a new lintel in the area, then we put flashing over the lintels, anchor a piece of termination bar, and caulk tops of terminations bar and sides of flashing to ensure a water tight seal. We also install weap ropes for drains before brick is replaced..
With the use of our pressure washing system, we can clean many types of building surfaces and remove years of dirt created from winds and traffic.
Through the use of chemicals, buildings can be restored close to their original luster after they have been acid washed
