ATC Contractors Inc. and their trained professionals have in-depth knowledge and experience in the functionality, installation and performance of waterproofing, caulking and moisture protection systems for commercial, residential, and remediation projects. ATC Contractors Inc. is committed to provide a complete waterproofing system for your project.

Our crews have been trained to install the following types of systems provided by quality manufactures which include BASF, Carlisle, Dow Corning, Tremco, WR Grace, and York Flashing.

Sheet applied waterproofing system is designed to provide waterproofing protection for below grade foundation walls, slab, plaza decks and tunnels. The system consists of the self-adhering membrane, primer for surface preparation, a liquid membrane for detailing, mastic to seal termination points and drainage composites to protect the waterproofing system and provide water management.

Deck coating systems serve to protect the structure by waterproofing the concrete substrate while providing an attractive wearing surface. Deck coating systems meet the requirements of projects from condominium balconies to high traffic vehicular decks. The system consists of a durable, skid-resistant wearing surface and a waterproofing layer, which protects the above grade decks from the damaging effects of water and chlorine ion penetration, thereby preventing the water from penetrating the spaces below.

Bentonite waterproofing is a geotextile panel consisting of sodium bentonite clay encased between two layers of woven and nonwoven fabric. Bentonite clay in a hydrated state has low permeability and high resistance to chemicals. It is also self sealing when punctured or penetrated. Bentonite is ideal for property line or lagging applications.

Water repellent is a clear, filmless, penetrating product for virtually all above grade, vertical concrete, stucco, block and brick masonry. The treatment does not alter the color or texture of the surface, nor significantly affect the vapor transmission qualities of the substrate. The solution penetrates the substrate and chemically reacts to create a powerful barrier against water penetration. This barrier is resistant to ultraviolet and weather deterioration; however, it is necessary to reapply on a maintenance schedule every five to ten years.

Antigraffiti is a clear treatment for use on concrete, brick, concrete masonry units and natural stone. The treatment protects surfaces to allow easy removal of a wide variety of graffiti, including spray paint, permanent marker, ink, bituminous paints, asphalt sealers and other solvent or waterborne paints. Standard nonhazardous cleaners and low pressure waterblasting are sufficient removal methods for most graffiti.

Cementitious waterproofing is a unique chemical treatment for the waterproofing and protection of concrete. Structures can be waterproofed from the interior side of the wall by the process of osmosis; the crystalline formation migrates throughout the pores and capillary tracts of concrete even against strong hydrostatic pressure. The treatment is highly resistant to most aggressive substances. By preventing the intrusion of chemicals, salt water, sewage and other harmful materials, cementitious waterproofing protects concrete and reinforcing steel from deterioration and oxidation making it a good selection for elevator pits, sewage and water treatment tanks.
