Sealant Works

Sealant is a one-part, neutral-curing silicone exhibiting superior performance in applications where sealing openings in walls and floors are needed to control the spread of fire, smoke, toxic gases, and water during fire conditions.

Sealant reacts with atmospheric moisture to form a high-strength, durable seal that will adhere to most building substrates without the use of primers.



Flexicore offers a broad range of firestop products and solutions to help contain fire, smoke and toxic gases to the area of origin by sealing around penetrations and construction joints in fire-rated floors and walls. The fire protection products features sealants and intumescent devices.

Specialized in Sealant Application (Exterior & Interior)

Flexicore Construction Services also specializes in the installation of joint sealants to ensure a watertight seal is achieved for exterior and interior applications. Joint sealants are a critical component in all modern buildings, as they prevent water damage to both the exterior and interior of a building. Correct installation is imperative to ensure that the sealant does not fail, avoid leaks and extensive damage to buildings. Professional installation of sealants by our firestop experts is also essential so that the building remains aesthetically pleasing to both the owner and the public.
