Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.
Multi-purpose customized waterstops may also function as shuttering or crack-inducer for cold joints. Hydrophilic or "water-loving" waterstops are strips of rubber, modified with a hydrophilic agent (such as bentonite) so they swell in the presence of moisture to effectively seal concrete construction joints.
A joint replacing mortar with elastomeric sealant will absorb the compressive forces without damage. [4] Concrete decking (most typically in sidewalks) can suffer similar horizontal issues, which is usually relieved by adding a wooden spacer between the slabs. The wooden expansion joint compresses as the concrete expands.
Modern caulking compounds are flexible sealing compounds used to close up gaps in buildings and other structures against water, air, dust, insects, or as a component in firestopping. In the tunneling industry, caulking is the sealing of joints in segmental precast concrete tunnels, commonly by using concrete .
Sealant is a substance used to block the passage of fluids through openings in materials, [1] a type of mechanical seal. In building construction sealant is sometimes synonymous with caulk (especially if acrylic latex or polyurethane based) [ 2 ] and also serve the purposes of blocking dust, sound and heat transmission.
Penetrating sealants typically must be applied some time after curing. Sealants include paint, plastic foams, films and aluminum foil, felts or fabric mats sealed with tar, and layers of bentonite clay, sometimes used to seal roadbeds. Corrosion inhibitors, such as calcium nitrite [Ca(NO 2) 2], can also be added to the water mix before pouring ...

Organic sealants used for topcaulking in firestops may let go of the sleeve if it has conducted too much heat through to the unexposed side (as in the case of the fire test article, this picture). Plastic sleeves are usually removed after the concrete forms are stripped, as they contribute fuel to an accidental fire.
