Where to Buy W. R. Meadows

Sheet-applied waterproofing membranes are prefabricated self-adhering or loose-laid sheets that form a continuous barrier against water on below-grade and horizontal surfaces. They are used in commercial construction on foundation walls, plaza decks, and tunnels to prevent water intrusion.

Below-grade waterproofing consists of membranes, coatings, and drainage products applied to foundation walls, slabs, and other subsurface concrete to prevent water intrusion and hydrostatic pressure damage. Products include sheet membranes, fluid-applied coatings, and bentonite systems used on basements, tunnels, and below-grade structures.

Dampproofing consists of asphalt- or bitumen-based coatings applied to below-grade foundation walls to resist moisture migration under non-hydrostatic conditions. It is used in commercial construction to reduce dampness transfer through concrete and masonry substrates.

Expansion joint systems are assemblies of metal cover plates, seals, and elastomeric materials that span structural gaps to accommodate movement from thermal expansion, seismic activity, and settlement. They are installed in floors, walls, ceilings, and roofs of commercial buildings, parking structures, and bridges.

Sodium bentonite clay waterproofing supplied in panels, sheets, or granular form that swells on contact with water to seal below-grade concrete surfaces. Applied to foundation walls, slabs, and blindside applications to resist hydrostatic water intrusion.

Curing compounds are liquid membrane-forming coatings sprayed onto fresh concrete to retain moisture during hydration and reduce surface cracking and dusting. They are used on slabs, pavements, and structural concrete to promote proper strength development, and may be resin- or wax-based per ASTM C309 or C1315.

Liquid-applied topical or penetrating treatments that protect concrete surfaces from moisture, chemicals, staining, and abrasion. Applied to interior floors, exterior slabs, and decorative concrete to reduce dusting and extend surface life.
