MM Systems Products

Aesthetics, innovation, and durability are the hallmark of MM's line of floor, wall, ceiling, and roof joint cover systems. Engineered systems include features that are ADA compliant, fire-rated, no-bump, and heavy-load designs capable of thermal, seismic, and wind-sway movement.

Waterproofing Expansion Joints are designed to prevent water infiltration while accommodating structural movement. Ideal for roofs, plazas, and wet areas, they protect building interiors from moisture damage, mold, and deterioration—ensuring long-term durability and performance in demanding environmental conditions.

High-performance joint sealing systems engineered for the demanding conditions of parking structures, stadiums, and other exposed environments. These systems provide waterproofing, fire resistance, ADA compliance, and accommodate thermal expansion, shear movement, and seismic activity—ensuring long-term durability, structural integrity, and occupant safety in open-air applications.

In areas prone to seismic activity, expansion joints are crucial in allowing the building to flex and move to help avoid structural damage. Some seismic considerations may require +/- 100% movement in any and all directions—leading to our Seismic Specialty solutions. Our engineered joints handle thermal movement and help absorb seismic forces safely.

Life Safety Fire Barrier Systems are engineered and tested to current standards and code requirements. Ratings include 2,3 and 4-hour endurance. Seismic fire barriers accommodate multi-directional movement including longitudinal shear. Vertical and horizontal systems include chase and plenum designs. Factory approved transitions insure continuity of rating throughout the structure.

Insulated Vapor Barriers (IVB) is an engineered solution for thermal and vapor management in structural openings 1 inch (25mm) or larger. It resists temperature changes and vapor transmission, making it ideal for use in brick, block, concrete, and cladding systems.

Engineered and fabricated to exacting tolerances, architectural metalwork by MM is available in a variety of materials and finishes. Column covers, beam wraps, light coves, sunscreens or your unique designs become signature elements of your project. Choose from unlimited Kynar 500® / Hylar 5000® color coatings.

ADA compliant grating and trench cover systems. Decorative gratings offer an architectural alternative to traditional cast-iron gratings and are ideal for pool and plaza decks, green spaces and fountain surrounds. Removable access covers allow access to in-floor electrical and refrigeration services. Optional trench liners provide an exit path for moisture.
