Mechanical Research & Design, Inc. Bulkheads and Large Isolation Barriers

Mechanical Research & Design, Inc. is a leading designer and fabricator of Bulkheads and Large Isolation Barriers for the construction, underwater construction, nuclear, and environmental services industries. We specialize in both standard and engineered-to-order (temporary and permanent) pressure barriers, specialty gates, and valves. Our vast working experience in custom sealing and restraint systems allows us to provide countless solutions, helping our customers have peace of mind when worker’s lives are on the line. Our products can be found as safety barriers protecting construction sites, in tunnels, drifts, open channels, near water intakes, as nuclear containment structures for fuel storage or reactor maintenance, and deep underwater in some of the most sophisticated diver and ROV installations on record. We design our SEALFAST® Bulkheads and Isolation Barriers in configurations for low, medium, and high pressures, to optimize for weight and cost. Our SEALFAST® Inflatable and Mechanical Elastomers can seal in most new and aged existing infrastructure, as some of our greatest success stories come from installations involving cracked or spalling concrete. Our products are perfect for steel lined, cast iron, concrete, brick and mortar, and even rough cut stone surfaces — we have seen it all. We design for the real world of uneven, non-parallel walls and irregularly shaped tunnels.
