Weisz & Sons

What Weisz & Sons does

Weisz & Sons Inc. is a family-owned general contractor headquartered in Bismarck, North Dakota, founded in 1976 and operating across Central North Dakota with a workforce of 51-100 employees. The company provides integrated heavy-civil and site-development services — including municipal water, sanitary sewer, and storm sewer piping, lift stations, excavation, site preparation, demolition, pre-cast concrete structures, sheet pile installation, dewatering, and road construction — to state, federal, county, and city agencies as well as commercial, industrial, healthcare, education, and residential clients. It has worked as both a general contractor and subcontractor on industrial and commercial projects for more than four decades.

The company's distinctive product line is Redi-Rock large-format precast concrete retaining wall blocks, each weighing approximately 2,000 pounds, available in gravity, reinforced (over 50 feet tall), freestanding, and hybrid configurations. Weisz & Sons holds exclusive retail rights for Redi-Rock in North Dakota and is the only Redi-Rock certified contractor in Central North Dakota, producing blocks locally at its Bismarck facility to allow design and color customization. The Redi-Rock of ND sub-brand operates as a wholly-owned adjacent subsidiary, with technical resources targeted separately at engineers and installers (design manual, block library, installation guides). The firm also sells construction materials — crushed concrete, crushed asphalt, blended base, fill dirt, and screened/unscreened topsoil — for pickup or delivery.

Weisz & Sons makes money through three channels: (1) project-based general contracting and subcontracting services priced per quote across municipal, civil, commercial, and highway/heavy segments; (2) Redi-Rock product sales plus professional installation services, with the company functioning as exclusive regional retailer and certified installer; and (3) construction materials retail and delivery. GTM is enterprise field sales driven by direct relationships with government agencies and private owners, supported by a content-marketing website, local SEO, phone/email contact, and community-based referrals — there is no digital self-serve channel, no API, and no software product. Pricing is universally project-specific and not publicly disclosed.
