Concrete & Masonry Contractors Insurance Requirements

What property managers need to verify before hiring

Risk Level: high

Typical GL: $1,000,000/$2,000,000

Concrete and masonry contractors handle work that directly affects the structural integrity of your property — foundations, load-bearing walls, parking structures, retaining walls, and building facades. Defective concrete or masonry work can compromise building safety and is extremely costly to remediate. Property managers must verify that these contractors carry robust insurance because structural failures can result in catastrophic property damage, bodily injury, and extended building closures. Require concrete and masonry contractors to carry a minimum of $1M/$2M in GL coverage for routine work (sidewalks, flatwork, tuckpointing) and $2M/$4M for structural work (foundations, load-bearing walls, parking structures). Completed operations coverage is critical because concrete and masonry defects often take years to manifest — cracking, spalling, and water infiltration from defective work may not appear for several years after installation. For facade restoration and tuckpointing on multi-story buildings, verify that the contractor's policy covers work at heights and includes scaffolding operations. Masonry work generates significant dust and debris, so require dust containment measures when working on occupied buildings. If the project involves structural modifications, require the contractor to carry professional liability coverage and work under the supervision of a licensed structural engineer.

Recommended Insurance for Concrete & Masonry Contractors

Coverage Type	Recommended Minimum	Notes
Commercial General Liability	$1,000,000 / $2,000,000	Increase to $2M/$4M for structural work. Must include completed operations extending at least 5 years for structural concrete and masonry. Verify coverage for work at heights for facade work.
Workers' Compensation	Statutory limits	Required for all concrete and masonry contractors. Silica dust exposure is a growing regulatory concern under OSHA's silica standard (29 CFR 1926.1153). Employers' liability of $500K/$500K/$500K minimum.
Commercial Auto	$1,000,000 combined single limit	Concrete and masonry contractors operate heavy trucks and mixers. Verify coverage for vehicles operating on your property, including concrete pump trucks and material delivery vehicles.
Umbrella / Excess Liability	$1,000,000	Recommended for structural work and multi-story facade projects. Increase to $2M–$5M for large structural projects affecting building integrity.

Common Risks

Structural failure from improperly poured foundations or load-bearing walls

Cracking and spalling from incorrect concrete mix, improper curing, or poor workmanship

Water infiltration through defective masonry or failed tuckpointing

Property damage from heavy equipment (concrete trucks, pump trucks) on site

Silica dust exposure creating health hazards for workers and occupants

Damage to underground utilities during excavation for foundation work

Workers Compensation

NCCI class codes for concrete and masonry carry moderate to high rates, typically $5.00 to $12.00 per $100 of payroll. The physical demands of this trade (heavy lifting, working with power tools, scaffold work) result in relatively high injury rates.

NCCI Code	Description
5213	Concrete Work — Floors, Driveways, Sidewalks
5022	Masonry — Brick, Stone, Block Construction
5028	Masonry — Tuckpointing and Facade Restoration

Additional Insured Requirements

Require additional insured endorsements on the concrete/masonry contractor's GL and umbrella policies for the property owner and management company. For structural work, extend additional insured coverage to the project's structural engineer and architect. Completed operations coverage (CG 20 37) should extend at least 5 years for structural work. Waiver of subrogation on GL and WC is standard.

Frequently Asked Questions

Why does structural concrete work require higher GL limits?▼

Structural concrete work — foundations, load-bearing walls, parking structures — directly affects building integrity. A failure can result in partial or complete structural collapse, causing catastrophic property damage and potentially fatal injuries. Remediation costs for structural concrete defects routinely exceed $500K, making $2M/$4M GL limits prudent for this type of work.

How long should completed operations coverage last for concrete and masonry work?▼

For structural work, require completed operations coverage for a minimum of 5 years, though 10 years is preferred. Concrete defects such as improper mix design, inadequate reinforcement, or poor curing can take years to manifest as cracking, spalling, or water infiltration. The statute of repose for construction defects in most states ranges from 6 to 12 years.

What is the silica dust concern for masonry work?▼

Cutting, grinding, and drilling concrete and masonry generates respirable crystalline silica dust, which causes silicosis and lung cancer. OSHA's silica standard (29 CFR 1926.1153) sets strict exposure limits and requires dust controls, monitoring, and medical surveillance. Verify that the contractor has a written silica exposure control plan and uses appropriate dust suppression methods, especially when working in or near occupied buildings.

Should I require professional liability for concrete and masonry contractors?▼

Professional liability is recommended when the contractor is providing mix design, structural calculations, or engineering services as part of the project. For straightforward flatwork or tuckpointing performed to architect or engineer specifications, professional liability is not typically required. If the project involves any design-build elements or the contractor is making engineering decisions, require at least $1M in professional E&O coverage.
