A Wilmington, Massachusetts homeowner faced water intrusion through a deteriorated gasket between her precast concrete bulkhead and foundation. Rather than replacing the entire structure, Attack A Crack performed a bulkhead injection repair—a more cost-effective and durable solution.
Why Bulkheads Leak in Massachusetts
Bulkheads (precast concrete staircases leading to cellars) are notoriously prone to leaking — they are the second most common source of water in basement after rain, right behind foundation wall cracks. In Massachusetts, the cold joint where the precast bulkhead meets the foundation is sometimes positioned against the vertical first step rather than forming a horizontal floor seam, presenting unique repair challenges. New England’s clay-heavy soil and glacial till hold water against the joint, and each freeze-thaw cycle widens the gap further.
Our Bulkhead Sealant Injection Solution
The repair process involved two key steps:
- Sealing ports with hydraulic cement to ensure a watertight injection environment
- Injecting urethane bulkhead sealant to permanently seal the bulkhead joint — the same expanding foam technology we use in foundation crack injection
We selected urethane material because it expands to fill gaps and creates a flexible, waterproof bond that accommodates natural movement over time. Unlike surface-applied caulk or hydraulic cement (which fails within 1-2 New England winters), injection reaches every hidden void in the cold joint.
The Winter Repair Advantage
Performing repairs during winter months provides unexpected benefits. Frozen ground causes trapped moisture to expand and heave upward, creating the widest possible gap in the seam. The urethane injection fills this maximum space, and subsequent ground thawing compresses the seal even tighter, strengthening the repair further.
Outcome and Cost Savings
The client gained permanent protection against water seeping into her basement, eliminating concerns about stored items damage and providing lasting peace of mind — all for $1,800-$2,500, a fraction of the cost of bulkhead replacement ($5,000-$10,000+). The repair came with our lifetime guarantee. See our complete bulkhead repair cost guide for detailed pricing.
