Boise's Specialist for Stabilization
If water is getting into your basement, the problem isn't the concrete—it's hydrostatic pressure. Water in the soil pushes against your foundation walls and up through the floor. We install systems that capture and remove that water before it becomes a problem.

Why Boise Basements Get Wet
The Treasure Valley has several factors that conspire against dry basements:
- High Water Table: During irrigation season (April-October), groundwater rises dramatically. The water has to go somewhere—and it pushes up through your slab.
- Clay Soil: Clay doesn't drain. Water accumulates against your foundation walls, creating intense lateral pressure.
- Cove Joint Seepage: The "cove joint" where your floor meets the wall is the weakest point. Water enters here first.
- Floor Cracks: As concrete ages, cracks develop. Rising groundwater finds every crack.
Interior vs. Exterior Drainage
There are two fundamental approaches to basement waterproofing:
Exterior Waterproofing
Involves excavating around the entire foundation, applying waterproof membranes, and installing exterior drain tile.
- Pros: Keeps water out entirely, protects the wall itself.
- Cons: Extremely expensive ($15,000-$40,000+), disruptive (destroys landscaping), not always possible (decks, driveways, additions block access).
Interior Drainage (Our Specialty)
Manages water that enters by capturing it at the floor-wall joint and routing it to a sump pump.
- Pros: 50-70% less expensive than exterior, no yard disruption, works in any weather, effective for hydrostatic pressure.
- Cons: Doesn't stop water from touching the exterior wall (rarely a structural issue).
Our recommendation: For most Boise homes with hydrostatic pressure issues, interior drainage is the best value. We reserve exterior work for specific situations like crumbling walls or structural concerns.

Our Interior Drainage System
We install a complete water management system:
- 1. Perimeter Trenching: We cut a narrow channel around the basement perimeter, just inside the walls.
- 2. Drain Tile Installation: Perforated pipe is laid in the trench, surrounded by washed gravel. Water enters the pipe from all directions.
- 3. Wall Vapor Barrier (Optional): A dimpled membrane can be installed on walls to direct any wall seepage into the drain system.
- 4. Sump Basin & Pump: All drain lines converge at a sump basin. A cast-iron pump with battery backup ejects water outside.
- 5. Concrete Restoration: The trench is filled with fresh concrete, flush with the existing floor.
What to Expect: Cost & Timeline
- Partial System (1-2 walls): $3,000-$6,000
- Full Perimeter System: $8,000-$15,000
- Sump Pump Only: $1,500-$2,500
Timeline: Most basements are completed in 1-2 days. The concrete needs 24-48 hours to cure before heavy use.

Sinking Garage Stabilization
A homeowner in the area noticed a 1-inch separation between their garage floor and the foundation wall. Our diagnostic confirmed the home was built on uncompacted fill soil near an old irrigation lateral.
