Basement Repair

INDICATIONS OF BOWED BASEMENT WALL:

• Horizontal cracking
• Stairstep cracking
• Bowed inward

The affected area is excavated. Specially designed braces are positioned in the basement and the wall is jacked back to its original position. Rebar is then inserted vertically from the outside into the cells of the block. The wall is then pumped full with grout from the outside.

The braces are left in place while the wall "cures" for approximately 4-7 days.

Foundation Repair

INDICATIONS OF SINKING FOUNDATION:

• Stair step cracks in blocks and bricks
• Misaligned windows and doors
• Interior cracking
• Uneven floors

The foundation is excavated and steel piers are strategically placed to provide the needed lift. As the structure is lifted, concrete grout is injected into the void created under the foundation. The purpose of this grout is to evenly distribute the load, add additional strength, and prevent erosion and pest infestation.

After the structure has been repositioned, the piers are permanently locked off, filled with concrete and the foundation is backfilled to a rough grade.

Quad Power

THE QuadPower™ PIERING SYSTEM IS THE PERMANENT SOLUTION!

• Stairstep cracks in blocks and bricks
• Chimney pulled away from house, tilting, or leaning
• Doors or window sticking
• Cracked interior walls

A-1's patent-pending QuadPower™ Piering System provides four times the surface area at the base of each pier, producing a load bearing capacity that is superior to competitive methods. Our QuadPower™ system has been engineered and tested to provide a cost effective and permanent solution in more varied soils and more challenging conditions than any competitive system.

The foundation is excavated and mechanical lifting brackets are permanently installed onto the foundation. Our components parts are manufactured using heavy gouge structural steel and must meet A-1's exacting standards. QuadPower™ piers are driven below the unstable soil into stable strata. The lead section of each pier detects the resistive force of the stable soil and, at a secure depth, automatically flairs the base of each pier, quadrupling its surface area. The structure is then hydraulically lifted to a point of optimal practical recovery, and the piers are permanently locked in at the practical recovery position. The shaft of the pier is filled with hydraulic cement, and concrete grout is injected into the void created beneath the foundation to evenly distributed load and provide additional strength.

If you are looking for a cost effective solution to your most challenging piering and foundation stabilization projects, A-1 Concrete Leveling's QuadPower™ Piering System offers you the most powerful piling piering system on the market.
