SERVICES
We re-level all settled structures from garages to small homes, to skyscrapers, to arenas; we do it all. All our work is done by hand, and so we don't need to use costly and heavy machinery to re-level your structure. We provide a free onsite estimate, and will recommend the best solution to fit your needs.
​
Footings, foundation walls, machinery bases and other heavy objects that have settled may benefit from permanent steel piling. Pipe piles or "jack" piles are driven by using the weight of the structure as counterweight and hydraulically jacking lengths of steel pipe into the ground. Once in place, simultaneous lift is applied on a number of piles to provide even lift back to correct elevation.
Mudjacking or shallow pressure grouting. Airport tarmacs, warehouses, shopping centres, school floors, highway slabs, driveways, patios or sidewalks...for any concrete slab that has settled without major breakage it is frequently more economical to lift and stabilize than to replace. Lightweight, fluid cement is pumped at low pressure through small holes to "float" the concrete up with a minimum of disturbance.
Tie-back anchors are frequently required on lifting and stabilization jobs, particularly on houses and retaining walls built on fill. We have also had to repair bulging walls that were not adequately reinforced. Our standard tie-back consists of a steel casing, a "Dywidag" rod as tendon, an injected, high strength concrete "knob" as anchor, and plate hardware for attaching to walls.
Epoxy crack injection (also referred to as epoxy injection) is an extremely effective and reliable concrete crack repair method, used exclusively for the repair of poured concrete foundation cracks, for the structural repair of same, to fix basement leaks, and to prevent poured concrete foundation cracks from leaking in the future.
Underpinning is a highly effective method of arresting and correcting foundation settlement, involving excavating beneath a strip footing at regular intervals and installing driven, bored, or excavated concrete piers to a competent bearing layer. In many cases, piers are installed such that the footing may be jacked against them to correct settlement of the structure.
Deep pressure grouting into weak soil zones many feet below grade can permanently solve settlement problems and provide very even lift at the surface. The process will usually benefit perimeter zones beyond a building and prevent the drop of sidewalks, steps, parking and landscaping adjacent to the building.
Mechanical lift, when required, is accomplished by the use of specialized equipment with which we 'pull up' a piece of concrete, rather than excavating underneath and pushing. Our mechanical lifting procedures are generally used in combination with pressure grouting or mud-jacking under the slab. Mechanical lift is especially beneficial when a floor is unevenly loaded with machinery bases, steps or divider walls.
