Concrete Repair Services for California and Nevada

Concrete Structural Repair

Courtney provides concrete repair services in the form of selective removal and replacement, patching, pinning, and epoxy injecting. Most customers call on us to provide these services on poured and precast structural concrete members. In some instances though, slab on grade concrete replacement is also performed as part of our scope of work.

Parking Structures

Courtney has built a strong reputation as an authority on concrete repair and restoration in parking structures. We have the ability to perform full and partial depth deck repairs, along with overhead surfaces and structural members.

Carbon Fiber Systems

In situations where it is called for, Courtney can utilize cutting edge technology like carbon fiber systems. Through the use of carbon fiber systems, Courtney can repair damaged columns, double tees, and structural slab concrete. With carbon fiber, damaged concrete members can often be repaired to standards that exceed original bearing design!

Spall Repair

Courtney also provides spall repair and prevention as part of our range of services. Spalling occurs when vehicular traffic, forklifts, or pallet jacks roll constantly over sawcut or formed construction/contraction joints in the foundation slab. The wheels of these heavy vehicles wear and/or break off the edges of the concrete joints, creating various problems. These problems will manifest themselves in hidden maintenance charges and costly worker injuries due to the unsafe nature of the joints. Courtney installs solutions to protect against future spalling and can also repair existing spalls and cracks. We use only quality materials to ensure the joint has good abrasion resistance and is rigid enough to protect the edges of the joints.

Epoxy Injection

In situations where concrete either needs to be repaired or waterproofed and excavation is not feasible
(e.g. a below-grade parking structure with expensive landscaping or hardscape over the area that would need to be excavated) Courtney offers negative side epoxy injection. If the concrete needs to be repaired, an epoxy can be shot through holes in the wall, spreading out over the target area. Where waterproofing is called for, a bentonite grout may be shot through holes drilled into the target structure, which then spreads out and gels upon contact with water to form a water-tight barrier.

Sack and Patch

A cornerstone of Courtney's concrete repair services is the sacking and patching of concrete. Whether it is cast-in-place, poured-in-place, or tilt-up panels, Courtney can sack and patch it to produce a finish ready for painting. Most of Courtney's sackers are veterans of over two decades in the trade, and their craftsmanship shows in the final product.

Grouting

Courtney has worked over the years with a number of owners and contractors to provide and install the structural grout found under column base plates, precast concrete units, keyed joints between hollow core units, and cavities of various precast/structural connections. Typically, a 20,000 PSI cementitious structural grout is used under structural units. In areas which are visible on wall surfaces, such as weld plate pockets, cavities, etc, an architectural patching material is used. Courtney offers a wide range of grouting services, including the application of chemical grout and urethane injections used for sealing cracks and joints in poured in place concrete foundation walls, concrete piping, containment tanks, water basins, and tunnels. These grouts are pressure injected into the cracks or voids where they then chemically react with water to form a closed cell foam or gel. This foam or gel then acts as a water-tight barrier, thereby sealing out unwanted water. Courtney can even utilize these grouts to stop flowing water through joints and cracks!

Tuck-Pointing

Lastly, Courtney also performs tuck-pointing, which is a restoration procedure in which deteriorated mortar is removed from the joints of brick, stone, terra-cotta, block, and other masonry walls. After removal of the old mortar, new non-shrink grout is installed. Tuck-pointing is utilized in situations where there are failed mortar joints (where the mortar is missing or disintegrating), cracked joints, or even in excessively soft mortar joints. It is extremely important that these joints be repaired through the tuck-pointing process to maintain the integrity of the masonry as well as provide a water-tight and aesthetically pleasing surface. Courtney strives to match the existing mortar in color, texture, and strength, without exceeding the strength of the masonry itself. To provide a water-tight surface that will last for years to come!
