To get the repair job done well, a concrete contractor must have a full collection of home tools. Because no one waits for concrete, the right tools will discern between a good pour and a possible catastrophe. Most of the critical devices are simple and do not require a large investment. Lower the cost of leasing payments and the wasted time loading up and returning the machines by owning them. Any specialized equipment is more costly and is only worth the expense of the instruments is needed. Otherwise, renting particular items as you need could be cost-effective.
Screeds – For Large Concrete Repair Spaces
When you pour it, screeds are long, straight, rigid tubing or boards that smooth and approximately level wet concrete. Screeds, such as those used for constructing concrete bridges, are available in various sizes and can also be project-specific. For hand-screeding, when you flatten the concrete, the screed must be longer than the concrete form’s width so that it can travel along the top edges of the state.
A direct straight piece of dimensional timber, a 2 x 4, suffices as a screed for several smaller works, including sidewalks, garages, driveways, and patios. Commercial screeds are also available and are mostly ‘sheets’ of aluminum with a shape identical to a 2 x 4. Marketers sell them in lengths used, such as 6 feet, 8, ft, 10 ft. Some consumer screeds have leveling vials added to them to make the slabs easy to level.
Specialty Concrete Repair Tools
Additional specialty resources may be required for contractors providing specialty services or accommodating enormous work.
Grinders and polishers.
Several walk-behind and handheld equipment for polishing and grinding concrete surfaces can help contractors deliver countertop production or floor polishing.
While troweling by hand is still the standard, walk-behind trowels are becoming increasingly common for extensive surfaces.
Screeds for power.
Contractors building pervious concrete (which causes water to seep through) use motor-powered roller screeds that stretch out and compress the concrete mixture mechanically for correct compaction.
When touching the concrete, rubber gloves are vital. Concrete includes contaminants that may irritate the scalp, as well as admixtures. In concrete, cement absorbs moisture from the skin and can cause significant damage. After several years of treating concrete with exposed skin, there are also cases of life-time workers requiring amputation. Skin disorders are a leading cause of missed work time for concrete workers, according to OSHA.
There are several kinds of contractor-grade gloves for concrete work. Others provide optimum durability, and others are equipped for optimum puncture resistance. Materials vary from solid natural latex or neoprene (synthetic latex) to rubberized cotton or nylon cloth blends. You can also buy fleece-lined latex gloves for work in cold weather.
Power Hammers and Drills
The use of contractor-grade power drills and rotary hammers would be essential for several workers. There are now both corded and battery-powered instruments available. They are necessary for many finishing activities, such as installing posts and railings to stream steps or adding sill plates and ledgers to foundations.
Rubber boots promise that you can walk on the asphalt. They help you to work in the concrete while standing and protect you from skin irritation.

They’re waterproof. Plus, the gear is resistant to pollutants, concrete employees have to select footwear that is often convenient to wear. Concrete staff often spend hours in their boots every day, so the selection must be as comprehensive as for premium leather work boots. Pros say that for protection and drawstring tops, rubber boots should have steel toes that secure the boot around the ankles to prevent concrete from penetrating.
Rain, drainage, or snow can lead to water-filled forms of concrete.
Before a pour, bailing out water by hand can use up precious time. With a relatively small staff, a motorized water pump will get rid of the water quickly.
To transport small quantities of concrete or to hold equipment across the site, wheelbarrows are necessary. They are also useful for taking samples of concrete for slump testing or other evaluations.
High-duty instruments with durable pneumatic tires that can stand up to the heavy loads and continuous duty needed on job sites should be wheelbarrows for concrete jobs. Trays made of steel or heavy poly, with 6 to 8 cubic feet, are standard.
During the pouring of asphalt is being done, vibrators are used to settle and compact concrete. The goal is to shake and eliminate air pockets from the wet concrete. They make sure the slab or foundation becomes more robust.
Four basic types of concrete vibrators exist:
They are also called needle or poker. A vibrating probe that is embedded in the wet concrete is part of this kind.
This type attaches to the outside of the concrete shape to produce vibrations that remove voids along the shape’s edges.
The type that attaches to a screed during screening to vibrate the concrete body.
Within a mold, this type has a vibrating metal table for vibrating concrete
At the work site, a handheld mixer helps you to blend tiny volumes of concrete. Mixers come in handy with pours that are too thin to merit ready-mix order but bigger than what you would easily mix in a wheelbarrow or mixing bowl.
Do you have units that fit in the back of a pickup truck? Or can you drag them to the worksite? Compact mixers come in various sizes. There are also electric and gas-powered versions.
A sizeable motorized tool is a plate compactor. It is used for granular surface compacting. The tool works on various fields, such as a sub-base of gravel or sand.
For a concrete slab to rest on, the construction instrument helps create a dense, tightly packed surface. On uneven or unstable soils, they are most useful. Use them where achieving a stable basis on which to pour the concrete is essential.
Shovels for small concrete repair jobs
To pass small volumes of concrete around a pour to cover voids or depressions to get to hard-to-reach places, shovels are necessary.
On-hand shovels are often needed to clear excess concrete from overfilled shapes. Square-ended shovels are used by most concrete builders rather than squared, garden-type versions.
On a concrete worksite, several power saws are standard.
- In the removal and demolition of old concrete, concrete saws are used. They are sometimes used to cut control joints until the concrete is hardened.
- Standard woodworking saws must cut parts for wood shapes.
- Do you want to cut rebar or other materials? If so, reciprocating saws or chop saws with metal-cutting blades are used.
For pouring in parched or wet weather, a bucket or pail for water is useful. The concrete is made more manageable by a limited volume of water applied during the finishing process.
Curing Compound and Hand Sprayer
The curing compound is specifically applied to a wet concrete surface to minimize cracks and help settle the concrete at the optimal point.
The mixture is usually sprayed onto the concrete with a hand sprayer for residential and small commercial projects.
The standard (and preferred) method for leveling forms and fixing their elevation is a laser level now. They are also useful for the height of embedded components, such as bolts and other anchors, to build or search.
To have a straight level or plumb line, laser levels give a beam of light.
Groove Cutters and Edgers
Groove cutters, commonly known as groves, are used on sidewalks, walkways, driveways, and residential slabs to produce control joints. A concrete saw is usually not used. To cut the groove, several grooves provide a horizontal plate with a vertical fin. To form the edges of the groove, the track late also has rounded ends.
An edger with a rounded edge that helps mold a slightly rounded-over border around the sides of a slab or sidewalk is a related instrument.
A critical aspect of concrete function is floating. It involves tooling the wet concrete’s surface with a combination of flat metal or wooden surfaces to produce a smooth finish by raising liquid cement to the surface. The bulk of metal floats are made of magnesium today.
A bull float is a wide float used to smooth and level the top of the concrete directly after it is screeded. Usually, it requires a long pole to extend around the shape.
To avoid moisture from evaporating from concrete structures, which weakens the concrete, vapor barriers or retarders are used. To prevent seawater from mixing with the concrete or prevent dry-based materials from drawing water from the concrete, walls may often be mounted underneath the concrete until it is poured.
As a concrete vapor shield, Regular 6 mild plastic sheeting does not perform very well. The thin plastic would not resist the passage of moisture under slabs. Still, when laid over asphalt, it works well enough as it dries to help cure it. The best substrate for a proper vapor barrier under the concrete is sheet plastic that complies with the specifications of ASTM E-1745, “Standard Specification for Water Vapor Retarders Used under Concrete Slabs in Contact with Soil or Granular Fill.”
