Concrete Installation and Repair
Plan concrete work around the area’s intended use, existing condition, proposed finish and access requirements.
Concrete walls and the ground around them.
Concrete for the way the space is used
A walkway, equipment pad and set of steps each ask something different of concrete. The shape, base and finish need to work together with the intended use and the surrounding ground.
Beyond the visible surface
Preparation and support beneath a slab influence its performance. Cracking, sinking or recurring water at an existing area can point to issues that a surface patch alone will not resolve.
Finish and connections
Texture affects the look and feel underfoot, while edges and transitions determine how the new work meets paths, doors or landscaping. Those details help make a small pad or a larger replacement feel part of the property.
Repair or replacement?
An isolated damaged area may suit a different solution from widespread movement. The quote can separate removal, base work and finishing, with reopening instructions based on the actual concrete work and conditions.

Concrete & interlock
"D&D replaced a badly spalled garage apron on one of our managed properties. They broke out the old work, prepped the base properly, and the finished surface is flawless."

Read this testimonialPlan the work and handoff
Resolve preparation before placement
Agree the area, supporting work, finish and joint plan before new concrete is placed.
Protect and reopen
Obtain curing and use instructions for the actual work and conditions; a finished-looking surface is not a reopening timetable.
Before the assessment
Record the condition
Photograph cracking, settlement and places where water collects, including how the area meets doors or steps.
Explain access
Describe equipment access and where removed material and deliveries can be handled.
Plan alternate routes
Identify vehicle and pedestrian access that must remain available while the work is protected.

Questions about Concrete Installation and Repair
Is a crack always a reason to replace the concrete?
Not necessarily. The extent of damage, movement, use and surrounding condition need assessment. Compare a local repair with replacement of the affected area rather than assuming the visible width of a crack gives the whole answer.
Why does a quotation include joints?
Joints are part of planning movement and cracking in concrete flatwork. Ask how the proposed joint layout relates to the shape and adjoining structures; it should not be treated simply as a decorative line pattern. NRMCA: joints in concrete slabs
Can a new slab be put over damaged concrete?
Have the existing condition and intended use assessed first. A new surface does not automatically correct settlement, inadequate support or awkward levels, and the quotation should explain what preparation or removal is proposed.
How is the surface finish chosen?
Discuss appearance, use underfoot and the transitions to existing paths or entrances. Review the proposed finish with its care requirements and the practical use of the area rather than selecting solely from a photograph.
When can I park on new concrete?
Obtain the reopening instructions for the concrete placed, site conditions and intended vehicle use. Do not infer readiness from appearance or a generic number of days; arrange alternative parking until the agreed guidance permits use.
What belongs in the removal allowance?
Identify the area and material being removed, disposal, access and any reinstatement beyond the slab edge. A replacement quotation should also explain how unexpected underlying conditions would be assessed and approved.

Concrete & Cement Work in Kitchener-Waterloo
D&D Exterior Finishing installs concrete driveways, walkways, steps, and patios throughout Waterloo Region. In Ontario's demanding climate, concrete that isn't properly mixed, reinforced, and finished will crack and heave within a few seasons. We do it right the first time.
Why Concrete Requires Expert Execution in Ontario
Southern Ontario experiences more freeze-thaw cycles per year than almost anywhere else in Canada. Each freeze-thaw cycle puts enormous stress on concrete — forcing water into micro-cracks, expanding it as it freezes, and widening those cracks further with every season. Properly air-entrained concrete, adequate thickness, steel reinforcement, proper sub-base preparation, and appropriate control joints are what separate concrete that lasts decades from concrete that fails in three years. D&D Exterior Finishing uses commercial-grade practices on every residential project.
Types of Concrete Work We Do
01
Concrete Driveways
A properly installed concrete driveway lasts 30–50 years with minimal maintenance. We excavate to proper depth, install a compacted granular sub-base, reinforce with rebar or wire mesh, and pour air-entrained concrete at the correct thickness — including proper control joint placement to manage natural cracking.
02
Walkways
Concrete walkways add curb appeal and safe footing year-round. We pour walkways with a broom finish for slip resistance, proper slope for drainage, and expansion joints to accommodate seasonal movement. Exposed aggregate and stamped finishes are available for decorative applications.
03
Concrete Steps
Concrete steps require proper reinforcement and a solid footing below the frost line to prevent heaving and separation from the house. We form and pour steps to exact riser-and-tread dimensions that meet Ontario Building Code safety requirements — broom-finished for year-round traction.
04
Concrete Patios
A concrete patio is a durable, low-maintenance outdoor living surface that won't shift or weed like interlock. We offer standard broom finish, exposed aggregate, and stamped concrete patio options — all poured over a proper compacted sub-base with drainage slope away from the foundation.
Our Concrete Installation Process
- Excavation & Sub-Base Preparation — We excavate to proper depth, remove all organic material, and install a minimum 4-inch compacted granular sub-base. Good drainage starts below the slab — never on top of it.
- Forming & Reinforcement — Forms are set to the correct grade and slope. Rebar or wire mesh reinforcement is installed to reduce cracking and hold the slab together if cracking does occur.
- Concrete Pour & Finishing — Air-entrained concrete is poured, screeded, and finished to the specified texture. Control joints are cut or tooled at proper intervals to direct natural cracking to predictable locations.
- Curing & Sealing — Concrete is cured properly to achieve full strength. A penetrating concrete sealer is applied to protect against moisture infiltration, de-icing salts, and freeze-thaw damage — significantly extending the slab's lifespan.
Why Waterloo Region Homeowners Trust Us
- Air-Entrained Concrete SpecifiedWe specify air-entrained concrete mixes for all exterior work — the industry standard for Ontario's freeze-thaw climate. This is the single biggest factor in concrete longevity.
- Proper Sub-Base Every TimeWe never pour over unstable or poorly compacted base material. Proper excavation and granular sub-base is non-negotiable on every project.
- Control Joints IncludedWe cut or tool control joints at correct spacing to manage where cracking occurs — preventing random, unattractive crack patterns.
- Sealer Applied as StandardEvery concrete project we complete receives a penetrating sealer application to protect against de-icing salt damage and moisture infiltration.

Frequently Asked Questions About Concrete Work
How much does a concrete driveway cost in Kitchener-Waterloo?
Concrete driveway costs depend on size, thickness, finish type, and site conditions. D&D Exterior Finishing provides free, itemized written estimates. Contact us for a quote specific to your property.
Is D&D Exterior Finishing licensed and insured for concrete work?
Yes. We are fully licensed and insured for all concrete work in Ontario, WSIB compliant, and experienced in residential and light commercial applications.
Do you offer a warranty on concrete work?
Yes. All concrete projects include our workmanship warranty. We'll clearly state coverage terms in your written estimate before work begins.
When is the best time to pour concrete in Ontario?
The best window for concrete work in Waterloo Region is May through October when temperatures are consistently above 10°C. Concrete can be poured in cooler temperatures with proper precautions, but we typically avoid pouring when nighttime temperatures will fall below 5°C in the 7 days following the pour.
Do you serve my area for concrete work?
We pour concrete throughout Kitchener, Waterloo, Cambridge, Guelph, Elmira, Ayr, New Hamburg, Baden, Woodstock, Brantford, Breslau, and surrounding communities.
Why does my existing concrete crack and how do you prevent it?
Concrete cracks for three main reasons: inadequate sub-base that allows settlement, insufficient control joint spacing, and non-air-entrained concrete that can't handle Ontario's freeze-thaw cycles. All three are addressed in our standard installation process — resulting in concrete that lasts 30–50 years rather than 5–10.
Can concrete be stamped or coloured for decorative applications?
Yes. We offer exposed aggregate, stamped, and integrally coloured concrete finishes for patios, walkways, and driveways. Stamped concrete can replicate the look of stone or brick at a lower cost than natural materials, with the durability of a solid concrete slab underneath.
