Poured concrete retaining walls in Fredericton are cast in place inside forms with steel reinforcing, creating a thin, strong wall that suits tight side yards, driveways, loading areas and modern landscapes. This page explains when poured concrete beats block or stone, how footings and drainage are handled, what affects the cost, and how to book a free estimate.
When is a poured concrete retaining wall the better option?
A poured concrete retaining wall is the better option when there is little room behind the wall, when it has to carry a heavy load such as a driveway or building, or when you want a smooth, modern face. A cast wall with a reinforced footing can hold a tall grade change in a fraction of the depth that armour stone needs.
That makes poured concrete common beside walkout basements, garage approaches, commercial parking areas and narrow lots in older Fredericton neighbourhoods. The face can be left smooth, board-formed for texture, or finished with stone veneer later.
How is a poured retaining wall built to resist frost?
A poured retaining wall resists frost through a footing placed below the frost line, steel reinforcing sized for the soil load, air-entrained concrete, and drainage behind the wall that keeps water from freezing against it. Fredericton winters drive frost deep, so the footing depth is set for local conditions rather than copied from a warmer climate.
Behind the wall we install a drainage membrane or clean stone with a perforated pipe, plus weep holes where the design calls for them. Control joints guide shrinkage cracks to straight, planned lines. Each of these steps is inexpensive during the build and very hard to add once the wall is backfilled.
How much does a poured concrete retaining wall cost in Fredericton?
The cost of a poured concrete retaining wall in Fredericton depends on the wall's height and length, footing size, the amount of reinforcing steel, the formwork finish, and access for the concrete truck or pump. Taller walls need thicker sections and more steel, and engineered walls follow the designer's specifications.
Excavation in clay, dewatering a wet site, removing an old wall, and decorative finishes such as board-formed texture or veneer also affect the total. We provide a free, itemized written estimate that shows each part, including any engineering or permit steps.
Does a tall poured concrete wall need an engineer?
A tall poured concrete wall usually needs an engineer, especially when it supports a driveway, a structure or a steep slope, because the footing size and reinforcing must be calculated for the actual loads. We check the City of Fredericton's requirements for your wall before construction and work from stamped drawings where they are required.
Engineering protects you as well as the wall. It documents that the design suits the soil, which matters when you sell the property or when the wall sits near a property line or public sidewalk.
When a wall is engineered, the drawings set the footing width, steel size and spacing, concrete strength and drainage details. We build to them exactly and keep a record of inspections, so you have proof of what is inside the wall long after the forms are gone.
Can poured concrete be finished to look like stone?
Poured concrete can be finished to look like stone by using textured form liners, applying a manufactured or natural stone veneer after curing, or adding a stone cap. Veneer lets you combine the strength and slim profile of concrete with the look of natural stone near the house.
If stone is the main goal, compare our natural stone retaining walls page. For walls that hold up a driveway, see driveway retaining walls, where poured concrete is often the strongest solution.
Common questions about Poured Concrete Retaining Walls in Fredericton
Will a poured concrete wall crack?
All concrete shrinks slightly as it cures. Control joints, proper reinforcing and drainage keep cracks small, straight and cosmetic rather than structural.
How long before the wall can be backfilled?
The concrete needs time to gain strength before soil is placed against it. We schedule backfill based on the mix, the weather and the wall design.
Can a poured wall be built in the fall?
Yes, until the ground freezes. Cold-weather precautions such as blankets and heated concrete are used when temperatures drop.
