Engineered retaining walls that hold back soil, control erosion, and create usable outdoor space — built to last in Inland Empire conditions.
Newline Concrete & Pavers designs and installs retaining walls throughout Colton and the surrounding Inland Empire. From small garden walls to multi-tier structural walls on sloped lots, every project is built with the right materials, proper drainage, and the foundation work that determines whether a wall lasts decades or fails in a few years.

Retaining walls fail for predictable reasons: inadequate footings, no drainage behind the wall, wrong material for the load, or improper reinforcement. We’ve seen plenty of homeowners pay twice — once for a wall that looked fine on day one and failed three years later, then again to do it right.
The pressure behind a retaining wall is significant. A wall holding back four feet of soil can have thousands of pounds of lateral force on it, especially after a heavy rain when saturated soil weighs more and drainage matters most. That’s why every Newline retaining wall starts with the engineering, not the aesthetics.
What our customers get with every retaining wall:
Retaining wall cost depends heavily on the specifics of your project. The biggest factors:
Because the variables are wide, we don’t quote prices over the phone. We come out, walk your property, measure the slope and length, ask about how you want to use the space, and provide a written estimate with scope, materials, timeline, and price.

We walk your property, measure the area, evaluate soil and drainage conditions, and discuss what you want the wall to do — hold back soil, create a planter, level out a yard, or all of the above.

We recommend the right wall type and material based on the height, load, drainage, and aesthetic you want. For walls requiring engineering or permits, we coordinate that work upfront.

The trench is dug to proper depth and width. For most structural walls, this means below frost line and onto undisturbed soil. The footing is formed and poured.

Whether poured concrete, block, or stone, the wall is built course by course (or pour by pour) with reinforcement and drainage integrated as the wall goes up.

Gravel backfill is placed behind the wall with drain pipe at the base. Final grading directs surface water away from the wall.

We walk the completed wall with you, point out the drainage features, and explain how to keep the wall performing for decades.
Newline Concrete & Pavers builds retaining walls throughout Colton and the surrounding Inland Empire, including San Bernardino, Rialto, Fontana, Redlands, Loma Linda, Grand Terrace, Highland, Riverside, Moreno Valley, Jurupa Valley, Bloomington, and Yucaipa.
In most jurisdictions, retaining walls under 4 feet (measured from the bottom of the footing to the top of the wall) and not supporting a surcharge load do not require a permit. Walls above 4 feet, walls supporting structures or driveways, and walls in certain zones do require permits and often engineering. We’ll let you know what your project needs during the estimate.
A properly designed and built retaining wall — with adequate footings, reinforcement, and drainage — should last 50+ years. Most retaining wall failures happen because of inadequate drainage or insufficient footings, not because of the wall material itself.
Poured concrete walls offer the highest structural strength and a smooth, monolithic look. Concrete block walls (CMU filled with concrete and rebar) offer comparable strength with more aesthetic flexibility and are often more cost-effective for residential heights. The right choice depends on your project’s height, load, and design.
Soil weighs significantly more when it’s saturated with water. Without proper drainage, water pressure builds behind the wall (called “hydrostatic pressure”) and can push even well-built walls over time. Every wall we build includes gravel backfill, drain pipe, or weep holes — whatever the wall and site need.
Sometimes. Minor issues caught early can be repaired. Walls with significant lean, bulging, or structural cracking usually need replacement — patching a failing wall is rarely cost-effective and the underlying cause (almost always drainage) needs to be fixed regardless.
Practically, we build walls from 1 foot up to walls requiring engineering and permits. The height limit is set by what the soil, footing, reinforcement, and (above a certain point) engineering can support — not by what’s possible to construct.
If your yard has erosion, a slope you can’t use, soil pushing against an old wall, or grading problems that come back every winter — a proper retaining wall solves it. Newline Concrete & Pavers builds walls that last.
