Treated Wood Pilings for Texas Projects
Wood piling requirements vary according to the project location, structural application, water exposure, treatment level, dimensions, and project specifications.
Projects around Houston and Corpus Christi may require pilings for marine, shoreline, foundation, dock, pier, or coastal construction. Dallas and North Texas projects may include freshwater, foundation, commercial, structural, and lakefront applications.
Our Houston location maintains inventory and wood treating capabilities, and pilings can be prepared according to project requirements before delivery.

Wood Piling Options
Treated Round Pilings
Round pilings are strong, long-lasting, and cost-effective wood members used in marine, shoreline, foundation, and specialty construction.
Because round pilings have minimal exposed heartwood, pressure treatment can protect more of the wood along the length of the piling.

Square Timber Pilings
Square timber pilings provide straight sides and consistent dimensions. They are used for foundations, bulkheads, fences, fender systems, and other projects requiring substantial square timbers.
Available sizes range from treated 6 × 6 timbers to 12 × 12 pilings and larger.
Available sizes range from treated 6 × 6 timbers to 12 × 12 pilings and larger.
Gun Barrel Pilings®
Gun Barrel Pilings® are solid wood pilings machined to create a uniform diameter without the natural taper found in regular round pilings.
They combine the natural appearance of a round wood piling with the visual and dimensional uniformity associated with square timber pilings.

Poly Coated Wood Pilings
Poly coated pilings combine pressure-treated wood with a protective polymer coating. The piling is treated to the required retention level, kiln dried, and then coated.
The coating provides additional protection from insects, mollusks, and other wood-boring organisms.

What Treatment Levels Are Available?
Most wood pilings are treated with CCA. Other treatment options are available upon request. The most commonly treatment levels are:
| Treatment level | Application |
|---|---|
| 0.40 pcf | Ground-contact applications |
| 0.60 pcf | Freshwater applications |
| 2.5 pcf | Saltwater applications |
Other retention levels are available when required by project specifications, engineers, or government contracts.
Where Can Round Wood Pilings Be Used?
Foundation Pilings
Round wood pilings can be used as structural foundation members.
Beach-House Pilings
Treated round pilings can support elevated coastal and beach-home structures.
Dock Pilings
Marine-treated round pilings can be supplied for dock construction.
Pier Pilings
Round pilings are commonly used as structural members for piers.
Bulkhead Pilings
Treated wood pilings can support wood, vinyl, and other bulkhead systems.
Pile Moorings
Round wood pilings can be used for pile-mooring applications.
Dolphins
Round pilings can be grouped or incorporated into dolphin structures.
Ropes Courses
Treated round pilings can be used as structural members for ropes courses.
Pole Barns and Fences
Round pilings can also be used as poles for pole barns, fences, utility-pole applications, and other structures.
What Square Timber Pilings Are Available?
Square timber pilings range from 6 × 6 timbers for bulkheads and fences to 12 × 12 pilings and larger for foundations and fender systems.
Available options include:
- Treatment according to project requirements
- Custom cutting
- Custom drilling
- Conditioning
- Polymer coating
- Rough-cut finish
- Planed smooth finish upon request
- Marine and specialty hardware
Square timber pilings are supplied with a rough-cut finish as the standard option. Planing is available when a smoother finish is required.
What Are Gun Barrel Pilings®?
Gun Barrel Pilings® are solid wood pilings with a uniform diameter and no taper. Previously known as Solid Uniform Diameter pilings, they can replace poles, pilings, or columns in interior and exterior applications.
Available options include:
Available options include:
- Pine
- Cedar
- Douglas Fir
- Other wood species upon request
- Lengths up to 46 feet
- Diameters up to 24 inches
- Treated or untreated
- Kiln dried
- Paintable and stainable
- Interior or exterior use
Because they have no taper, Gun Barrel Pilings® are easier to build onto when used as beach-house pilings or foundation columns.
What Are Poly Coated Wood Pilings?
Poly coated wood pilings are treated to the required retention level, kiln dried, and covered with a protective polyurea coating that bonds to the wood.
The coating provides additional protection from:
- Insects
- Mollusks
- Wood-boring organisms
- Moisture exposure in marine environments
Full and zone-coating options are available. A piling can be completely coated or coated around the section most exposed to moisture and marine organisms.
Poly coated pilings can still be cut and drilled. A poly patch kit can cover areas exposed during cutting or drilling.
How Do Round and Square Pilings Compare?
| Feature | Round pilings | Square pilings |
|---|---|---|
| Shape | Natural round profile | Four flat, square sides |
| Dimensional consistency | Naturally tapered | Consistent square dimensions |
| Alignment during installation | Must be installed plumb, but no face requires squaring | Must be installed plumb and correctly squared with the structure |
| Heartwood exposure | Minimal exposure except at cut ends | Sawing can expose heartwood along the piling |
| Water movement | Rounded shape allows water to flow around the piling | Square shape creates a different flow pattern |
| Standard finish | Natural round surface | Rough-cut finish |
| Smooth finish | Not specified | Planing available upon request |
| Custom cutting and drilling | Available according to requirements | Available according to requirements |
| Polymer coating | Available | Available |
Why Piling Shape Matters?
The differences between round and square pilings extend beyond their appearance and dimensions. Their shapes also affect heartwood exposure and how water flows around them during storm surges.
Heartwood Protection
Round pilings and uniform-diameter Gun Barrel Pilings® generally have minimal exposed heartwood except at their cut ends. Sawing a timber into a square shape can expose untreatable heartwood along its length, increasing its susceptibility to rot and decay.
Water Flow During Storm Surges
Round pilings and Gun Barrel Pilings® allow water to flow more evenly around their curved surfaces. Square pilings can create a low-pressure area behind the piling, which may increase the likelihood of failure during storm-surge conditions.
Why Choose Round Wood Pilings?
No Squaring Required
Round pilings must be installed plumb, but they do not need to be rotated so one particular face aligns with the structure.
Minimal Exposed Heartwood
Round pilings generally have minimal exposed heartwood except at their cut ends.
Natural Wood Appearance
Round pilings retain the natural profile and appearance of the original wood member.
Marine and Foundation Applications
Treated round pilings can be supplied for structures built on land, along shorelines, or in water.
Multiple Treatment Levels
Treatment levels are available for ground-contact, freshwater, saltwater, and specification-based applications.
