Keeping shorelines safe from erosion and deterioration is no easy feat. Many contributing factors like waves and currents, storms and rising sea levels overtake beaches and remove sand, changing the coastline. These are natural environmental occurrences but can become damaging for marinas and beaches when landslides take place and dunes are formed.

Shoreline maintenance projects like retaining walls, groynes and wave attenuation can help diminish the impact of beach erosion by regulating water current energy to reduce the effects. Groynes act as barriers built into the water from the shoreline to protect beach drift. Retaining walls are commonly used where elevation occurs to stabilize sand and dirt and wave attenuation includes low walls or fences located underwater to dampen wave and current energy from coming to shore.

Erosion can cost a lot of time and money to fix, and finding the right building material for shoreline maintenance applications can be difficult because these projects have many performance characteristics that must be met to achieve success. The material must remain intact when submerged in water and not have a negative impact on marine life. Traditionally, these projects are constructed using wooden timbers, concrete and metal. However, conventional building materials can fall short and require long-term maintenance and cost because the performance characteristics don’t meet all the requirements.  

Bedford Technology Products

Bedford Technology offers four product lines that offer long-term durability and varying degrees of strength to provide a diverse range of shoreline maintenance building materials. HDPE plastic lumber provides an environmentally-friendly solution that will keep your coastline controlled.

FiberForce® by Bedford Technologycontains fiberglass strand for enhanced rigidity. The added rigidity increases strength and durability, ensuring high performance and long-term results. Use FiberForce® for retaining walls and wave fences.

BarForce® by Bedford Technologyreinforced with fiberglass polymer rebar, this commercial-grade HDPE plastic lumber building material offers resilience and compressive strength properties. BarForce® allows for longer spans and is best-suited for marine projects like retaining walls, groynes and erosion control.

SeaPile® and SeaTimber® by Bedford Technologyare premium solid composite piles and timbers fortified with fiberglass polymer rebar. These product lines are engineered using the multiple extrusion manufacturing process which allows the material to withstand heavy impacts by absorbing energy through recoverable deflection. Use these product lines for heavy-duty marine applications like wave attenuation, groynes and retaining walls.


Bedford Technology’s structural recycled plastic lumber offers performance characteristics perfect for heavy-duty marine applications that require increased strength properties. Able to withstand extreme weather conditions like ice, extreme heat, cold and high levels of moisture, structural HDPE plastic lumber won’t mold, rot or degrade and is resistant to marine borers and crustaceans.

Bedford Technology products are sourced from post-consumer and post-industrial recyclables like milk jugs and laundry detergent bottles. So far, Bedford Technology has helped keep millions of pounds of plastic out of landfills by repurposing it into a durable and tough building material.
