Scour Protection for Bridges & Piers

Scour Protection for Bridges and Piers

Synthetex manufactures fabric-formed concrete armoring systems to combat underwater scour and erosion at bridge abutments and piers.

When in need of protection against scour or corrosion at a bridge, rely on Synthetex to manufacture a custom solution for you. Our HYDROTEX concrete fabric forms are pumped with fine aggregate concrete. HYDROTEX has the performance to be pumped underwater, creating a concrete mattress that conforms to the shape of the soil at the bridge’s foundation.

The result is a hard armor that combats hydraulic forces and prevents the movement of sediment and soil due to local hydraulic conditions.

When is scour protection, abutment protection, or pile jackets needed?

If you are working on a project that features a bridge, pier, or other structure that crosses water, then you must take the necessary precautions to prevent hydraulic forces from compromising the structure’s stability.

An effective way to do that is by placing HYDROTEX, a concrete armor at the base of the bridge’s piers or piles, which protects against localized vortices that could leave the pile caps exposed.

Why choose HYDROTEX® for your bridge and pier scour protection project?

Bridges and piers are subject to underwater scour, leaving the surrounding environment vulnerable to catastrophic structural failure.

HYDROTEX fabric-formed concrete mattresses are designed to be installed both on land and underwater, making them the top solution for engineers, consulting firms, and DOT directors looking to protect bridges from scour before it compromises the bridge’s stability.

The most popular solutions for bridges and piers are scour protection and remediation, abutment protection, and pile jackets and seals.

Our team of highly trained and skilled engineers will carry out all necessary calculations and walk you through our recommended solutions for your specific bridge or pier project. Give us a call at 1-800-253-0561 to connect with one of our engineers today.

How is HYDROTEX used in bridge abutment protection projects?

Bridge abutment before HYDROTEX installation

The Problem

Water velocity, wind, and/or wave run-up cause soil loss and bed degradation at bridge abutments.

When soil is lost underneath the abutment, the structure will settle downward, causing a difference in elevation and forming cracks that will lead to irreparable damage and structural failure.

Bridge abutment after HYDROTEX installation

The Solution: HYDROTEX Fabric Forms for the In-Situ Casting of Concrete

Prevent failure by using HYDROTEX fabric forms for the in-situ casting of concrete. With a custom-made HYDROTEX fabric form, you can cast a permanent mattress or grout bag that conforms to the scour depth and stabilizes the abutment.

One principal benefit of our product is that it can be installed under water. It’s also much easier to install in low head clearance conditions. Rip rap, for example, isn’t as easy to install in such conditions.

Best HYDROTEX Products for SCOUR PREVENTION AT BRIDGE ABUTMENTS

Articulating Block Concrete Mat on Slope

HYDROTEX® Articulating Block Fabric Forms (Fabriform)


Cast an articulating block concrete mattress to protect an abutment with HYDROTEX Articulating Block fabric forms. We manufacture the fabric forms with internal revetment cables that aid articulation and permit flexibility. Once cast in place with fine aggregate concrete, you’ll get a custom mattress that remediates and prevents scour. This is the most popular product for bridge abutment protection projects.


HYDROTEX® Grout Bags for Bridge Abutment Protection


Easily cast a grout bag with a custom-made HYDROTEX grout bag fabric form. Another popular choice for bridge abutment protection projects, a grout bag will fill the scour hole and prop the abutment back up if the local scour has already effected a difference in elevation. Grout bags are made with 100% custom width and height for any type of bridge abutment.

How is HYDROTEX used in bridge pier protection projects?

The Problem

Local scour at bridge piles (piers) can leave the foundation exposed, causing irreparable structural damage to the bridge. Such damage may necessitate tearing down the whole bridge and re-building it, costing millions of dollars to departments of transportation and municipal authorities.

The Solution: HYDROTEX Fabric Forms for the In-Situ Casting of Concrete

Prevent and remediate scour by casting a permanent mattress or grout bag with HYDROTEX fabric forms for the in-situ casting of concrete. These mattresses and bags will conform to the scour depth and stabilize the bridge pile.

Unlike pre-cast products, HYDROTEX can be installed underwater with more ease and is suited for installation sites with low head clearance conditions. Additionally, the HYDROTEX mattress is customized to accommodate the shape and size of the bridge pile, ensuring optimal scour prevention performance.

HYDROTEX® Grout Bags

Grout (Concrete) Bags


Synthetex’s HYDROTEX® Grout (concrete) Bags (GB) and tubes are an economical and convenient choice for applications requiring concrete, grout or sand filling.  Constructed of the high-strength polyester fabrics and using a heavy-duty sewing process, our bags are ready to perform in your most demanding construction or repair installations.  The custom designed bag is available in a variety of materials and a wide assortment of dimensions, porosities, volume capacity, and filling valve types that ensure compatibility with your applications.  Their flexibility and size makes them ideal for installation through confined spaces.

Synthetex provided more than 70 grout bags ranging from a 1.5 m³ to 168 m³ capacity for the repair of an airstrip jetty in the Shetland Islands, Scotland.  The bags were first filled with water and then the water displaced with concrete to permanently fill voids in the rock jetty.

The bags provide the formwork required to cast concrete elements with the mass and stability to withstand the waves and rapidly flowing water.  The concrete grout bags may be placed side-by-side or stacked to form an inherently interlocked concrete structure.  As with our HYDROCAST® formworks, concrete grout bags can be positioned and filled with concrete from the surface in shallow water or by divers in deeper water.

Since they are cast-in-place, they intimately adapt to variations in the subgrade or bottom contours. Installations do not require dewatering, a crucial advantage in emergency repair of scour aprons.  Unlike rock or precast concrete blocks, they do not require placement by heavy lift cranes working from the land or from barges.

Synthetex’s grout bags can be used to help with the following:

  • Breakwater, dike, groin and jetty repair
  • Bridge column repair
  • Culvert aprons
  • Embankment stabilization
  • Grout bag underpinning
  • Seawall and quay wall repairs
  • Scour repairs
  • Vertical drains
  • Void filling

Pile Guards

Pile Guards (PG)


The effect of the marine environment on structural materials can be harsh and unforgiving.  The service life and structural capacity of elements composed of reinforced concrete, structural steel, timber, and composites are affected by spaling, rust and hostel marine environments.

Repairs to underwater bridge elements have been successfully completed for many years. However, the increased age of the bridges and related structures around the world, as well as the increased emphasis in regular underwater inspection by national bridge standards indicate an increased need to perform repairs to elements located below or in water.

Synthetex’s high-strength HYDROTEX Pile Guards Fabric Formed Concrete pile jacket repair systems are available in lengths and diameters designed to armor your steel, concrete or timber piles with custom solutions and not restricted to the standard diameters.  Fabric formed pile jackets are a proven economical solution for the pile repair and protection.

HYDROTEX® Articulating Block

Articulating Block (AB) Concrete Linings

Articulating Block (AB) Concrete Linings


Articulating Block Mats form cable-reinforced concrete block mattresses that resist erosive forces. They are often constructed where a revetment is exposed to frontal attack by wave action.

AB Mats are typically used to protect coastlines, canals, rivers, lakes, reservoirs, underwater pipelines, bridge piers, and other marine structures from propeller wash, ship wakes, wind waves, currents, and high velocity flows. They are also used in environmental construction for landfill caps, down chutes, and collector channels.

The AB fabric form consists of a series of compartments linked by an interwoven perimeter. Grout ducts interconnect the compartments, and high-strength revetment cables are installed between and through the compartments and grout ducts.

Once filled, the AB Mats become a mattress of pillow-shaped, rectangular concrete blocks. The interwoven perimeters between the blocks serve as hinges to permit articulation. The cables remain embedded in the concrete blocks to link the blocks together and facilitate articulation.
