We install rip rap to protect your waterfront and lengthen the life of your shoreline. In some cases we install rip rap to any height in front of bulkheads for additional protection against hurricanes or severe wave action. Whether you want a little insurance against erosion at the mudline of your bulkhead or to make the strongest bulkhead in your neighborhood, we can install any variety or size of rip rap to strengthen your bulkhead.

A riprap will:

  • Protect your waterfront property
  • Help maintain your shoreline
  • Extend the life of your shoreline
  • Prevent water erosion
Your riprap can be made from a variety of rock types, including granite, limestone and concrete rubble from previous demolitions.

Types of Rip Rap materials:
  • Rubble riprap
  • Wire-enclosed rock (gabions)
  • Pre-formed blocks
  • Grouted rock
  • Paved Lining
By definition, riprap traditionally refers to a flexible revetment. Wire-enclosed rock, pre-formed block, grouted rock and paved lining, however are more rigid. Therefore, they are not always considered rip rap, but they are generally discussed along with flexible riprap.

The following information is referenced from the Federal Highway Administration.

Rock Riprap
Throughout the United States, rock rip rap is the most popular. In fact, the term “riprap” generally refers to rock riprap. It works well in most environments, and it can categorized by placement method into dumped riprap, hand-placed riprap, and plated riprap.

Types of rubble which have been used as riprap include:

  • Rock spoils: Often available from road cut or other excavation sites.
  • Broken concrete: Available in areas undergoing widespread urban renewal involving the demolition of buildings and other structures made from concrete.
  • Steel furnace slag: Sometimes available in the vicinity of steel smelting plants.
The following types of revetment are more rigid, and therefore sometimes not considered actual riprap, but they can be used for the same purposes.

Wire-Enclosed Rock
Wire-enclosed rock, or gabion, revetments consist of rectangular wire mesh baskets filled with rock.

Rock and Wire-Mattresses
In mattress designs, the individual wire mesh units are laid end to end and side to side to form a mattress layer on the channel bed or bank.

Block Gabions
More equidimensional, having depths that are approximately the same as their widths, and of the same order of magnitude as their lengths. They are typically rectangular or trapezoidal in shape.

Pre-Cast Concrete Block
Pre-cast concrete block revetments are a recent development. The pre-formed sections which comprise the revetment systems are butted together or joined in some fashion; as such, they form a continuous blanket or mat.

Grouted Rock
Grouted rock revetment consists of rock slope-protection having voids filled with concrete grout to form a monolithic armor.

Paved Lining
Concrete pavement revetments are cast in place on a prepared slope to provide the necessary bank protection.
