Seawalls, Bulkheads and Erosion Control

	York Harbor Marine Services, York, ME We replaced approximately 125 feet of aging timber bulkhead with a new steel sheet pile bulkhead. Bulkhead is tied back to a cast-in-place concrete pile cap inboard of the bulkhead which is supported on timber bearing piles. We then poured an 18 inch thick reinforced concrete pad behind the new sheets. Project also included a new structural steel pier capped with a precast concrete deck.

	Bayley Bulkhead, Scarborough, ME We are currently replacing approximately 200 feet of failed timber bulkhead with a new fiberglass sheetpile bulkhead. Bulkhead is constructed with GeoGuard 30 fiberglass sheet and tied back utilizing helical anchors.
	Chicks Marina, Kennebunkport, ME We replaced approximately 440' of failed timber bulkhead at Chicks Marina in Kennebunkport. New bulkhead is constructed "Navy" style with 12" soldier piles and a double 8" x 8" wale system. New sheet is Shoreguard 650 vinyl. Bulkhead is tied back with 1.25" galvanized tiebacks to a combination of buried concrete deadmen and helical anchors.
	Worthing Bulkhead, Saco, ME We replaced a failed concrete/timber bulkhead with a new vinyl sheet pile bulkhead. Bulkhead is approximately 135' long with an average exposed height of 9'. Bulkhead is constructed with Shoreguard 650 vinyl and tied back utilizing helical anchors.
	Ceres Street Bulkhead, Portsmouth, NH We completed emergency repairs to a failing granite quaywall for the City of Portsmouth. Project included installation of helical anchor tiebacks anchoring a cast-in-place concrete grade beam behind the wall, connected to new steel H-Piles, timber wales and timber fender piling.
	Chapin Bulkhead, Scarborough, ME We completed a bulkhead replacement/dune restoration for this property in Scarborough. Pernitting and design was by Baker Design Consultants of Yarmouth. In order to match the bulkheads in the area, the new bulkhead was constructed with three layers of timber. Beacuse of the location of the house on the property, it was necessary to bring all materials in via the beach. In order to speed construction, the wall panels were prefabricated in our shop and trucked to the site. We also imported almost 300 CY of sand for the dune restoration. Bibb Rock Landscaping of Cape Neddick planted almost 9000 new dunegrass plants to complete the restoration.
	Lawrence Seawall, Hampton, NH We completed the design and permitting for this stone seawall along with the construction. The existing seawall had been constructed of poorly graded stone with the remnants of the original concrete seawall mixed in. We removed the existing stone and concrete, installed a geotextile filter fabric, rip rap and a facing of 1 to 2 ton armor stones.
	Kay Quaywall, Biddeford Pool We reconstructed approximately 90 lineal feet of an existing 12' tall granite quaywall. We removed stones down to the mudline and reconstructed the wall, installing a geotextile filter fabric as we went and pinning each stone into the two stones below it. At approximately 8' up the wall, we installed steel tieback rods back to the existing ledge approximately 30 feet behind the wall. Once the quaywall was reconstructed, we reconstructed a pier in front of it, complete with floating docks and a gangway.
	Dolloff Revetment, Saco, Maine We replaced approximately 150 LF of failed timber bulkhead with a stone revetment consisting of a layer of non-woven filter fabric, a 2' layer of 4"-8" Rip Rap protected by a layer of 1 to 2 ton Armor Stone. We also constructed a small walkway/pier for access to the existing float.
	Card Revetment, Cape Porpoise We constructed approximately 50' of shoreline protection at this property in Cape porpoise which had begun to suffer from extreme erosion due to storm action and boat wakes. We dug a series of large (2' x 2' x 4') stones a minimum of 12" into existing grade to form a toe, installed a heavy duty geotextile against the existing slope and placed 6"-12" riprap stone behind the toe. Because of property issues and a desire to minimize damage to the existing landscape, all 75 tons of stone were brough to the project site by barge.
	Phillips Revetment, Kennebunk We completed substantial repairs to an existing gabion revetment at the mouth of the Mousam River in Kennebunk. Repairs were conducted utilizing Maccaferri gabion baskets filled with 4" rip rap stone. Once the new baskets were wired in place and filled, we anchored them utilizing Manta Ray anchors driven 10' into the existing bank.
	Smith Seawall, Biddeford We completed repairs to a severely undermined concrete seawall on Hills Beach in Biddeford. We excavated below the existing seawall to form and pour a new foundation. Once the forms were stripped, we installed a tongue and groove timber bulkhead facing.
