  • Highway Expansion Project in Virginia Beach, Virginia
  • Solar Farm Development in Virginia
  • Commercial Development in Northern Virginia

River Walk Pavilion

2020

West Point, Virginia

Plans for this West Point, Virginia park specified a permeable parking area. After the original bid came in over budget, we worked with the site-work contractor to value engineer a more cost-effective solution.

Geocell cellular confinement system was approved for the permeable surface. After grading, #57 stone was compacted over the soon to be parking lot. The stone was followed by GT142 Nonwoven Geotextile Fabric. Next, a total 9,200 square feet of 4” EGA 30 was installed and connected with EnviroLocks. EnviroLocks are similar to heavy duty zip ties. They connected the cellular confinement system’s panels together. The Geocells were filled with 5-6” of topsoil. Finally, the entire area was hydroseeded.

The Riverwalk Park Pavilion now has a green parking area that is stable enough to bare the load of vehicular parking.   

Commercial Turf Installation

2020

Sea Isle City, New Jersey

A Jersey Shore restaurant recently expanded their outdoor dining area. The restaurant owner wanted to create a relaxed but refined atmosphere that can could accommodate large Summer crowds. They chose Synthetic Turf for their base because the artificial grass checked all of those boxes.

After the site was cleared and graded, a local contractor added a layer of geotextile fabric. The fabric was followed by DGA (crushed concrete) and a layer of fine gravel. A local turf installer graded the site again to control drainage.

A total of 5,820 Square Feet of Shaw Grass Bermuda Green-Olive was installed and filled with sand.

Hardscape Patio

2020

Virginia Beach, VA

Most hardscape patios need a geosynthetic below the pavers. It is normally the installer’s discretion to decide whether stabilization, separation or reinforcement is the priority. Depending on the project’s needs, they select a woven geotextile, nonwoven geotextile or geogrid. In this case, all three properties were a priority because of the sandy base.

A composite geogrid was chosen because it stabilizes, separates and reinforces. This composite includes a Bi-Axial Geogrid bonded to a 6oz Nonwoven Geotextile Fabric. The nonwoven geotextile separates the sand from the top fill while the geogrid stabilizes the subgrade. Now there is a stable foundation to support a beautiful hardscape patio.

Thalia Stream Restoration

2020

Newport News, VA

Tree overgrowth and stream bank erosion threatened the livelihood of this Newport News stream. If not properly restored, the erosion would lead to flooding and increased sedimentation in the stream. A precast MSE retaining wall was installed to mitigate future erosion.

A 200-pound woven geotextile fabric was installed before the first precast concrete block was placed. The fabric wrapped behind the wall block and acts as a separator between the block and the retained backfill. The precast wall blocks were installed and voids were filled with compacted #57 stone. Once the MSE retaining wall was completed, the woven geotextile fabric wrapped over the top of the stone. Top soil and straw erosion control blanket capped the top of the structure and an HDPE pipe was installed to control drainage.

Further down the stream, coir matting was installed to control stream bank erosion close to the outlet.

Highway Expansion Project

2019

Virginia Beach, VA

Long term interstate improvement projects require long term solutions for erosion and sediment control. This VDOT project has utilized Recyclex erosion control blankets, VDOT Approved Drainage Fabric for separating sandy soils, High Visibility Orange Barrier Fence, Silt Fence and Turbidity Curtain.

Hardscape Project

2019

Tidewater, VA

A multi-level hardscape patio takes the place of what used to be a deck and concrete patio. The deck and lower patio were separated by a steep staircase. With premium hardscapes, the backyard has been transformed into a more unified space, perfect for entertaining.

Urban Perimeter Control

2019

Chesapeake, VA

Diamond Sock was installed for perimeter control at this facility expansion project. Continuous pallets were selected to cut down installation time. While the machine operator carried the Diamond Sock pallet, an installer unwound the compost filter sock and staked it into place.

Commercial Development

2018

Richmond, VA

The General Contractor wanted a well-branded site in order maximize exposure in a heavy traffic area. Colonial’s crew first installed temporary chain link and logo silt fence. Screen fence was added to chain link and custom barricades were installed to secure the site.

Renewable Energy Site

2018

It is imperative to have a quality erosion control and stormwater management plan in place when developing a site for renewable energy. Specifications often require enhanced perimeter protection, superior soil stabilization and the planting of native varieties.

On this site, our crews installed wire reinforced silt fence, orange barrier fence and Diamond Sock. Colonial also supplied erosion control blankets, geotextiles for construction entrances, hydroseeding material and custom seed mixes.

Hydroseeding New Development

2018

Virginia Beach, VA

The contractor hydroseeded the lots on this development to get the job done quickly and thoroughly. Erosion control blankets were installed around the curbs in order to prevent erosion and washouts. Colonial provided a hydroseeding mixture that included cellulose mulch, tackifier, dye and seed.

Renewable Energy Site

2018

Surry, VA

Woven Belted Silt Fence (WBSF) was installed at this renewable energy site. The heavy duty silt fence was preferred for this long-term site in order to minimize repairs and maintenance.

New Development

2017

Northern Virginia

A geosynthetic clay liner (GCL) was installed at the site of a new hospital development. Liners like this one can be used on steep slopes for protection against high internal sheer stress. GCLs are also commonly used on large bio-retention ponds.

Stream Restoration

2017

Virginia Beach, VA

This stream restoration was implemented because homeowners were experiencing a high level of erosion around their properties after major rain events. Curlex Bloc was used to provide natural support for the rehabilitation of the stream bank. Final stabilization measures included coir, a native seed mix and live branches.

Stormwater System

2016

Richmond, VA

Five sand filtration systems were installed in the development of a new shopping center. These systems have one of the highest nutrient removal ratings and offer long-term cost savings when compared to using alternative systems or BMPs.

Dulles Airport Firing Range

2016

Dulles, VA

Geocells were installed on the berm for slope stability. Once they were in place, top soil filled the void spaces in the cells. The berm was then seeded and covered with geo-jute and Coir 900.

Chincoteague Wild Life Refuge

2016

Chincoteague Island, VA

2,900 Excelsior Logs lined the roads of the Wildlife Refuge as a preventative measure for road improvements. These wood fiber logs were chosen because they provided an erosion control solution that would not compromise the preserve’s natural environment.
