Welcome to our erosion control project portfolio.

An inspection revealed a leak in the stormwater control (SCM) system. Upon excavation, water was leaking from the pond beneath the riser and from both 3-foot diameter reinforced concrete pipes (RCPs) at the outlets. The leak was traced to an unsealed joint about 5 feet from the riser, underneath the top of the dam.

To address it, geotechnical sealing was applied around the riser and between the outlet RCPs, and the joints were sealed with hydraulic cement. Finally the area was stabilized and the project was completed.

Slope stabilization is a range of techniques used to prevent landslides, collapses and erosion on slopes and embankments. The goal is to keep soil in place and minimize damage to surrounding infrastructure and the environment.

In this work you can see two small retaining walls:

• A 5-foot wall, with 4 feet above ground and 1 foot of foundation.
• A 3-foot wall, with 2 feet above ground and 1 foot of foundation.

Both walls include a French drain in the foundation and a clean-out with solid pipe that connects from the perforated pipe upward, leading into a T connection.

Blocked water valves due to debris can significantly affect the urban drainage system and increase erosion. When drainage is obstructed, stormwater flow is disrupted, water accumulates, and the risk of flooding and soil erosion rises.

For effective erosion control it is essential to keep drainage systems, including water valves, clear and fully operational. At Delcid we have the skilled team and the right tools to restore flow and deliver long-lasting results.

At Delcid we have the expertise to install dissipater pads that reduce water flow velocity and prevent erosion. Our technicians excavate the area based on the stone's size and classification, so the pads are installed to engineering specifications designed to withstand the force of water flow over the long term.

We use dissipater pads in applications such as swales, ponds, plunge pools and berms, delivering durable, efficient erosion control.

This pond conversion was carried out to meet the required design elevations and ensure long-term stabilization. To achieve compliance with project specs and long-term performance, the following measures were used:

• Double net matting for slope stabilization.
• Core matting at the bottom of the pond for additional reinforcement.
• Permanent seeding to establish sustainable vegetation.

Together these manage stormwater, control erosion, support environmental resilience and maintain the structural integrity of the site.

Two berms were built at the end of both streets, with lining and stone reinforcement to control runoff and prevent erosion beyond the Limits of Disturbance (LOD). Sod was installed throughout the surrounding common areas to stabilize the site and promote long-term vegetation.

A silt fence system protected the vegetated areas and stone installations, particularly due to adjacent undeveloped lots, and rubber wattles were added as a first line of defense to intercept sediment before reaching the stone. The system ensures controlled drainage, site stability and long-term erosion protection.
