Erosion and Sediment Control

Erosion and sediment control refers to the efforts to control the loss of solid material like soil and sediments. At HML Landscape and Tree Services, we ensure to choose the suiting sediment control plan for your property to prevent soil erosion. Here are a few measures we conduct for erosion and sediment control:

Erosion Control Blanket

This is a biodegradable open-weave blanket that provides temporary over and creates support on bare soil for vegetation like grass. ECBs are made of straw or coconut, which helps to stabilize the growth of the vegetation from seeding to top development. This technique helps with the prevention of soil erosion, supports seed germination and stabilizes any slopes. Its implementation is appropriate in ditches, slopes and near-water access areas. There are mainly three types of erosion control blankets:

  1. Coconut blanket (AT Type C)
  2. Straw blanket (AT Type A)
  3. Straw/Coconut blanket (AT Type B)

Fiber Wattle/Log

This method involves placing wattles or logs of various materials, sizes and lengths to trap sediments, control water runoff and prevent soil erosion. Generally, these erosion-control wattle/logs are made of natural materials like wood fibre or straw and wrapped in synthetic netting. Fibre wattles/logs are temporary control structures utilized in areas like ditches, channels and side slopes. The three primary types of erosion prevention wattles/logs are:

  1. Aspen wattle/log (wood fibre)
  2. Straw wattle
  3. Terra tubes (either artificial fibres or     wood fibres)

Synthetic Permeable Ditch Barrier

This product is designed for erosion and sediment control by decreasing the water runoff velocity in ditches and channels and dropping sediments in suspensions or deposits. Synthetic permeable ditch barriers are made of UV-stabilized high-density polyethylene, typically 250 mm and 1000 mm in height and length. These devices are firmly anchored to the ground and capable of reducing water runoff for storm channels and highway ditches. Additionally, it is a sustainable and lightweight alternative to conventional check dams.

Silt Fence

A slit fence is a temporary structure used for sediment control to protect the nearby water bodies typically set up at construction sites. The wood or metal post is positioned, and the geotextile design fabric, which is water-permeable, is stretched around it. When properly installed, it will do an adequate job of controlling sediments and preventing soil erosion. There are three types of silt fences; while the same geotextile fabric is usually used for all, the only difference is in height.

  1. Type A – 36” in height
  2. Type B – 22” in height
  3. Type C – 36” in height, reinforced with wire mesh


Seeding refers to the process of growing vegetation. Implementing this method on your property, especially in distressed areas, will drastically reduce social erosion and sediment loss. Seeding protects the bare soil surface from heavy water runoff that displaces sediments and erodes the soil. This technique is one of the simplest and easiest erosion and sediment control solutions. The various types of applications include:

  1. Hydroseeding
  2. Hydromulching
  3. Broadcast seeding and harrowing
  4. Mechanical drill seeding
