  Groundwater Monitoring for Construction Sites

  All construction affects groundwater and a water management plan will be required. From deforestation to urbanisation, from holes to heaps and dams to drains, they all have an affect on the groundwater. Deforestation causes an increase in the rate of run off of rainwater resulting in lower percolation of precipitation into the soil and a consequent increase in soil erosion leading to slope instability, hence land and mud slides. The increased rate of run off can cause small streams and large rivers to rise and flood in a shorter time, but also to dry up sooner. These conditions cause great difficulties for subsistence farmers in developing countries. Urbanisation also causes faster run off because of the non permeable surfaces such as roads, roofs and car parks. This also creates drainage problems that can lead to contamination and erosion of natural water courses.

  Civil engineering applications

  Civil engineering jobs in water are typical for Watermaster Classic. Watermaster is ideal when e.g. embedding cables and pipes in the bottom and it can also do other kinds of maintenance work effectively. The harder the conditions are, the greater Watermaster`s advantages compared to other technologies. The machine moves to the site with its own propulsion system and remote controlled spuds give proper anchorage for steady and efficient excavating work as well as for cable mounting.

  Monitoring of VOCs in Porewater

  Monitoring VOCs in porewater in the unsaturated zone is now possible.
  
  Sorbisense regularly offers new options for using the patented Sorbicell, which is used to monitor surface water, wastewater and groundwater.
  
  The latest is almost as “ground-breaking” as the SorbiCell itself. Until now it has been difficult, if not impossible, to directly monitor for volatile substances in pore water in the unsaturated zone. But the environmental consultancy firm Ejlskov A/S in Aarhus combined the use of Sorbisense sampling equipment with the proven technology of soil water samplers. With this combination, a practical new method is made available, which allows for monitoring the presence of porewater-dissolved VOCs above the groundwater table. This provides a significantly improved basis to define and determine the leaching risk to the groundwater, and thus allows for better and more cost-efficient decisions to prevent the pollution in reaching the groundwater.
  
  A simple construction with multiple options
  
  The application uses SorbiCell VOC combined with suction cells, soil water samplers. When installed correctly, and applied with the correct procedures, the suctions cells extract capillary bound water from the soil matrix. The system demands no other resource than a container that is put under vacuum. The vacuum in the container then ensures a flow through of the Sorbicell over a period of time, fx. 2-3 weeks. The method is highly suitable for monitoring a site over longer periods of time.

  Erosion & sediment control solutions for costal/beach region

  Coastal erosion is the wearing away of land or the removal of beach or dune sediments by wave action, tidal currents, wave currents, or drainage. Removing sand and other materials from beaches and dunes due to tidal storm surges and construction purposes causes massive beach erosion damages and land loss of seashores, thus destroying the natural heritage of the coast and reducing the vibrancy of the tourism industry. Uprooting vegetation from coastal areas destabilises beaches and clearing sites inland results in increased soil and dirt particles being washed offshore and smothering coral reef systems.

  Vacuum excavation solutions for locate underground utilities / soft dig / pot holing

  Vacuum excavation is fast becoming a best practice in the field of construction and site excavation. Why? Because it uses jets of air (air excavation) or water (hydro excavation) to loosen soil, instead of a heavy metal claw. After loosening, the soil is pulled out of the ground through an air vacuum hose to a debris tank for later disposal or back-filling. Using non-destructive technology can quickly, safely and economically excavate in areas inaccessible to conventional digging equipment like backhoes and trenchers.
