Choose the monitoring level that matches your project needs

Not every project requires the same level of automation and control. SENSOR DDS® systems therefore offer several levels of waterproofing liner and geomembrane monitoring – from an alarm-based solution to a fully automatic system with precise defect location. The right solution depends on the type of structure, operational risk and required response speed.
All systems we supply are custom-manufactured according to the specifications of each individual project and in accordance with the international quality standard ISO 9001:2015 and environmental management standard ISO 14001:2015. This approach ensures a high level of workmanship, system reliability and long-term functionality even under demanding operating conditions.
In manufacturing, we use only high-quality components with long service life, high resistance and proven technical reliability. All key elements have BAM certification (Bundesanstalt für Materialforschung und -prüfung – Federal Institute for Materials Research and Testing), which is one of the most recognised guarantees of quality and durability in the field of construction and waterproofing systems.
BAM certification guarantees the service life of individual components in the range of at least 30 to 100 years. As a result, we provide solutions with high investment security, minimal maintenance requirements and truly long-term waterproofing liner integrity monitoring.
The individual systems differ not only in their level of automation, but also in how they evaluate and respond to a defect once it occurs. This makes it possible to design a solution according to the complexity of the project, the required response speed and the desired level of operational certainty.
Medium level of protection

SENSOR DDS® LAM - Alarm Module with Subsequent Defect Location

SENSOR DDS® LAM is an alarm detection system that increases the level of waterproofing liner protection. Its role is to provide a real-time warning that a problem or suspected damage has occurred in the waterproofing liner.

LAM can be combined with the LMS system - creating a built-in measuring network while adding an alarm function. If the system detects a problem, it alerts the responsible person and a Sensor technician comes to the site to perform expert measurement and locate the defect.

However, LAM does not have to be used only in combination with the LMS system. It can also operate as a standalone alarm module. If a permanent LMS system - meaning a built-in sensor network - is not present in the structure, leak location after the alarm is carried out using portable systems SENSOR DDS® MIT or SENSOR DDS® Mobile.

SENSOR DDS® LAM - alarm system for immediate leak detection

SENSOR DDS® LAM is a reliable alarm system designed for projects where immediate detection of a geomembrane leak is required. The system is primarily designed for installation in a double-liner waterproofing system and is intended to work together with the SENSOR DDS® LMS periodic monitoring system, which is then used for precise defect location.
During operation, LAM continuously monitors the condition of the waterproofing liner and automatically switches to alarm mode if the liner is damaged. The system immediately alerts the responsible persons with an acoustic and visual signal and can also send a notification by SMS or email.
The monitoring panel can be installed indoors or outdoors and is designed to operate reliably even under demanding operating conditions. The system can be equipped with a UPS backup power supply or a solar power source, enabling operation even at sites without a stable electrical infrastructure.

SENSOR DDS® LAM provides fast information that damage to the waterproofing liner has occurred. Precise leak location is then carried out using the permanently installed offline SENSOR DDS® LMS system, which identifies the exact defect location. If the LMS system is not permanently installed, leak location is performed using portable systems SENSOR DDS® MIT or SENSOR DDS® Mobile.

Thanks to its robust design and the use of proven industrial technologies, LAM provides an effective and cost-efficient solution for continuous monitoring of waterproofing system integrity.

Semi-automatic Waterproofing Monitoring with SENSOR DDS® RMS

SENSOR DDS® RMS is an online geo-electrical monitoring system designed for continuous integrity control of waterproofing liners and geomembranes. A sensor network is permanently installed beneath the liner, continuously monitoring the condition of the waterproofing system and immediately triggering an alarm if a leak occurs.

The main advantage of the system is remote supervision without the need for regular technician visits to the site. Measurement data is transmitted via Sensor Cloud, allowing the system to be monitored and evaluated remotely from a monitoring centre. Authorised persons also receive immediate alerts by SMS or email. If the project does not require online remote supervision, an alternative can be periodic waterproofing monitoring.

After an alarm is triggered, the system is evaluated remotely and the collected data is then processed by Sensor. The client receives information about the precise location of the liner damage, including GPS coordinates, usually within 48 hours of the alarm being triggered.

The complete solution consists of permanently installed components – sensors and cables – together with an above-ground monitoring centre. Each sensor is connected separately to ensure the highest possible data transmission quality and system reliability.

SENSOR DDS® CMS - fully automatic waterproofing monitoring

SENSOR DDS® CMS represents the most advanced geo-electrical system for continuous 24/7 integrity monitoring of waterproofing liners and geomembranes. The system is designed to automatically detect the occurrence of a leak and at the same time precisely identify the location where the defect has occurred.

Unlike solutions that require scheduled measurements or technician intervention, CMS operates fully automatically and continuously. The waterproofing system is monitored in real time and, if liner damage occurs, the system immediately evaluates the leak and alerts the responsible persons via alarm, SMS or email.

The detection system is complemented by a monitoring centre that collects and evaluates all data from the sensors. The control panel can be located directly in the technical room of the structure or in an external monitoring kiosk adapted for demanding operating conditions.

The system is based on robust SENSOR detection tiles installed between two geomembrane layers – for example HDPE, PVC or bituminous liners. These tiles divide the monitored area into individual sectors that are permanently controlled. This makes it possible to identify the area where damage to the waterproofing layer has occurred very quickly.

When this system is used in a single-liner waterproofing system, the sensor network – typically installed in a 5 × 5 m grid – is placed directly beneath the waterproofing liner, similarly to LMS or RMS systems. This solution enables continuous monitoring of the geomembrane condition and immediate detection of any damage or leak occurrence.

The monitoring system then provides 24/7 geomembrane control, continuously throughout the entire service life of the structure. Thanks to permanent supervision, waterproofing defects can be identified early, the exact location of damage can be determined and the risk of water ingress into the building structure can be minimised. This system significantly increases structural safety, extends the service life of the waterproofing system and reduces the cost of subsequent repairs and remediation.

Permanent monitoring systems are installed during the construction of the waterproofing layer. Sensors, detection elements or detection tiles are built directly into the waterproofing system build-up, most often beneath the geomembrane or between individual insulation layers. This is the stage where the system can be set up to monitor the integrity of the waterproofing liner throughout the entire operation of the structure.

One-time testing verifies the condition of the waterproofing layer at a specific moment, while permanent monitoring continuously tracks its condition during operation.

Permanent waterproofing monitoring is used mainly in projects where long-term geomembrane or waterproofing liner integrity is critical.

In these applications, early leak detection is essential for protecting the environment, technological infrastructure and the investment itself.

It depends on the type of system.

  • SENSOR DDS® CMS operates fully automatically and does not require manual measurements
  • SENSOR DDS® RMS enables remote supervision and data evaluation without the need for regular site visits
  • SENSOR DDS® LAM provides an alarm when a defect occurs, and subsequent leak location is carried out using the offline SENSOR DDS® LMS system, SENSOR DDS® MIT or SENSOR DDS® Mobile

All systems are designed to minimise the need for manual inspections during operation and shorten the time between leak occurrence and the subsequent response.

From the investor’s or operator’s perspective, the main benefit is risk management throughout the entire service life of the project.

  • early detection of geomembrane or waterproofing liner damage
  • fast response when a leak occurs
  • reduction of environmental and operational risk
  • protection of the investment in the waterproofing system
  • long-term integrity monitoring of the liner during operation

For projects with high safety and reliability requirements, permanent monitoring is an important tool for controlling liner integrity throughout the entire operational phase.

The decisive criterion is the required level of automation and the way the defect is evaluated.

  • SENSOR DDS® RMS is suitable where online supervision, remote data evaluation and subsequent precise defect location are important
  • SENSOR DDS® CMS is suitable for projects where immediate automatic identification of the damaged sector is critical, without the need for manual intervention

If the project requires the maximum level of automation and immediate information about the leak sector, SENSOR DDS® CMS is the more suitable solution. If the priority is remote supervision and operational data evaluation from the monitoring centre, SENSOR DDS® RMS is the right choice.

No. SENSOR DDS® LAM is an alarm system that informs the operator that a leak has occurred, but it does not determine the exact defect location by itself.

  • the system immediately activates an alarm when the liner is damaged
  • it alerts the operator locally or via SMS and email
  • precise leak location is then carried out using the offline SENSOR DDS® LMS system

LAM is suitable for projects where the priority is fast information that a defect has occurred, while subsequent leak location is handled through a permanently installed offline system.

Waterproofing monitoring is suitable for projects where long-term leak tightness control, fast response to defects and the minimisation of operational, financial and environmental damage are critical. It is most commonly used on structures and technical systems with a waterproofing liner or geomembrane, where even minor damage can lead to costly repairs, operational downtime or degradation of the structure.

The solution is especially suitable wherever an investor, designer, contractor or operator needs confidence that the waterproofing system remains watertight throughout the entire service life of the structure and that any leak will be detected in time.
