Modern inner-city civil engineering
In inner-city civil engineering projects amidst existing pipes, their route and installation depth are often unclear. This is one of the reasons why utilities from all media sectors require manual labor for work in the immediate vicinity of supply lines. This cannot be carried out cost-effectively. Contractors are forced to choose daily between risking the excessive use of hydraulic excavators or the safety of manual labor at a high price. The safest and most economical alternative to manual excavation is the use of a suction excavator.
Exposing house connections
One example of the use of suction excavators is the quick and economical creation of house connections for all media. The use of suction technology enables targeted and thus minimized excavation of the excavation pit, which leads to a significant reduction in follow-up costs. Traffic disruptions are significantly minimized due to the smaller space required and significantly shorter construction times.
Modern Trenchless Pipeline Construction
Whether for the creation of start and finish pits, the extraction of bentonite, or as an important component in the modern keyhole method, the suction excavator is also very well suited for trenchless pipe laying.
TREE ROOT REHABILITATION
Compaction and waterlogging are the two most common reasons that lead to time-consuming restoration work in the root zone of trees. If the oxygen content in the soil drops below 13 percent, root growth is no longer possible. Many trees die or direct their roots to the upper areas, where they then pry up curbs and turn paving slabs into dangerous tripping hazards. The use of a suction excavator ensures the gentle and time-saving exposure of the entire root system without damaging it. The use of a compressed air lance is helpful for very cohesive soils. This blasts open the upper, solid soil layer without damaging the roots, making the removal of the soil easier and faster. For many cities and municipalities, environmentally friendly replanting and the replacement of contaminated soil using a suction excavator are of utmost importance.
FLAT ROOF RENOVATION
More and more clients are using suction excavators specifically for renovation projects on flat roofs, garages, high-rise buildings, or large industrial buildings. Instead of laborious and time-consuming manual labor, the use of RSP technology has proven itself in this field many times over. Even over longer distances and at greater discharge heights, old gravel, chippings, sand, roof substrates, and other materials are vacuumed up quickly, reliably, and cleanly.
BUILDING RENOVATION
In addition to civil engineering, building renovation is an important application for our suction technology. Bulk material, construction rubble, excavated and demolished material are vacuumed up effectively and time-savingly. The exposure of foundation walls, exterior walls, tanks, earth bunkers, and septic tanks, as well as basement renovation, basement lowering, and flat roof renovation are other demanding applications in this field. With the help of hose extensions, hard-to-reach areas can be easily reached and longer suction distances can be easily overcome.
PIPELINE RENOVATION
To ensure the operational safety of gas pipelines, various methods are used for the renovation or repair. External renovations allow the pipes to be exposed quickly and safely. When renovating the inner pipe walls, the loosened deposits are vacuumed away.
CLEANING OF INDUSTRIAL FACILITIES
The goal of industrial cleaning is to maintain the functionality of machinery and equipment and to extend their service life. Chemical plants often contain difficult-to-access and hazardous areas that require thorough cleaning at regular intervals. RSP's high-performance suction dredgers are ideally suited for these tasks. They can easily vacuum over long distances. With the installed gas detection and grounding system and a remote control in explosion-proof design, they meet the safety requirements of such facilities.
PORT FACILITIES
At bulk material handling sites, heavy contamination and material losses occur. The suction dredger offers the possibility of returning the extracted material to the processing cycle. The suction dredger is also ideal for cleaning storage tanks or containers. It can easily vacuum solid and liquid materials over long distances, safely and quickly.
BIOGAS PLANTS
To minimize digester downtime, maintenance work in the digester or when replacing agitators is the ideal time for simultaneous cleaning. A simple solution that allows for effective cleaning even in confined spaces is the use of a suction dredger. Settled layers, deposited sand, grass residue, raw ash, and sludge can be quickly removed with the help of the suction dredger and the additional RSP Suction Worm.
DEFECTIVE SUPPLY LINES
The rapid repair of defective supply lines is a key requirement for many network operators. The fully equipped RSP suction excavators, combined with a wide range of accessories, enable rapid and self-sufficient operation. This allows supply security to be restored much more quickly.
WATER
In the event of pipe bursts, the damaged line can be exposed even if water continues to leak. The high airflow ensures immediate suction of the escaping water, so that repair work can be carried out without any problems. The use of additional wastewater pumps is not necessary.
ENERGY AND COMMUNICATIONS
The consequential costs due to damage to the power system amount to several million euros annually. The rapid deployment of an RSP suction excavator minimizes repair times and thus also the consequential costs. Whether insulation damage or faults in the connecting joints, the damaged areas can be probed very quickly and without damage using a suction excavator. The suction airflow itself does not pose a threat to buried pipeline systems. Thin power or telecommunications lines offer a small surface area exposed to air pressure and thus little impact, while large cables and pipes are protected by their inherent stability.
Snow Load Removal from Flat Roofs
We guarantee our partner companies short-term and efficient snow removal when the load limits of flat roofs are exceeded, based on snow load monitoring. Snow removal over longer distances is easily possible with our RSP suction excavator and our Amphitec air conveying system.

Keyhole - The Keyhole to the House Connection
This technology offers numerous advantages. House connections are often associated with traffic disruptions and complex surface repair work. This doesn't have to be the case! With the keyhole technique, gas, water, and FTTH house connections are laid from the main line in the street to the house – and this from a borehole with a diameter of just 650 mm. After the road surface is opened, a suction excavator gently extracts the keyhole down to the main line. The drilling rig and all necessary work for the line installation are carried out from the surface. The advantages of the keyhole method are obvious. Freshly constructed road surfaces are not torn up. The circular hole has no impact on the tension and load-bearing capacity of the soil and road surface. Only minimal civil engineering work is required. This avoids subsequent costs due to surface damage. After completion of the work, the core is reinserted with special mortar without any additional asphalting costs. Traffic disruption is reduced to a minimum.
NATURAL DISASTERS
In recent years, various natural disasters have increasingly struck Europe. After heavy rainfall that led to severe flooding, suction excavators were deployed as disaster relief workers. Whether it was debris, gravel, or mud, they effectively cleared streets, basements, or hard-to-reach areas. Suction excavators are also used to support cleanup efforts in the event of landslides and rockfalls caused by persistent rain and the associated consequences, such as spills, and can complete the cleanup in a very short time.
TUNNEL MAINTENANCE
Suction technology has now become established not only in construction but also in cleaning and retrofitting work. What was previously done laboriously and expensively by hand is now accomplished with suction excavators at exceptional speed. Cleaning tunnel slotted gutters can be completed overnight without causing major traffic disruption.
RETROFITTING SAFETY TECHNOLOGY
To comply with legal regulations, many tunnels require retrofitting of safety equipment. To carry out this work, the installed cables in the individual shafts must be exposed. These shafts are filled with sand for fire protection reasons. The material is vacuumed out quickly and without risk of damage to the installed power and communication lines. After completion, it can be reused.
TRACK BED RENOVATION & TRACK CLEANING
The ballast bed on track systems requires maintenance because proper drainage of rainwater into the substructure must always be ensured. Ballast needs its edges and gaps to properly perform its function. At some point, the old, blunt ballast must be replaced with new, sharp-edged ballast. Due to limited space, excavating the ballast between the sleepers can usually only be done manually. The suction excavator is a quick alternative to expensive manual labor. Its powerful airflow effortlessly and quickly extracts the ballast even from the tightest gaps. The material is temporarily stored in the collection chamber and can later be easily cleaned or disposed of.
TRACK BED CLEANING
Transport companies and railway administrations attach great importance to clean stops and track sections. Newspapers, cups, cigarettes, etc. carelessly discarded by passengers are not only unattractive accessories, but can also pose a serious hazard if unfortunate circumstances occur. The grinding particles that accumulate after regularly required grinding work on the railhead must also be removed from solid track surfaces. The combination of a suction excavator and rail-to-rail technology enables fast and efficient cleaning of contaminated areas.
Protecting our environment is humanity's greatest responsibility. Nevertheless, unforeseen disasters often occur. RSP's suction technology can help with this task. This includes vacuuming contaminated soil or cleaning sewage shafts and roadside ditches after accidents. Natural disasters often leave traces of devastation in their wake. The suction excavator quickly and safely removes volcanic ash, debris, mud, or snow masses from streets, squares, and rooftops.
