LUDWIG Kunststoffe GmbH - Services  

Installation

Particularly with higher-quality synthetic sealing membranes or more complex seals, it is not enough to just deliver the materials. This is why LUDWIG Kunststoffe GmbH also provides you with a service enterprise specialising in such functions (installations). We deploy staff certified according to WHG § 19 with valid synthetic welding certificates in compliance with the DVS standard.

We can install the following types of synthetic sealing membrane for you in the fields of road construction, civil engineering, horticulture and landscaping:

  • HDPE
  • LDPE
  • PP
  • PVC
  • EPDM

Over the last few years, bentonite mats have established themselves more and more as an economically viable alternative to synthetic sealing membranes and mineral seals in certain branches (ground water protection, storm water retention...):

  • Bentonite mats

From the geosynthetics branch we install:

  • Nonwoven materials for concrete road construction
  • Geogrids (slope stabilisation, base course reinforcement, reinforced earth...)
  • Drainage mats
  • Erosion control (also jute and coconut)

General information on installations

The following apply mutatis mutandis when conducting sealing work:

  • DIN 18195 structural waterproofing
  • AIB - Directive for the Waterproofing of Engineering Structures
  • VOB/B – the latest version of the installation guidelines produced by the manufacturer
General conditions

Additional services that were not identifiable at the point of the original inquiry, such as seals on other openings or buildings, unless specifically shown in the quotation, are charged separately.

Insofar as there is no detailed plan outlined in the original tender, we assume a slope incline of max. 1:2.5 and a large-scale installation.

Costs for external quality control and other test costs are not included in the price.

Interruptions to sealing work for which we are not responsible are invoiced at an hourly rate of 42 Euro per skilled worker hour.

Interruptions for which we are not responsible and which require us to return to the site are invoiced at 650 Euro per new site visit.

The accurate formation level at the bottom and slopes of the construction site must be maintained in a usable state for the duration of the sealing works. Larger areas must be excavator-accessible. The degree of compaction should be 95% of the standard proctor density (where relevant, additional technical instructions for earthworks – ZTVE – should be observed).

All earth, concrete and other incidental works necessitated by the sealing work should be conducted on the construction site according to the progress of the sealing work.

Once the sealing work has been completed, a joint measurement of the finished work must be carried out.

The following must be provided at the construction site:

  1. Delivery of suitable and easily movable scaffolding
  2. Material transport between material storage premises and installation site. This also applies to the installation of lifting devices
  3. Electricity supply at the respective installation sites for the operation of welding and other equipment
  4. Use of the available facilities (e.g. sanitary facilities, construction site accommodation facilities)
  5. Storage facilities for materials in an open, fenced-off area
  6. In the absence of any other arrangements, our materials will be delivered using heavy goods vehicles. The customer is responsible for proper unloading and storage.
Specific preconditions for the installation of synthetic sealing membranes

Where necessary, pipe passages at the construction site are to be furnished with loose-type and full-face flange to ensure seamless installation of the seal.

Structures and concrete surfaces on the construction site must have a smooth upper surface i.e. be free of nests and ridges or, if required, an appropriate plaster application must be provided to accommodate the seal.

To safeguard against wind suction on the construction site, plaster, composite stone paving, a layer of sand or sand sacks should be provided. This should be done very carefully to avoid damage to the synthetic sealing membranes.

Lateral mounting: connecting height for synthetic sealing membrane should be at least 0.30 m above the water level.

All heights for wall seals should be provided at the construction site. Heights must be at least 0.30 m above the highest water level.

All wall seals at the construction site should be provided with protection e.g. protective masonry.

Required working area for wall sealing, according to the AIB, of at least 1.0m width.

Specific preconditions for the installation of bentonite sealing mats

Punctual completion of flat surface. According to the manufacturer's requirements, installation should take place on a stone-free, preferably rolled, dry flat surface. Maximum permissible misalignment in compliance with ZTVE: 3cm.

HGV-appropriate access to the construction site must be provided.

The customer must provide a vehicle (usually an excavator) and driver for the installation of the sealing mats.

The customer is responsible for water management during the construction period to ensure trouble-free installation.

Penetrating water on the construction site must be prevented.

After installation and site measuring, inspection and approval must be carried out immediately.

The customer must ensure that an earth covering is applied within 24 hours of installation.
